Fossil Woods of Chilga, Ethiopia.

Although Chilga, Ethiopia is now dominated by pasture and sparse woodland, it once supported large forest trees during the Oligocene. Silicified stumps of these trees are now found in situ. Identification of the wood of these stumps to their nearest living relatives, and analysis of the wood physiognomy of the assemblage, indicates that the Oligocene climate must have been wetter, with a much shorter dry season.
