报道陕西汉中梁山瓜德鲁普统与乐平统界线附近王坡页岩(斑脱岩)中的腕足动物化石4属6种:Neochonetes(Huangichonetes)substrophomenoides,Orthothetina ruber,O.regularis,O.sp.,?Martinia orbicularis,和Hustedia indica。该腕足动物群以吴家坪期暖水型腕足动物为主,既含有瓜德鲁普世孑遗分子,又具有乐平世吴家坪期新兴分子,显示了过渡类型的特点。陕南吴家坪期初期腕足动物化石群的发现,对识别瓜德鲁普世末期灭绝事件后腕足动物在吴家坪期初期的多样性和乐平世初腕足动物的复苏和辐射提供了重要的化石信息。
There are 6 species of Brachiopod fossils in Wangpo Shale (bentonites) near Guadalupe and Liangping line in Hanzhong, Shaanxi Province. They are Neochonetes (Huangichonetes) substrophomenoides, Orthothetina ruber, O.regularis and O.sp. Martinia orbicularis, and Hustedia indica. The brachiopod fauna is dominated by Wujiaping warm-water brachiopods, which contain both Guadalupt relict elements and Wupingping emerging elements in Leping stage, showing the characteristics of transitional types. The discovery of the brachiopods fossils in the early Wujiaping period of southern Shaanxi province provided important fossil information for recognizing the diversity of brachiopods in the early Wujialing period after the end-extinction of Guadalupt and the recovery and radiation of brachiopods at the beginning of the Leping epoch.
