Callawayasaurus had a skull only 35 centimetres (1 foot 2 inches) long, but its whole body was about 7 to 8 metres (24 to 26 feet) long.1

Its neck contained 56 vertebrae, which is a lot, but they were shorter than the neck bones of other elasmosaurids.1

The nostrils of Callawayasaurus were long and positioned above the upper jaw bone, which had 3 to 5 teeth.1

It lived during the Early Cretaceous period, about 125 to 112 million years ago.1

The first fossils were found in the Paja Formation near Villa de Leyva, Colombia.1

A second, nearly complete skeleton was slightly more robust than the first, which might mean males and females looked a bit different.1

Callawayasaurus was named after paleontologist Jack M. Callaway, who studied ancient marine reptiles.1
