New dinosaur bone cache found in Mexico

Thursday, March 3, 2011

The National Anthropology and History Institute (INAH) reported the discovery of a cache of dinosaur bones in the city of General Cepeda in the Coahuila desert of Northern Mexico according to a March 1, 2011, report from Fox News Latino.

The area has been well known for the large number of dinosaur footprints immortalized in the rocks there.

The bones discovered include vertebra and probable femurs or other long bones scattered at various sites in the INAH-Coahuila Center dig site that is a protected paleontological research area.

The fossils have been tentatively identified as Hadrosauridae, or duck-billed dinosaur, the Ornitomimidae, a biped similar to the ostrich, and Tyrannosaurus because the footprints of the duck-billed dinosaur, Ornitomimidae and Tyrannosaurus families have already been identified at the dig site.

The fossils could be 72 million years old (approximately the same age as the footprints) but other artifacts from the Coahuila area date from 10,000 years ago to 2.5 million years ago.

This discovery sparked new interest in the Coahuila site and plans to explore areas that are presently covered by vegetation are planned for the near future with hopes of exhuming additional fossil fragments that can be used to construct enough evidence to positively identify the ancient inhabitants of the area.

Felisa Aguilar is the paleontologist in charge of research and conservation at the INAH-Coahuila Center.
