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 ...
The Copper Canyon Formation is a geologic formation in California. It preserves fossils dating back to the Neogene period. See also. Earth sciences portal;
Discoaster surculus fossil, 15 microns across. The extinction of this species officially marks the beginning of the Quaternary period. Calcareous nannofossils are a class of tiny (less than 30 microns in diameter [1]) microfossils that are similar to coccoliths deposited by the modern-day coccolithophores. [2]
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.

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.
It preserves fossils dating to the Miocene epoch of the Neogene period and is particularly noted for Canid fossils. [2] [3] This unit consists of loosely-consolidated sandstone that crumbles easily. These sands carry the water of the Ogallala Aquifer and is the source of much of the water in the Niobrara River. [1]
The identification of plant fossils in Cambrian strata is an uncertain area in the evolutionary history of plants because of the small and soft-bodied nature of these plants. It is also difficult in a fossil of this age to distinguish among various similar appearing groups with simple branching patterns, and not all of these groups are plants.
