Callawayia had more than 54 vertebrae in front of its hips, giving it a long, flexible body.1

Its front flippers had four digits, but its back flippers only had three.1

The first two neck vertebrae of Callawayia were not fused together, unlike in some other ichthyosaurs.1

A tiny bone called a pisiform was present in each foreflipper, which is unusual for ichthyosaurs.1

The humerus (upper arm bone) was short and wide with a notched front edge.1
