In 2014 and 2015, the Research Center for Chinese Frontier Archaeology at Jilin University and the Jilin Province Archaeological Research Institute jointly conducted two excavations at the Yinjiawopu Site, in Da’an City, Jilin Province, Northeast China. One burial, two canals, five leaching pits, two house-foundations, four hearths, 103 pits, two ditches, and over 800 pieces of artifacts dated from the 12th to the 13th centuries a.d. (the Liao-Jin period) were found. Analysis shows that these features belong to a salt production workshop. This study marks the first discovery of a salt production site in Northeast China. The archaeological, ethnographic, and historical materials from the site allow a reconstruction of the chaîne opératoire of salt-making by the inhabitants of the Northeast China Plain during this period. This study sheds light on the exchange and control of salt, on the activities and daily life of the inhabitants of the region, and on their relationship with the environment. 相似文献
Cai, C., Liu Y. & Huang, D., February 2017. A new species of Loricera Latreille from Eocene Baltic amber (Coleoptera: Carabidae: Loricerinae). Alcheringa xx, xxx-xxx. ISSN 0311-5518.
Loricerinae is a small, distinctive subfamily of ground beetles, comprising only one genus Loricera Latreille. Only one fossil species is known to date. Here, we describe a new species, Loricera groehni sp. nov., belonging to Loricera based on a well-preserved adult in Eocene Baltic amber. Loricera groehni is tentatively attributed to the obsoleta group of the subgenus Loricera s.str. based on the relatively long antennomere 3 and punctate elytral interval 7. The discovery of a new species morphologically close to the extant Loricera species from western China and northern India suggests that the obsoleta group was more widespread in the Eocene than it is at present. The distribution pattern of Chinese Loricera is probably relictual. The fossil species, possessing conspicuous stiff setae on the basal antennomeres, was probably a specialized predator of springtails.
