以前未描述的材料Macrocnemus Escheranii（爬行纲，Diapsida，Prolacertiformes）增加了相当多的细节的知识，解剖学的颅后骨骼。跗骨的个体发育及其组成成分的同源性进行了讨论。爬行动物的跟骨对应于两栖动物的腓骨，而爬行动物的黄芪结合了两栖动物的中间骨和额外的骨化中心;爬行动物胫骨的存在是有争议的。Macrocnemus的跗骨包括黄芪（中间），跟骨（腓骨），中央和远端跗骨4，3和1。一个功能分析的apapericular骨骼建议主要是陆地的习惯，甚至可能是兼性两足动物在快速运动。
ABSTRACT Previously undescribed material of Macrocnemus bassanii (Reptilia, Diapsida, Prolacertiformes) adds considerable detail to the knowledge of the anatomy of the postcranial skeleton. The ontogeny of the tarsus and the homologies of its constituent elements are discussed. The reptilian calcaneum corresponds to the amphibian fibulare, while the reptilian astragalus incorporates the amphibian intermedium together with additional ossification centers; the presence of a tibiale in reptiles is controversial. The tarsus of Macrocnemus incorporates the astragalus (intermedium), calcaneum (fibulare), a centrale, and the distal tarsals 4, 3, and 1. A functional analysis of the appendicular skeleton suggests predominantly terrestrial habits, perhaps even facultative bipedalism during rapid locomotion.
