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)"

Extinct Era on Instagram: "Spinosaurus was one of the largest predators of the mid-Cretaceous, a semi-aquatic hunter that fed on fish and shoreline prey in what is now North Africa. It shared this environment with Carcharodontosaurus, a massive land-based carnivore that hunted other dinosaurs. Fossils from the Kem Kem beds show both lived in the same region, hinting at possible competition for food. 📹 Planet Dinosaur (2011)"
