With their sickle claws and agile movements, raptors were undoubtedly one of the most ferocious dinosaurs when they roamed the Earth.

Now scientists have discovered the remains of a new species of megaraptor that measured 33 feet long and weighed five tons, which stalked the forests of Argentina 70 million years ago.

Researchers from the National Council for Scientific and Technical Research have named the new species Maip macrothorax and believe it to be the largest megaraptor found to date.

Maip macrothorax: Meet the megaraptor

Length: 30-33 feet (9-10 meters)

Mass: 5 tons

Movements: Can stand and walk or run on hind legs

Claws: 13.7 inches long

Location: El Calafate, 2,677 miles from Buenos Aires

Chronology: 70 million years ago

The bones of the megaraptor were discovered in El Calafate, 2,677 km from Buenos Aires, a few days before the outbreak of the global pandemic.

“With Maip, we defeated the pandemic,” said Fernando Novas, leader of the team that collected the bones.

An analysis of the bones revealed that Maip was probably 30 to 33 feet (9 to 10 meters) long and weighed about five tons, about twice as heavy as a rhinoceros.

His spine was made up of huge vertebrae, connected by a system of muscles, tendons and ligaments, according to the team.

This allowed the huge dinosaur to stand on its hind legs while walking or running.

“Maip’s bones have helped us better understand the anatomy of megaraptors,” said Mauro Aranciaga Rolando, first author of the study.

“They belong to a family whose skeleton was not like that of a tyrannosaur, large but heavy animals, but rather light.

Maip also had a long tail and legs, as well as huge claws measuring 13.7 inches long, which would have served as her primary weapon.

“In other words, their bones were not strong, but rather had a large number of internal voids which made them much lighter, something like a hollow brick compared to a solid one.”

The first megaraptor was discovered in 1996 in Neuquén, Argentina, with later finds in Australia, Japan and Thailand.

“When I had the chance to discover the first megaraptor in Neuquén, it was a great shock because it was a huge carnivore that had hands with claws about forty centimeters long, unheard of,” said said Mr. Novas.

“Smaller relatives of this species were later discovered in Australia. Then also in other regions of Patagonia, and the family of these dangerous predators grew.

“These findings are complemented by Maip: we now have one of the largest, hardiest and one of the last living in the region before the mass extinction at the end of the Cretaceous.”

El Calafate, the area where Maip was found, would have looked very different 70 million years ago, according to the team.

“It was a warm ecosystem,” Mr. Novas explained.

“There were aquatic and terrestrial snails, plants of very different affiliations, it was a forest, almost a jungle, with puddles, lakes, streams and various creatures such as frogs, turtles, fish , small birds and mammals.

“The Andes had not yet risen. Of all these organisms that lived at the time, we collect fossil remains, and now, with Maip, we have added a super predator, which allows us to complete the food pyramid.

While the discovery of Maip’s skeleton helps shed light on the life of megaraptors, several questions remain unanswered.

“Megaraptors are quite enigmatic predators, and although Maip has helped us solve several issues, in particular their related relationships with other carnivorous dinosaurs, aspects of their hunting behavior still remain to be elucidated, for example what would have been their favorite prey, among other things,” Rolando added.

The team now plans to revisit the site, hoping to collect more data on the megaraptors.

KILLING THE DINOSAURS: HOW A CITY-SIZED ATEROID ELIMINATED 75% OF ALL ANIMAL AND PLANT SPECIES

About 66 million years ago, non-avian dinosaurs were wiped out and more than half of the world’s species were wiped out.

This massive extinction paved the way for the rise of mammals and the appearance of man.

The Chicxulub asteroid is often cited as a potential cause of the Cretaceous-Paleogene extinction event.

The asteroid slammed into a shallow sea in what is now the Gulf of Mexico.

The collision released a massive cloud of dust and soot that triggered global climate change, wiping out 75% of all animal and plant species.

The researchers say the soot needed for such a global catastrophe could only come from a direct impact on rocks in the shallow waters around Mexico, which are particularly rich in hydrocarbons.

Within 10 hours of impact, a massive tsunami swept across the Gulf Coast, experts said.

This caused earthquakes and landslides in areas as far away as Argentina.

Investigating the event, researchers found small particles of rock and other debris that were thrown into the air when the asteroid crashed.

Called spherules, these small particles covered the planet with a thick layer of soot.

Experts explain that the loss of sunlight caused a complete collapse of the aquatic system.

In effect, the phytoplankton base of almost all aquatic food chains would have been eliminated.

It is believed that the more than 180 million years of evolution that brought the world to the Cretaceous were destroyed in less than the lifespan of a Tyrannosaurus rex, which is around 20 to 30 years.
