Duality of Argentina’s Dinosaurs – Native Species Compared To Migratory Species

The realm of paleontology that revolves around dinosaurs in Argentina presents an intriguing dichotomy between native and migratory species. Native dinosaurs, as the term implies, are those species that have their evolutionary roots set firmly within the borders of modern-day Argentina.

This encompasses species like the Argentinosaurus, a herbivorous sauropod renowned for its colossal size, and the Carnotaurus, recognized easily by its distinctive horns and predatory lifestyle. These species, among others, represent the unfolding of unique evolutionary trajectories under the local environments of what we now call Argentina.

On the opposite end of this duality are the migratory dinosaurs — species not originally native to Argentina but believed to have reached there due to various factors like ecological pressures, migration for propagation, or continental drift. Among these ranks is the Gigantspinosaurus, predominantly known from other regions like Asia.

The presence of these migrant dinosaurs in Argentina enriches the diversity of the local dinosaur population and hints at prehistorical phenomena like continental connectivity and mass migration. As such, the exploration of both native and migratory dinosaur species adds depth to our understanding of the Mesozoic dynamics and the bustling life it hosted on Argentine lands.
