【摘要】 2013年在辽宁大连骆驼山金远洞堆积(39°23′59.01″N,121°41′20.28″E)中发现了哺乳动物残骸后,自2014年以来进行了系统发掘,出土了大量的哺乳动物化石。最近从偶蹄类化石中鉴定出较为罕见的大斑鹿(Cervus(Sika)magnus)。金远洞大斑鹿标本角柄短,角冠简单,第一枝距角环不远,眉枝与主枝的夹角较大,近于直角;上前臼齿齿冠上具明显的内中凹,上臼齿齿冠上的新棱、马刺等附属结构不存在,下前臼齿中p4臼齿化,下臼齿齿冠上的下外附尖不明显。根据目前掌握的大斑鹿化石地层资料,大斑鹿的时代分布可能是早更新世至中更新世。更多还原

【Abstract】 Since the discovery of mammalian fossils from the deposits in Jinyuandong(Jinyuan cave)(39°23′59. 01″N,121°41′20. 28″E) at Luotuoshan(Camel Hill), Fuzhouwan in Dalian Municipality, Liaoning Province in 2013, a large quantity of mammalian specimens of the Pleistocene have been discovered during the follow-up excavations.Artiodactyls, composed mainly by suids, camelids, cervids and bovids, figure the large parts of the collected specimens. A sika, Cervus(Sika) magnus(Cervidae, Artiodactyla) named by Zdansky in 1925, was identified from collected materials in recent morphological study and metric comparison with many related specimens and taxa.Its pedicle is short, antler is simple, the first tine is not far away from the burr, the angle between the first tine and the main beam is close to right angle; there is evident entoflexus on the maxillary premolars, the accessory structures such as neocrista and spur are absent from maxillary molars; the fourth mandibular premolar is molarized, ectostylid is not evident on mandibular molars. The species is quite rare and Dalian is the second area yielding Cervus(Sika)magnus after Yidu County, the type area of the species, in Shandong Province. Based on the available stratigraphic data, the geological range of Cervus(Sika) magnus is likely from the Early to Middle Pleistocene.更多还原
