A new antiarch placoderm from the Emsian (Early Devonian) of Wuding,Yunnan, China

Pan, Z., Zhu, M., Zhu, Y. &; Jia, L., August 2017. A new antiarch placoderm from the Emsian (Early Devonian) of Wuding, Yunnan, China. Alcheringa 42, 10–21. ISSN 0311-5518.

Wufengshania magniforaminis, a new genus and species of the Euantiarcha (Placodermi: Antiarcha), is described from the late Emsian (Early Devonian) of Wuding, Yunnan, southwestern China. The referred specimens were three-dimensionally preserved in black shales, allowing a high-resolution computed tomography reconstruction of anatomical details. The new euantiarch is characterized by a large orbital fenestra, an arched exoskeletal band around the orbital fenestra and a developed obtected nuchal area of the skull roof. Maximum parsimony analysis, using a revised data-set of antiarchs with 44 taxa and 66 characters, resolves Wufengshania gen. nov. as a member of the Bothriolepididae, which is characterized by the presence of the infraorbital sensory canal diverging on the lateral plate, and the nuchal plate with orbital facets. New analysis supports a sister group relationship between Dianolepis and the Bothriolepididae. Luquanolepis, a coeval euantiarch from the neighboring site of the new form, is referred to the Asterolepidoidei and represents the basalmost and earliest member of the Asterolepidoidei.

述海日楼藏旧抄本《贾氏谈录》

宋太祖开宝三年(970),南唐清辉殿学士张洎奉命使宋,纪录宋典客、左补阙贾黄中谈话,撰成<贾氏谈录>一书.此书虽记唐代琐事,又仅一卷,"篇帙无多,然如牛李之党其初肇衅于口语,为史所未及,而<周秦行纪>一书,晁公武亦尝据此录以辨韦璀之诬.

从《申报》看苏州的私钱与禁私（1827-1877）

清代实行银钱平行本位,大数用银,小数用钱。制钱是民间主要的流通货币,银两只不过是国家财政和大宗贸易的计算出纳单位以及富裕人家的储藏手段。在清朝统治者入关前,就曾铸有“天命”、“天聪”两种铜钱,自顺治进关,到辛亥革命,前后历经十代皇帝,铸有十种年号钱。康熙、乾隆时代的铜钱质量、重量都很规范。     

史前先民的头饰习俗

依据考古发掘和文献资料,认为史前先民对头部的装饰手法多种多样,这在一定程度上反映了早期人类审美意识及淳朴的原始宗教信仰的多样化,同时也说明了古人对美的追求并非有了丰厚的物质条件才萌生的。     

浙江省平湖庄桥坟遗址出土石犁的保护修复

浙江平湖庄桥坟遗址出土的石犁是史前考古的新发现,属于痕迹文物。出土时木构件痕迹饱水,为暗褐色、开裂严重、整体呈腐蚀状,非常脆弱。针对器物的保存状况,因地制宜地制定一系列保护方法:木构件痕迹的脱水保护、底托的加固制作、木构件粘贴复原等,使文物得以长期保存。     

博物馆展览中考古文物的阐释模式

博物馆展览从器物描述、文物解读到主题阐释的发展和转变,是考古学与博物馆学学科发展的成果.而阐释理念的发展并不是“淘汰”或“取代”,描述、解读和主题阐释并不相互排斥.在具体的策展实践中,根据展览主题和展品类型,综合应用阐释手段,合理处理各个阐释层次之间的主次关系,以更有效地传递知识、信息,才是展览成功的关键所在.同时,博...     

五千年前陶质建材的测试研究

迄今为止的考古发掘表明,我国最早的陶质建材,应该是距今5500年左右的凌家滩“红陶块”。考古学家推测其原料为粘土矿物,烧成温度约800～1000℃,且其物理性能与砖质建材较为接近,应为“砖的雏形”,为此,本工作测试分析了凌家滩“红陶块”的物相组成、烧成温度、吸水率与抗压强度,同时对比分析了明砖、汉砖、现代砖的物理性能,发现“红陶块”系粘土原料在950℃以上温度烧制而成,其吸水率和抗压强度由外向内呈梯度变化,内层的抗压强度、吸水率接近于现代砖和汉砖,业已超过明砖样品,所有这些分析结果,皆支持考古学家关于凌家滩“红陶块”为砖的雏型的推测。     

盘庚迁都新议

盘庚迁殷,以往大多数学者认为是自奄迁于今之安阳洹南之殷墟,即今之小屯村一带.然而在今之洹南的考古发掘中,很难找到盘庚、小辛、小乙三王时期的文化遗存和遗物.随着考古发掘的扩大和发展,我们认为,盘庚始迁为漳南洹北的殷墟,历经小辛、小乙时期,至武丁时,都城稍稍南移,遂移至今洹南殷墟.盘庚始迁之漳南洹北,文献上称之为漳南之商丘,又可称亳、称殷.它与洹南之殷墟合则称之为殷(后世称之为殷墟),析则分别称亳与殷.由于盘庚、小辛、小乙居洹北仅二十多年,析称的史实遂被“二百七十三年更不徙都“的记载所湮没,致使人们忽略了盘庚始迁的这段历史.
