This project studies Antarctic fossil plants from the Beardmore Glacier area to understand seed plant evolution and paleoclimate in the Permian to Early Jurassic periods. These samples are unique in the exquisite preservation of cells and tissues, and may lead to new insights into the origin and evolution of both existing and extinct plants. As well, these fossil plants were adapted to a warmer, more CO2 rich world of the period, and may help predict how plants will evolve in the future. The broader impacts of this work include mentoring plans for women graduate students; outreach to students at all levels through public paleobotany workshops at the Kansas University Museum; and training of preservice K12 teachers.

本项目研究南极Beardmore冰川地区的植物化石，了解二叠纪至早侏罗世种子植物的进化和古气候。这些样本在细胞和组织的精致保存方面是独一无二的，可能会对现存和灭绝植物的起源和进化产生新的见解。此外，这些化石植物适应了那个时期更温暖、二氧化碳含量更高的世界，这可能有助于预测未来植物将如何进化。这项工作的更广泛影响包括女研究生指导计划；通过在堪萨斯大学博物馆举办的公共古植物学研讨会，与各级学生进行接触；培训K12职前教师。
