A new study published recently in “Historical Biology” reveals that Tyrannosaurus rex has a “complex neurovascular system”, including teeth in Inside, the tip of their chin can be used as a “sensitive tactile sensor.” This complex feature may give Tyrannosaurus a unique ability among its kind to distinguish different elements from food.

Analysis of Tyrannosaurus rex jaw teeth revealed a complex neural pattern similar to “tactile foraging birds” and existing crocodiles. According to this research, evidence shows that its complexity exceeds that of other dinosaurs that have been analyzed.

The study involved the lower jaw of Tyrannosaurus rex, but the researchers pointed out that the upper jaw may also have a similar degree of complexity. Based on these findings, the study suggests that these dinosaurs may use their jaws and noses for many things, including identifying the more nutritious parts of their prey while feeding.

The tip of the chin may be sensitive enough, for example, to distinguish the difference between bone and meat when eating. Although there are strong enough teeth to crush bones, past research has found evidence that these dinosaurs have enough insight to carefully gnaw off the bones without crushing the bones.
