Dinosauroid

Hypothetical species and thought experiment

The dinosauroid is a hypothetical species created by Dale A. Russell in 1982. Russell theorized that if a dinosaur such as Stenonychosaurus had not perished in the Cretaceous–Paleogene extinction event, its descendants might have evolved to fill the same ecological niche as humans. While the theory has been met with criticism from other scientists, the dinosauroid has been featured widely in books and documentaries since the theory's inception.
