The last swimmer

Un elasmosaurio de finales del Cretácico, el más joven hasta la fecha. Quizás fuese uno de los últimos plesiosaurios que nadaron en los mares someros de lo que hoy es Canadá.

Terminonatator (meaning "last swimmer") is a genus of elasmosaurid plesiosaur from the Late Cretaceous of Saskatchewan, Canada. It is known from a skull and partial skeleton from a young adult, found in the Campanian-age Bearpaw Formation near Notukeu Creek in Ponteix. Terminonatator is currently one of the youngest plesiosaurs from the Western Interior Seaway.
