A fossilized tail of a duck-billed dinosaur, or hadrosaur, is seen in the Municipality of General Cepeda, Coahuila.
A dinosaur tail that’s 72 million years old was discovered in a desert in Northern Mexico, according to the country’s National Institute for Anthropology and History (INAH). The 16-foot tail, which has 50 vertebrae, is believed to have belonged to a duck-billed dinosaur known as hadrosaur.
The team, which includes archaeologists and students, found the fossilized tail completely intact after spending 20 days slowly lifting a rock that was on top of the dinosaur’s bones. The tail most likely made up about half of the dinosaur’s length, Francisco Aguilar, INAH’s director in the northern state of Coahuila, told Reuters.
The dig took place in the small town of General Cepeda in Coahuila, which shares a border with Texas. The area is rich with fossilized discoveries. Two of the “most important paleontological sites” in the state: Las Águilas and Rincón Colorado are nine and 20 miles away, respectively.
Dinosaur tails are a rare find. This discovery could lead to a better understanding of the hadrosaur and of dinosaur diseases that resemble diseases of humans, Reuters reports.
