Prodeinodon
Sign in to saveProdeinodon (meaning "before Deinodon") is a wastebasket taxon and a dubious genus of theropod dinosaur from the Early Cretaceous (Barremian to Aptian stages) from the Xinlong Formation in the Napai Basin of China and from the Oosh Formation of Mongolia. Two species have been formally identified (with a third informal species), all three known only from tooth fragments, showing no diagnostic features, making them difficult to classify, though they may belong to a carnosaur. At least some of the referred species may represent basal carcharodontosaurid theropods similar to Acrocanthosaurus.

Prodeinodon (meaning "before Deinodon") is a wastebasket taxon and a dubious genus of theropod dinosaur from the Early Cretaceous (Barremian to Aptian stages) from the Xinlong Formation in the Napai Basin of China and from the Oosh Formation of Mongolia. Two species have been formally identified (with a third informal species), all three known only from tooth fragments, showing no diagnostic features, making them difficult to classify, though they may belong to a carnosaur. At least some of the referred species may represent basal carcharodontosaurid theropods similar to Acrocanthosaurus.
The type species, P. mongoliensis, was described by Henry Fairfield Osborn in 1924. A second species, P. kwangshiensis, was named in 1975. "P. tibetensis" has not been formally described, and it may have belonged to its own, separate genus.
