A staff of paleontologists found a brand new kind of dinosaur, Koleken Inakayali, a deer that lived in Patagonia 69 million years in the past. The discovery of those stays was in La Colonia, north of Chubut.
This work is a part of the National Geographic challenge, led by Diego Pol, with the participation of paleontologists related to a number of nationwide scientific establishments similar to Conicet, the Egidio Feruglio Paleontological Museum of Trelew, the Argentine Museum of Natural Sciences Bernardino Rivadavia, of Buenos Aires. , the National University of Río Negro de General Roca, and the Chinese University of Hong Kong. The research was printed within the scientific journal Cladistics.
Koleken inakayali belongs to a vital household of carnivorous dinosaurs from Gondwana, the abelisaurids, the southern hemisphere supercontinent that included what’s now South America, Africa, India and Madagascar, Australia and Antarctica. “This is an abelisaurid, the household hottest with our continent’s most well-known dinosaur, the horned carnivore Carnotaurus.“explains Diego Pol, Conicet researcher on the Bernardino Rivadavia Argentine Museum of Natural Sciences.
This new species of abelisaurid is distinguished from different carnivorous dinosaurs by different anatomical options of the cranium bones.
During the journey, a skeleton consisting of a number of cranium bones was discovered, nearly a whole set of spinal bones, a whole hip, a number of tail bones, and hind leg bones.

“Indeed, the physique of this animal was transported by the river to the port, and was buried shortly after its loss of life. We have been additionally capable of finding stays of a cranium in a part of the eroded cranium, which explains why the bones of the cranium are scattered; whereas the again a part of the skeleton, which was contained in the plaster, is nicely outlined and in a lifelike state,” commented Pol.
Doctor of Biology, Mattia Baiano, defined that the place the place it was discovered “is understood as a result of it’s the place the well-known Carnotaurus was discovered, some of the well-known dinosaurs on the planet“. It is a web site extraordinarily wealthy in fossils of all types.
“It’s at all times good to discover a new species of dinosaur as a result of it provides us an understanding of what life was like up to now. The foundation of this work is to search out out what occurred earlier than the extinction of the dinosaurs on the stage of animals and crops in Patagonia. The purpose is to search out out whether or not the variety of animals and crops was excessive or low; if there live issues which have already disappeared or if, all of the sudden, a meteorite took every thing”, defined the Italian professor from the Faculty of Geology and Paleontology of the National University of Río Negro.
This research is a part of the multidisciplinary challenge “The End of the Dinosaur Age in Patagonia”, supported by the National Geographic Society, the place More than 70 researchers and scholarship holders from Conicet participated, and colleagues from different native and international establishments.
This challenge led to a renewed paleontological expedition the place Carnotaurus was first found and now this new species. Koleken turns into the second abelisaurid to inhabit the world on the finish of the dinosaur period. “We thought they have been the most effective carnivores, not less than on this a part of the hemisphere, when the mass extinction occurred that worn out the dinosaurs from our planet. The mass extinction occurred 66 million years in the past. These could have been the final non-avian dinosaurs earlier than the mass extinction on the finish of the Mesozoic. We are speaking about 69 million years in the past,” stated Baiano.

He clarified that the findings don’t correspond to an entire dinosaur skeleton. “This time, they discovered a number of vertebrae from the again and tail, a part of the cranium, femurs, tibias, phalanges and a whole hip. Different campaigns have been carried out in numerous years to avoid wasting the whole statue,” he stated.
In addition to having distinctive options that set it aside from different dinosaurs, “Koleken has sturdy cranium bones and powerful vertebrae like different members of the identical household.“stated the researcher.
The materials was transferred and saved on the Egidio Feruglio Paleontological Museum the place specialists carried out a cautious preparation of the pattern bones. Last yr a staff of a number of paleontologists started to check them.
“We analyzed the anatomical options, we have been capable of describe the form of every bone, we found the kinship relationships and the evolutionary tales of the entire household. Koleken belongs to the Abelisauridae household, It is widespread in South America, however much more so in Argentina. There are greater than 20 species worldwide and 70% are native to Argentina“, he stated.
