Abstract
ABSTRACT Twenty-one species of small mammals are recognized from the Observation Quarry fauna including four new species: the lipotyphlans Lanthanotherium observatum (Erinaceidae), Antesorex wilsoni (Soricidae), and Scalopoides hutchisoni (Talpidae), and the rodent Mioheteromys subterior (Heteromyidae). Due to more complete material, emended diagnoses are provided for the plesiosoricid Plesiosorex greeni Martin and Lim, 2004, and cricetid rodent Copemys lindsayi Sutton and Korth, 1995. Of the 21 species recognized, seven are unique to this faunal assemblage, six are restricted to the Hemingfordian, seven are known elsewhere only from the Barstovian or later, and one is known from both the Hemingfordian and Barstovian. The small mammals suggest that the Observation Quarry contains a transitional Hemingfordian-Barstovian fauna with a greater number of species from the latter, supporting an early Barstovian age.
摘要:本文从观测石矿区系中鉴定出21种小型兽类，包括4个新种:狐尾科小兽类、狐尾科小兽类、狐尾科小兽类。由于资料较为完整，本文对蛇颈齿科动物Plesiosorex greeni Martin and Lim, 2004，以及啮齿动物criceded啮齿动物Copemys lindasayi Sutton and Korth, 1995进行了修订诊断。在已确认的21个物种中，有7个是这一动物群所特有的，6个局限于海明福特，7个只在其他地方从巴斯托夫或之后才知道，还有一个在海明福特和巴斯托夫都知道。这些小型哺乳动物表明，观察采石场包含了一个过渡时期的海明福特-巴斯托夫动物群，其中有更多的物种来自后者，支持早期的巴斯托夫时代。
期刊介绍：
Annals of Carnegie Museum is a quarterly journal that publishes peer-reviewed short and medium-length original scientific contributions in organismal biology, earth sciences, and anthropology, in 40 by 52.5 pica format (168 by 220 mm or 6-5/8 by 8-5/8 inches). Subject matter must be relevant to Carnegie Museum of Natural History scientific sections or Powdermill Nature Reserve (PNR), preferably with connection to the Carnegie collection and/or personnel.
