Falcarius utahensis

Falcarius was a primitive therizinosaur from the Early Cretaceous of Utah. While later therizinosaurs would become pot-bellied plant-eaters, Falcarius captures an early, omnivorous stage in the shift from meat-eating toward plant-eating. Falcarius combined a long neck and leaf-shaped teeth with still-sharp raptorial claws, and presumably hunted small vertebrates and invertebrates, while also selecting nutrient-dense portions of plants to consume.
