Types of Duck-Billed Dinosaurs [Names, Habitats, Nests]

“Types of Duck-Billed Dinosaurs” might evoke images of prehistoric creatures waddling by a lakeside, but these fascinating herbivores were far more diverse and widespread than their nickname suggests. From the crested Parasaurolophus to the stout Edmontosaurus, these Cretaceous period mainstays displayed a remarkable array of shapes and sizes. Venturing further into the world of Hadrosauridae, we uncover a spectrum of species that thrived across ancient floodplains and forests. Each type of duck-billed dinosaur possessed unique adaptations: some brandished elaborate head crests possibly used for communication, while others boasted dental batteries capable of processing the toughest vegetation. Their fossilized remains, unearthed from North America to Asia, provide a window into an era when these majestic creatures were the uncontested masters of their domain. This makes me curious, what are the types of duck-billed dinosaurs?


What Are The Types of Duck-Billed Dinosaurs?

Hadrosauridae has two types of Hadrosaurid subfamilies, the hollow-crested Lambeosaurinae, and the non-crested Saurolophinae. There are also Basal Hadrosaurids, which are classified as more primitive or ancestral. Their fossils were found in North America, South America, Europe, and Asia.

These majestic beasts boasted unique anatomy, specifically the flattened and stretched rostral bones in their mouths that gave them that distinct duckbill we all now associate them with. 

It’s interesting to learn more about how the Hadrosaurids or duck billed dinosaurs had lived. Visually, the bony cranial crests made some of the Hadrosaurids strikingly different from other dinosaurs. Yet, there is more to them than just their fascinating duck dinosaur appearance. 

Hadrosauridae, also known as duck-billed dinosaurs, comprise an engrossing variety of species. North America was a common ground for Edmontosaurus and Corythosaurus; the former known for its massive build and the latter recognized by its helmeted skull. Meanwhile, Asia hosted the unique Tsintaosaurus with a unicorn-like crest and the enormous Shantungosaurus, the largest of its kind.

Species like Saurolophus, known for its sharp beak and long, pointed crest, and Anatosaurus, one of the last and largest of its breed, add to the diversity of this family. The Hadrosaurid umbrella also encompasses Gryposaurus, identified by its hook-shaped nasal crest, and cousins like Kritosaurus, Hypacrosaurus, and Prosaurolophus.

In Asia, discoveries like Charonosaurus, similar to the curved-crested Parasaurolophus, and the lesser-known Amurosaurus add to the variety. The lineage can trace back to Bactrosaurus, a simpler dinosaur lacking advanced features, but an essential piece in the Hadrosaurid evolutionary puzzle. The intrigue surrounding the duck-billed dinosaurs, all the way from North America to Asia, remains a focal point in paleontological studies.

The Hadrisauridae are among the most diverse families of dinosaurs, yet they were only composed of herbivores. Consider this:

  • Not a single member of this family became an omnivore or carnivore. They were always plant-eaters, i.e., herbivores
  • Paleontologists often compare them to modern grazers like sheep and cows – we can learn a lot from this comparison 
  • The many types of duck billed dinosaurs diversified into subgroups, so their fossils are found at sites around the world
  • Hadrosaurs lived in multiple habitats and laid eggs that would carry on their family for millions of years in the Late Cretaceous Period

Let’s turn back the clock and learn more about them in this post!

There are three types of Hadrosaurids. The hollow-crested Lambeosaurinae, the non-crested Saurolophinae and the Basal (ancestral) – AdventureDinosaurs

Types and Names – Types of Duck Billed Dinosaurs and What Is the Duck Billed Dinosaur Called?

The Hadrosauridaes or the family of the duck billed dinosaurs are some of the most diverse dinosaurian families out there. They are also one of the earliest dinosaurs ever to be found by paleontologists. 

Hadrosaurids are the earliest fossils in North America, starting with the 1856 discovery of their fossilized teeth. However, despite being one of the earliest ever found, they lived in the Cretaceous Period, the Mesozoic Era’s last period.

Despite being late in appearing in the fossil records, the Hadrosauridaes were some of the most widespread dinosaurs during the Late Cretaceous Period. 

They branched into two subfamilies, while some genus and species of duck billed dinosaurs appeared to be basal, or perhaps didn’t fall into the two subfamilies. The Hadrosaurus is an example of Hadrosauridae’s genus that didn’t get classified in the subfamilies, yet it is still a duck billed dinosaur. 

In the following images, I add the two main clades of duck billed dinosaurs. In the first image, I outline a simplified top-level clade of Hadrosauridae. 

In the next image, a simplified clade of Saurolophidae – the non-crested duck billed dinosaurs.

Lastly, in the following image, I show the Basel Hadrosaurids.

The only species in this genus is the Hadrosaurus foulkii, one of the earliest Hadrosaur fossils.

To give you a general description of how these duck dinosaurs looked like, as their common name suggests, their snout or mouth looked similar to a duck’s bill. They were two-legged dinosaurs that could walk on their hind legs. However, as scientists examined the fossil bones, it suggests that they were grazing animals and, as such, relied on their front legs to walk. 

The Hollow-Crested Hadrosaurids 

The first of two subfamilies of duck billed dinosaur Hadrosaurids are the hollow crested Hadrosaurids from the subfamily Lambeosaurinae. They are classified as such because of the distinctive head crests above their head. The head crest adds more style to their already uniquely-shaped skull. This subfamily is diverse by itself because they have more than ten identified subgroups. 

One of the interesting aspects of these dinosaurs’ head crest is that the head crest is hollow. Some paleontologists suggest that it was part of the nasal passages (or nasal bone) and could be used to make sounds.

Crested Hadrosaurid Where Fossils FoundWhat's Interesting About This Dinosaur?

The members of this subfamily, known as Lambeosaurinae, share the characteristic duck billed or extended rostral bones in their mouths, which are common among all members of the Hadrosauridae family. However, what sets them apart are the distinctive hollow crests on their heads, varying in shapes and sizes. These hollow crests likely served a different purpose compared to the crested members of the other subfamily.

The hollow crests found in all Lambeosaurinae family members are believed to have been used for vocalization and communication. Similar to the pipe of a trombone, these hollow crests could have acted as vocal resonators, enabling the duckbills to produce sounds for various communication purposes. These sounds may have been utilized to warn other members of the herd about potential danger, attract mates, discourage rivals, and facilitate species recognition between different groups.

Recent research conducted in the USA supports the theory of these hollow crests being used for communication. Scientists constructed an exact model of a lambeosaur’s crest and conducted experiments, which revealed that these duckbills could have produced booming, resonant notes similar to a foghorn sound. These powerful vocalizations would have carried over long distances, providing an efficient means of communication within the herd and between different herds.

It is fascinating to note that the bony crests, although hollow, were part of an extension from the skull. They developed and changed position as the dinosaur grew, shifting from the nose to the back of the skull as the individual matured. However, the elaborate nature of these hollow crests made them structurally vulnerable, resulting in fractures and injuries. Fossilized skulls of the Parasaurolophus walkeri, for example, often exhibit signs of breakage.

In addition to their unique head crests, all hollow-crested Hadrosaurids, including the Lambeosaurinae, possessed the ability to run on all fours or walk on two feet, much like other members of the Hadrosauridae family. This flexibility in locomotion likely played a role in their adaptation to their environment.

It is worth mentioning that a transitional hadrosaurid named Gryposaurus displayed a distinct formation of the head crest. Initially positioned more on its nose when young, as it grew older, the crest moved backward on the skull. This observation, based on the examination of different aged fossil skeletons, highlights the morphological changes these dinosaurs underwent as they matured.

While scientists can only speculate about the specific nature of communication facilitated by the hollow head crest, it is believed that duckbills, including the Parasaurolophus, exhibited social behavior and possibly herded with other herbivore dinosaurs. The hollow crests may have played a crucial role in coordinating movements and maintaining social cohesion within and between herds.

The hollow crests found in the Lambeosaurinae subfamily of duckbills served as unique adaptations for vocalization and communication. These elaborate structures acted as vocal resonators, allowing these dinosaurs to produce resonant sounds for various purposes, including warning, mating, rivalry, and species recognition. While vulnerable to fractures and injuries, these hollow crests played a significant role in the social behavior and interaction of these dinosaur herds.

The members of this subfamily all have the same duck billed or extended rostral bones in their mouths that all members of the Hadrosauridae have. Yet, what is distinct in this subfamily are the hollow crests on their heads that vary in shapes and sizes. 

These hollow crests may have served a purpose different from the crested members of the other subfamily. The hollow crests that all Lambeosaurinae family members have are most likely used for vocalization and communication purposes.

Although the head crests were hollow, they were bony crests, and we are lucky for this because they could be fossilized. The bony crests were part of an extension from the skull. It’s interesting to note that these bony crests developed and changed position as the dinosaur grew. A young dinosaur would have its crest more toward the nose and as it matured, more backward on the skull.

However, a hollow head crest may be prone to injuries or, in some cases, fractures. Multiple fossilized skulls of the Parasaurolophus walkeri are broken or fractured. More about this crested dinosaur will be covered below.

 It also doesn’t help that most of these hollow crests are too elaborate to be structurally strong. Lastly, like all members of Hadrosauridae’s big family, all hollow crested Hadrosaurids can run on all fours and walk with two feet.

One unique formation of the head crest is found from a transitional hadrosaurid named Gryposaurus. This dinosaur had a nasal head crest that initially was positioned more on its nose when young, and then when it grew older, it moved backward. (Source) Scientists have found different ages of fossil skeletons and determined that the dinosaurs looked different at one-year-old and three-year-old.

The hollow-crested Parasaurolophus could walk on its hind legs, but would walk on all four legs when grazing. – AdventureDinosaurs

One of the most well-known crested hadrosaurid dinosaurs was Parasaurolophus. This dinosaur lived in North American and the Asian regions during the late-Cretaceous. (Source) The Parasaurolophus walkeri is estimated to have reached 9.5 m (31 ft), and its weight is estimated at 2.5 tonnes (2.8 short tons). 

The crest of the Parasaurolophus, which is one of the most identifying features of this dinosaur. Paleontologists suggest that the use of the crest is one or a combination of:

● Using the crest as a weapon against predators or in mating battles

 Used as a type of snorkel when in water (rivers and marshes)

● Used as a way of moving plants out of the way

● Used as a way of communication, in which the hollow crest was blown like a horn

The Parasaurolophus’ behavior was similar to other hadrosaurs, especially its herd behavior. They were social, and scientists can only guess how communication via their hollow head crest could have been. Paleontologists suggest that they could have herded with other herbivore dinosaurs as well. (Source)

The Lambeosaurus was a Lambeosaurine Hadrosaur that had a recognizable crest that was hollow, with air chambers. As mentioned, some scientists think that the hollow display crests could be used for communication as it could make a sound.

The beak had the distinctive duckbill shape, and like all Hadrosaurs, it was herbivorous and walked on its hind legs and forelegs when grazing. It is suggested that the display crest could also be used for mating visual displays. 

The Lambeosaurus fossils have been found in North America (Canada, Baja California), Europe, Mongolia, China, and Russia. It was a late-Cretaceous Hadrosaur, living up until the mass-extinction event.

The Non-Crested Hadrosaurids

The other type of duck billed dinosaurs is a subfamily that belongs to the Saurolophinae or the non-crested Hadrosaurids, although some species of this subfamily do have crests. The crests that some of the members of this family have been different. They are not hollow head crests like in the first subfamily, and also they are differently shaped. 

This subfamily has species equipped with a solid crest that is perfect for skull bashing, instead of vocalization. Most of the subfamily members do not even have a crest, hence the name of the subfamily.

Non-Crested Hadrosaurid Where Fossils FoundWhat's Interesting About This Dinosaur?

This subfamily members also have the common characteristics of all duck billed dinosaurs, the extended rostral bones, and the bipedal-quadrupedal walking abilities. As for what sets the subfamily members different from their hollow-crested cousins, some have solid crests while some don’t have any. Its nose shape was a “humped nose” and had the typical duckbill shaped snout. 

The members of this subfamily tend to be more defensive with their solid crests and colonial nesting habits, especially the Maiasaura. 

The Edmontosaurus was a non-crested hadrosaur. However, paleontologists think that they did have a soft head crest, much like a rooster. As it was a duck dinosaur or duck-billed, its snout had rostel bones which made shaped like a duck beak, it walked on its hind legs although used its front legs while grazing. The fossils of Edmontosaurus have been found in North America, mostly in Canada. 

The Edmontosaurus was a non-crested Hadrosaurid – AdventureDinosaurs

The Edmontosaurus annectens, which was found in Wyoming, was an exceptional well-preserved duck billed dinosaur fossil. 

Interestingly, other recent fossils of the Edomntosaurus had preserved the skin impressions and stomach contents, so scientists now know the texture of its skin and what it ate before it died.

A recent fossil discovery (2019) in Texas of a non-crested type of duck billed dinosaur named Aquilarhinus (meaning “eagle snout”) is one of the most complete skulls of this type of dinosaur found in that area. The Aquilarhinus had a shovel-billed snout and lived in the late-Cretaceous period. It is now considered to be a new species of Hadrosaur. (Source)

Gryposaurus was a non-crested hadrosaurid whose fossils were found in Utah, USA. The fossils found were nearly complete, and additionally, the skin impressions have given paleontologists extra information about this dinosaur. The arched nasal crest, which gave the skull the Gyrposaurus a distinctive look, is one of the key identifiers. The nose bone helped to identify the type of Hadrosaurid it was.

One of the interesting things about Gryposaurus is that the fossils show how the scales were distributed along the dinosaur’s neck, back, and sides. It lived in the late-Cretaceous.

The Basal Hadrosaurids 

After the two subfamilies of the duck billed dinosaurs, some hadrosaurids do not fall under either subfamily. Nevertheless, these dinosaurs are members of the Hadrosauridae family because they have all the common characteristics, including the rostral duckbill bones. Scientists believe that they had a common ancestor as well.

Scientists believe that they had a common ancestor as well. Basal Hadrosaurids tend to be of the oldest members of the entire family of duck-billed dinosaurs. Basal, in biological terms, means primitive or ancestral. The most prominent basal Hadrosaurid happens to be the first to be ever found in North America, the Hadrosaurus Foulkii.

As the name implies, the only member of this genus has a unique mouth that almost resembles an eagle’s snout. This one didn’t get to be classified on the two subfamilies because it doesn’t have a crest, while also having a rostral bone that no other hadrosaurid has. You could say its duckbill looks more like a shovel-chinned eagle nose or beak.

In addition to their unique mouth structure, the composition of duck bills is quite fascinating. Duck bills are made of keratin, a proteinaceous substance that is also found in human hair and nails. This means that the material that makes up duck bills is actually quite similar to the material that makes up our own hair and nails.

The presence of keratin in duck bills allows them to serve multiple purposes. They enable ducks and other waterfowl to filter food from the water, scoop and shovel mud, and engage in various behaviors such as courtship displays and aggression. This evolutionary adaptation has proven to be highly advantageous for these birds in their aquatic habitats.

Therefore, while the unique mouth structure of the Hadrosaurus Foulkii resembles an eagle’s snout or beak, it is important to note that the composition of duck bills, including the Hadrosaurids, is made of keratin, similar to human hair and nails. This keratin-based structure provides ducks and other waterfowl with the ability to perform various tasks essential for their survival and behavior in their watery environments.<

Basal Hadrosaurid Where Fossils FoundWhat's Interesting About This Dinosaur?

Basal Hadrosaurids tend to be of the oldest members of the entire family of duck billed dinosaurs. Basal, in biological terms, means primitive or ancestral. The most prominent basal Hadrosaurid happens to be the first to be ever found in North America, the Hadrosaurus Foulkii. 

The Aquilarhinus is another basal hadrosaurid. It is a”shovel-chinned eagle nose” hadrosaurid, a member of the Aquilarhinus genus. 

As the name implies, the only member of this genus has a unique mouth that almost resembles an eagle’s snout. This one didn’t get to be classified on the two subfamilies because it doesn’t have a crest, while also having a rostral bone that no other hadrosaurid has. You could say its duckbill looks more like a shovel-chinned eagle nose or beak. 

The Aquilarhinus was a primitive hadrosaurid. Although it had a crest, it was slightly different from later crested duck billed dinosaurs. It is exciting because scientists can track and hypothesize about the evolution of crested hadrosaurs. Some of the Basal Hadrosaurids have display crests, but not all of them do. 

Some Basal Hadrosaurids had crests, but others didn’t. The Basal Hadrosaurids were older ancestral duck billed dinosaurs – AdventureDinosaurs

Another primitive ancestor to hadrosaurids was the Iguanodon. It was distantly related to the duck billed Hadrosaurs. It was similar to other hadrosaurs as it was a herbivore dinosaur, it walked on its hind legs and its front legs. However, it didn’t have any display crests, and it is known for having a large spike at the end of its thumb. 

The Lapampasaurus is another hadrosaurid that didn’t get to be classified in either subfamily. This extinct genus only has one confirmed species, for now. The discovery was on the Allen formation in La Pampa Province, Argentina, hence the name. 

Since the specimens found are not complete, paleontologists could not classify the genus to the two subfamilies. There is also a huge possibility that it might be a basal species and closely related to the Aquilarhinus and Hadrosaurus.

Habitats – Where Did the Duck Billed Dinosaur Live? Is the Duck Billed Dinosaur a Herbivore?

During the mid to late Cretaceous Period, the climate was different than what we have today. It should be noted that flowers were still new and that the forests back then could have been composed of pines and conifers.

All the different duck billed dinosaurs described above lived during the Cretaceous period and existed until the mass-extinction event. 

The Hadrosaurids Lived Relatively Warm Climates Rich With Grasslands

During this period, the supercontinent Gondwana started to break up; therefore, inland seas were prominent. During this time, sea levels were so high due to the melting of the polar ice caps. The duck billed dinosaurs may have likely lived in a warm temperate Earth filled with internal seaways, ancient deltas, and marshlands.

Paleontologists and paleobiologists estimate that hadrosaurids lived in these types of habitats:

● Grasslands
● Forests
● Savannas
● Rivers and lagoons
● Inland seas and river deltas
● Marshes

Hadrosaurids Were Herbivorous Grazers Like Modern Sheep and Cows 

The Hadrosaurids may have had a paleo diet of horsetails and low growing grasses. All of them were herbivores, plant-eating dinosaurs. 

The prevailing theory is that the duck billed dinosaurs were grazers like modern sheep and cows. This declaration by a paleontologist group was because the specimens’ skull bones and fossilized teeth showed that they were good at chewing. If you’re interested to learn how much a dinosaur tooth is worth, check out my article What’s the Value of a Real Dinosaur Tooth (Single, On Jawbone)?.

The Hadrosaurids were grazing animals with rows of flat interlocking teeth which were good for chewing – AdventureDinosaurs

Some paleontologists suggest that the Hadrosaurids were actually tree browsers like modern-day giraffes. Whatever the case is, some prevailing theories tend to be debunked, just like how the Spinosaurus changed from the semi-aquatic theory to the now fully aquatic theory.

Places Where Fossils of Different Types of Duck Billed Dinosaurs Were Found

Duck billed dinosaurs have been found worldwide but are concentrated in a few key geographical areas. The duck billed dinosaurs’ fossils tend to be more commonly found in North America.

Other discoveries of different types of duck billed dinosaurs in North America include the Edmontosaurus and Parasaurolophus, both found in Alberta, Canada, and the famous Maiasaura in Montana, USA. Other specimens were also found in Asia and Europe.

The skull bones of the Hadrosaurid fossils are perhaps the most important in the identification of what type of Hadrosaurid the dinosaur was. By examining if the skull bones have a head crest or not, examining the shape of the nose and mouth, as well as the teeth, tells paleontologists a lot about the fossils. 

Did Dinosaurs Build Nests? Herds Of Hadrosaurids Nested Close to Each Other

The discovery of the Hadrosaurids was revolutionary because they were proof that some dinosaurs do not fit the “large lizard” depiction. The Maiasaura was famous because it showed something that was not expected of dinosaurs, colonial nestings. 

It means that Maiasaura peeblesorum, otherwise called the “caring lizard,” and other duck billed dinosaurs lived in herds and nested close to each other. Nicknamed “egg mountain” in Montana, it was excavated and found to have 14 dinosaur nests, not 14 eggs but 14 nests with multiple eggs.

It was exciting to find that Maiasaurs did nest building so close to each other. Although the materials used to build the nest were not fossilized, you could see that they had shaped nests and the eggs were in a circular order, indicating a nest structure. If you ever wondered how valuable a dinosaur egg is, check out my article How Much Would A Real Dinosaur Egg Be Worth?

The place in Montana where these dinosaur nests were found was a place known as Egg Mountain, near a town named Choteau. The nesting site with all the nests of dinosaur eggs was found in July 1979, the first ones discovered by Fran Tannenbaum. 

Nests of dinosaur eggs have been found in many places around the world, but Egg Mountain in Montana, USA is a special place as a duck billed dinosaur nesting ground – AdventureDinosaurs

The amazing thing about Egg Mountain is that for 40 years, and counting, dinosaur eggs, fossils of a baby (juvenile), and adult dinosaurs such as the Maiasaura peeblesorum have been discovered and can now be studied. (Source)

The site also points to how dinosaurs lived together in herds, nested, and took care of their young. 

The Hadrosaurids Cared For Their Young Even After Hatching

The Hadrosaurids are also known to care for their young even after hatching. Fossil evidence shows that herds of Hadrosaurids migrated to meet the nutritional demands of their young. This habit is almost similar to how zebras and wildebeests migrate the African continent clockwise. 

The fossilized nests of Maiasaurs at Egg Mountain in Montana changed a lot of the previous thinking as to how dinosaurs laid eggs and whether they took care of their young or not. 

Since multiple ages of dinosaur fossils were found – babies, juveniles, and adults – it suggests that there was some care given to young dinosaur hatchlings. Additionally, as young dinosaurs were more in danger by predators, by staying in herds and protecting their young, they had a better chance at survival. 

How Was a Duckbill Dinosaur Like an Antelope?

Duckbill dinosaurs and antelopes share several similarities, making them quite comparable. Firstly, both animals belong to the herbivorous category, relying on plant-based diets for sustenance. Additionally, they both possess four legs, which aids in their mobility and movement within their respective habitats. Furthermore, both species have evolved specific adaptations that allow them to thrive in their ecosystems.

One noteworthy similarity between duckbill dinosaurs and antelopes lies in their specialized feeding apparatus. Duckbill dinosaurs possess scissor-like bills, specifically designed to efficiently consume leaves and tough vegetation. Similarly, antelopes have long, narrow faces and specialized molars that enable them to adeptly grind coarse grasses, which form a significant portion of their diet.

Another shared characteristic between these two animals is their ability to swiftly navigate their surroundings. Both duckbill dinosaurs and antelopes are known for their remarkable speed, allowing them to escape from potential predators effectively. This agility plays a crucial role in their survival, as it increases their chances of evading danger and ensuring their long-term existence in their respective ecosystems.

It’s amazing, but duckbill dinosaurs and antelopes exhibit various resemblances. Their herbivorous diets, possessing four legs, and adaptations such as specialized feeding apparatuses and swiftness contribute to their overall similarity in appearance and behavior.

How To Draw A Duckbill Dinosaur

To successfully draw a duck bill, follow these steps:

  1. Start by drawing an elongated oval shape that is slightly curved. This shape will serve as the base of the duck’s bill.
  2. Extend two curved lines from the sides of the oval to give the bill its characteristic bumpy texture. These lines should connect smoothly with the oval at one end and curve outward at the other end.
  3. Draw a thin curved line on top of the oval. This line represents the upper part of the beak and should follow the curve of the oval.
  4. Now it’s time to add the nostrils. Place two small circles on either side of the bill, towards the middle. These circles should be spaced evenly and positioned at a slight angle.
  5. To bring out the details of the bill, use a dark marker or pencil. Start by drawing several small lines on the top and bottom of the bill. These lines should form a zigzag pattern, adding texture to the surface of the bill.
  6. Finally, complete the bottom part of the beak by drawing a curved line that connects to the base of the bill. This line should follow the curvature of the initial oval shape, creating a seamless transition.

By following these steps, you will be able to draw a duck bill with accuracy and detail. Remember to practice and refine your techniques to achieve the desired result.

What Are the Duckbills’ Defense Mechanisms?

Duckbills have an array of defense mechanisms that safeguard them from predators. One key strategy utilized by duckbills is their ability to dive underwater when threatened, effectively escaping and eluding predators. Additionally, their bills and caps serve as protective shields for their eyes, faces, and heads, shielding them from potential harm.

When danger persists, duckbills possess the skill of swift takeoff and flight, allowing them to evade threats efficiently. Their webbed feet are not only essential for swimming at high speeds but also aid in avoiding danger by swiftly maneuvering through water.

Duckbills often employ camouflage, blending their feathers with their surroundings, making it challenging for predators to spot them. They also exhibit a defensive behavior of gathering in large groups, rendering it difficult for predators to single out an individual duck.

Moreover, they communicate with each other using loud, high-pitched quacks to alert fellow ducks of impending danger. In terms of physical defense, duckbills are equipped with strong hind legs, which they utilize for kicking potential attackers and running away from threats.

Their excellent vision plays a crucial role in detecting dangers in their environment. In some duckbill species, bony crests adorn the backs of their heads, serving as an additional mechanism of defense.


What a sight it must have been millions of years ago to see herds of duck billed dinosaurs, nesting, and taking care of their young. Probably, if they had Parasaurolophus crests, you might even be able to hear horn sounds coming from the herds. 

If those herds didn’t have head crests, such as dinosaurs like Edmontosaurus, the imagination wonders if they would really be grazing similar to the way modern-day cows are in a field. 

Luckily, we have the museums to see the fossil remains of these interesting and unique duck billed dinosaurs.
