Early History of the Metazoa

PI将通过以下方式调查后生动物的早期历史： 获得新的现场和实验室数据， 构建一些关键类群的精确模型。 野外工作 建议将于1989年在苏联和 1990年在南澳进行;实验室研究将包括 这些方法将产生有关早期 矿物骨架;建模将主要使用2D 和3D计算机辅助设计（CAD）软件和有限元 分析（FEA）。 前寒武纪晚期的软体后生动物 （Ediacara动物群）和早寒武世钙质和磷酸盐 微化石将作为该项目的一部分进行研究。

PI will investigate the early history of the Metazoa by obtaining new field and laboratory data which may be used to construct accurate models of some key taxa. The field work proposed would be carried out in the Soviet Union in 1989 and in South Australia in 1990; the laboratory studies will include methods that will yield information about the nature of early mineral skeletons; and the modeling will be largely done using 2D and 3D computer-aided-design (CAD) software and finite element analysis (FEA). Both the late Precambrian soft-bodied metazoans (Ediacara Fauna) and early Cambrian calcareous and phosphatic microfossils will be studied as part of this project.
