Scientists have uncovered in Argentina’s Patagonian area the unfinished skeletal stays of what they consider could possibly be the oldest-known dinosaur group referred to as titanosaurs.
This group of dinosaurs, which belongs to a various group of dinosaurs known as sauropods, contains some 40 completely different species that embody a number of the world’s largest land animals to ever roam the Earth. They have been four-legged herbivores with small heads that had lengthy necks and tails.
One of many world’s oldest-known dinosaur teams
The researchers made their announcement on Monday (in Spanish), explaining the fossils they discovered belonged to a dinosaur species known as Ninjatitan zapatai — may we please take a second to acknowledge simply how unbelievable the title “Ninjatitan” is. This species was a part of the titanosaur group.
The 140-million-year-old postcranial stays of the Ninjatitan zapatai have been found within the Bajada Colorada Formation in Neuquén province in Argentina’s Patagonia area.
The workforce defined that its discovery exhibits that titanosaurs as a collective first lived sooner than was beforehand believed to be the case.
“The principle significance of Ninjatitan zapatai, past the truth that it’s a new species of titanosaur, is that it’s the earliest report worldwide for this group,” Dr. Pablo Ariel Gallina, a paleontologist on the Fundación Azara in Maimonides College and CONICET, said in Sci-News.
“This discovery can be essential for the data of the evolutionary history of sauropods, as a result of the fossil data of the Early Cretaceous epoch, in round 140 million years in the past, are actually very scarce all through the world,” he continued.
Ninjatitans have been massive dinosaurs, spanning roughly 65 ft (20 meters), however they weren’t the most important titanosaurs on the market. Some, like the large Argentinosaurus, may go as much as 115 ft (35 meters).
The workforce additionally highlighted the truth that its discovery in Patagonia strongly factors in direction of the concept that titanosaurs originated within the southern hemisphere.
