Hadrosaur Tail from Mexico

Published: 1st Aug 2013

The fossilised tail of a duck-billed dinosaur from about 72 million years ago has been discovered in Mexico. The hadrosaur tail is nearly 5 metres long and is composed of 50 articulated vertebrae. It was found in the northern state of Coahuila along with some other bones, such as a hip, from the dinosaur.

Early study of the tail, which would have composed about half the length of the complete dinosaur show signs of disease. The dinosaur suffered from a tumor and from arthritis.
