Unprecedented discovery of mesocosy "cocosaur" in Neuquén | chronicle

A new paleontological find is the province of Neuquén as a hero, as Barrosasuchus Neuquenianus, a two-meter and 70 million-year-old crocodile who lived in the current Plaza region, will be represented in the community. huincul.

The activity will be at 10.30 am in the Cultural Center of Alberdi, located at the intersection of Alberdi and Avenida Argentina, and will be responsible for the paleontologist. Rodolfo Korias,

It all began 18 years ago, in February 2001, with a joint expedition of the Carmen Fusion Museum at Huincul Square and the Royal Museum of Paleontology of Tirel, Alberta, Canada. At that time, paleontologists carried out fieldwork in the Sierra Barossa, 30 kilometers northwest of Plaza Huinqual. So far, Barrosasuchus is Argentina's most complete peirosaurid crocodile and is a key element in studying the kinship of the group.

The expedition gathered numerous fossils of vertebrate animals, including carnivorous and herbivorous dinosaur bones, mammals, and fingerprints of birds and other small dinosaurs in the rock crests (70 million years). Among the discoveries is a nearly complete copy of the Peirosauridae crocodile.

This is the type of animal found.

After preparatory work at the Carmen Fusion Museum of Marina Alarie and several years of research, it is possible to identify a new species of crocodile called Barrosasuchus Neuquenianus.

The skeleton of the specimen, which in its life would be two meters long, is extremely nearly complete, but the tail is missing.

The etymology of the genre is happening "Maddy", with respect to Sierra Barrosa, where a pattern is found, and "Souchos" a word of Greek origin referring to Egyptian divinity with a crocodile head and which is normally used in scientific names for crocodile species. The name of the species "Neuquenianus" clearly indicates the province.

Researchers who participated in the study include Rodolfo Koriya, a member of the Neuken Culture Sub-Secretariat, Connicket, the Rio Negro National University and the Carmen Fusion Museum; Francisco Ortegafrom the Evolutionary Biology Group of the Faculty of Natural Sciences of UNED, Spain; Andrea Arcoucifrom the San Luis National University and from San Luis Zambia's connotation; and Philippe Curiefrom the University of Alberta, Edmonton, Canada.
