Tyrannosaurus Rex had neural sensors in its teeth to recognize prey

The nerve system of T. rex was more advanced than that of other dinosaurs and was similar to that of the dinosaurs.

modern crocodiles and some birds. Scientists noted that this system helped to effectively catch and eat prey. 

Scientists from the Institute for Dinosaur Research at the University of Fukui Prefecture in Japan, during a new study, studied the internal structure of the mandible of a Tyrannosaurus rex.

Scientists used computed tomography to analyze and reconstruct the neurovascular canal. They then compared the resulting model with other extinct and living species.

The present study shows the presence of neurovascular channels with complex branching in the lower jaw of Tyrannosaurus rex, especially in the anterior region of the tooth, and it is more likely that a similar complex branched neurovascular canal was also present in its upper jaw.

The authors hypothesized that the trigeminal nervous system in Tyrannosaurus rex worked like a sensitive sensor in the snout: it could recognize sizeBased on this information, the dinosaur could change its hunting strategy.
