Sequoiadendron chaneyi is an extinct species of tree in the Cupressaceae genus Sequoiadendron. Known from Miocene fossils found in Nevada and California, S. chaneyi is the oldest species of Sequoiadendron. The common use of the name "sequoia" generally refers to Sequoiadendron giganteum, which occurs naturally only in the various groves that exist on the western slopes of the Sierra Nevada of California.[1] S. chaneyi is considered the probable direct ancestor to the extant Sequoiadendron giganteum.[1]
