PI will spend a month (August, 2002) in China studying primitive Middle Cambrian echinoderms from the Kaili Fauna at the Guizhou University of Technology in Guiyang as well as at the Nanjing Institute of Geology and Paleontology in Nanjing. There are very good possibilities that primary symmetry in echinoderms (based on the symmetry of the ambulacral system), early evolutionary development of columnar structures and their holdfasts can be deduced from some of the material. Most specimens are preserved as molds and extensive latex casting will be an important part of the data gathering. At present there is good evidence that the sediments associated with the fossils are not extensively bioturbated, which makes the mode/mechanism of attachment to the bottom very important: it will be extensively investigated. Study of this material may well open up a whole new understanding of the early evolution of this important biotic group and the collections are available at this time for joint investigation with Chinese colleagues.

PI将于2002年8月在中国的贵州工业大学和南京地质古生物研究所进行一个月的研究，研究凯里动物群中的原始中寒武世棘皮动物。 有很好的可能性，棘皮动物的主要对称性（基于步带系统的对称性），早期进化发展的柱状结构和他们的holdfasts可以从一些材料推断。大多数标本保存为模具和广泛的乳胶铸造将是数据收集的重要组成部分。 目前，有充分的证据表明，与化石有关的沉积物没有广泛的生物扰动，这使得附着到底部的模式/机制非常重要：它将被广泛研究。 对这些材料的研究可能会为这一重要生物群的早期进化提供一个全新的认识，目前这些标本可供与中国同事联合调查。
