Drepanosaurus

Drepanosaurus (Dre-pan-o-sore-us) is a genus of arboreal (tree-dwelling) reptile that lived during the Triassic Period. Drepanosaurus is a genus of Drepanosauridae, a group of diapsid reptiles known for their prehensile tails. Only one adult Drepanosaurus specimen and two immature specimens have ever been found and all lacked a head and neck. Drepanosaurus was probably an insectivore, and lived in a coastal environment in what is now modern day Italy, as well as in a streamside environment in the midwestern United States.
