New species of Brazilian carnivorous dinosaur honors Guarani 'carry out sex god'

A Brazil has just gained a new species of carnivorous dinosaur: u

Kurupi itaata, a medium-sized terpod (about 5 meters long). It was found near the municipality of Monte Alto, north of the state of Therefore Paulo, in the area known as Formao Marlia. described to u Brazil, distant relatives perform famous Tyranossaurus rex. the second only in the Bauru basin, which covers the region where today therefore operating system states about Therefore Paulo, Minas Gerais electronic Paran.

The fossil may represent a last 2 Brazilian dinosaurs who lived through these lands before their final zero extinction perform Cretceo, they would 66 millions over years. The rock where the

Kurupi was found has an approximate age of 66 millions of years.

The new dino was described by researchers Fabiano Iori electronic Sandra Tavares (perform Museum on Paleontology on Monte Alto – SP), Hermnio Ismael on Arajo-Jnior (from a University perform Estado perform Rio on Janeiro), Thiago Marinho (from a Government University perform Tringulo Mineiro, in Uberaba – MG) electronic Agustn Martinelli (perform Argentine Museum on Natural Sciences, in Buenos Aires). The work was published in the scientific journal Record of Sth American World Sciences.

As well as operating system other abelissaurs, one Kurupi itaata

must have very tiny arms, almost vestigial. The primary feature that differentiates the species from the other therapods found in South America is the presence of small triangle-shaped projections on the wings of these vertebrae, lateral structures that connect the vertebrae have others, possibly associated with the area of ​​connection with the musculature.

The name perform gender, kurupi, pays homage to the god of a Guaraní sexuality, while a specific eptet itaata refers to the type on rock in which u pet was found, which is very hard (stone it lasts in Tupi).

However would it be because of the power over seduction perform

Kurupi? Fabiano Iori, the first study author, explains that, as it was found near a conventional hotel in Monte Alto, the sony ericsson team referred for years to the fossil as the dino perform lodge.

It ended up getting electronic and I talked with operating system other authors, with the idea of ​​a name that would refer to it, sexuality. We ended up choosing the Guarani god of fertility and sexuality, since the territory of the Guarani extended to Paraguay, and our Argentine colleagues also knew the legend, he says.

The choice , despite having been approved by many colleagues, zero left everyone happy to perform paleontologically. Some were not amused by the relationship, he acknowledges.

But we still have the dream of finding cranial material, and as some studies show that these animals had very vascularized skulls, possibly with sexual display features, a name can take on this second meaning yet, prev.

Although it is one of the most important paleontological sites of the Cretcean period in the country, it understands the final phase (between 145 and millions of years) of the so-called Age of Dinosaurs (Mesozoic), in the Bauru basin mainly fossils were found. older, from the early Cretceo. There are few animals described for the period known as Maastrichtian, which is the end of Cretceous.

According to Iori, the

Kurupi

itaata is the result of nearly three decades of excavation work in the region. This is because, unlike the other formation that is part of the Bauru group, the Adamantina, which has already resulted in the discovery of several fossils of dinosaurs and other vertebrates in the past, including crocodylomorphs, the Marlia Formation, a little more recent, of a type of rock It is difficult to erode.

We know of the occurrence of fragmentary vertebrate material in the Marlia Formation, but they are difficult to associate even to make the formal attribution of a species. The Kurupi is the first vertebrate formally described for training, and it’s a carnivorous dinosaur, which is even cooler, he says.

The phylogenetic analysis of the fossil could not determine which would be the most closely related species precisely due to the fragmentary content of the material. Within the abelissaurdeos, however, the Kurupi itaata, even for having a more recent age, is closer to another Brazilian carnivorous dinosaur, the Pycnonemosaurus nevesi, found in rocks in the state of Mato Grosso.

Another abelisaur of great importance for the evolutionary history of the early Cretcean period where today Brazil is the tiny

Spectrovenator raged, discovered near the municipality of Corao de Jesus (MG).

We have a very complete kind of early Cretceo that the Spectrovenator, a time interval, and in Maastrichtian , we have the Pycnonemosaurus and now the

Kurupi. So, little by little, we understand electronic and understand the direction that the evolution 2 abelissaurdeos in America perform South” has taken, explains Iori.

” It is likely that these dinos were correlates of the carnotaurus from Argentina, but the vertebrae of these animals are quite distinct, he adds.

A closer analysis of the dinosaur also reveals that the bones were probably exposed for a period before to fossilize.

One of the authors performed the taphonomic analysis [mudanças que ocorrem após o processo de morte de um organismo] and saw that there is the presence of cracks indicating prolonged exposure to the elements. As there was already a suspicion that the Marlia Formation was characterized by a highly mineralized paleosol and difficult to fossilize due to the much harder nature of the rock, the new fossil corroborates this, says Iori.
