Template:Short description Template:Automatic taxobox
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
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
The teeth of Aptychodon are conical and curved towards one side despite mostly being straight. They also measure between Script error: No such module "convert". and Script error: No such module "convert". in length.[3]
Classification
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.
