A newly discovered dog-sized dinosaur is covered in armor and has tiny arms

Argentina has recently become home to strange dinosaur fossils. Last year, paleontologists in the country discovered dinosaur skeletons so large they thought they might have been among the largest land animals ever recorded. Now they’ve found something much smaller, and perhaps even stranger: a dinosaur the size of a dog — but covered in so much gilded armor, it’s a bit like an oversized armadillo.

Newly discovered dinosaurs given taxonomic names Jakapier Kanyukula, As paleontologists detailed in a recent article in the journal Scientific Reports. Jakapil Kanukula Lived about 97 to 94 million years ago; walked on two legs instead of four; had small arms like chicken wings; had a short beak for biting; and was equipped with a distinctive ring of armor around its neck.

“This dinosaur’s neck armor is unique in that it protects that vulnerable area from predators,” explained Sebastian Apestegia, one of the study’s co-authors. “The bones preserved from the arms told us they were small,” which is unusual for dinosaurs from this group. Jakapil Kanukula Belongs – are called thyreophorans. Thyreophorans are defined as a group of “armored” dinosaurs, characterized by thick bony armor lining their bodies. Notorious thyreophorans include Stegosaurus, which had a series of Mohawk-like spikes on its back and tail. There’s also Ankylosaurus, which resembles a giant version of the extant horned toad, albeit with a tail shaped like a mace.

discovery Jakapil Kanukula It also has scientific interest for a number of reasons. As the paper’s authors explain, the small dinosaur had some “unusual anatomical features,” including many not usually associated with beetles from that period. It is also the first identified species of beetle from Argentine Patagonia” – which is significantly southward for beetles considering the way they were previously only found in the northern hemisphere. In fact, this is known The Beetle is south of the equator.

Also, although most beetles walk on four legs, Jakapil Kanukula “It appeared to exhibit a bipedal posture,” the researchers wrote, meaning it walked on only two legs, like a human. This dinosaur is also noteworthy because its discovery in the southern hemisphere hints at a much wider distribution of beetles than previously thought. They also survived into the late Cretaceous period in South America, between 100.5 million and 66 million years ago—just before the famous extinction of the dinosaurs.

The scientific name of the dinosaur is also noteworthy because it uses an indigenous language. The word “Jakapil” is derived from the word “shield bearer” in the Argentine Puelchen or northern Tverchen indigenous languages. Likewise, the word “Kanikura” is derived from the indigenous Mapletongon language for “crest” and “stone”.

Paleontologists were also delighted to receive a surprisingly comprehensive dinosaur fossil, as they were able to find some spikes running along the animal’s back, an almost complete lower jaw, as well as its leg and arm bones as well as its neck, back and tail. vertebra.
