It controlled essential functions such as breathing and digestion, as well as processing thought, and controlling the muscles.Īlthough the brain is small compared to the overall size of the dinosaur, the regions involved in smell, sight and hearing are well developed, suggesting this animal had keen senses. The brain is around 30 centimetres long and housed deep inside the skull. Some of the team are surprised to see that it bears no resemblance to the long, thin tongues seen in most lizards today. Inside the oral cavity (mouth), the tongue is flat and fixed to the floor of the mouth. This means they would have worked together to give Tyrannosaurus rex sharp eyesight and help it accurately judge distances – important for any predator when closing in on its prey. Reaching lengths of up to 30 centimetres, they are the longest dinosaur teeth ever found. The jaw is lined with around 60 serrated teeth. Next we remove the flesh from one side of the head, revealing the bones beneath. ![]() I caution my team – the teeth are still sharp! We manipulate the jaw and find it can still open and close. These provided the force behind one of the strongest bites in history. Peeling back the scales, we find the muscles of the jaws. This suggests Tyrannosaurus rex may have carefully handled its young. Initial observations reveal the head is covered with scales, probably sensitive to touch, like those of crocodiles today. Measuring 1.5 metres from end to end, it contains the dinosaur's sensory organs, as well as its brain and its infamous teeth. rex skull cross-section © Rachel Caldwell
