Discovery of small armoured dinosaur in Argentina is first of its kind

Paleontologists have announced the discovery of a previously unknown small armored dinosaur in the South. ArgentinaAn animal that probably walked upright on its hind legs roamed the then-steamy landscape about 100m years ago.

Dinosaurs of the Cretaceous period, named Jakapil Kanikura, would have been well protected with a row of bony disc-shaped armor along its neck and back and up its tail, they said. It measured about 5 feet (1.5 m) long and weighed only 9–15lb (4–7kg), about the same as the average house cat.

Its fossil remains were excavated in the last decade near a dam in Patagonia in the La Buitrera paleontological zone in the Rio Negro province. Scientists have described Jakapil A study published Thursday In Journal Scientific Reports.

Scientists said Jakapil has discovered an armored dinosaur from the Cretaceous of South America. It is part of the thyriophoran dinosaur group that includes the likes of Stegosaurus, known for its bony dorsal plates and spiny tail, and the tank-like Ankylosaurus, covered in armor and wielding a club-like tail.

Lead paleontologist Sebastian Apestegia and his colleagues found a partial skeleton of Jakapil with fragments of 15 teeth, leaf-like in shape, similar to iguana teeth.

Jakapil looks like a primitive form of Thyriophoran that was very long ago, which makes it surprising that it dates from the Cretaceous. Apastegia said that such a thyriophoran had never been excavated anywhere in the Southern Hemisphere.
