Stenonychosaurus (meaning "narrow claw lizard") is a genus of troodontid dinosaur from the Late Cretaceous of Alberta, Canada based on a foot, fragments of a hand, and some caudal vertebrae.

A 2017 description had redeemed the validity of Stenonychosaurus and had informalised the genus "Troodon", synonymising it with Latenivenatrix.

Description

Stenonychosaurus was a small dinosaur, up to 0.9 metres (3.0 ft) in height, 2.4 metres (7.9 ft) in length,^[1] and up to 50 kilograms (110 lb) in mass.^[2]^[3]They, like most related dromaeosaurs such as Velociraptor and Deinonychus had retractable sickle-like claws on their feet.
