内容説明・目次

内容説明

This systematic revision of the Bridge Creek flora is based on large collections of megafossil specimens from the John Day and Crooked River basins. The flora was found to be more diverse than previously recognized, with at least 125 species. At least 11 genera are extinct, but the majority are extant members of deciduous forests. The flora was derived from a variety of sources and represents a classic example of the broadleaved deciduous forests that became widespread at mid-latitiudes following the Eocene-Oligocene climatic cooling.
