Researchers at the University of Tsukuba and Hokkaido have identified a new fossil of the large carcharodontosaurus carcharodontosaurus that reigned at the top of the ecosystem in the Northern Hemisphere in the late Cretaceous 90 million years ago. Published in the English scientific journal Royal Society Open Science on the 8th. It seems that the members of Tyrannosaurus, who became huge after 84 million years ago and took the “top”, were still small and overwhelmed.

Assistant Professor Kohei Tanaka of the University of Tsukuba said, “There are still untouched strata in Uzbekistan and other areas, and I would like to proceed with research and clarify the competition for carnivorous dinosaurs.”

The research team analyzed fossils found in the geological formations of the local museum about 90 million years ago.
