0228426Parrish-JonesThis Americas award will support collaborative research between Dr. Judith T. Parrish-Jones of the University of Arizona and Dr. Oscar Alcober and Ms. Carina Colombi, Dr. Alcober's Ph.D. advisee, of Universidad Nacional de San Juan in Argentina for their work on the evolution of the Pangean megamonsoon.The Pangean megamonsoon was a global climate system whose history is relevant to understanding climate dynamics. The southwestern portion of Pangea, in what is now South America, has received little attention in the documentation of this climate system, particularly of the Triassic. A well-exposed and complete Triassic stratigraphic sequence in western Argentina (Ischigualasto Basin) can help address the gap in our knowledge of the Pangean record, and is the focus of this project. The Pis will conduct plant taphonomic studies in the Ischigualasto Basin. Plant taphonomy is a powerful method for paleoclimate interpretation and has not been applied widely in South America. Integrated with the sedimentologic studies by other workers and with the vertebrate taphonomy to be carried out by the Argentines, this study of the paleovegetation will provide an excellent record of the Triassic climate in this part of the world.

Parrish-Jones 博士和 Oscar Alcober 博士以及 Alcober 博士的博士生 Carina Colombi 女士之间的合作研究。阿根廷圣胡安国立大学的顾问，表彰他们在盘古巨型季风演化方面的工作。盘古巨型季风是一个全球气候系统，其历史与理解气候动态相关。 盘古大陆的西南部，即现在的南美洲，在该气候系统（尤其是三叠纪）的记录中很少受到关注。 阿根廷西部（伊斯奇瓜拉斯托盆地）暴露良好且完整的三叠纪地层序列有助于弥补我们对泛古纪记录的了解空白，也是本项目的重点。 Pis 将在伊斯奇瓜拉斯托盆地进行植物埋藏学研究。 植物埋藏学是解释古气候的有力方法，但在南美洲尚未得到广泛应用。 与其他工作人员的沉积学研究以及阿根廷人将进行的脊椎动物埋藏学相结合，这项古植被研究将为世界这一地区的三叠纪气候提供良好的记录。
