Omma daxishanense sp. nov., a fossil representative of an extant Australian endemic genus recorded from the Late Jurassic of China (Coleoptera: Ommatidae)

Cai, C. & Huang, D., September 2016. Omma daxishanense sp. nov., a fossil representative of an extant Australian endemic genus recorded from the Late Jurassic of China (Coleoptera: Ommatidae). Alcheringa 41, xxx–xxx. ISSN 0311-5518.

Omma Newman is an extant ommatid genus currently endemic to Australia. A new Omma species, O. daxishanense sp. nov. is described and illustrated based on a compression fossil from the Upper Jurassic Tiaojishan Formation at Daxishan, a fossil locality well known for yielding mammals, feathered dinosaurs and diverse pterosaurs. Omma daxishanense is very similar morphologically to the extant O. sagitta, but differs from the latter by its broader body and prominent temples. The new discovery documents the first valid Omma species from the Mesozoic of China and highlights the antiquity and palaeodiversity of the extant Australian endemic genus.

Barton Hill Pottery and the post-medieval redware industry in Bristol

SUMMARY: Excavation in advance of a new housing development on the site of the Barton Hill Pottery, Bristol, uncovered the full footprint of a late 19th-century pottery, a large quantity of redware wasters, and a dump of whiteware wasters from another nearby factory, which include examples of Royal Navy mess ware.     

Early history of Chinese domestic sheep indicated by ancient DNA analysis of Bronze Age individuals

China has a long history of sheep husbandry, and has several indigenous sheep breeds. However, the exact geographic origin of Chinese domestic sheep remains unclear. To provide valuable genetic information for origin of Chinese domestic sheep, we performed an ancient DNA study on 22 sheep excavated from four Bronze Age archaeological sites in Northern China. Two lineages (A and B) were observed in ancient Chinese sheep, of which lineage A was predominant reaching a frequency of 95.5%. Furthermore, phylogenetic network showed that the most frequent haplotype in ancient sheep was the founder of lineage A. These results suggest that Lineage A may hold the key to understanding the origin of Chinese domestic sheep. Sequence sharing and principal component analysis showed that the ancient Chinese sheep had a close affinity to modern Chinese sheep. However, there was no significant breed structure among three modern Chinese sheep groups, making it difficult to determine their relationship to ancient Chinese sheep. Lastly, our results imply that ancient DNA analysis could provide a new way to investigate prehistoric East-West contact.     

《稽古录》的历史兴亡论

司马光的《稽古录》共三十六条“臣光曰” ,论历史兴亡 ,概括出“人君之道有一 ,其德有三 ,其才有五”。历代帝王 ,根据才能的高下 ,可分为创业、守成、陵夷、中兴和乱亡五类。五才论重点在于论述如何守成。帝王守成的主要方面是“仁、明、武”修心三德与用人治国之道。司马光史论和政论相通。他的历史兴亡论是他政论的依据。
