记山东曲阜中始新世晚期─雷兽新属种

A NEW BRONTOTHERE FROM LATE MIDDLE EOCENE OF QUFU, SHANDONG

描述了产自山东曲阜黄庄动物群-雷兽新材料：周氏曲阜雷兽（新属、新种）Qufutitanzhouigen．etspnov。该材料是山东省内首次确定的需兽属种报道，它与Metatelmatherium属相似但较之进步，是已知后沼雷兽亚科（Metatelmatheriinae）在沙拉木仑期的唯一代表，与中国沙拉木仑期特有的鼻雷兽属（Rhinotitan）差别较大。

The brontothere fossil described herein was collected in 1984 by the second author from HuangZhuang Formation of Qufu, Shandong, China. Huangzhuang fauna,first reported in 1985, was regarded as Sharamuranian age, comparing to Late Uintan of North America (Sha & Wang, 1985; Shi, 1989; Tong, 1989; Wang, 1994).A few unrecognized brontothere materials have been reported from Qufu and Xintai of Shandong Province (Shi, 1989; Chow & Qi, 1982). Our specimen preserves the anterior part of a skull with almost complete upper dentition. This is the first recognizable brontothere genus from Shandong Province, and also a relatively complete material reported in China in recent years. We propose a new genus and species and refer it to subfamily Metatelmatheriinae.
