Eurysternum is an extinct genus of thalassochelydian turtle.[1] Its type species is Eurysternum wagleri,[2] the holotype of which has since been lost and only survives in illustrations.[3]

Misassigned species

Eurysternum ignoratum Bram, 1965 is a junior synonym of Thalassemys hughii.[4] The Late Jurassic species Eurysternum neuquinum Fernandez and de la Fuente, 1988, described from marine deposits in Argentina, is now placed in its own genus Neusticemys.[5]
