Haasiophis to that possessed by "Pachyrhachis". Both femurs are preserved with the specimen, but the rest of the right leg is missing. The left zeugopodium, tarsus, tibia, and fibula are preserved though the tibia is disarticulated slightly. The foot is composed of three tarsal ossifications and five metatarsals. The tarsal ossifications do not show signs that the bones were connected to each other during life. Traces of two phalanges are discernible behind metatarsals two and three. Several of the skeletal characters of "Haasiophis" may be interpreted as indication of "Haasiophis" being a juvenile specimen of "Pachyrhachis". The small overall size, underdevelopment
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
