An unexpected discovery of meozozika "kokosaura" in Neuquén chronicle



A new paleontological find is the Neuquen province as the protagonist, as the crocodile Barrosasuchus Neuquenianus, a two-meter-long and more than 70 million-year-old crocodile who lived in the present Plaza region, will be introduced. Huincul.

The event will be at 10.30 pm in Alberdi's Cultural Center, at the intersection of Alberdi and Avenida Argentina, and will be in charge of paleontologists Rodolfo Coria.

It all began 18 years ago, in February 2001, with a joint expedition of Carmen Funes Museum, Plaza Huincul, and Royal Tyrrell Royal Paleontology Museum in Alberta, Canada. At that time paleontologists carried out field work in Sierra Barrosi, 30 kilometers northwest of Plaza Huincula. Barrosasuchus is the most complete peirosaurid crocodile in Argentina for the time being and is a key element for studying kinship relationships within the group.

The expedition collected a number of fossil vertebrates, including mesothelioma and hereditary bone dinosaurs, mammals and bird prints and other small dinosaurs in the upper chalk cliffs (70 million years old). Among the discoveries, an almost complete specimen of the crocodile from the Peirosauridae family stands out.

That was the look of the animal found.

After the preparations at the Carmen Funes Marina Alegría Museum and several years of research, it was possible to identify a new type of crocodile, called Barrosasuchus Neuquenianus.

The skeleton pattern, which would be two meters long in life, is exceptionally almost complete, only the tail is missing.

The genre etymology becomes "Muddy", compared to Sierra Barrosa, where the sample was found, i "Souchos" a word of Greek origin, in relation to the Egyptian deity with a crocodile head, commonly used in scientific names for crocodile species. Name of species "Neuquenianus" clearly points to the province.

Researchers who participated in the research were Rodolfo Coria, a member of the Undersecretary for Culture Neuquén, Conicet, Rio Negro National University and Carmen Funes Museum; Francisco Ortega, Evolutionary Biology Groups of the UNED Faculty of Natural Sciences and Mathematics, Spain; Andrea Arcucci, at the National University of San Luis and in the San Luis Zoology; and Philip Currie, from the University of Alberta, Edmonton, Canada.
