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.
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 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 ...
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.
Scientists working in southwest England have found the oldest fossilized forest known on Earth, according to a new study. Fossilized trees dating back 390 million years are world’s oldest Skip ...
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]
