A team of archaeologists have discovered the fossilised remains of a 72 million-year-old dinosaur tail in a desert in northern Mexico, it has been announced.

The ‘unusually well-preserved’ five yard-long tail was the first ever found in Mexico, said Francisco Aguilar, director of the country’s National Insтιтute for Anthropology and History.

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

The tail, found near the small town of General Cepeda found in the border state of Coahuila, likely made up half the dinosaur’s length, Aguilar said.

Archaeologists 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 fossilised bones, including one of the dinosaur’s hips, INAH said.
