Middle Eocene
The Eocene ( ) is a geological epoch that lasted from about 56 to 33.9 million years ago (Ma). It is the second epoch of the Paleogene Period in the modern Cenozoic Era. The name ''Eocene'' comes from the Ancient Greek (''Ēṓs'', ' Dawn') and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch.See: *Letter from William Whewell to Charles Lyell dated 31 January 1831 in: * From p. 55: "The period next antecedent we shall call Eocene, from ήως, aurora, and χαινος, recens, because the extremely small proportion of living species contained in these strata, indicates what may be considered the first commencement, or ''dawn'', of the existing state of the animate creation." The Eocene spans the time from the end of the Paleocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by a brief period in which the concentration of the carbon isotope 13C in the atmosphere was exceptionally low in ...

Chamaebatiaria Creedensis
''Chamaebatiaria'' is a monotypic genus of aromatic shrub in the rose family containing the single species ''Chamaebatiaria millefolium'', which is known by the common names fern bush and desert sweet. Its genus name comes from its physical resemblance to the mountain miseries of genus ''Chamaebatia'', which are not closely related. (Referring to the subfamily by the name "Spiraeoideae") This is a hairy, sticky plant covered in fernlike foliage made up of fronds of small leaflets. At the ends of the erect branches of this spreading bush are inflorescence In botany, an inflorescence is a group or cluster of flowers arranged on a plant's Plant stem, stem that is composed of a main branch or a system of branches. An inflorescence is categorized on the basis of the arrangement of flowers on a mai ...s of white roselike flowers. This shrub is a resident of scrub, woodland, and forests in western North America. The closest relative of '' Spiraeanthus''. References External link ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Creede Formation
The Creede Formation is a geologic formation in Colorado, United States. It preserves fossils dating back to the Paleogene period, particularly many well-preserved fossil plants from Oligocene strata. The Formation was named by Emmons and Larsen in 1923. It stands out from the surrounding areas, which are mostly volcanic, as it is formed from deposits from surrounding waters. The formation has a vertical range of over 2,400 feet. Some examples of flora fossils found in the Creede Formation include conifers, Glumiflorae, Berberidaceae, and a broad-leaf tree Catalpa. The formation is unique as the only fossil plant locality from the Oligocene period found in the southern Rocky Mountains. The name comes from the town of Creede, Colorado. The Formation is near it, in the San Juan Mountains province.

The Priabonian is, in the International Commission on Stratigraphy, ICS's geologic timescale, the latest age (geology), age or the upper stage (stratigraphy), stage of the Eocene epoch (geology), Epoch or series (stratigraphy), Series. It spans the time between . The Priabonian is preceded by the Bartonian and is followed by the Rupelian, the lowest stage of the Oligocene. ''Priabona florissantius, Priabona'', an extinct dipteran of Pipunculidae family, is named after Priabonian, the age of deposits from which this insect is known. History and naming The Priabonian Stage was introduced in scientific literature by Ernest Munier-Chalmas and Albert de Lapparent in 1893. The stage is named after the small hamlet of Priabona (Monte di Malo), Priabona in the community of Monte di Malo, in the Veneto region of northern Italy.
