Abstract

Eastonian trilobite faunas of the Gordon Group in Tasmania include the new species Ceraurinella oepiki, Erratencrinurus trippi, and Pliomerina trisulcata, as well as a reedocalymeninid probably allied to Sarrabesia Hammann & Leone, 1997. Ceraurinella and Erratencrinurus have not previously been reported from Australia, the former being predominantly Laurentian but also known from NE China, the Himalaya, and Vietnam, and the latter mostly Baltic/Laurentian. Peri-Gondwanan species of Ceraurinella appear to form a clade, within which Tasmanian and Indian (central Himalayan) taxa are closest relatives.

塔斯马尼亚的上奥陶统棘虫(三叶虫)

塔斯马尼亚戈登群的东顿三叶虫动物群包括新种Ceraurinella oepiki、Erratencrinurus trippi和Pliomerina trisulata，以及一种可能与Sarrabesia Hammann & Leone(1997)有联系的reedocalymeninid。Ceraurinella和Erratencrinurus以前未在澳大利亚报道过，前者主要是Laurentian，但也在中国东北部，喜马拉雅山脉和越南已知，后者主要是波罗的海/Laurentian。Ceraurinella的近冈瓦纳种似乎形成了一个分支，其中塔斯马尼亚和印度(喜马拉雅中部)分类群是最近的亲戚。

期刊介绍： Alcheringa : An Australasian Journal of Palaeontology is the official journal of the Australasian Palaeontologists. Alcheringa covers all aspects of palaeontology and its ramifications into the earth and biological sciences, including: Taxonomy- Biostratigraphy- Micropalaeontology- Vertebrate palaeontology- Palaeobotany- Palynology- Palaeobiology- Palaeoanatomy- Palaeoecology- Biostratinomy- Biogeography- Chronobiology- Biogeochemistry- Palichnology. Review articles are welcome, and may be solicited from time to time. Thematic issues are also possible. Emphasis is placed on high quality and informative illustration, in both line drawings and photographs. Papers of general significance may receive preference over those of more local interest.
