Bird dinosaur species found with extremely robust hands

A new bird-like dinosaur type was discovered with unusually large and “robust” claw hands and more light was replaced to early adjustments that led to the development of birds.

Named the dinosaurs Shri Rapaxbelongs to the dinosaur group called dromaeosauridae, which includes small to medium -sized carnivores, which are considered the closest relatives of birds under dinosaurs.

The researchers found the new species based on a fossil between 75 and 72 million years, which were probably found in Mongolia in the 2000s.

However, scientists are not sure Eldonia.

“Based on the documentation associated with the sample, we temporarily refer them to Ukhaa Tolgod, Mongolia,” they wrote.

The copy probably came from the Djadokhta formation in the Gobi desert of Mongolia, which is known for its rich fossil stock, in particular from dinosaurs, which, according to scientists, dates back to around 75 to 71 million years.

“Here we describe an exquisite velociraptorin dromaeosauride from the formation of Mongolia in the upper Cretaceous period of Dschadokhta and refer to the new species Shri Rapax ”,” Researchers wrote.

Shri Rapax It was found that it has special vertebral and pelvic features together with powerful hands.

According to the study, it had a “very strong” thumb and claws that were “proportional” than in any other dromaeosauride.

The dinosaurs also had harmful adjustments, which pointed out that he supported a powerful bite.

“The most unusual feature of Shri Rapax is the extraordinary robustness of the hand, ”wrote scientist in the study published in the magazine Historical biology.

The researchers suspect that the special hands of the dinosaurs were adjustments that made it possible for him to address a larger prey such as the plant dinosaur group Ceratopsian.

“We suggest that frequent interactions with the ceratopers in combination with active anti-ratio behavior by the latter have promoted the development of robust rigid and disturbing hands under some Djadokhtan velociraptorins,” the scientists wrote in the study.

“If we accept that Shri Rapax the predatory behavior of his nearby relative informed Velociraptor MongoliensisThe more robust parts of his hands imply that it was better adjusted to address larger and more robust prey Velociraptor “,” They wrote.

The results indicate that the new species has been adapted to the handling of vertebrate bags that are larger than those of the other bird-like dinosaurs that roamed the prehistoric Jadokhtan site.

These great prey were probably also unripe people of armored dinosaurs, say scientists.
