Trypanosoma Antiquus
''Trypanosoma antiquus'' is an extinct species of kinetoplastid (class Kinetoplastida), a monophyletic group of unicellular parasitic flagellate protozoa. The genus name is derived from the Greek ''trypano'' (borer) and ''soma'' (body) because of their corkscrew-like motion, and the species name from ''antiquua'' (old) reflecting the age of the specimen. All trypanosomes are heteroxenous (requiring more than one obligatory host in order to complete life cycle) or are transmitted through some variation of a vector. The species was described in 2005 by George Poinar Jr. in the journal Vector-Borne & Zoonotic Diseases from metatrypanosomes preserved in several fecal pellets encased in '' Hymenaea protera'' amber. The fossil was recovered in the Dominican Republic from early Miocene Burdigalian stage deposits on the island of Hispaniola. Included with the pellets and thought to be the origin for them, is the extinct kissing bug '' Triatoma dominicana''. This association is ...

Pollen Cone
A conifer cone (in formal botanical usage: strobilus, plural strobili) is a seed-bearing organ on gymnosperm plants. It is usually woody, ovoid to globular, including scales and bracts arranged around a central axis, especially in conifers and cycads. The cone of Pinophyta (conifer clade) contains the reproductive structures. The woody cone is the female cone, which produces seeds. The male cone, which produces pollen, is usually herbaceous and much less conspicuous even at full maturity. The name "cone" derives from Greek ''konos'' (pine cone), which also gave name to the geometric cone. The individual plates of a cone are known as ''scales''. The ''umbo'' of a conifer cone refers to the first year's growth of a seed scale on the cone, showing up as a protuberance at the end of the two-year-old scale. The male cone (microstrobilus or pollen cone) is structurally similar across all conifers, differing only in small ways (mostly in scale arrangement) from species to spe ...

Fothergilla Malloryi Without Scale 01
''Fothergilla'' (witch alder) is a genus of two to four species of flowering plants in the family Hamamelidaceae, native to woodland and swamps of the southeastern United States. They are low-growing deciduous shrubs growing to tall with downy twigs. The brush-like flowers are produced before the leaves in spring on terminal spikes; they do not have any petals, but a conspicuous cluster of white stamens 2–3 cm long. The leaves are alternate, broad ovoid, 4–10 cm long and 3–8 cm broad, with a coarsely toothed margin; they are noted for their brilliant orange or red fall colors.

Fothergilla Malloryi
''Fothergilla malloryi'' is an extinct species of flowering plant in the family Hamamelidaceae known from fossil leaves found in the early Eocene Klondike Mountain Formation deposits of northern Washington state. The ''F. malloryi'' leaves are the earliest appearance in the fossil record of a member of the witchalder genus ''Fothergilla'', which includes the living species '' F. gardenii'', and '' F. major'', both of which are native to the southeastern United States. The genus also includes three or four other fossil species with two Asian Miocene species, '' F. viburnifolia'' from China, '' F. ryozenensis'' from Japan along with one Miocene North American species, '' F. praeolata'' of Oregon. '' Fothergilla durhamensis'' described from Eocene sediments in King County, Washington is considered dubious in placement, and it was transferred to the genus '' Platimeliphyllum'' by Huegele ''et al.'' (2021). History and classification ''Fothergilla malloryi'' is represented by a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Corylopsis Readae SRIC Img1
''Corylopsis'' is a genus of nearly 30 species of shrubs in the witch hazel family, Hamamelidaceae, native to eastern Asia with the majority of species endemic to China but with some also in Japan, Korea, and the Himalayas. This genus is also known from the extinct species '' Corylopsis reedae'' described from Eocene leaf fossils found in Washington State, USA. They grow to tall, often with a crown wider than the shrub's height. The leaves are ovate with an acute apex and a serrated margin, long and broad. The flowers are produced in late winter in pendulous racemes long with 5-30 flowers; each flower has five pale yellow petals, 4–9 mm long. The fruit is a dry capsule 10–12 mm long, containing two glossy black seed A seed is an embryonic plant enclosed in a protective outer covering, along with a food reserve. The formation of the seed is a part of the process of reproduction in seed plants, the spermatophytes, including the gymnosperm and angio ...

Klondike Mountain Formation
The Klondike Mountain Formation is an Early Eocene (Ypresian) geological formation located in the northeast central area of Washington state. The formation, named for the type location designated in 1962, Klondike Mountain north of Republic, Washington, is composed of volcanic rocks in the upper unit and volcanics plus lacustrine (lakebed) sedimentation in which a lagerstätte with exceptionally well-preserved plant and insect fossils has been found, along with fossil epithermal hot springs. The formation is the youngest in a group of formations which belong to the Challis Sequence rocks. The formation unconformably overlies rocks of the Eocene Sanpoil Volcanics and much older Triassic and Permian formations. The formation is bounded on its edges by a series of high-angle strike slip faults, which have contained the Klondike Mountain Formation in a series of graben structures, such as the Republic Graben. Public access to a fossiliferous outcrop at the north end of Republic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Corylopsis Reedae
''Corylopsis reedae'' is an extinct species of flowering plant in the family Hamamelidaceae known from fossil leaves found in the early Eocene Klondike Mountain Formation deposits of northern Washington state. ''C. readae'' is one of the oldest occurrences of the winter-hazel genus ''Corylopsis'', which includes between seven and thirty species, all found in Asia. Fossils from two other occurrences are of similar age to ''C. readae'', with Paleocene specimens from Greenland being placed in the form taxon ''Corylopsiphyllum'' and an Eocene Alaskan fossil being included in ''Corylopsis'' without species placement. History and classification ''Corylopsis reedae'' is represented by a single counterpart compression fossil specimen from the Ypresian-aged Klondike Mountain Formation that outcrops in Republic, Ferry County, Washington. The age of the formation is based on Argon–argon dating, which has returned a date of 49.4 ±0.5 million years old. The fossil was recovered f ...

Infructescence
Infructescence (fruiting head) is defined as the ensemble of fruits derived from the ovaries of an inflorescence. It usually retains the size and structure of the inflorescence. In some cases, infructescences are similar in appearance to simple fruits. These are called multiple fruits. One example is the infructescence of ''Ananas'', which is formed from the fusion of the berries with receptacle tissues and bracts. The mature infructescence of a grain, such as wheat or maize, is known as an ear. The infructescence of ''Ficus'' is called a syconium Syconium (plural ''syconia'') is the type of inflorescence borne by figs (genus ''Ficus''), formed by an enlarged, fleshy, hollow receptacle with multiple ovaries on the inside surface. In essence, it is really a fleshy stem with a number of flow .... References Fruit morphology {{botany-stub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Horseshoe Canyon Formation
The Horseshoe Canyon Formation is a stratigraphic unit of the Western Canada Sedimentary Basin in southwestern Alberta. It takes its name from Horseshoe Canyon, an area of badlands near Drumheller. The Horseshoe Canyon Formation is part of the Edmonton Group and is up to thick. It is of Late Cretaceous age, Campanian to early Maastrichtian stage (Edmontonian Land-Mammal Age), and is composed of mudstone, sandstone, carbonaceous shales, and coal seams. A variety of depositional environments are represented in the succession, including floodplains, estuarine channels, and coal swamps, which have yielded a diversity of fossil material. Tidally-influenced estuarine point bar deposits are easily recognizable as Inclined Heterolithic Stratification (IHS). Brackish-water trace fossil assemblages occur within these bar deposits and demonstrate periodic incursion of marine waters into the estuaries. The Horseshoe Canyon Formation crops out extensively in the area around Drumheller, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
