With the basic sedimentology and taphonomy of limestone buildups known in the Fort Payne Formation, a detailed systematic study of the crinoid fauna (Phylum Echinodermata) will be made. The Fort Payne Formation is Lower Mississippian (late Osagean; appoximately 350 million years old), and this study will be conducted in rocks from south-central Kentucky. Where these rocks are in the subsurface, they are oil and gas producers. Because crinoidal remains are the dominant component in the limestone buildups, it is vital to document fully their diversity and to understand their paleoecologic distribution. This will result in a better understanding of the origin and distribution of these limestones. Specific objectives of the proposed research include 1, species-level systematics of the Fort Payne crinoid fauna, including documentation of within-species variations from the large collections available; 2, determination of the crinoid species composition of Fort Payne paleocommunities; 3, evaluation of the faunal role in the differential development of limestone buildups; 4, integration of these data with crinois species distributions throughout the midcontinental U.S. in order to understand better the regional distributional controls on late Osagean crinoids. This research will result in the most thoroughly documented paleontologic study of the enigmatic Lower Mississippian Walsortian facies. Further the resulting knowledge of late Osagean crinoids will be one of the most comprehensive data sets available for Paleozoic macroinvertebrates. The resulting regional synthesis of systematics, facies distribution, paleogeography and community paleoecology will be a rich source for future research to which fundamental evolutionary and paleoecologic questions can be addressed.

利用佩恩堡地层中已知的石灰岩堆积物的基本沉积学和埋藏学，将对海百合动物群（棘皮动物门）进行详细的系统研究。 佩恩堡地层属于下密西西比阶（奥塞吉阶晚期；大约有 3.5 亿年的历史），这项研究将在肯塔基州中南部的岩石中进行。 这些岩石位于地下，是石油和天然气的产地。 由于海百合遗骸是石灰岩堆积物的主要组成部分，因此充分记录其多样性并了解其古生态分布至关重要。 这将有助于更好地了解这些石灰石的起源和分布。 拟议研究的具体目标包括 1、佩恩堡海百合动物群的物种级系统学，包括现有大量藏品中物种内变异的记录； 2、佩恩堡古群落海百合物种组成的测定； 3、评价动物区系在石灰岩堆积物差异发育中的作用； 4，将这些数据与整个美国大陆中部的海百合物种分布进行整合，以便更好地了解晚期奥塞奇海百合的区域分布控制。 这项研究将对神秘的下密西西比阶沃尔索阶相进行最详尽的古生物学研究。 此外，由此产生的有关奥色吉晚期海百合的知识将成为古生代大型无脊椎动物可用的最全面的数据集之一。 由此产生的系统学、相分布、古地理学和群落古生态学的区域综合将成为未来研究的丰富来源，可以解决基本的进化和古生态问题。
