Metasequoia glyptostroboides (dawn redwood cone) 3 Metasequoia glyptostroboides, the dawn redwood, is not an angiosperm - it is a conifer native to parts of China.Ĭlassification: Plantae, Pinophyta, Pinopsida, Pinales, CupressaceaeĮn./wiki/Metasequoia_glyptostroboides This domination was due to the evolutionary success of flowers, which are structures that greatly aid angiosperm reproduction. They quickly dominated Earth's terrestrial ecosystems, and have dominated ever since. They first unambiguously appeared in the fossil record during the Cretaceous. The most conspicuous group of living plants is the angiosperms, the flowering plants. Occasional mass extinction events temporarily removed much of Earth's plant ecosystems - this occurred at the Permian-Triassic boundary (251 million years ago) and the Cretaceous-Tertiary boundary (65 million years ago). Earth's continents have been partly to mostly covered with forests ever since the Late Devonian. Earth's initial forestation event occurred during the Middle to Late Paleozoic. During the Devonian, the first trees and forests appeared. Fossil root traces in paleosol horizons are known in the Ordovician. Land plant body fossils are known in Silurian sedimentary rocks - they are small and simple plants (e.g., Cooksonia). The oldest known land plants in the fossil record are Ordovician to Silurian. Most species occupy terrestrial environments, but they also occur in freshwater and saltwater aquatic environments. ![]() Plants are multicellular, photosynthesizing eucaryotes.
