Study of its fossils will enable researchers to understand how conifer plants distribute spatially and respond to climate changeĪs the first Metasequoia fossil in southwest China and the southernmost fossil of the genus around the world, the newfound fossils considerably expands the spatial distribution range of Metasequoia in the geological past.Īccording to the research published in Review of Palaeobotany and Palynology, the disappearance of Metasequoia in southwest China might be related to the evolutionary stasis of Metasequoia, most likely preventing necessary adaptations to increasing winter and spring aridity induced by the intensification of the Asian monsoon in this region during the Neogene. This living fossil flourished in North America during the Miocene (25 to 5 million years ago). The Metasequoia glyptostroboides Hu & W.C.Cheng (1948) is a monoecious, deciduous tree, 30-50 m tall with a diameter, at 1,5 m from the soil, up to 2,5 m, provided at the base of tabular roots (flattened roots similar to buttresses), with crown initially conical, then almost cylindrical, and brown-orange bark in the young plants tending with. ![]() The Metasequoia is an ancient plant with a narrow natural distribution in central China. Based on fossil evidence, the genus Metasequoia (Miki) was widely distributed in the temperate zones of eastern Asia and western North America by the early Late Cretaceous Period ( Momohara 1994 LePage et al. The Metasequoia genus was first described in the 1940s. By the end of the 1940s, that was found not to be the case. He proposed the genus name Metasequoia (after sequoia) and it is now. taxo diaceous genera Cryptomeria, Glyptostrobus and Taxodium (Ohsawa et al., 1993 ). Metasequoia glyptostroboides, popularly known in the west as the Dawn Redwood, had largely been believed to have become extinct millions of years ago. METASEQUOIA, ANOTHER LIVING FOSSIL INKGO BILOBA, a monotypic genus of very ancient lineage, in fact from the standpoint of geologic history, outside of the Cycadaceae, the most ancient of living trees, is often spoken of as a living fossil. Numerous well-preserved leafy shoots and seed cones of Metasequoia have been brought to light after a deep sleep of between about 16-11 million years ago at the middle Miocene deposits in Sanzhangtian village, southwest China's Yunnan Province, by researchers from Xishuangbanna Tropical Botanical Garden. There are two fascinating and favorite stories about living fossil trees, which. ![]() BEIJING, April 6 (Xinhua) - Chinese researchers have discovered a Metasequoia fossil in southwest China, the furthest south such a fossil that has ever been discovered, revealing a possible cause for the Metasequoia's disappearance in the region.
