Scientists unearth megaraptors, feathered dinosaur fossils in Chile’s Patagonia

19

Scientists in Chile’s Patagonia space are unearthing the southernmost dinosaur fossils recorded exterior Antarctica, along with stays of megaraptors which may have dominated the realm’s meals chain sooner than their mass extinction.

Fossils of megaraptors, a carnivorous dinosaur that inhabited elements of South America in the course of the Cretaceous interval some 70 million years in the previous, had been current in sizes as a lot as 10 meters prolonged, primarily based on the Journal of South American Earth Sciences.

“We were missing a piece,” Marcelo Leppe, director of the Chilean Antarctic Institute (INACH), suggested Reuters. “We knew where there were large mammals, there would also be large carnivores, but we hadn’t found them yet.”

The stays, recovered from Chile’s far south Rio de las Chinas Valley inside the Magallanes Basin between 2016 and 2020, moreover embrace some unusual stays of unenlagia, velociraptor-like dinosaurs which probably lived coated in feathers.

The specimens, primarily based on University of Chile researcher Jared Amudeo, had some traits not present in Argentine or Brazilian counterparts.

“It could be a new species, which is very likely, or belong to another family of dinosaurs that are closely related,” he acknowledged, together with additional conclusive proof is required.

The analysis moreover shed additional light on the circumstances of the meteorite impression on Mexico’s Yucatan Peninsula which can have triggered the dinosaurs’ extinction some 65 million years in the previous.

INACH’s Leppe pointed to a sharp drop in temperatures over present-day Patagonia and waves of intense chilly lasting as a lot as quite a lot of thousand years, in distinction to the terribly warmth native climate that prevailed for lots of the Cretaceous interval.

“The enormous variation we are seeing, the biological diversity, was also responding to very powerful environmental stimuli,” Leppe acknowledged.

“This world was already in crisis before (the meteorite) and this is evidenced in the rocks of the Rio de las Chinas Valley,” he acknowledged.
