Tyrannosaurus rex develops a sensitive lower jaw, a feature seen in some modern-day animals, but never seen before dinosaurs. The discovery may indicate behavior that we don’t usually associate with terrifying carnivores, such as parental care, although this has probably made them more effective killers. Dr. Soichiro Kawabe and Dr. Soki Hattori Hale Creek Formation of Fukui Prefectural University, Montana at. Rex CT scanned the bone of the lower left jaw. In Historical Biology, they report a more complex distribution of nerves than previously caught in dinosaurs, which coincide with birds such as crocodiles and ducks.
The nerves are long gone, but the canals in which they were can still be mapped. Although only the lower jaw was studied, it was assumed that the upper jaw was similarly nervous. Kawabe said in a statement, “Does this mean that T. This indicates the possibility that it was able to identify different parts of their prey and eat them differently depending on the situation.”
“It completely changed our perception of T. Rex as a dinosaur who was insensitive around his mouth … biting into anything and everything, including bones.” Previous research had suggested that the giant Tyrannosaurus Tarbosaurus chose about its prey parts, so it could be a widespread feature. T. Whether Rex kept his food for bone marrow was probably of limited interest to his prey, and probably to most dinosaur enthusiasts as well. However, the sensitive jaw may be an indication of other behaviors.
“In addition to hunting, the tips of the jaws of Tyrannosaurus were adapted for continuous behavior with fine movements, including home building, parental care, and interracial communication,” the paper concludes. This sensitivity can be beneficial in many ways as it is difficult to be sure what actually happened. Even so, owning one is still beyond the reach of the average person. At least they probably weren’t feathered.
The results were not entirely surprising, as another tyrannosaurid Daspletosaurus also appeared on more sensitive parts of the mouth than other dinosaurs studied in this way, such as Triceratops and Edmontosaurus. Even the Edmontosaurus that is more closely related to the T. rex, shows signs of a sensitive upper jaw. Many jaw-dropping spectators confidently said that the way to fight giant sharks was to punch them on the sensitive nose, although rarely reported success with this method. Presumably, if faced with the situation in Jurassic Park, someone might t. If you think this sounds silly, let’s hear your better idea.
