In the Mexican Republic, Coahuila is the territory with the most abundance of vertebrate and invertebrate fossils, both marine and continental enviroments. Most notable are dinosaur fossils of Upper Cretaceous period (70 million years ago) of Mesozoic era; represented families of Hadrosaurs, Ceratopsians, Tyrannosaurids, Ornithomimids and Dromaeosaurids, among others.
fossils are in excelent state of preservation. Coahuila is in the top
places of major fossil richness around the world. In the state of
find the Desert
Museum ( El
Museo del Desierto ) wich occupy an area of 4,5
hectares (45000 square meters; it is a very
important site of divulgation and research of the natural and cultural
of the desert, where the paleontology, geology, biology, history and
converge. This museum opened its doors on November 27,
1999 and is a nacional icon, due to the fact that it´s
the only museum that deeply investigate the subject of the
covers almost 60% of the national territory.
ON May 2001, a member of the group "Amateur Paleontologists of Sabinas" (“Paleontólogos Aficionados de Sabinas” ), found the fossil remains of this dinosaur that belongs to the hadrosaurs group commonly known as "duck bills", while he was working on industrial ground south from Sabinas, Coahuila. This is herbivorous dinosaur ( ate plants only) from the area, it age is 66 million years old and it belons to the Kritosaurid genera. They were abundant in the coahuilan territory when it had a great quantity of tropical type vegetation, which was very similar to a tropical rainforest of today. It was the most common herbivorous in the region during the Upper Cretaceous period of time.
Fossils of Kritosaur allowed for the first mounted dinosaur ever in Mexico which can be seen at the Museo del Desierto and which has been given the name of Isauria, it is a 9 meter long skeleton honouring the actress Isaura Espinoza.
OF ARRAMBERRI (Pliosaurus).
Is the representation of a marine reptile based on a young fossil specimen found by a student of the Sciences of the Earth Faculty from the Autonomous University of Nuevo León, while he was doing a geological mapping in the year 1985. There are 3 pliosaur species have been found in the south of Coahuila and in Nuevo León. The Arammerri Monster reaches 18 meters in length and lived in the open sea more than 100 kilometres from the cost 140 million years ago in the Upper Jurassic and it is considered the biggest predator of all times. They ate fishes, pliosaurus and plesiosaurus. Some pieces of a half-digested backbone that belongs to an ictiosaurus has been found in the stomach of this specimen.
Some marks, present on the fossil bones, indicate that it was fatally wounded by a much larger specimen, possibly from the same species.
