A new Brazilian carnivorous dinosaur has just come out of the oven. The species, named Ypupiara lapoi, is the first record of a dromeosaurdean (or runner lizard) in the country, a group of theropod dinosaurs that includes operating system raptors, 2 of which undoubtedly the most famous is Velociraptor .
The name perform genre comes from perform tupi electronic means one who lives in the waters electronic u specific name in homage to the Alberto Lopa, which a first Brazilian paleontologist helped, Llewellyn Ivor Cost, electronic who found u materials.
The discovery was described in this Thursday’s (5) issue of It is a British magazine Documents inside Palaeontology, some of the most important insights in an area of paleontology. The work is some partnership of researchers perform National Museum, perform Rio de Janeiro, perform Amazon Museum, Government University perform ABC electronic perform Earth Science Museum, perform Geological Service perform Brazil, also perform Rio.
The fossil was found in the perform rocks site over Caiera, region over Peirpolis, near the municipality over Uberaba (MG), belonging to the Marlia formation, some of the most important studies on sedimentary rocks perform Cretceo Better (enter
electronic 72 million over years) perform pas.
The materials studied include two fragments on bones, a jaw perform with teeth (better part of a jaw) near a region perform muzzle electronic a piece of a low quality jaw. With these tiny pieces of bone, however, it was possible to identify the fossil as a dromaeosaurd when comparing it with two other species recently found in Argentina: Austroraptor cabazai electronic Buitreraptor gonzalezorum2018.
The anatomical set found zero fossil nico electronic shows that I really learned about some new species for the electronic locality, more perform than that , of the first Brazilian dromeosaurd, said Arthur Souza Brum, first author of the study of.
Thus dromeosaurds known from a way Jurssico perform from the last perform Cretceo, when, as well as operating system other non-avian dinosaurs have gone extinct. These bugs have a small to medium size, including some species up to 6 michael in length, electronic lived on all operating system continents except Antarctica, however they would have very few fossil records in South America where they form a smaller group called unenlagneos.
Like two Argentine forms have a long snout with many teeth (characteristic associated with some food based mainly on fish) electronic operating system thus teeth similar to over Ypupiara, this is some strong evidence in favor of its allocation as an unenlagneo. These animals would be closer to other dromaeosaurs found in Asia, such as some species called Halszkaraptor escuilliei, which according to the most accepted reconstructions would have a size close to a swan or an electronic goose as well. it contained many teeth in the mouth.
Zero case perform Ypupiara, its estimated size between 2 meters electronic 3 michael, the parte of a reconstitution 2 perform skull bones. In addition it performs size, the shape 2 teeth, which therefore conical electronic without serrations, therefore other unique characteristics of that pet. The region of the Marlia formation in the crettic period was wetter, with rivers, electronic probably ze similar to what is today the Pantanal. He sony ericsson would feed on fish but not exclusively on fish, it would be similar to today’s: fish, small lizards, amphibians, among other animals, says Brum.
History performs new dyno, zero however, curious minimum zero. The materials remained in the drawer of the perform collection at Museu Nacional perform Rio for almost 80 years without any guesses as to which pet it belonged to. Who collected this fossil was paleontologist Llewellyn Ivor Cost, sometime between the decades about 80 electronic 80, but he recorded it as an indeterminate vertebrate . We then started asking electronic to compare the tooth with everything we know electronic that’s how we saw that I learned it was a dromeosaurdeus, said Brum.
Zero was a mere guess that helped the determine what period the unknown pet is. At the time of Cost, there was no record of dromeosaurids in South America. It was only after 2005 that the two Argentine species that made it possible to unravel the mystery were described.
Argentina, despite going through some recent financial crisis, still has a strong investment in electronic science, mainly in paleontology. Electronic, of course, the toughest vegetation electronic the most desert climate favor the discovery of new fossils, said paleontologist Kamilla Bandeira, who is also a authors carry out study.
Although this unknown pace has remained in some drawer in the perform museum collection, The relevance of a discovery goes beyond being a first perform group record for a Brazilian territory. The type material, which is also called the holtype, was unfortunately lost in the fire that hit the National Museum in 2018. Thus, the scientific article published today remains the only perform pet record available to the community.
For Rodrigo Pgas, second author perform electronic study that conducts his research on zero National Museum doctorate, one fact about a holtipo being lost almost caused a zero job to come out. We were doing several analyzes that didn’t have time to complete. Fortunately, in quotes, we were able to photograph electronic and describe these materials, but how many were not so lucky?, he asks, his voice choked electronic operating system, his eyes watery as he remembers perform fire that left also personal marks on all operating system researchers from a institution.
The tragedy that occurred zero National Museum yet zero was fully computed, electronic u perform rescue still carried out by the electronic collection volunteers. However, it is important to note that what happened leaves an example of how the electronic operating system collections culture should be valued, explains paleontologist Lucy Souza, who also participated in the carry out study. Sony ericsson we leave it on taking care of our history, ze we do the restoration of culture each time, instead of progressing instead, we leave it on being human beings, differentiated from the other primates, on zeroing the culture.
For a paleontologist Alexander Kellner, director performs the National Electronic Museum who also collaborated on a study, an unknown whereabouts performs after a fire is undoubtedly a sad holotype event, but zero belittles a job at all. Operating system Young researchers here who are leading this work managed to get milk from a stone. European union I’m proud of them, because a beautiful work, accepted in a high-end electronic magazine with the lost materials.
The expectation on Kellner that more perform pet copies are still preserved in the locality. We need to increase operating system collection efforts in Brazil so that we will be able to get some complete picture of the richness of fossil species found in the country.
