The calcareous nannofossils place the strata within the temperate-latitude CC8a Subzone and the Southern Ocean Sollasites falklandensis Subzone; the planktonic foraminifera indicate that the beds belong to the Hedbergella planispira Zone of the Australian region. The biozones suggest an early Albian age (later than the earliest Albian). Abundant calcareous and siliceous plankton and the Marssonella Association of benthonic foraminifera indicate normal-marine depositional conditions in a water depth of about 100 m. The transition from Windalia Radiolarite to Gearle Siltstone may reflect a marine transgressive pulse that reactivated bottom-water circulation and facilitated a significant increase in the calcareous biogenic component of the sediment.

In addition, new but fragmentary brachyopoid material from the Arcadia and overlying Glenidal Formations provides information on derived character states within the superfamily. Controversy surrounds the correct familial composition of the superfamily Brachyopoidea, with the family Brachyopidae being allied by various authors with a diversity of other Triassic and Permian families.

Lisogorites is an aberrant asaphid, and is considered to be a senior synonym of Trigonoaspis and Tangyaia. Ampyxinella is regarded as referable to the subfamily Endymioninae. The raphiophorid Taklamakania has only three thoracic segments and may have been derived from Ampyxina by neoteny. The morphological and taphonomical features of the trilobites suggest that this faunule lived on a soft muddy substrate in a quiet, deeper-water, slope environment of the ‘Raphiophorid Biofacies’. Palaeogeographically the Kalpin area was located on the northwestern slopes of the Tarim carbonate platform during Caradoc times. Closest zoogeographic relationships of this fauna are with South China, Kazakhstan, North China and eastern Australia.","PeriodicalId":50830,"journal":{"name":"Alcheringa","volume":"19 1","pages":"47-72"},"PeriodicalIF":1.3,"publicationDate":"1995-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/03115519508619098","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59985056","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
