The Popotosa Formation is the original locality for the Socorro flora, estimated to be 20 to 15 million years old. The Socorro flora is notable for its impressions of juniper foliage, angiosperm leaflets, and floral parts.
Based on fossil evidence, some have proposed that the ancestors of the angiosperms diverged from an unknown group of gymnosperms in the Triassic period (245–202 million years ago). Fossil angiosperm-like pollen from the Middle Triassic (247.2–242.0 Ma) suggests an older date for their origin, which is further supported by genetic evidence ...
The Copper Canyon Formation is a geologic formation in California. It preserves fossils dating back to the Neogene period. See also. Earth sciences portal;
The presence of bodies of flowing water like rivers or streams is recorded in the terrestrial sediments of the Catahoula Formation. Fossils from this ancient environment are rare, but include petrified wood. [11] During the Miocene epoch of the ensuing Neogene period west-central Louisiana held a coastal plain.
The Neogene (/ ˈ n iː. ə dʒ iː n / NEE-ə-jeen, [6] [7]) is a geologic period and system that spans 20.45 million years from the end of the Paleogene Period 23.04 million years ago to the beginning of the present Quaternary Period 2.58 million years ago.
Very few Archean stromatolites contain fossilized microbes, but fossilized microbes are sometimes abundant in Proterozoic stromatolites. [ 16 ] While features of some ancient apparent stromatolites are suggestive of biological activity, others possess features that are more consistent with abiotic (non-biological) precipitation. [ 17 ]
Paleobotany, also spelled as palaeobotany, is the branch of botany dealing with the recovery and identification of plant remains from geological contexts, and their use for the biological reconstruction of past environments (paleogeography), and the evolutionary history of plants, with a bearing upon the evolution of life in general.
The Neogene spans from 23.03 million to 2.58 million years ago. It features two epochs: the Miocene and the Pliocene. [59] The Miocene spans from 23.03 million to 5.333 million years ago and is a period in which grass spread further across, effectively dominating a large portion of the world, diminishing forests in the process.
