Segisaurus meaning “Segi canyon lizard” or Segisaurus halli is a genus of small coelophysoid theropod dinosaur, that measured approximately 1 metre (3.3 feet) in length. The only known specimen was discovered in early Jurassic strata in Tsegi Canyon, Arizona, for which it was named. Segisaurus is the only dinosaur to have ever been excavated from the area.

Segisaurus lived about 183 million years ago during the Jurassic period. It was a primitive bipedal theropod roughly around the size of a goose. Segisaurus was 3.3 feet long, 1.65 feet tall and weighed about 4 to 7 kilograms.

It was nimble and insectivorous, although it may have scavenged meat also. It was bird-like in structure, with a flexible, elongated neck and stout body. Segisaurus was three-toed and had powerful legs that were long compared to its body length. Like its legs, Segisaurus had a long tail and long forearms.

Its collar bone was not unlike a bird’s, thus strengthening scientists’ arguments that dinosaurs were related to avians. Segisaurus is described from the only specimen ever found, the holotype UCMP 32101, which was a sub-adult.

The full size of Segisaurus as an adult may never be known. Strangely, clavicles were found on the Segisaurus specimen, which were unknown in other dinosaurs from that era.

A speculative interpretation by Charles Lewis Camp was that the “splint-like” neck ribs supported a Draco-like patagium along the neck, to improve the animal’s ability to move quickly. Segisaurus is significant because it demonstrates that the clavicle was primitively present in early theropods.
