A research group at the Institute of Dinosaur Science, Fukui Prefectural University analyzed the internal structure of the fossil bones of the lower jaw bone of the carnivorous dinosaur Tyrannosaurus in detail using a CT scan. We announced the research results that it is highly possible that we played a role like this.

A research group led by Associate Professor Soichiro Kawabe of the Institute of Dinosaur Studies, Fukui Prefectural University, used a CT scan to three-dimensionally restore the internal structure of the fossil bones of the lower jaw of Tyrannosaurus and analyzed it in detail.



As a result, it was found that the tubes through which blood vessels and nerves pass were more complicated than other dinosaurs, and that the tip of the jaw was particularly developed.



From this, it is highly possible that the lower jaw of Tyrannosaurus has a highly developed nerve and the tip of the jaw played a role like a "tactile sensor". It is possible that they could distinguish the meat and eat only the meat, or hold the child in the chin and lift it.

At the press conference, Associate Professor Kawabe said, "I think that the true appearance of Tyrannosaurus can be understood by examining the ecology of Tyrannosaurus from various aspects. I want to continue to investigate. "
