In this paper, we discuss charcoalified foxtail millet grains dated to the middle to late Western Zhou Dynasty and collected from the Chenyuan archeological site in Shangluo, in China's southeastern Shaanxi Province. We assigned these specimens to the species Setaria italica based on the following characteristics: an obtuse chalazal apex with missing stigmatic remains; an undulant seed surface composed of rectangular cells with undulate anticlinal walls; an elongated and deeply depressed embryo extending to almost the full seed length; and spherical starch grains. We suggest that the spread of foxtail millet from its original northern distribution center to the southern slopes of the Qinling Mountains could be attributed to: its prominence across Zhou crop systems; the latter area's arid or subarid climate; and the migration south of Zhou people fleeing severe conflict between their nation and northern nomads.

夭国与散国族姓问题之辩说

中原文物 2007年第5期 38-41页

作者：杨亚长陕西省考古研究所陕西西安710054

夭国与散国曾是西周时期两个较著名的方国,对于其各自的族姓学术界存在不同的看法。但依据相关铜器铭文和文献记载,夭国为姜姓、散国为姬姓的观点应较为符合实际。

天亡簋与太公望

文博 2010年第1期 86-87页

作者：杨亚长陕西省考古研究院陕西西安市710054

天亡簋器主的名字叫天亡,孙作云先生认为天亡就是古书中的史佚,于省吾先生认为天亡是文献记载中的太公望。本文赞同天亡为太公望之说,并申述其理由。

龙岗寺遗址是仰韶文化半坡类型时期出土绿松石器最多的遗址,对这些绿松石器的研究不仅能够反映此期绿松石的工艺制作、佩戴使用及生产流通的情况,还是了解仰韶文化时期汉水流域、关中地区以及长江中游地域间交流关系的重要窗口。本文以龙岗寺绿松石矿源分析结果为线索,并结合绿松石的形制、出土背景及工艺观察进行综合研究,可以反映出不同时期的龙岗寺先民对不同种类绿松石的选择使用和佩戴习俗,进而反映史前鄂豫陕跨域间的交流互动。

近2～3年来,陕西省考古研究院科研人员再次对蓝田县的新街遗址进行了抢救性发掘,经过清理整理,发现于新街遗址灰坑、探沟和探方中的全新世鸟类骨骼共70件。鸟类化石均为分散保存骨骼,但此次发现的鸟类骨骼保存不仅数量多,而且形态也较完好,是国内全新世鸟类化石发现记录所罕见的。本文记述了对这批鸟类化石开展形态解剖学的鉴定,并系统完成分类学研究的成果,新街遗址中总计鸟类所属8目、8科、8属,共9种,其中以水生鸟类居多。此外,根据鸟类的生存习性及鸟类骨骼上残存的人工痕迹,还针对新街遗址全新世时期的环境和古人类的生活行为进行了全方位多角度的分析和推理,为新街遗址在传统考古学研究的基础上提供了全新的科学信息和有益的补充。
