       Enigmosaurus was so named because when the pelvis was found the shape and form of it confused the describing palaeontologists because it was so unlike those of others.‭ ‬In actuality Enigmosaurus is a genus of therizinosaur,‭ ‬a special type of theropod dinosaur that are noted for having long necks and extra-long claws on their fingers.‭ ‬Enigmosaurus is still only known by incomplete remains,‭ ‬but these seem to represent an individual that was of a larger average for a therizinosaur.
