About Enigmosaurus:

True to its name--Greek for "puzzle lizard"--not much is known about Enigmosaurus, scattered fossils of which have been discovered in Mongolia. This dinosaur was originally classified as a species of Segnosaurus--a bizarre, large-clawed theropod closely related to Therizinosaurus--then, on closer examination, was "promoted" to its own genus. Like other therizinosaurs, Enigmosaurus was characterized by is large claws and bizarre, "Big Bird"-like appearance, but much about its lifestyle remains, well, a puzzle.
