Its fossils have been found in places such as Montana, Colorado, Wyoming, and Oklahoma. It was discovered in Montana in 1969. Scientists think that this dinosaur had feathers. It was similar to a velociraptor in that it had a large sickle-shaped claw at the end of its feet. One difference between it and the velociraptor is size.

Its fossils have been found in places such as Oklahoma, Texas, and Arkansas. It was discovered in Oklahoma in 1940.

This dinosaur had a very high ridge of back vertebrae along the spine, from which this creature’s name is derived, meaning “high-spined lizard”. Sometimes this is shown in art as a fin or spikes on its back. It was slightly smaller than Tyrannosaurus Rex.
