Mexican paleontologists say they have uncovered 50 vertebrae believed to be a full dinosaur tail in the northern desert of Coahuila state.
The National Institute of Anthropology and History says the tail is about 15 feet long and resembles that of a hadrosaur or crested duckbill dinosaur.

An institute Monday says it's not yet possible to confirm the species, but it would be the first full tail of that kind in Mexico.
Paleontologist Felisa Aguilar says they uncovered roughly half of the dinosaur, which was 36 feet (12 meters) long and is dated to have lived 72 million years ago.
Reuters reported the find of a full tail being rare in the field.
The excavation took 20 days in the municipality of General Cepeda in the northern state that borders Texas.
The paleontologists, working with Mexico's National Autonomous University, also found hip bones.

In other dinosaur-related news, last week researchers in Utah they discovered a new type of big-nosed, horned-faced dinosaur that lived about 76 million years ago in the area of what is now the Grand Staircase-Escalante National Monument.

The discovery of the creature, named "Nasutoceratops titusi," was described in the British scientific journal Proceedings of the Royal Society B and by officials at the National History Museum of Utah in Salt Lake City.
The dinosaur was a wide-bodied plant-eater that grew to 15 feet long and weighed 2 1/2 tons, said Patti Carpenter, spokeswoman for the museum. It is considered unique for its oversized nose and its exceptionally long, curved and forward-pointing horns over the eyes. It also had a low, narrow blade-like horn above the nose.
Research headed by Scott Sampson, former chief curator at the museum, determined that Nasutoceratops lived in a swampy and subtropical environment about 62 miles from the water.

It was part of the same family as the well-known Triceratops, from which it derives part of its name. The second part of the name recognizes paleontologist Alan Titus for his years of research work in the Grand Staircase-Escalante National Monument.
