Collaborative Research: An Exceptional Window into Late Triassic Terrestrial Ecosystems from the Western United StatesByRandall Irmis, EAR-1349560, University of UtahSterling Nesbitt, EAR-1349554, Howard UniversityNathan Smith, EAR-1349654, Virginia TechAlan Turner, EAR-1349667, SUNY StonybrookABSTRACT Intellectual Merit: The Late Triassic (~235-201 million years ago) records one of the most dynamic intervals of Earth history. A critical time of paleoenvironmental and biotic turnover, this interval witnessed the origin of modern terrestrial ecosystems. The Hayden Quarry (HQ) represents a unique opportunity to establish an extensive multi-million-year biotic-paleoenvironmental archive from nonmarine strata. HQ and associated localities in the Upper Triassic Chinle Formation of northern New Mexico provide an unparalleled window into the evolution of terrestrial vertebrate ecosystems, including the rise of dinosaurs. The extremely well-preserved fossils of HQ include at least 12 major groups of Late Triassic vertebrates sampled from over 15,000 collected specimens. This project has two major goals: 1) to establish an integrated record of paleoenvironmental and faunal change in Upper Triassic strata of northern New Mexico; and 2) utilize the extraordinary HQ vertebrate assemblage to elucidate the evolutionary history of early Mesozoic archosauromorph reptiles. This project represents one of the first integrated studies of biotic response to paleoenvironmental changes in a terrestrial ecosystem during the rise of dinosaurs. Broader Impacts: PIs discoveries are assimilated into the education curriculum and new exhibits at the Ghost Ranch Museum of Paleontology, exposing over 2,000 K-12 students from Rio Arriba County to science (where 70% of residents belong to population groups traditionally underrepresented in science), including through class site visits to the Hayden Quarry itself. To date, forty-five graduate and undergraduate students from nine different institutions have participated in and received training through our Ghost Ranch field project. This project provides funding for a minimum of four graduate students and six undergraduates in fieldwork and research, including support for underrepresented groups in the geosciences (e.g., African-Americans and women). Research will be disseminated through both scholarly and popular publications, as well as media press releases (e.g., http://www.nsf.gov/tawa). Finally, data generated by the project will be contributed to NSF-supported publically accessible databases such as MorphoBank (http://www.morphobank.org) and the Paleobiology Database (http://paleodb.org/).

合作研究：美国西部晚三叠世陆地生态系统的特殊窗口作者：Randall Irmis，EAR-1349560，犹他大学Sterling Nesbitt，EAR-1349554，霍华德大学Nathan Smith，EAR-1349654，弗吉尼亚理工大学Alan Turner，EAR-1349667，纽约州立大学石溪分校摘要知识分子优点：晚期 三叠纪（约 235-2.01 亿年前）记录了地球历史上最具活力的时期之一。这一时期是古环境和生物更替的关键时期，见证了现代陆地生态系统的起源。海登采石场 (HQ) 提供了一个独特的机会，可以从非海洋地层建立广泛的数百万年生物古环境档案。新墨西哥州北部上三叠统钦利组的总部和相关地点为了解陆地脊椎动物生态系统的演变（包括恐龙的崛起）提供了无与伦比的窗口。 HQ 保存极其完好的化石包括从 15,000 多个采集标本中采集的至少 12 个主要类群的晚三叠世脊椎动物。该项目有两个主要目标：1）建立新墨西哥州北部上三叠世地层古环境和动物区系变化的综合记录； 2）利用非凡的HQ脊椎动物组合来阐明早期中生代主龙类爬行动物的进化史。该项目代表了恐龙崛起期间陆地生态系统古环境变化生物反应的首批综合研究之一。更广泛的影响：PI 的发现被融入到幽灵牧场古生物博物馆的教育课程和新展览中，让来自里奥阿里巴县的 2,000 多名 K-12 学生接触科学（该县 70% 的居民属于传统上在科学领域代表性不足的群体），包括通过课堂现场参观海登采石场本身。迄今为止，已有来自九个不同机构的 45 名研究生和本科生参加了我们的幽灵牧场实地项目并接受了培训。该项目为至少四名研究生和六名本科生的实地考察和研究提供资金，包括为地球科学领域代表性不足的群体（例如非裔美国人和女性）提供支持。研究结果将通过学术和大众出版物以及媒体新闻稿（例如，http://www.nsf.gov/tawa）进行传播。最后，该项目生成的数据将贡献给 NSF 支持的可公开访问的数据库，例如 MorphoBank (http://www.morphobank.org) 和古生物学数据库 (http://paleodb.org/)。
