Anquilosaurios de Coahuila, México
Contenido principal del artículo
Resumen
El registro fósil de Ankylosauria está bien documentado en varias regiones del mundo, pero sigue siendo relativamente escaso en México. En este trabajo reportamos nuevo material de tireóforos del Cretácico Tardío en Coahuila, noreste de México. Los especímenes, que incluyen osteodermos aislados y elementos esqueléticos parciales, contribuyen a nuestra comprensión de la diversidad, paleobiogeografía y paleoecología de este clado de dinosaurios en América del Norte. Las comparaciones morfológicas sugieren afinidades con anquilosaurios nodosáuridos, ampliando su rango conocido y sus roles ecológicos en la región. Este descubrimiento resalta la importancia de Coahuila como una localidad clave para el estudio de faunas de dinosaurios en el margen sur del Mar Interior Occidental.
