Aptychodon (meaning "unwrinkled tooth") is an extinct genus of plesiosaur from the Late Cretaceous of the Czech Republic. The type species is A. cretaceus.[1]
Discovery and naming
[edit]The holotype consists of incompletely preserved teeth and they were discovered at White Mountain near Prague, Czech Republic.[2][3] They were then sent to the Prague Museum before von Reuss (1855) described the teeth and created the species Aptychodon cretaceius.[3]
Description
[edit]The teeth of Aptychodon are conical and curved towards one side despite mostly being straight. They also measure between 2.5 centimetres (0.98 in) and 13 centimetres (5.1 in) in length.[3]
Classification
[edit]Aptychodon has been classified as a potential synonym of Polyptychodon interruptus by later authors.[1] Most authors classify Aptychodon within a basal position in Plesiosauria.
