The flora of the Eastover Formation consists mostly of lignitized plant remains and a documented palynoflora record. The terrestrial palynoflora represented in the Eastover Formation consisted primarily of temperate -warm temperate taxa.
The fossil history of flowering plants records the development of flowers and other distinctive structures of the angiosperms, now the dominant group of plants on land.The history is controversial as flowering plants appear in great diversity in the Cretaceous, with scanty and debatable records before that, creating a puzzle for evolutionary biologists that Charles Darwin named an "abominable ...
Period: Neogene Epoch : Earliest Miocene ( Aquitanian ) to early Miocene ( Burdigalian ) in the eastern Florida panhandle, to middle Miocene ( Serravallian ) in northern Florida, Georgia, and South Carolina, and to earliest Pliocene ( Zanclean ) in southern Florida, ~23 to ~3.6 mya a period of 19.4 million years [ 6 ]
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.
It is of particular interest for its fine preservation, including of reproductive structures. The flora is dominated by Calliandra leaflets but also contains Juniperus [2] The formation has yielded a fossil of the pig-like oreodont Merychyus major major from an arroyo near San Antonito. [5]
In the south-central Andes, an arid period occurred from 6.1 to 5.2 Ma, with another occurring from 3.6 to 3.3 Ma. These arid periods are coincident with global cold periods, during which the position of the Southern Hemisphere westerlies shifted northward and disrupted the South American Low Level Jet, which brings moisture to southeastern ...
The first fossil records of vascular plants, that is, land plants with vascular tissues, appeared in the Silurian period. The earliest known representatives of this group (mostly from the northern hemisphere) are placed in the genus Cooksonia. They had very simple branching patterns, with the branches terminated by flattened sporangia.
