Its eyes, fin and body are quite beautiful, and many details are still there. The white line is quartz line. There is something in the belly of this ichthyosaur, which may be the food it ate in its lifetime. The size of the body is 53 cm. Mixosaurus was a small to medium-sized ichthyosaur, not growing more than 2 metres (6.6 ft) in total length with small species not growing more than 1 metre (3.3 ft). It possessed a long tail with a low fin, suggesting it could have been a slow swimmer, but also possessed a dorsal fin for stability in the water. The paddle-like limbs were made up of five toes each, unlike the three toes found in later Ichthyosaurs.
