Akanthosuchus (meaning "spine crocodile," in reference to its armor) is an extinct genus of alligatoroid crocodilian, possibly an alligatorine. Its fossils are found in the Paleocene-age Nacimiento Formation of the San Juan Basin, New Mexico, USA. It is known from a partial skeleton and isolated bony armor. Its armor was distinctive, with spike-shaped and blade-shaped pieces, and it is the only known crocodilian with a combination of both.
