Sequoiadendron is a genus of evergreen trees, with three species, only one of which survives to the present:[1]
- Sequoiadendron giganteum, extant, commonly known as wellingtonia, giant redwood and giant sequoia,[2] growing naturally in the Sierra Nevada mountains of California[3]
- † Sequoiadendron chaneyi, the predecessor of Sequoiadendron giganteum, found mostly in the Nevada area of the Tertiary Colorado Plateau until the late Miocene[4]
- †Sequoiadendron tchucoticum Late Cretaceous; Enmyvaam River Basin, Russia[5]
Fossil record
[edit]
Sequoiadendron fossil pollen and macrofossils may have been found as early as the Late Cretaceous[5] and throughout the Northern Hemisphere,[6] including locations in western Georgia in the Caucasus region.[7]
