The giant rhino like creature, which was 22 ft long, was so formidable because
|
|
it had two four foot horns sprouting from its head which could gouge even the
|
|
largest predator.
|
|
|
|
Fossil bones of an adult animal, which weighed four to five tons and stood six
|
|
to seven feet tall at the shoulder and hip, were recovered from a site in the
|
|
state of Coahuila, southern Mexico, in 2003.
|
|
|
|
The plant-eater named Coahuilaceratops magnacuerna was an ancestor of the
|
|
famous three-horned Triceratops.
|
|
|
|
Like other horned dinosaurs, or ceratopsids, it had a large bony plate behind
|
|
its head which would have acted as a shield.
|
|
|
|
But Coahuilaceratops' most notable feature are the two enormous horns that jut
|
|
out

from above its eyes. They are the biggest horns ever uncovered.
|
|
|
|
Scientists believe the horns were most often used in mating or jousting
|
|
contests rather than to fight off predators.<
|
|
|
|
Lead researcher Dr Mark Loewen, from the Utah Museum of Natural History in
|
|
Salt Lake City, US, said: "The horned dinosaurs are an extraordinary example
|
|
of vertebrate evolution.
|
|
|
|
"They evolved and diversified ... along a thin strip of land that stretched
|
|
from Alaska to Mexico. Finding this horned dinosaur so far south in Mexico
|
|
offers us a different picture of what the ancestors of Triceratops were like."
|
|
|
|
A description of the dinosaur appears in a book, New Perspectives on Horned
|
|
Dinosaurs, published this week by Indiana University Press.
|
|
|
|
The site where the fossils were discovered, called the Cerro del Pueblo
|
|
Formation, is in an arid Mexican desert.
|
|
|
|
However 72 million years ago the region was a humid estuary with lush
|
|
vegetation.
