Mixosaurus cornalianus, Ichthyosaurs Baryonyx Lepidotes inhabited both freshwater lakesMixosaurus is an extinct genus of ichthyosaur. Fossils of Mixosaurus have been found all over the world China, Timor, Indonesia, Italy, Spitsbergen, Svalbard, Canada, Alaska, and Nevada. It was named in 1887 by George H. Baur. The name means "Mixed Lizard", and was chosen because it appears to have been a transitional form between the eel shaped ichthyosaurs such as Cymbospondylus and the later dolphin shaped ichthyosaurs, such as Ichthyosaurus.
