Scientists uncovered a 'shield-bearing' dinosaur that weighs as little as a cat.
that lived from the Jurassic period to the early Cretaceous period whose name means “shield bearer.” This feisty-looking group includes the bony backed, spiky tailed Stegosaurus and the tank-like Ankylosaurus. Like its prickly cousins, Jakapil had built in physical defenses, with rows of bony oval-shaped armor along its neck, back, and down to its tail.
According to lead paleontologist Sebastián Apesteguía, Jakapil marks the first-of-its-kind discovery of an armored dinosaur from the Cretaceous in South America. It also resembles a more primitive form of thyreophoran dinosaur that lived in the area significantly earlier. “Thyreophorans originated about 200 million years ago and rapidly evolved into various species distributed throughout the world,” Riguetti, first author of the work and a Conicet doctoral fellow at the Center for Biomedical, Environmental and Diagnostic Studies at Maimónides University
