9705289 COLLINS The emergence of the Isthmus of Panama split apart a single tropical ocean, an event which had a profound impact on organismal evolution, ecologic systems and oceanic circulation. Fossils preserved in Eastern Pacific and Caribbean deposits comprise successive tropical American biotas that changed dramatically through the last 15 million years in response to the constriction and closure of the great Caribbean - Pacific seaway. Research based on Pacific and Caribbean collections of fossils will address these changes. The main goal of this project is a paleobiotic survey of shallow-water fossil faunas of coastal Ecuador, for comparison with Caribbean faunas of similar age and environment that were collected previously. This project, by Laurel Collins and colleagues, involves collecting Neogene marine fossils in Ecuador, preparing and identifying these collections, determining the ages and paleoenvironments of their stratigraphic sequences, designing a new database for the data, making the project's data available on the Internet, and using the collections in research. The identified faunas will include calcareous nannoplankton, foraminifera, ahermatypic corals, bryozoans, echinoderms, mollusks, ostracods and fish. The new model for the database will track the progress of preparing collections and identifying taxa, aid in dating samples and correlating strata, and serve as the repository for all faunal occurrence data, maps, stratigraphic sections, and locality information. Research based on these data will result in the most accurate assessment to date of the long-term effects of environmental change and isolation on marine biotas, and the data model will set the standard for field-based paleobiotic surveys.

9705289 Collins的出现巴拿马地峡的出现分开了一个热带海洋，这一事件对有机进化，生态系统和海洋循环产生了深远的影响。保存在东太平洋和加勒比海矿床的化石包括连续的热带美国生物群岛，这些生物群在过去的1500万年中发生了巨大变化，以应对大加勒比海太平洋海道的收缩和关闭。基于太平洋和加勒比化石收集的研究将解决这些变化。该项目的主要目的是对沿海厄瓜多尔浅水化石动物群的古生物调查，用于与以前收集的类似年龄和环境的加勒比群落进行比较。 该项目由劳雷尔·柯林斯（Laurel Collins）及其同事，涉及在厄瓜多尔（Ecuador）收集新生金海洋化石，准备和识别这些收藏品，确定其地层序列的年龄和古环境，设计一个新数据库，为数据提供新的数据库，使该项目在Internet上可用，并在研究中使用了集合。已确定的动物群将包括钙质的Nannoplankton，有孔虫，Ahermatypic Corals，Bryozoans，Echinoderms，Mollusks，Ostracods和Fish。数据库的新模型将跟踪准备收集和识别分类单元，帮助样本和关联地层的进度，并充当所有动物出现数据，地图，地层剖面和局部信息的存储库。 基于这些数据的研究将导致最准确的评估环境变化和隔离对海洋生物群的长期影响，并且数据模型将为基于现场的古生物调查设定标准。
