Eupodophis years old. It was found in Cenomanian-age limestone near the al-Nammoura village in Lebanon. "Eupodophis" was a marine snake that lived in the Mediterranean Tethys Ocean. It had a laterally compressed body and short, paddle-like tail. The vertebrae and ribs of "Eupodophis" are pachyostotic, or thickened, as an adaptation to a marine lifestyle. The pelvic bones are small and weakly attached to each other. Tarsal bones are present but reduced in size and form. The metatarsals and phalanges of the foot are absent. The fossil skeleton of "Eupodophis" was analyzed using synchrotron x-rays at the European Synchrotron Radiation Facility in
Skeletal system of the horse Skeletal system of the horse The skeletal system of the horse has three major functions in the body. It protects vital organs, provides framework, and supports soft parts of the body. Horses typically have 205 bones. The pelvic limb typically contains 19 bones, while the thoracic limb contains 20 bones. Bones serve three major functions in the skeletal system; they act as levers, they store minerals, and they are the site of red blood cell formation. Bones can be classified into five categories Ligaments and tendons hold the skeletal system together. Ligaments hold bones to bones and tendons hold bones
