- A Deinosuchus riograndensis (Eusuchia: Alligatoroidea) from Coahuila, North Mexico Héctor E. Rivera-Sylva Eberhard Frey José Rubén Guzmán-Gutierrez Francisco Palomino-Sánchez Wolfgang Stinnesbeck Ciencias de la Tierra Mexico Eusuchia Coahuila Deinosuchus paleoecology Diagnostic remains of Deinosuchus have been discovered in the Aguja Formation (Late Cretaceous, late Campanian) near the town of La Salada (northwestern Coahuila, Mexico) and are described here for the fi rst time. The material comprises six teeth and tooth fragments that were found associated with postcranial material such as two osteoderms and a cervical and caudal vertebra and is referred here to D. riograndensis. The association with a variety of herbivorous dinosaurs and trionychid turtles suggest a predator-prey interaction, which is confi rmed by the occurrence of a vertebra with a Deinosuchus bite mark. The Deinosuchus remains from La Salada represent the southernmost occurrence of the genus known to date. 2011 artículo científico 1026-8774 https://www.redalyc.org/articulo.oa?id=57220808008 en http://www.redalyc.org/revista.oa?id=572 Revista Mexicana de Ciencias Geológicas application/pdf Universidad Nacional Autónoma de México Revista Mexicana de Ciencias Geológicas (México) Num.2 Vol.28
