Metasequoia, or dawn redwood, is a genus of fast-growing coniferous trees, one of three species of conifers known as redwoods. The living species Metasequoia glyptostroboides is native to Lichuan county in Hubei province, China. Although the shortest of the redwoods, it grows to at least 165 feet (50 meters) in height.
The floodplain of Metasequoia Valley in Hubei had already been turned to rice paddies by the time of the tree's discovery, but was once probably a more extensive dawn redwood forest. Such a forest would have been similar to bald cypress forests in the United States, with many similar species growing in association. Nearly 3,000 trunks were ...
Cheirolepidiaceae (also spelled Cheirolepidaceae) is an extinct family of conifers.They first appeared in the Triassic, and were a diverse and common group of conifers during most of the Mesozoic era, primarily at low latitudes, [1] where they often formed a dominant element of the vegetation. [2]
Conifer: Redwood National Park, California, United States Western North America [1] [2] It reached 116.07 metres (380.8 ft) in 2019. [3] The second and sixth tallest trees, both redwoods, were also found at Redwood National Park in 2006 when Hyperion was found, and were named Helios 114.8 metres (377 ft), and Icarus 113.1 metres (371 ft) tall.

Scientists say they have found new evidence that there is a hidden planet in our solar system. For years, some astronomers have been suggesting that unusual behaviour on the edge of our solar ...
Many of us were granted an opportunity to create a time capsule in high school. It probably didn’t matter as much then, but unearthing it decades later brought a glorious sense of nostalgia and ...
A group of the world's leading planet formation experts decided at a conference in 2006 [8] on the following definition of a planetesimal: A planetesimal is a solid object arising during the accumulation of orbiting bodies whose internal strength is dominated by self-gravity and whose orbital dynamics is not significantly affected by gas drag ...
The time capsule, unearthed in April during demolition of the oldest section of the hospital's legacy campus on Greenlawn Avenue, was stashed inside the building's cornerstone, a cement block ...
