![]() The pubis is composed of two huge bones (left and right) that sometimes fused, with a bootlike end that hung down and forward from the pelvis. Stomachs aren't preserved, but on an animal this size, a full belly could have been holding five hundred pounds of meat. They're huge-and they had to be to hold the big ribs coming off them and a huge stomach. The back vertebrae where the ribs attach look like coffee cans. They were the attachment points for many muscles controlling the position and movement of T. These huge bows of bone (along with the neck muscles) would have protected T. pat leiggi takes a turn at preparing the vertebrae of the wankel t. rex's neck helped make its neck very flexible. The space between the large zygapophyses of adjacent vertebrae on T. ![]() They are the points at which each back vertebra is linked to the next. ![]() Pairs of big facets that rise vertically above the spinal cord on the front and back of each arch are called zygapophyses. rex and other dinosaurs is the rest of the neural arch. rex would have been useful for yanking at food.īelow the prong on each vertebra of T. What other benefit would those neck muscles have provided? Feel the back of your neck when you're biting down and pulling on a piece of taffy. The small size of the neck bones compared with the massive head they supported suggests that T. These are the attachment points for huge muscles that link up on the other end to the top of T. rex have big prongs on them, called neural spines. rex could swivel and look behind as well as ahead. But with a single condyle, a long neck,Īnd powerful neck muscles, T. rex's head was tilted forward and down when in a relaxed position. We have a double condyle (the ball fits into an axis vertebra on the other side), which limits the motion of our necks. On us it's just a little knob, but on T, rex it was the size of a small grapefruit. This adas vertebra fitted into a big ball on the back of the skull, the occipital condyle. rex's skull to the adas, or first neck vertebra. Occipital CondyleĪ special swivel joint connected T. We've humerus: the size of this arm bone suggests it was used for something, and so do its very distinctly marked muscle insertions, we thought it was pretty massive, but compared to "sue" it turns out to be rather light.Īlready mendoned a lot of the skull bones, so let's start at the back of the head and work our way down. rex skeleton that we've cleaned and that Kit Mather has illustrated. Here's a little bit of information about some of the individual bones of Kathy Wankel's T.
