Vespersaurus: The Dinosaur That Ran On One Toe

Vespersaurus paranaensis was a small noasaurine theropod dinosaur from Late Cretaceous Brazil. Whereas most other theropods dinosaurs supported their weight with three toes, Vespersaurus supported its weight with one large middle toe. The two outer toes were held above the ground, similar to the dromaeosaurids. Despite being known from less than half of a skeleton, Vespersaurus still represents one of the most complete noasaurine skeletons known. 00:00 - Introduction 00:36 - Monodactyl Feet 02:30 - Anatomy 03:13 - Classification 04:12 - Filling in the Gaps in Other Noasaurines 05:47 - Feathers? 06:54 - Conclusion
