The Sam Noble Museum (SNM) of the University of Oklahoma will join a Thematic Collections Network (TCN) of ten other institutions with extensive holdings of fossils from rocks that formed in a shallow sea, termed the Western Interior Seaway, which bisected North America during the late Cretaceous Period (65-100 million years ago). The late Cretaceous was a time of warmer, "greenhouse" climates and higher sea levels than those of today, and environments may have been similar to those predicted for the middle of the next century under some scenarios of anthropogenic greenhouse gas emissions. The data made available through this TCN offer an opportunity to answer a variety of questions dealing with the impact of climatic and sea level change on marine communities, and may provide critical information for predicting future outcomes for modern marine biodiversity. This project will digitize collection data from the SNM and make them accessible to the scientific community, industry, K-16 educators and students, and the public via a variety of web portals. Additional societal impacts of the project are made through a collaboration with the Education Department at the SNM, which will develop a field- and lab-based teacher workshop and web resources, and produce curricula that focus on biotic and environmental change over time, including sea level change, continental drift and other geological phenomena. The project also contributes to training of university students in modern digitization techniques and the generation of biodiversity data from museum collections, with up to five students participating annually.The Invertebrate Paleontology Collection at the SNM will digitize data for about 13,000 specimens from 450 localities at the northern and southern ends of the seaway, and thereby expand both the paleogeographic and paleoenvironmental reach of the project. Of particular importance are localities from the far northern margin of the seaway in Alaska and northwestern Canada that extend geographic coverage of the project by at least 4,000 km. They will allow the geographic ranges of species to be assessed fully, and will also provide insight into latitudinal variability in paleocommunity composition. The SNM?s holdings also include about 7,500 specimens from 240 localities in southern Oklahoma. They record paleocommunities in coastal regions of the seaway that lie shoreward of localities in Texas that will be contributed by other partners in the project. These data "fill in" the more proximal end of a shallow marine environmental gradient near the southern margin of the seaway, thereby expanding the scope of the project into onshore environments. Data will be aggregated by the TCN and shared with iDigBio (www.idigbio.org).

俄克拉荷马大学的Sam Noble博物馆（SNM）将加入其他十个机构的主题收藏网络（TCN），并拥有从浅海中形成的岩石中广泛持有的化石，称为西部内部海道，该海道被称为西部北美，该岩石是在后期北美分配的（65-1亿年前）。 晚白垩纪是一个温暖，“温室”气候和海平面更高的时期，在人为温室气体排放的某些情况下，环境可能与下一世纪中叶预测的环境相似。 通过此TCN提供的数据提供了一个机会，可以回答有关气候和海平面变化对海洋社区影响的各种问题，并可能为预测现代海洋生物多样性的未来成果提供关键信息。该项目将对SNM的收集数据进行数字化，并使科学界，行业，K-16教育者和学生以及通过各种Web门户都可以访问它们。 该项目的其他社会影响是通过与SNM的教育部门的合作来产生的，SNM将开发一个基于现场和实验室的教师研讨会和网络资源，并制作课程，专注于随着时间的推移，包括海平面变化，大陆漂移和其他地质现象，包括生物和环境变化。 该项目还有助于对大学生进行现代数字化技术的培训以及博物馆收藏中的生物多样性数据的产生，每年最多五名学生参加。SNM的无脊椎动物古生物学收藏集将对大约13,000个标本的数据数字化，该数据来自北部和南部端，并在此范围内扩展了Opeplogemecopraph和Plastighatiroragraphy and Plastion the Plastion and plovive thatevirriarch。 特别重要的是，来自阿拉斯加海道和加拿大西北部海路北部边缘的地区，将项目的地理覆盖范围延长了至少4,000公里。 它们将允许对物种的地理范围进行充分的评估，还将洞悉古社区组成的纬度变异性。 SNM持有量还包括来自俄克拉荷马州南部240个地区的约7,500个标本。 他们记录了在海路的沿海地区的古社区，这些地方位于德克萨斯州地区的地方，该地区将由该项目的其他合作伙伴贡献。这些数据“填充”了海道南部边缘附近浅海环境梯度的近端端，从而将项目的范围扩展到了陆上环境中。 数据将由TCN汇总并与IDIGBIO（www.idigbio.org）共享。
