I need some help identifying this plant fossil. It appears to be a fruit of some sort, as it has a prominent reddish stain that surrounds the entire fossil. This specimen was found in the upper strata of the Raging River Formation in King County, Washington state. While the Raging River Formation is primarily noted as a marine fossil facies, the report by J.D. Vine, (1969), lists "woody fragments of trees and leaves were found associated with the marine fossils, but specific species could not be identified." This specimen was found at site #648 as listed in the above report.
