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] Ezcurra (2023) found Ankistrodon to be a nomen dubium, as the teeth are indistinguishable from those of Proterosuchus.
