Scientists have discovered a new dinosaur from Argentina with strong claws, feeding on the old crocodile bone.

The new discovery may have been 23 feet and was praised by a mysterious group of dinosaurs called Megaraptorans. They wandered through what is now South America, Australia and parts of Asia, and they were divided into different types over millions of years.

“Megaraptorans was famous for their extended skulls and” very huge and strong claws. “

But it was not yet clear how these creatures were hunted and where they were falling on the evolutionary timetable – mainly because the excavations that have been recovered so far were incomplete.

“Megaraptorans is among the least understood dinosaurs”, IBIRICU Reuters news news agency.

In a new study, the researchers said they discovered part of a skull in addition to the arm, leg and tail bones from the formation of Lago Kaloi Huabi’s rocks in Patagonia. Notice unique features in the bones that made them realize that this could be a new type.

“This is the last member of the Megaraptornian clan called Joaquinraptor Casali,” said Federico. Posted on Tuesday In Nature Communications.

The creature is likely to live between 66 and 70 million years – near the time that the dinosaurs became extinct – at least 19 years old when he died, although scientists do not know what he killed.

The anterior stem bone can lead against its jaws – which belongs to close to the old crocodiles –

Matt Lamana, the study author, told Reuters that unlike T

“This indicates that these two predators models have evolved various amendments to accomplishing the same main thing – that is, to capture, get up, kill, and eat other animals such as other dinosaurs,” Lamana told Reuters. “In particular, why these groups have evolved along these different evolutionary paths are still a mystery, but it indicates that during the Cretaceous era, there was more than one way to be a large predator.”

Embriko is the new dinosaur on the memory of his son Jawakin. While Joaquin was very small and has not yet developed the magic of dinosaurs, IBiricu still believed that he would have been able to name one name.

“All children love dinosaurs, so he may also be a fan,” he said.

This discovery comes a few months after the scholars were identified to Khancoloogulinsis, a new predecessor T. Rex, whom the researchers called “Lost link” Between Apix predators.
