Clasmodosaurus
Extinct genus of dinosaurs / From Wikipedia, the free encyclopedia
Clasmodosaurus (meaning "fragmentary tooth reptile") is a genus of titanosaurian sauropod dinosaur from the Bajo Barreal Formation.[1] It lived during the Late Cretaceous in what is now Argentina. It is known only from three fossilized teeth, and is therefore a tooth taxon. It is a nomen dubium.[2][3]

The type species, Clasmodosaurus spatula, was described by Argentine paleontologist Florentino Ameghino in 1898. For a long time, these teeth were thought to belong to a theropod. The teeth of Clasmodosaurus spatula were polygonal in cross section rather than round, an unusual trait also found in the titanosaur Bonitasaura salgadoi.[4]
