abstract:Mifunesaurus (meaning "lizard from the Mifune Group (of rock formations)") is the name given to an as yet undescribed genus of dinosaur from the Late Cretaceous and is therefore a nomen nudum. It was a carnivorous theropod, probably a Tetanuran, which lived in what is now Japan during the Cenomanian stage of the early Late Cretaceous, around 95 million years ago (mya).
