Abstract

The potential applications of microCT scanning in the field of archaeobotany are only just beginning to be explored. The imaging technique can extract new archaeobotanical information from existing archaeobotanical collections as well as create new archaeobotanical assemblages within ancient ceramics and other artefact types. The technique could aid in answering archaeobotanical questions about the early histories of some of the world's most important food crops from geographical regions with amongst the poorest rates of archaeobotanical preservation and where ancient plant exploitation remains poorly understood. This paper reviews current uses of microCT imaging in the investigation of archaeobotanical questions, as well as in cognate fields of geosciences, geoarchaeology, botany and palaeobotany. The technique has to date been used in a small number of novel methodological studies to extract internal anatomical morphologies and three-dimensional quantitative data from a range of food crops, which includes sexually-propagated cereals and legumes, and asexually-propagated underground storage organs (USOs). The large three-dimensional, digital datasets produced by microCT scanning have been shown to aid in taxonomic identification of archaeobotanical specimens, as well as robustly assess domestication status. In the future, as scanning technology, computer processing power and data storage capacities continue to improve, the possible applications of microCT scanning to archaeobotanical studies will only increase with the development of machine and deep learning networks enabling the automation of analyses of large archaeobotanical assemblages.

Microct成像在古生物学研究中的应用。
显微CT扫描在古植物学领域的潜在应用才刚刚开始探索。成像技术可以从现有的古植物收藏中提取新的古植物信息,并在古代陶瓷和其他人工制品类型中创建新的古生物组合。这项技术可以帮助回答有关世界上一些最重要的粮食作物的早期历史的古植物学问题,这些作物来自古植物学保护率最差的地理区域,而这些地区对古植物开发的了解仍然很差。本文综述了显微CT成像在古植物学研究中的应用,以及在地学、地质考古学、植物学和古植物学等相关领域的应用。迄今为止,该技术已被用于少数新的方法学研究,以从一系列粮食作物中提取内部解剖形态和三维定量数据,其中包括有性繁殖的谷物和豆类,以及无性繁殖的地下储存器官(USOs)。microCT扫描产生的大型三维数字数据集已被证明有助于古植物标本的分类鉴定,并有力地评估驯化状态。未来,随着扫描技术、计算机处理能力和数据存储能力的不断提高,随着机器和深度学习网络的发展,微型CT扫描在古植物研究中的可能应用只会增加,从而实现大型古植物组合分析的自动化。

期刊介绍: The Journal of Archaeological Method and Theory, the leading journal in its field,  presents original articles that address method- or theory-focused issues of current archaeological interest and represent significant explorations on the cutting edge of the discipline.   The journal also welcomes topical syntheses that critically assess and integrate research on a specific subject in archaeological method or theory, as well as examinations of the history of archaeology.    Written by experts, the articles benefit an international audience of archaeologists, students of archaeology, and practitioners of closely related disciplines.  Specific topics covered in recent issues include:  the use of nitche construction theory in archaeology,  new developments in the use of soil chemistry in archaeological interpretation, and a model for the prehistoric development of clothing.  The Journal''s distinguished Editorial Board includes archaeologists with worldwide archaeological knowledge (the Americas, Asia and the Pacific, Europe, and Africa), and expertise in a wide range of methodological and theoretical issues.  Rated ''A'' in the European Reference Index for the Humanities (ERIH) Journal of Archaeological Method and Theory is rated ''A'' in the ERIH, a new reference index that aims to help evenly access the scientific quality of Humanities research output. For more information visit: http://www.esf.org/research-areas/humanities/activities/research-infrastructures.html Rated ''A'' in the Australian Research Council Humanities and Creative Arts Journal List.  For more information, visit: http://www.arc.gov.au/era/journal_list_dev.htm
