摘要
Megachirella wachtleri Renesto et Posenato, 2003, a well preserved partial reptile skeleton from the Middle Triassic of the Dolomites (N. Italy), was originally considered a lepidosauromorph, but no phylogenetic analysis was carried out. Consequently, the taxon was overlooked in later phylogenetic analyses of the Diapsida. Here, the holotype and only known specimen of M. wachtleri is redescribed, allowing an investigation of its phylogenetic relationships. Phylogenetic analyses confirm that Megachirella is a lepidosauromorph close to the crown group lepidosaurs (Squamata + Rhynchocephalia). Megachirella enhances our knowledge of the series of morphological modifications that led to the origin of the Lepidosauria, the most diverse clade of extant reptiles.

Megachirella wachtleri Renesto等Posenato，2003年，从多洛米蒂（N.意大利）的中三叠世一保存完好的部分爬行动物的骨骼，最初被认为是一个lepidosauromorph，但没有系统发育分析进行。因此，分类单元被忽略了Diapsida以后系统发育分析。在这里，M. wachtleri的模式标本和唯一已知的标本重新描述，允许其系统发育关系进行调查。系统发育分析确认Megachirella是lepidosauromorph接近冠集团lepidosaurs（有鳞目爬行动物）。 Megachirella增强了我们的一系列导致鳞龙超目，现存的爬行动物最多样化的类群的起源形态修改的知识。
