Notochelone is an extinct genus of sea turtle, which existed about 100 million years ago.[1] The species was first described by Richard Lydekker in 1889.[2][3] It was the most common marine reptile living in the inlands of the sea around Queensland, Australia.[4] It was a small turtle, and was about the same size as the modern green turtle.[1] Analytical studies have indicated that the creatures frequently ate benthic molluscs.[5]
