You would not have survived this dinosaur tail stroke

Ancient team of researchers describes the discovery of a new type of armored dinosaur. The latter would have developed a tail differently than his other comrades. Its flat catapult-shaped structure was actually set laterally by seven “blades”, creating a sharp weapon.

Armored dinosaurs are known for their special tails and other characteristics for evolution. Steakosers For heavy clubs in some enclosures. Armored vehicles in southern Kondwana are very rare and intriguing, so be interested in this new invention. In review Natural, The researchers describe a Almost complete semi-joint skeleton (80%) A small armored dinosaur from the late Cretaceous found in the far south of Chile.

This “new weapon tail” reveals to us, and the remains of this dinosaur tell a hitherto unknown story in the evolution of the Ankylosers. The decay of Bangui during the Jurassic period (201.3 million to 145 million years ago), like this new species, led to the creation of radical distinctions between the northern supercontinent of Larazia and the southern supercontinent of Kondwana.

According to these analyzes, the animal may have evolved there 72 to 75 million years ago. It was also an adult model with its bones joined together. Finally, from the bird’s nose to the tip of its tail, this dinosaur measured approximately. Two meters long Eighty centimeters high and weighs about 150 kilograms.
