Abstract

Abstract Vestigial appendicular skeletons are present but have not previously been described and illustrated in the skink species Feylinia grandisquamis and Melanoseps ater. Vestigial appendicular skeletons have been described and illustrated in only one specimen of Grandidierina lineata and in a small sample of Voeltzkowia mira. Here we report a radiographic study of the appendicular skeletons of these four species. The pectoral girdle includes a vestigial clavicle in F. grandisquamis; a vestigial scapulocoracoid and sternum in M. ater; a vestigial scapulocoracoid, interclavicle and sternum, with or without a clavicle, in G. lineata; and a clavicle and scapulocoracoid in one specimen of V. mira. In all four species the pelvic girdle includes an ilium and a puboischium. No midline contact is present between the left and right puboischium, and visible forking into a distinct pubis and ischium is present only in V. mira. The only discernible limb vestiges are humeri in V. mira.

非洲和马达加斯加飞龙种的退化附属骨,Melanoseps ater, granddierina lineata和Voeltzkowia mira
退化的附属骨是存在的,但以前没有被描述和说明在石龙种Feylinia grandisquamis和Melanoseps ater。仅在一种桔梗标本和一种小样本中描述和说明了残留的附属物骨骼。在这里,我们报告了这四个物种的阑尾骨骼的放射学研究。大鳞棘鱼的胸带包括一个退化的锁骨;海蛸的一个退化的肩胛骨和胸骨;一残留的肩胛骨,锁骨间和胸骨,有或没有锁骨;在一个标本中发现了锁骨和肩胛骨。在所有四种中,骨盆带包括髂骨和耻骨。左右耻骨之间没有中线接触,只有在V. mira中才有明显的耻骨和坐骨分叉。唯一可识别的肢体痕迹是肱骨。
