This project involves reconstructing the evolutionary history of a major group of fossil trilobites, the family Cheiruridae. The investigators will conduct a global survey of relevant fossil species, using data from the published literature, existing field collections, new field collections, and museum specimens. Evolutionary history will be reconstructed using modern quantitative methods. Hypotheses about relationships will then be applied to a range of important questions in paleobiology, shedding light on subjects such as the nature of mass extinctions, biogeography, and rates of speciation. Knowledge of evolutionary relationships is a basic requirement for understanding the history of life on Earth, yet modern quantitative methods have not always been applied to the study of fossil animals. The project seeks to redress this by using phylogenetic analysis to consider a diverse and important fossil group; further, this study will potentially serve as a model for the use of fossils to address major evolutionary questions. The project will train several students in evolutionary systematics, will serve public and K-12 education via a website and traveling museum exhibit, and will also serve the broader discipline by generating new data and also linking these data to existing biological databases.

该项目涉及重建主要的化石三叶虫（Cheiruridae）的进化史。研究人员将使用已发表的文献，现有的现场收集，新田间收集和博物馆标本的数据对相关化石物种进行全球调查。进化史将使用现代定量方法重建。然后，关于关系的假设将应用于古生物学中的一系列重要问题，阐明了诸如大规模灭绝，生物地理和物种速率的主题。对进化关系的了解是理解地球生命历史的基本要求，但是现代定量方法并不总是应用于化石动物的研究。该项目旨在通过使用系统发育分析来考虑一个多样化和重要的化石群来纠正这一点。此外，这项研究将有可能作为使用化石来解决重大进化问题的模型。该项目将通过网站和旅行博物馆展览培训几个学生的进化系统学，将为公众和K-12教育提供服务，还将通过生成新数据并将这些数据链接到现有的生物数据库来为更广泛的学科服务。
