The Dinosaurs of Mexico: their history told by bones and teeth
Keywords:
palaeoenvironments, dinofaunas, dinosaurs, Mesozoic, MexicoAbstract
Bone and tooth records of Mexican dinosaurs have increased during recent years. However, they remain unknown for most readers. Currently numerous sites located in Baja California, Sonora, Chihuahua, Coahuila, Tamaulipas, Michoacan, Puebla and Chiapas are known and each one represents a temporal and geographical window.
The sites come from the Jurassic to the Cretaceous and they are characterized by their particular paleoenvironment and fauna. The Cañon Huizachal has one of the smaller celofisoids. Otlaltepec has a mysterious dinosaur. In Piedritas there is the shorebird Ichthyornis. In Aldama it is found the centrosaurins herds. Bonetes has the primitive hadrosaurs Huehuecanauhtlus. La Bocana Roja has the theropod Labocania and the enantiornite bird Alexornis. In El Gallo there are the large lambeosaurines Magnapaulia and some tiranosaurids. Parras Basin has the ornithomimids, the chasmosaurin Coahuilaceratops, the saurolophin Latirhinus and the lambeosaurin Velafrons. In Aguja there are the pachycephalosaurid, nodosaurids, the small centrosaurin, the chasmosaurin Agujaceratops and the titanosaurs. Sabinas Basin has the big saurolophine "Sabinosaurio". In Cuenca Cabullona there are the ornitomimid Tototlmimus, the big tiranosaurids and saurolophine like Gryposaurus. Finally, Ocozocoautla has the coast maniraptor Richardoestesia.
In the future it is necessary to continue with the findings of new localities.
