Scientists unearth megaraptors and fossils of feathered dinosaurs in Chilean Patagonia

Jan 16 (Reuters) – Scientists in Chile’s Patagonia area are unearthing the southernmost dinosaur fossils recorded exterior Antarctica, together with the stays of megaraptors that dominated the realm’s meals chain earlier than the mass extinction.

Fossils of megaraptors, carnivorous dinosaurs that inhabited elements of South America through the Cretaceous interval about 70 million years in the past, have been discovered as much as 10 meters lengthy, based on the Journal of South American Earth Sciences.

“We have been lacking a bit,” Marcelo Lepe, director of the Chilean Antarctic Institute (INACH), instructed Reuters. “We knew that the place there have been massive mammals, there would even be massive carnivores, however we hadn’t discovered them but.”

The stays, excavated within the Rio de las Chinas valley in excessive southern Chile within the Magallanes Basin between 2016 and 2020, additionally embrace some uncommon stays of Unenlagia, a Velociraptor-like dinosaur that most likely lived coated in feathers.

The analysis additionally sheds extra mild on the circumstances of the meteorite collision with Mexico’s Yucatan Peninsula, which can have brought on the extinction of the dinosaurs round 65 million years in the past.

INACH’s Leppe famous a pointy drop in temperature over present-day Patagonia and excessive chilly waves lasting a number of thousand years, in distinction to the extraordinarily heat local weather that prevailed throughout a lot of the Cretaceous interval.

“The large variation that we see, organic variety, can also be responding to very highly effective environmental stimuli,” Leppe stated.

“This world has already been in disaster earlier than (the meteorite) and it’s confirmed within the rocks of the Rio de las Chinas valley,” he stated.
