First Record Of Soft-Shelled Turtles (Cryptodira, Trionychidae) From The Late Cretaceous Of Europe
Fossil soft-shelled turtles (Trionychidae) have so far been recognized in all continents except Antarctica, based largely on remains preserving their diagnostic sculptured shell bones. The origin of the group is generally assumed to be in the Early Cretaceous of Asia, whereas they first appear in No...
