Abstract

ABSTRACT Kincaid Shelter (Uvalde County, Texas) contains a sequence of vertebrate and cultural remains spanning from the late Pleistocene to Historic. Kincaid Shelter perhaps is best known for its Paleoindian component, including a cobblestone floor interpreted as a Clovis habitation surface. Zone 3 lacustrine sediments are beneath that cobblestone floor and yielded a diverse late Pleistocene vertebrate fauna. Recovered in 1948, the assemblage has never been formally studied or described. The current analysis focuses on the composition, paleoecology, and taphonomy of the Zone 3 faunal assemblage to establish and clarify this important late Pleistocene record. Sixteen vertebrate taxa are represented. Large mammals predominate, but reptiles, including American alligator, and a bird also occur. The presence of Bison antiquus and Panthera atrox indicate a late Pleistocene (Rancholabrean Land Mammal Age) age for the faunal assemblage. The Zone 3 faunal composition is typical of latest Pleistocene faunas from the Great Plains and supports an interpretation of a grassland biome.

美国德克萨斯州中部Kincaid Shelter (41UV2) 3带晚更新世脊椎动物多样性与古生态

德克萨斯州Uvalde县的Kincaid Shelter包含一系列从晚更新世到历史时期的脊椎动物和文化遗迹。金凯德避难所可能以其古印第安人的组成部分而闻名，包括一块被解释为克洛维人居住表面的鹅卵石地板。3区湖泊沉积物位于鹅卵石地板下方，并产生了多种晚更新世脊椎动物动物群。该组合于1948年被发现，从未被正式研究或描述过。目前的分析主要集中在3区动物组合的组成、古生态学和分类学上，以建立和澄清这一重要的晚更新世记录。有16个脊椎动物分类群。主要是大型哺乳动物，但也有爬行动物，包括美洲鳄和鸟类。古野牛和Panthera atrox的存在表明该动物群处于晚更新世(Rancholabrean陆生哺乳动物时代)。3区动物群组成是大平原最新更新世动物群的典型特征，支持对草原生物群系的解释。

期刊介绍： PaleoAmerica disseminates new research results and ideas about early human dispersal and migrations, with a particular focus on the Americas. It fosters an interdisciplinary dialog between archaeologists, geneticists and other scientists investigating the dispersal of modern humans during the late Pleistocene. The journal has three goals: First and foremost, the journal is a vehicle for the presentation of new research results. Second, it includes editorials on special topics written by leaders in the field. Third, the journal solicits essays covering current debates in the field, the state of research in relevant disciplines, and summaries of new research findings in a particular region, for example Beringia, the Eastern Seaboard or the Southern Cone of South America. Although the journal’s focus is the peopling of the Americas, editorials and research essays also highlight the investigation of early human colonization of empty lands in other areas of the world. As techniques are developing so rapidly, work in other regions can be very relevant to the Americas, so the journal will publish research relating to other regions which has relevance to research on the Americas.
