In Depth

       Allopleuron was a large sea turtle that swam in the late‭ ‬Cretaceous seas and may have had a cosmopolitan distribution at least across the Northern Hemisphere.‭ ‬Several species have been named in the past but today some only consider the type species A.‭ ‬hofmanni as valid.‭ ‬With remains possibly being as late as the Eocene,‭ ‬it would seem that this genus of sea turtle managed to survive the KT extinction sixty-five million years ago that marked the end of many reptile genera not only including the dinosaurs and pterosaurs,‭ ‬but also other large marine reptiles like mosasaurs and plesiosaurs.
