Abstract

Schwartz, L.R.S. 2016. A revised faunal list and geological setting for Bullock Creek, a Camfieldian site from the Northern Territory of Australia. Memoirs of Museum Victoria 74: 263–290. The Camfield beds, in which the Bullock Creek Local Fauna occurs, is a freshwater carbonate unit deposited in a braided-meandering river environment in which abandoned channels formed oxbow lakes. Fossil quarries in the Small Hills outcrop occur in stratigraphically superposed beds. Despite this, there are no detectable changes to the fauna obtained at different levels that demonstrate a significant biochronologic time difference. Within the small mammal fauna, macropodoids are the most abundant group at Bullock Creek. Two species have been described, Balbaroo camfieldensis and Nambaroo bullockensis. A number of other macropodid taxa are also present. A diverse ‘possum’ fauna is found here, in addition to the miralinids Barguru maru and Barguru kayir, including the phalangerid Wyulda sp. cf. asherjoeli. Dasyuromorphians are also present, as are yaraloid peramelemorphians, including a species referred to Yarala.

澳大利亚北领地坎菲尔德遗址布洛克溪的修订动物名单和地质背景

施瓦茨，L.R.S. 2016。澳大利亚北领地坎菲尔德遗址布洛克溪的修订动物名单和地质背景。维多利亚博物馆回忆录74:263-290。坎菲尔德地层是一种淡水碳酸盐岩单元，它沉积在辫状蜿蜒的河流环境中，其中废弃的河道形成了牛轭湖。小山丘露头的化石采石场产于地层叠合层中。尽管如此，在不同水平上获得的动物群没有可检测到的变化，显示出显著的生物年代学时间差。在小型哺乳动物动物群中，大足类是布洛克溪最丰富的类群。已经描述了两个物种，Balbaroo camfieldensis和Nambaroo bullockensis。许多其他的巨足动物类群也存在。除了miralinids Barguru maru和Barguru kayir，这里还发现了多种“负鼠”动物群，包括指骨目Wyulda sp. cf. asherjoeli。也有准胚形动物，如yaraloid peramelmorphians，包括一种叫做Yarala的物种。
