Metasequoia was likely deciduous by this time. During the Paleocene and Eocene, extensive forests of Metasequoia occurred as far north as Strathcona Fiord on Ellesmere Island and sites on Axel Heiberg Island (northern Canada) at around 80° N latitude. Fossils are known from the Cenomanian onwards. Metasequoia redwood fossils are known from many areas in the Northern Hemisphere more than 20 fossil species have been named (some were even identified as the genus Sequoia), but are considered as just three species, M. foxii, M. milleri, and M. occidentalis.
Since its rediscovery in 1944, the dawn redwood has become a popular ornamental, with examples found in various parks in a variety of countries. Local villagers refer to the original tree from which most others derive as Shuǐshān (水杉), or "water fir", which is part of a local shrine. Although the shortest of the redwoods, it grows to at least 165 feet (50 meters) in height. The living species Metasequoia glyptostroboides is native to Lichuan county in Hubei province, China. Metasequoia, or dawn redwoods, is a genus of fast-growing deciduous trees, one of three species of conifers known as redwoods.
