       Callawayasaurus was originally known as a species of Alzadasaurus until Kenneth Carpenter studied the remains and found that they actually represented a new genus.‭ ‬On a related note the type specimen of Alzadasaurus today only exists as a synonym to Thalassomedon and Styxosaurus.‭ ‬Carpenter named the new genus in honour of fellow palaeontologist Jack M.‭ ‬Callaway who is noted for his work on marine reptiles.‭ ‬The species name C.‭ ‬colombiensis means‭ ‘‬from Colombia‭’‬.
       Callawayasaurus is particularly noted for its fifty-six cervical‭ (‬neck‭) ‬vertebrae that are quite short when compared to other elasmosaurid plesiosaurs.‭ ‬Also,‭ ‬Callawayasaurus has no pectoral bars,‭ ‬a feature shared with the elasmosaurid Terminonatator which lived during the late Cretaceous.
