traversodontids

Traversodontids are a group of herbivorous dinosaurs that lived during the Late Cretaceous period, approximately 99 to 66 million years ago. They are known for their distinctive, tooth-like structures on their tongues, which they used to scrape food from plants. Traversodontids are characterized by their large size, robust bodies, and a unique dental structure. The most well-known species is Traversodon sp., which was discovered in the Hell Creek Formation of North Dakota, USA.

Traversodontids are believed to have been one of the last groups of dinosaurs to go extinct at the end of the Cretaceous period. Their extinction is thought to have been caused by a combination of factors, including climate change, volcanic activity, and the impact of a large asteroid. Despite their relatively short evolutionary history, traversodontids played an important role in the ecosystems of the Late Cretaceous period, and their fossils provide valuable insights into the diversity and adaptations of herbivorous dinosaurs.
