  • How big is a T-Rex Brain

     

    The size of a T Rex brain is about 500 cc, similar to a gorilla. The popular belief is that T Rex and all the other dinosaurs had small brains and were dull. However, that is not necessarily the case. 
     
    Tyrannosaurus Rex Brain and Senses 
     
    The dinosaur had visual lobes that helped it analyze visual data coming in. Its eyes faced forward at the skull’s front, not the sides. This meant T Rex possessed depth perception. 
     
    This feature is also found in other meat eating dinosaurs. This helps the creature track down potential prey. A large portion of the brain was dedicated to processing various colors. 
     
    Anatomy 
     
    The size of a T Rex brain is hardly suggestive of the overall dimensions of the creature. An adult T Rex could be 15 to 20 feet (4.6 to 6 m) tall and 40 feet (12.4 m) long. Most of them weigh around 7 tons. 
     
    The skull was 5 feet (1.5 m) long. An examination of the remains shows the eye sockets are 4 inches (10.2 cm) long. This suggests 3 inch (7.6 cm) diameter eyeballs.
     
    The footprints are 1.55 feet (46 cm) long. The feet are actually 3.3 ft (1 m) long. The strides are 12 to 15 feet (3.7-4.6 m). Before, it was thought that T Rex could reach speeds of over 50 mph. This was how it was depicted in movies. Today, many scientists think that its top speed was 15 mph (24 km/h). 
     
    Remains of the jaws reveal that they are 4 feet (1.2 m) long. The teeth sizes varied. Some were small, but others were between 9 to 13 inches long. Broken teeth were replaced by new ones. Studies indicate its teeth could break down 230 kg (500 lbs) of bones and meat. 
     
    Tail and Skin
     
    Its tail was used as a counterbalance against its large head. The tail also helped the T Rex perform turning maneuvers. The skin was scaly and rough. Scientists also believe that the skin was bumpy. The color is still unknown. 
     
    Location and Discovery 
     
    T Rex lived during the Cretaceous Period about 80 million years ago. Most of the remains have been found in Mongolia and North America. Its most likely habitat was the forests were plant eating dinosaurs lived. Over 20 almost fully complete species have been found. Other half complete specimens have been found as well. 
     
    The size of a T Rex brain should not be used for comparison with other dinosaurs. The brains of other dinosaurs vary.
