Localizan en General Cepeda restos del primer dinosaurio Parksosaurido en el país



Como resultado de la temporada de campo de la primavera de 2014, un equipo de investigadores mexicanos y alemanes del Laboratorio de Paleontología del Museo del Desierto, el Staatliches Museum für Naturkunde Karlsruhe, la Universität Heidelberg, y el Servicio Geológico Mexicano, encontraron un nuevo afloramiento fosilífero en las cercanías de la zona de Las Águilas, municipio de General Cepeda, Coahuila, en rocas de la Formación Cerro del Pueblo, con una antigüedad de alrededor de 72 millones de años. Una investigación bajo la dirección del Dr. Héctor Rivera Sylva del material colectado, destacó la presencia de un diente y una vértebra, que por sus características fueron identificadas como evidencia de un dinosaurio de la familia Parksosauridae. El descubrimiento gana relevancia, debido a que es el primer reporte de esta familia para México.

Este grupo de dinosaurios vivió durante el Cretácico Tardío en lo que es Norte América y Asia. Fueron herbívoros, bípedos, de 2 a 4 metros de largo y es posible reconstruir el escenario en el que habitó gracias al registro fósil del Sureste de Coahuila, que cuenta con abundantes evidencias de biotopos equivalentes a pantanos y manglares, con una gran diversidad de organismos propios de estos ecosistemas.
El potencial de la investigación paleontológica continua en crecimiento ya que, con este descubrimiento, el número de familias de dinosaurios para México se eleva a 13 y se incrementa a 10 las descritas para Coahuila, lo que lo apuntala como el estado con el mayor registro de vertebrados mesozoicos continentales del país. Este patrimonio paleontológico debe resguardarse, investigarse y difundirse, puesto que en él se construye el entendimiento científico de dicha riqueza y en el proceso se derivan, tarde o temprano, numerosos beneficios sociales como la educación, cultura y turismo.
