Abstract

Here we report on the first mandible fragment of the giant alligatoroid eusuchian crocodyliform Deinosuchus found in Mexico. The specimen comes from Las Jicoteas locality, northwestern Coahuila. It was collected in 2007 by the first author. The fragment is from a left surangular, coming from the mandible of a Deinosuchus between six and seven metres in length.

Keywords: Deinosuchus, Alligatoroidea, Eusuchia, late Campanian, Coahuila, Mexico.
