Segisaurus

Segisaurus (meaning "Tsegi Canyon lizard") is a genus of small coelophysidtheropoddinosaur, 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.
