Extinct Era on Instagram: "Ornitholestes lived about 150 million years ago in what is now North America, alongside giants like Allosaurus and Diplodocus. At around 2 meters (6-7 feet) long, it was lightly built with long legs and grasping hands that made it quick and agile. Its sharp, recurved teeth suggest it fed on small prey such as lizards, mammals, and young dinosaurs, filling a role that the larger carnivores did not. 📹 Dinosaur Revolution (2011)"
