9316455 Wheeler PIs will investigate the paleoclimatic utility of Tertiary fossil woods by focusing on wood assemblages from strata that have also yielded leaf and/or fruit floras that have played an important role in the interpretation of paleoclimatic change in the western U.S. (Eocene Clarno Formation, Oregon; Miocene Vantage Forest, Wwashington State). Two approaches--comparison with extant floras and evaluation of xylem physiognomy--will be used. Work will help develop a methododolgy for using wood anatomy to infer paleoclimates that is independent of other methods.

9316455惠勒 PI将调查第三纪化石木材的古气候效用，重点关注来自地层的木材组合，这些地层也产生了在美国西部古气候变化的解释中发挥重要作用的叶和/或水果植物群（始新世克拉诺组，俄勒冈州;中新世Vantage森林，华盛顿州）。 将采用两种方法--与现存植物区系的比较和木质部外貌的评价。 工作将 帮助开发一种独立于其他方法的使用木材解剖学来推断古气候的方法。
