National Institute of Anthropology and History (INAH) workers and paleontologists work on the recove … Mexico’s National Institute for Anthropology and History (INAH) has reported the discovery of the fossilized remains of a 72 million-year-old dinosaur tail in a desert in northern Mexico by a team of archaeologists and students from INAH and the National Autonomous University of Mexico (UNAM). The 5 meter (16 foot) tail is the first ever to be found in Mexico.
The INAH’s director said the dinosaur tail looks unusually well preserved, and likely made up half the dinosaur’s length. The identified fossil is believed to be a hadrosaur, or duck-billed dinosaur.
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.
