摘要根据对旧标本的研究，修订了以前的记录，并提出了爬行动物的新标识。两栖海洋形式的阿尔卑斯三叠纪和马舍尔卡克亲缘关系在中部地区被识别出来，尽管是在诱人的不完整材料上。爬行动物提供的证据表明，建筑石上部的时代为拉迪尼期早期到中期，这里阿尼西亚人和拉迪尼人之间的边界被认为位于中穆斯切尔卡尔克。
SUMMARY Previous records are revised, and new identifications of reptiles are presented, based on a study of specimensin older collections. Amphibious marine forms of Alpine Trias and Muschelkalk affinities are recognized from the Midlands, albeit on tantalizingly incomplete material. Such evidence as the reptiles provide indicates an early to mid-Ladinian age for the upper part of the Building Stones, the boundary between Anisian and Ladinian here being taken to lie within the Middle Muschelkalk.
