They find giant nails in the Kobe Desert of a species that has never been seen before

In the desert of Kobe, southeast MongoliaSome have found some Huge nails It resembles the feathers with a species that is not known yet. Thanks to the extraordinary state of the localized fossil model, researchers were able to find out how these nails would have been millions of years ago.

A group of Hokkaido University (Japan), led by Paleonologist Yoshitsuku Gopayashi In a recent study The details of the invention of this species were baptized Tonichus chocutterIt combines the time “Nails of the nails” In the Greek language and in the name of the Pelonologist Mangol Kishikjov Choctpatter.

The area where the fossil was located in 2012 was the main center of the fossils Tinosars and giant footprints Thanks to the dry conditions of the terrain and its soil, clay and sand lithifity layers.

Researchers have been able to date the age of this fossil, which is believed to be 90 to 95 million yearsAnd above all, their impressive nails highlights nearly 30 centimeters long and their still visible keratin envelopes.

He Tunicus This is a part of the Terisinosars, which is a group Bedic and feathers dinosaurs They are found in fossil deposits of Cretessius in Asia and North America Alarm. However, there are two of them, unlike their other relatives defined by having three fingers on each nails.

“Most thermopodes, including other Terisinosoriaos, retained Three operating fingersSo find someone who has lost one This is the most unexpected“Gopayashi said in the middle of The new scientist.

As researchers, imposing curves and their 90 -degree operating limit claim that this dinosaur He caught the plants In a similar way to the current lazy or chameleons. The article points out in the article that “the evolution of their unusual hands may have played an important role in the cload of the Clade’s food ecology, as” long and small leaf -shaped teeth or almighty theropods. “

“Although the nails usually have a dominant operation, probably Food search With hooks and drawers in obtained Terisinosoros, these structures may have been Used for other purposesDescribe regionalism, security, court, sports, etc “.

In this case, the invention has more value because they are The big dinosaur’s triangular nails They were able to keep the bones of the pod and the base finger. Gopayashi concludes, “Keratin is usually not fossil. This is scattered before the bones.”
