Euclastes is an extinct genus of sea turtles that survived the Cretaceous–Paleogene mass extinction. The genus was first named by Edward Drinker Cope in 1867, and contains three species. E. hutchisoni, was named in 2003 but has since been reassigned to the genus Pacifichelys,[3] while E. coahuilaensis named in 2009 was reassigned as Mexichelys coahuilaensis in 2010.[4][5]
