The Arnold Arboretum of Harvard University then distributed the little seeds across the world, playing a big role in the tree’s international reinstatement and conservation. Colors may vary based on screen size and resolution. Long thought to be extinct, the Dawn Redwood (Metasequoia glyptostroboides) was discovered deep in a valley in central China in the 1940s. Moreover, our molecular evidence suggests that these molecules actually provide both the physical enforcement and chemical stability for maintaining the three-dimensional structures of these exceptional fossils. The Metasequoia sp. was named the Oregon state fossil back in 2005 but can be found in neighboring states such as Idaho, Montana, and Washington.įossil Type & Species: Compression & Metasequoia sp. Preserved for around fifty million years, these Metasequoia fossils possess the oldest biomolecules of this kind ever recovered. You are able to see the trees growing today, similar to the only living species of Gingko sp., Gingko biloba. This ancient redwood is a rapid-growing tree in the conifer family, similar to the California redwood. Seeds from this tree were brought back to the United States where they were propagated at various universities in an attempt to expand the species. The world believed Metasequoia glyptostroboides was an extinct species until its rediscovery in a secluded area of China in 1944. The Earth was significantly warmer during this time period, meaning this genus of trees was able to grow far into what is now northern Canada. Historically, the genus Metasequoia Hu et W.C. This "living fossil" flourished in North America during the Miocene (25 to 5 million years ago). Metasequoia glyptostroboides Hu et W.C.Cheng (Cupressaceae) is a relic plant with a narrow natural distribution in central China. The Metasequoia genus was first described in the 1940s. Dawn redwood, (Metasequoia glyptostroboides), ancient conifer from central China, the only living species of its genus.
