A new species of Dinosaur Strange claws have been detected in Mongolia by Pelionctologist.
These new genus and species are with long claws with a therizinosor, plant-khin, two-feet veterans, and were buried in Gobi Desert, according to a new study published on Tuesday (March 25). Journal ISCIENCE,
Unlike other therizinosaur, which has three fingers on their hands equipped with long, sharp claws, this new species has only two fingers. This unique anatomy inspired its scientific name, named Donicus tsogtabariWhich is Greek for “two digits” and honors the Mongolian peliytologist Khishigajav Tsogtabatar,
“Many species of Therizinosaurus have been discovered, and this group was defined by the game of large claws by their three-clown hands,” co-author studies Darla zelenitskiA fossilist at the University of Calgary in Canada told live science in an email. “It was amazing to find a sample with only two fingers/claws because it was out of normal for this group of dinosaurs.”

Therizinosaurs is a group of dinosaurs that lived across Asia and North America during late Cretaceous period (100 million to 66 million years ago). Despite being part of the dinosaur’s theropod group – usually associated with non -vegetarian dinosaurs Tyrannosaurus Rex – Therizinosaurr was a vegetarian. These dinosaurs are known for their huge, sickle -shaped claws, with some species growing Long up to 20 inches (50 centimeters).
All other therizinosaurs that have been discovered earlier include Therizinosorus And DisinterestThey have three claw fingers on their hands, which is discovering two-banks. D. Tsogtabatari unusual.
“Therizinosaur are already some of the most unusual dinosaurs, but Donicus tsogtabari It takes it to another level, “study key author Yoshitsugu KobayashiA fossilist at the University of Hokkaido in Japan told live science in an email. “This new discovered species of Mongolia breaks the mold with just two fingers instead of typical three, offering a rare glimpse of how Theropod was developed and optimized.” “But actually makes this discovery exciting, which is incredibly well preserved on its claws- the first case in a medium- up to the big-sized Theropod Dinosaur,” Cobayashi said.

The new fossil was detected during the construction of a water pipeline at the Bayanshireee Formation in the Inmnรถgovi province of southern Mongolia. The sample excellently preserved hands, with a 3D sheath where the claw – made of keratin, would have – like our nails. Weapons, spine and parts of the hips were also preserved.
“A hallmark of the hand, therizinosaurus, this sample is excellently preserved with all finger and wrist bones,” said Zelenitsky. “Even the Cartinus sheath of the claws shows how big and sharp its claws were.”
Other species of dinosaurs, such as Tea. RexThere were two fingers, but it was first found with a therizinosor less than three digits. The study authors suggested that this species is likely to lose one of the three fingers of its ancestors.
Researchers feel that D. Tsogtabatari This may have developed this unique hand to catch better vegetation, allowing more efficient feeding.
“Loss of third finger Donicus tsogtabari Maybe it really made its remaining two fingers even better what they were designed-Labhi, “Kobayashi said.” Depending on the size of its well preserved claws and how it is curved, Donichus Probably was using his hands to grab branches and drag the flora closely, such as how chameleons do today. “” We think many therizinosaurus may have used their hands to forget ‘hook-and-pull’ speed, but Donichus It takes it to another level with the structure of its extreme claws. ,
Additionally, Kobayashi suggested that claws may have played other roles, such as “defense, courtship, or even sports.”
Researchers are thrilled with this discovery, as it not only reveals the unexpected variety within Therizinosaurus, but also marks for the fifth time that a theropod dinosaur group has developed to lose its third finger.
“While more fossils will help confirm it, all indicate signs indicate Donichus Representing a true evolutionary change, not only a flower, “Kobayashi said.” It is a remarkable discovery that rebuilds our understanding of Therizinosor and theropod development as a whole. ,
