The Hamilton fossil deposit is a unique Pennsylvanian locality with a rich diversity of marine-to-terrestrial vertebrate, invertebrate and plant fossils. PI's will study (1) composition, phylogenetic implications and taphonomy of fauna and flora and (2) sedimentology, carbonate petrology and structural setting of the limestone in order to determine the overall paleoecology and depositional setting of the deposit. Mapping, coring, genetic microstratigraphy and sedimentology will give sediment-body geometry and precise lithostratigraphic correlation. Composition of the biota of different horizons will be studied to reveal community structure. Because many of the organisms present in the Hamilton deposit either are primitive stem groups or preserved embryos, the phylogenetic implications of this study are numerous and important. Taphonomic investigation will give additional information about the condition of the depositional environment and transport of biota. Results of the different studies will be integrated into a reconstruction of the paleoecology and paleoenvironment of the Hamilton area during deposition of this unique facies. Ultimately, we will compare the Hamilton deposit to other deposits that bear well-preserved fossils.

汉密尔顿化石存款是一个独特的宾夕法尼亚州的地方与丰富的海洋到陆地脊椎动物，无脊椎动物和植物化石的多样性。PI将研究（1）动物群和植物群的组成、系统发育意义和埋藏学，以及（2）石灰岩的沉积学、碳酸盐岩石学和结构背景，以确定存款的整体古生态学和沉积背景。绘图、取芯、成因微观地层学和沉积学将提供沉积体几何形状和精确的岩石地层对比。将研究不同层位生物群的组成，以揭示群落结构。由于汉密尔顿存款中存在的许多生物要么是原始干组或保存的胚胎，这项研究的系统发育的影响是众多的和重要的。埋藏学调查将提供有关沉积环境和生物群迁移状况的更多信息。不同研究的结果将被整合到重建的古生态和古环境的汉密尔顿地区在沉积过程中的这一独特的相。最后，我们将把汉密尔顿存款与其他保存完好的化石进行比较。
