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
Anatomical terms of bone Anatomical terms of bone Many anatomical terms descriptive of bone are defined in anatomical terminology, and are often derived from Greek and Latin. A long bone is one that is cylindrical in shape, being longer than it is wide. However, the term describes the shape of a bone, not its size, which is relative. Long bones are found in the arms (humerus, ulna, radius) and legs (femur, tibia, fibula), as well as in the fingers (metacarpals, phalanges) and toes (metatarsals, phalanges). Long bones function as levers; they move when muscles contract. They are responsible for the body's height. A short
