A "narrow-clawed lizard" from Late Cretaceous period and found in southern Alberta, Canada. This creature was previously known as Polyodontosaurus. Named by U. S. fossil hunter Charles Mortram Sternberg (1885-1981) in 1932.

A dinosaur man-like model, called a Dinosauroid stands in an Ottawa museum. Some Canadian paleontologists theorize that this Stenonychosaurus could have given rise to such brainy descendants had dinosaurs endured instead of dying out.
