A sea scorpion claw from the Lower Devonian of China (Chelicerata: Eurypterida)

Wang, B. & Gai, Z.K., 2014. A sea scorpion claw from the Lower Devonian of China (Chelicerata: Eurypterida). Alcheringa 38, XX–XX. ISSN 0311–5518.

An isolated chelicera (claw) of a pterygotid eurypterid is described from the Lower Devonian Xitun Formation of Yunnan Province, China. It is different from chelicerae of other pterygotids in having four principal denticles and at least four intermediate denticles between the principal denticles on both rami. This Chinese pterygotid, estimated at about 70 cm long, was a top predator that probably hunted small, primitive fishes, such as galeaspids. This discovery represents the first record of Pterygotidae from Asia and the third fossil eurypterid from China.

科尔沁右翼中旗霍林河右岸考古调查

霍林河发源于通辽市扎鲁特旗西北大兴安岭南麓的群山之中,由西北向东南流去,经科尔泌右翼中旗流入吉林省西部的沼泽地中。河的上游经过时起时伏的丘陵山地,下游为广阔无限的草地农田,偶有沙丘散布。上世纪60年代末,笔者曾到科尔泌右翼中旗做文物调查,在霍林河右岸发现史前古文化遗址三处(图一),简介如下。图一　科尔沁右翼中旗霍林河右岸史前文化遗存位置示意图1.南佈林一号遗址　2.南佈林二号遗址3.西查干陶力盖遗址一、南佈林一号遗址南佈林位于科尔沁右翼中旗中部霍林河右岸,西北距科尔沁右翼中旗(马彦胡硕镇)约25公里,东南至高力板…     

From the modern to the archaeological: starch grains from millets and their wild relatives in China

Starch grains from 31 modern samples of millets derived from the seeds of 7 species within the genus Setaria and 2 species within the genus Panicum were analyzed to determine diagnostic morphological characteristics. Ancient starch grains recovered from a sample of broomcorn millet (Panicum miliaceum) excavated from the Cishan site (10.0-7.6 cal yr BP) in the North China Plain were then subjected to the same analyses to determine the differences in morphologies, if any, between modern and ancient samples. The data indicate that morphological features, and particularly surface and fissure features, will allow for solid identifications of ancient millet starches, while size classes will be helpful, but will not be dependable taxonomic indicators.
