EAR - 9909494Bonnie F. JacobsFossil plants from the Singida District of north-central Tanzania, dated at 46 million years old, are significant because they will provide important information about the evolution of living plant groups, the historical development of tropical African plant communities, and the climate for a time period and part of the world from which little is currently known. Studies of modern day plant communities show that leaf shape and size are related to the climate in which the plants live. This relationship will be applied to leaf fossils from Tanzania in order to provide quantitative information about temperature and rainfall 46 million years ago. These data will be of tangible value in testing computer climate models designed to study the ways in which the Earth's climate functions, how it has changed in the past, and how it may change in the future.

EAR - 9909494Bonnie F. Jacobs 坦桑尼亚中北部辛吉达区的植物化石具有 4600 万年的历史，具有重要意义，因为它们将提供有关现存植物群的进化、热带非洲植物群落的历史发展以及目前知之甚少的一段时期和世界部分地区的气候的重要信息。 对现代植物群落的研究表明，叶子的形状和大小与植物生存的气候有关。 这种关系将应用于坦桑尼亚的叶子化石，以提供有关 4600 万年前温度和降雨量的定量信息。 这些数据对于测试旨在研究地球气候运行方式、过去如何变化以及未来可能如何变化的计算机气候模型具有实际价值。
