The Oligocene dawn redwood "Metasequoia occidentalis" is the Oregon state fossil. The third is "Metasequoia glyptostroboides", the dawn redwood. Among those is one of Germany's "oldest" dawn redwood trees (Metasequoia glyptostroboides). Pizhou City is home to the longest Dawn redwood "Metasequoia glyptostroboides" avenue in the world. It is one of three extinct species belonging to the redwood genus "Metasequoia". On the Alaska North Slope, "Metasequoia" was the dominant conifer. "Metasequoia occidentalis" appeared in fossil record during the Late Cretaceous epoch (Cenomanian stage). Symbiotic mycorrhizal relationships have also been discovered in roots of "Pinus" and "Metasequoia". It is one of three extinct species of "Metasequoia" that are currently recognized as valid. Two families of Pinopsida are known&colon; Araucariaceae and Cupressaceae including "Metasequoia". Most modern phylogenies place "Sequoia" as sister to "Sequoiadendron" and "Metasequoia "as the out-group. Trees of "Metasequoia", from the single living species "Metasequoia glyptostroboides", are much smaller. Other notable species include the Metasequoia, the Para rubber tree and the Ginkgo. "Metasequoia foxii" was described from a selection of 10,147 fossils. "Metasequoia" was likely deciduous by this time.
