Archaeologists discover dinosaur tail in Mexico's desert

Archaeologists in Mexico have unearthed the fossilized remains of a 72 million-year-old dinosaur tail, the country's National Institute for Anthropology and History (INAH) said.

The five-metre tail was the first ever found in Mexico and was unusually well-preserved, said the INAH's director Francisco Aguilar.

The team of experts, made up of archaeologists and students from INAH and the National Autonomous University of Mexico (UNAM), said the tail belonged to a hadrosaur, or duck-billed dinosaur.
