MEXICO CITY (Reuters) - A team of paleontologists have discovered the fossilized remains of a 72 million-year-old dinosaur tail in a desert in northern Mexico, the country's National Institute for Anthropology and History (INAH) said on Monday.

Apart from being unusually well preserved, the 5 meter (16 foot) tail was the first ever found in Mexico, said Francisco Aguilar, INAH's director in the border state of Coahuila.

The team, made up of paleontologists and students from INAH and the National Autonomous University of Mexico (UNAM), identified the fossil as a hadrosaur, or duck-billed dinosaur.

The tail, found near the small town of General Cepeda, likely made up half the dinosaur's length, Aguilar said.

Paleontologists found the 50 vertebrae of the tail completely intact after spending 20 days in the desert slowly lifting a sedimentary rock covering the creature's bones.

Strewn around the tail were other fossilized bones, including one of the dinosaur's hips, INAH said.

Dinosaur tail finds are relatively rare, according to INAH. The new discovery could further understanding of the hadrosaur family and aid research on diseases that afflicted dinosaur bones, which resembled those of humans, Aguilar said.

Scientists have already determined that dinosaurs suffered from tumors and arthritis, for example.

Dinosaur remains have been found in many parts of the state of Coahuila, in addition to Mexico's other northern desert states.

"We have a very rich history of paleontology," Aguilar said.

He noted that during the Cretaceous period, which ended about 65 million years ago, much of what is now central northern Mexico was on the coast. This has enabled researchers to unearth remains of both marine and land-based dinosaurs.

The presence of the remains was reported to INAH by locals in June 2012. After initial inspections, excavation began earlier this month. The remains of the tail will be transferred to General Cepeda for cleaning and further investigation.

Why would archaeologists be digging over dinosaur bones? paleontologist are scientist who know how to uncover, classify and properly preserve the findings. I think the author of this news article may have made a mistake on reporting the proper professionals who deserve the credit.

Please, if you’re gonna post something cool at least be accurate on your reporting!
