Ankistrodon

Ankistrodon is an extinct genus of archosauriform known from the Early Triassic Panchet Formation of India. First thought to be a theropod dinosaur, it was later determined to be a proterosuchid. The type species is A. indicus, described by prolific British zoologist Thomas Henry Huxley in 1865.[1] One authority in the 1970s classified Ankistrodon as a senior synonym of Proterosuchus.[2]

Not to be confused with the snake genus Agkistrodon.
