Paraconcavistylon Wehrii
''Paraconcavistylon'' is an extinct genus of flowering plant in the family Trochodendraceae comprises a single species, ''Paraconcavistylon wehrii''. The genus is known from fossil fruits and leaves found in the early Eocene deposits of northern Washington state, United States, and southern British Columbia, Canada. The species was initially described as a member of the related extinct genus '' Concavistylon'' as ''"Concavistylon" wehrii'', but subsequently moved to the new genus ''Paraconcavistylon'' in 2020 after additional study. Distribution and paleoenvironment ''Paraconcavistylon wehrii'' is known from specimens which were recovered from outcrops of the early Eocene, Ypresian Klondike Mountain Formation in Republic and coeval McAbee Fossil Beds near Cache Creek, British Columbia. The Klondike Mountain Formation and McAbee Fossil sites preserve upland temperate floras which were first interpreted as being microthermal, however further study has shown the floras to be more ...

Ypresian
In the geologic timescale the Ypresian is the oldest age (geology), age or lowest stage (stratigraphy), stratigraphic stage of the Eocene. It spans the time between , is preceded by the Thanetian Age (part of the Paleocene) and is followed by the Eocene Lutetian Age. The Ypresian is consistent with the lower Eocene. Events The Ypresian Age begins during the throes of the Paleocene–Eocene Thermal Maximum (PETM). The Fur Formation in Denmark, the Messel shales in Germany, the Oise amber of France and Cambay amber of India are of this age. The Eocene Okanagan Highlands are an uplands subtropical to temperate series of lakes from the Ypresian. Stratigraphic definition The Ypresian Stage was introduced in scientific literature by Belgium, Belgian geologist André Hubert Dumont in 1850. The Ypresian is named after the Flanders, Flemish city of Ypres in Belgium (spelled ''Ieper'' in Dutch). The definitions of the original stage were totally different from the modern ones. The Ypresi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxodium
''Taxodium'' is a genus of one to three species (depending on taxonomic opinion) of extremely flood-tolerant conifers in the cypress family, Cupressaceae. The generic name is derived from the Latin word ''taxus'', meaning " yew", and the Greek word ''εἶδος'' (''eidos''), meaning "similar to." Within the family, ''Taxodium'' is most closely related to Chinese swamp cypress (''Glyptostrobus pensilis'') and sugi (''Cryptomeria japonica''). Species of ''Taxodium'' occur in the southern part of the North American continent and are deciduous in the north and semi-evergreen to evergreen in the south. They are large trees, reaching tall and (exceptionally ) trunk diameter. The needle-like leaves, long, are borne spirally on the shoots, twisted at the base so as to appear in two flat rows on either side of the shoot. The cones are globose, diameter, with 10-25 scales, each scale with 1-2 seeds; they are mature in 7–9 months after pollination, when they disintegrate to release ...

Concavistylon Kvacekii
''Concavistylon'' is an extinct genus of flowering plant in the family Trochodendraceae comprising a single species ''Concavistylon kvacekii''. The genus is known from fossils found in Middle Miocene deposits of central Oregon. A second species '' "Concavistylon" wehrii'' was originally placed in ''Concavistylon'', but subsequently moved to a new genus ''Paraconcavistylon'' in 2020. Distribution and paleoenvironment ''Concavistylon kvacekii'' fossils were found in the Moose Mountain Flora, formerly called the Cascadia flora or Menagerie Wilderness flora, of Linn County, Oregon. The flora is included in the Little Butte Volcanic series outcropping near the town of Cascadia in the central Oregon Cascades. Work on the flora by paleobotanist Jack Wolfe in 1964 gave an estimated age of Early Miocene, this was later revised by Wolfe and Tanai in 1987 to a Late Oligocene estimation. In the descriptive paper naming ''Concavistylon'' Manchester ''et al.'' reported that radioisot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trochodendron
''Trochodendron'' is a genus of flowering plants with one living species, ''Trochodendron aralioides'', and six extinct species known from the fossil record. It was often considered the sole genus in the family Trochodendraceae, though botanists now also include the distinct genus '' Tetracentron'' in the family.

Paleocene
The Paleocene, ( ) or Palaeocene, is a geological epoch (geology), epoch that lasted from about 66 to 56 mya (unit), million years ago (mya). It is the first epoch of the Paleogene Period (geology), Period in the modern Cenozoic Era (geology), Era. The name is a combination of the Ancient Greek ''palaiós'' meaning "old" and the Eocene Epoch (which succeeds the Paleocene), translating to "the old part of the Eocene". The epoch is bracketed by two major events in Earth's history. The K–Pg extinction event, brought on by Chicxulub impact, an asteroid impact and possibly volcanism, marked the beginning of the Paleocene and killed off 75% of living species, most famously the non-avian dinosaurs. The end of the epoch was marked by the Paleocene–Eocene Thermal Maximum (PETM), which was a major climatic event wherein about 2,500–4,500 gigatons of carbon were released into the atmosphere and ocean systems, causing a spike in global temperatures and ocean acidification.

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] |
Rosetta Stone
The Rosetta Stone is a stele composed of granodiorite inscribed with three versions of a Rosetta Stone decree, decree issued in Memphis, Egypt, in 196 BC during the Ptolemaic dynasty on behalf of King Ptolemy V Epiphanes. The top and middle texts are in Egyptian language, Ancient Egyptian using Egyptian hieroglyphs, hieroglyphic and Demotic (Egyptian), Demotic scripts respectively, while the bottom is in Ancient Greek. The decree has only minor differences between the three versions, making the Rosetta Stone key to decipherment of ancient Egyptian scripts, deciphering the Egyptian scripts. The stone was carved during the Hellenistic period and is believed to have originally been displayed within a temple, possibly at Sais, Egypt, Sais. It was probably moved in late antiquity or during the Mamluk Sultanate (Cairo), Mamluk period, and was eventually used as building material in the construction of Fort Julien near the town of Rashid (Rosetta) in the Nile Delta. It was found there ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Morphotaxon
Paleobotany, which is 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. A synonym is paleophytology. It is a component of paleontology and paleobiology. The prefix ''palaeo-'' means "ancient, old", and is derived from the Greek adjective , . Paleobotany includes the study of terrestrial plant fossils, as well as the study of prehistoric marine photoautotrophs, such as photosynthetic algae, seaweeds or kelp. A closely related field is palynology, which is the study of fossilized and extant spores and pollen. Paleobotany is important in the reconstruction of ancient ecological systems and climate, known as paleoecology and paleoclimatology respectively; and is fundamental to the study of green plant development ...

Burke Museum
The Burke Museum of Natural History and Culture (Burke Museum) is a natural history museum in Seattle, Washington, in the United States. Established in 1899 as the Washington State Museum, it traces its origins to a high school naturalist club formed in 1879. The museum is the oldest in Washington state and boasts a collection of more than 16 million artifacts, including the world's largest collection of spread bird wings. Located on the campus of the University of Washington, the Burke Museum is the official state museum of Washington. History Young Naturalists Society The roots of the Burke Museum can be traced to a natural history club formed by high school students in the 19th century. The group was formed in December 1879 by students Edmond S. Meany, J. O. Young, P. Brooks Randolph, and Charles Denny. Denny's father, city founder Arthur Denny, was a regent of the Territorial University of Washington and arranged for the group to meet on campus. The Young Naturalists adop ...
