Carnosaur

Anatomy

Carnosaurs share certain distinctive features, one of which is a triangular-shaped pubic boot. They also have 3 fingers per hand, with the second and third digit being approximately equal in length. The femur is larger than the tibia. Another defining feature of carnosaurs is that the chevron bases on their tails have anterior and posterior bone growth. The largest carnosaurs can reach up to 10 meters in length. The length of the body from the tail to the hip is between 54% and 62% of the total body length, and the length of the body from the head to the hip is between 38% and 46% of the total body length. Carnosaurs scaled their limbs relative to their body in a way similar to how other large theropods, like the tyrannosaurids, did. During the Cretaceous, some carnosaurs grew to sizes similar to those of the largest tyrannosaurids. These large carnosaurs lived in the same time period as the other large theropods found in the upper Morrison and Tendaguru formations.
