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]
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]
