In Argentina, the fossil of a seven -meter megaraptor with a crocodile’s bone marrow -a crocodile in the jaws has been found -this is one of the most noticeable -noticeable discovery of recent years.
In South America, scientists have discovered a new type of predator dinosaur, called Joaquinraptor Casali. He reached about seven meters long, weighing more than tons and with strong claws, similar to garden scissors. This was reported by Live Science.
The debris was found in the formation of lugo kolkhui Huapi in central Patagonia, Argentina. The fossil is well preserved: scientists have found almost a whole skull, bone -but, vertebrae, front and hind feet. In the jaws of the dinosaurus, the bones of the ancient relative -child of the crocodile were to be clamp, which indicated his diet and status of the high -predator.
The study showed that the Joaquinrapor belonged to a group of megaraptors -large theropods, who lived at the end of the Cretaceous period, 70-666 million years ago. At this time, the Rex Tyranosaurus leads the northern continent, and in the south megaraptors conquered the top of the food chain.
According to scientists, the copy found is an adult and at the time of death at least 19 years. This discovery, published in the Journal Nature Communications, helps to understand the evolution of the megaraptors and their role in the Patagonia ecosystem until the extinction of dinosaurs.
Earlier it was reported that scientists discovered a new dinosaur species, which lived in the territory of modern USA about 150 million years ago.
In the UK, a new type of dinosaur with a “sail” on the back is opened
