Dalinghosaurus longidigitus
Dalinghosaurus longidigitusDalinghosaurus longidigitus was an agile, slender lizard that scurried along the shores and forest floors of Early Cretaceous lakes. Its remarkably elongated hind feet and slender toes suggest it was a swift runner, potentially capable of bipedal sprints to escape predators. Skeletons have even been found preserved inside the abdominal cavities of predatory compsognathid dinosaurs, offering direct evidence of ancient food webs.
