SGER: Studies of Selected Cambrian and Precambrian Fossils

寒武纪和前寒武纪化石的研究Ellis L.Yochelson(EAR-0331863)PI计划一个由三部分组成的SGER研究项目。这包括(1)重新研究贝基1898年的泰勒瀑布软体动物动物群；(2)对水锥软体动物的调查；(3)对元古代生命演化中的“霍洛迪斯基亚”的评价。子项目1和子项目2将完成目前正在进行的研究，子项目3与在澳大利亚和蒙大拿州发现的一些元古界遗迹化石有关，这可能为最早的高等真核生物提供强有力的证据。如果这是正确的，这将倒退700英里。已知的最早的动物直接证据。

Studies of Selected Cambrian and Precambrian FossilsEllis L. Yochelson(EAR-0331863)PI plans a three-part SGER research project. These include a (1) restudy of Berkey's 1898 Taylor Falls Mollusca fauna; (2) Investigations of hyseloconid Mollusca; and (3) Evaluation of "Horodyskia" in the evolution of Proterozoic life. Subprojects 1 and 2 will complete research currently underway and the 3rd subproject relates to some Proterozoic trace fossils found in Australia and Montana that may provide strong evidence of the earliest higher eukaryotes. If correct this would set back by 700 m.y. the earliest known direct evidence of animals.
