This little dinosaur could kill even the largest animals

About 70 million years ago, across the territoryhuge dinosaurs roamed modern America. Some of them were not particularly mobile and ate plants, but among them were real bloodthirsty monsters like tyrannosaurs. But did you know that the lives of ordinary animals and herbivorous dinosaurs were threatened not only by these monsters, but also by feathered predators no more than one meter tall? The remains of one of these creatures, similar to muscular ducks or geese, were found in 2008 in the US state of New Mexico. The official name was given to them only recently, when scientists found in them signs of the ability to hunt even very large animals.

Similar to muscular geese, dinosaurs could even attack large animals.

Feathered dinosaurs

Researchers already initially knew thatthe dinosaurs they found were no more than one meter tall and belonged to the genus dromaeosaurids (Dromaeosaurid). The name of the species from Greek can be translated as “lizards-runners” and it very accurately describes their mode of movement. So related to dromaeosaurids velociraptors, once upon a time lived even in the territory of the presentRussia and attacked the victims, running at fairly high speeds. It is known that the bodies of velociraptors were covered with feathers, so they are considered the closest dinosaurs to modern birds.

It was previously believed that velociraptors were covered with scales, but then it turned out that feathers

New dinosaur species discovered

A new relative of ancient velociraptors was called Dineobellator notohesperus. According to the science publication ScienceAlert, its name can be translated as “warrior navajo from the southwest. " It’s also a very due name, because these creatures, judging by the structure of their skeleton, were excellent warriors. In total, scientists unearthed about 20 bones, combining which they came to the conclusion that the new species of dinosaurs was stronger and more agile than velociraptors.

Navajo Is an Indian people living in the territoryUSA. According to data for 2015, their number was 311,000 people. The name of the dinosaur was associated with this people because its bones were found in one of their places of residence - the US state of New Mexico.

According to paleontologist Stephen Jasinski, the formthe attachment of muscles and tendons in the bones of the hands and feet indicates that the new Dineobellator notohesperus could even capture large and strong prey with its paws. The dinosaur also had a stiff tail, with which it could maintain balance during fast running and sharp turns. According to scientists, these creatures hunted for prey the way agile cheetahs hunt fast gazelles in the African savannahs today.

Cheetah hunts for a gazelle

Cheetahs are very fast and their tail is capable of beingtough and straightforward. When the runaway gazelle changes direction, the cheetah must do the same quickly. His rigid tail turns and begins to act as a counterweight and a steering wheel that help him maintain balance, the scientists explained.

The new relative of Velociraptors obviously scared manylarge animals, but he himself also had dangerous enemies. This is evidenced by traces of injuries on the bones - injuries were found on the ribs and claws of a feathered dinosaur. However, dinosaurs of this species often fought among themselves for a variety of reasons. For example, they could enter into an internecine battle for prey or trying to attract the attention of females.

Smallest dinosaur

In general, the discovery of a new species of dromaeosaurids -This is an important event in the scientific community. The fact is that their number was not particularly high. In addition, these dinosaurs had small and fairly fragile bones that could not survive to this day.

In 2019, Daria Yeletskaya wrote an article explaining why dinosaurs lost their teeth. I recommend reading it!

About finding small bonesdinosaurs are very difficult, I already spoke in one of the previous materials. It was about the smallest dinosaur, whose growth did not exceed 5 centimeters. But it is interesting that despite its rather tiny size, this creature could even attack the snakes that lived millions of years ago. Just imagine a picture - a dinosaur, the size of a hummingbird, is trying to kill and eat a huge snake. Amazing Then I recommend that you read about this ancient creation in this article.
