Paleontologists in Argentina have discovered the fossilized remains of a hitherto unknown type of armored dinosaur, and the interesting fact is that this representative is the so-called. thyrophorus walked the Earth during the Cretaceous.
The dinosaur was named Jakapil kaniukura and according to some characteristics, it seems as if it is a primitive relative of ankylosaurus and stegosaurus, however, researchers claim that only after detailed analyzes will they be able to answer whether it may be a representative of a completely new genus.
After analyzing the skeleton, paleontologists from the Félix de Azara Natural History Foundation in Argentina confirmed that J. kaniukura had a series of spines that stretched from the neck to the tail, which most likely had a protective role because they could grow up to 1.5 meters . As well as that its similarity with the stegosaurus is reflected in its teeth – which had the shape of a leaf – with the help of which it ate plants. It was also established that he walked upright on our planet in the period from 97 to 94 million years ago.
A discovery that changes paleontology textbooks?
A partial skeleton of a dinosaur was discovered in the province of Rio Negro in northern Patagonia, a place known for frequent finds of stegosaurus, ankylosaurus and similar so-called. armored dinosaurs from the Thyreophora group.
However, the earliest fossil remains of members of this group mostly come from the Jurassic period, which lasted from about 201 million years to 163 million years ago. Which is why the researchers’ opinion is that the discovery of J. kaniukura indicates that early thyreophores had a much wider geographical distribution than previously thought.
Also, an interesting fact is that until now scientists assumed that thyrophorans in South America died out by the Middle Jurassic period – 174.1 to 163.5 million years ago, but now it is more than obvious that they survived until the Cretaceous.
The discovery was published in the journal Scientific Reports, and the student of pelontology, Gabriel Diaz Hantena, went a step further and, based on all the information collected, reconstructed its appearance and “revived” the ancient creature with the help of computer animation.
