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
Vancleavea parts of the hand. The second metacarpal is longer, and the third and fourth are tied for the longest bones of the hand. Unguals (claws) have not been found, and the rounded ends of certain phalanges indicates that "Vancleavea" likely did not possess them. As with other reptiles, each hip of "Vancleavea" is formed by three plate-like bones: the illium (above the hip socket), the pubis (in front of the hip socket), and the ischium (behind the hip socket). The illium of "Vancleavea" is particularly unusual. Most archosauriforms have illia which are somewhat low, directed from front to back (anteroposteriorly).
