Stenonychosaurus: 17 Facts You Won't Believe!

Stenonychosaurus facts on a unique lizard species.

There is a total of 700 species of dinosaurs that have been identified and named so far. Stenonychosaurus is one among the same family. They are known by their scientific name Stenonychosaurus inequalis. They belong to the genus troodon which was assigned by Phil Currie. The troodontid genus was previously associated with bird-like dinosaurs. The name troodon formosus was given to a tooth collected in Montana in 1855. Troodon was the first identified prehistoric lizard. These ideas were overturned by the '30s and '40s only to prove that the troodon was a small theropod. They were considered to be birdlike raptors and became a well-known theropod by the '80s.

Stenonychosaurus inequalis is primarily a carnivore and consumes a meat-based diet and may consume insects as well as small insects. Stenonychosaurus (Stenonychosaurus inequalis) belong to the Late Cretaceous of Alberta. Stenonychosaurus is most related to dromaeosaurus such as the Velociraptor and Deinonychus had retractable sickle-like claws on their feet. These species are in some instances listed as the most intelligent dinosaurs. Their brain was considered to be larger than the modern emu.

How did the Stenonychosaurus get its name?

Stenonychosaurus (Stenonychosaurus inequalis) was named by C.M. Sternberg in 1932 on the basis of a foot, the wreckage of a hand, a foot, and some caudal vertebrate from the Late Cretaceous of Alberta. The caudal vertebrae are the bones that make up the tails of the dinosaur. the length of the caudal vertebrae may vary from on species to another. These beings from the Late Cretaceous of Alberta were later described in more detail by D.A. Russell in 1969 which shaped the scientific foundation of a famous life-sized sculpture accompanied by its fictional, Stenonychosaurus humanoid. A complete Stenonychosaurus skeleton was described by D.A. Russell. It belongs to the genus troodon, which was assigned by Phil Currie. The genus was previously associated with bird-like dinosaurs. The name troodon formosus was given to a tooth collected in Montana in 1855. Their name stands Stenonychosaurus means narrow clawed lizard. They belong to the genus Stenonychosaurus.

How smart was the Stenonychosaurus?

Paleontologists discovered that the Stenonychosaurus has a large brain as compared to any other dinosaur since ages. In 1982, Dale A. Russell conjectured a possibility of the evolutionary path for Stenonychosaurus if had not become extinct there would evolve into intelligent beings in a paper. Troodontids had semi semi-manipulative fingers. Russell suggested that his dinosauroid would have has large eyes, three fingers on each hand. This experiment has been met with criticism from various paleontologists since 1980 when Stenonychosaurus became well known as a theropod. A model of the hypothetical human-like dinosauroid is placed at the dinosaur museum in Dorchester, England if you wish to know more Stenonychosaurus info and to visit the place if possible.
