Equisetum Alexanderi
''Equisetum'' (; horsetail, snake grass, puzzlegrass) is the only living genus in Equisetaceae, a family (biology), family of Fern, ferns, which reproduce by spores rather than seeds. ''Equisetum'' is a "living fossil", the only living genus of the entire class (biology), subclass Equisetidae, which for over 100 million years was much more diverse and dominated the understorey of late Paleozoic forests. Some equisetids were large trees reaching to tall. The genus ''Calamites'' of the family Calamitaceae, for example, is abundant in coal deposits from the Carboniferous period. The pattern of spacing of nodes in horsetails, wherein those toward the apex of the shoot are increasingly close together, is said to have inspired John Napier to invent logarithms. Modern horsetails first appeared during the Jurassic period. A superficially similar but entirely unrelated flowering plant genus, mare's tail (''Hippuris''), is occasionally referred to as "horsetail", and adding to confusion, ...

In 1997 it is sent to coprolite specialist Karen Chin, who determines that this specimen of fossilized feces was attributable to ''Tyrannosaurus rex''. One year later, in 1998, Karen Chin and others publish a joint paper in ''Nature'' announcing the finding. * Paul Sereno lead an expedition to the Kem Kem region of southeastern Morocco. Among the fossils discovered is a partial skull of ''Carcharodontosaurus saharicus''.

Baltimartyria Proavitella
''Baltimartyria'' is an extinct genus of primitive metallic moths in the family Micropterigidae. The genus is solely known from the Early Eocene Baltic amber deposits in the Baltic Sea region of Europe. The genus currently contains two described species, ''Baltimartyria proavitella'' and ''Baltimartyria rasnitsyni''. ''B. proavitella'' The first known fossil was originally studied and described by Hans Rebel of the Austrian Academy of Sciences in Vienna, Austria. Rebel named the species ''Micropterix proavitella'', thinking it belonged to the modern genus '' Micropterix''. Rebel published his description of the species in 1936. The fossil was reexamined in 1995 by the Polish entomologist Andrzej W. Skalski, who recognized the species was not a member of ''Micropterix'' and moved the species to the new genus ''Baltimartyria''. ''B. rasnitsyni'' The second species of ''Baltimartyria'' described from Baltic amber is ''B. rasnitsyni'' which, like ''B. proavitella'', is know ...

Baltic Amber
The Baltic region is home to the largest known deposit of amber, called Baltic amber or succinite. It was produced sometime during the Eocene epoch, but exactly when is controversial. It has been estimated that these forests created more than 100,000 tons of amber. Today, more than 90% of the world's amber comes from Kaliningrad Oblast of Russia. It is a major source of income for the region; the local Kaliningrad Amber Combine extracted 250 tonnes of it in 2014, 400 tonnes in 2015. "Baltic amber" was formerly thought to include amber from the Bitterfeld Lignite, brown coal mines in Saxony (Eastern Germany). Bitterfeld amber was previously believed to be only 20–22 million years old (Miocene), but a comparison of the animal inclusions in 2003 suggested that it was possibly Baltic amber that was redeposited in a Miocene deposit. Further study of insect taxa in the ambers has shown Bitterfeld amber to be from the same forest as the Baltic amber forest, but separately deposited f ...

Early Eocene
In the geologic timescale the Ypresian is the oldest age or lowest 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 Belgian geologist André Hubert Dumont in 1850. The Ypresian is named after the Flemish city of Ypres in Belgium (spelled ''Ieper'' in Dutch). The definitions of the original stage were totally different from the modern ones. The Ypresian shares its name with the Belgian Ieper Group (French: ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hans Rebel
Hans Rebel (2 September 1861 – 19 May 1940) was an Austrian entomologist who specialised in Lepidoptera. Rebel, who had an early interest in natural history and butterflies, first became a lawyer. He devoted his spare time to studying Lepidoptera and established the entomological section of the Botanical and Zoological Society of Vienna. He succeeded Alois Friedrich Rogenhofer (1831–1897) as keeper of the Lepidoptera collection of the Naturhistorisches Museum in Vienna, a post he held from 1897 to 1932. Rebel enriched the collections and as a ''grand voyageur'', made many collecting trips in Austro-Hungary and five trips in the Balkans. He directed the Department of Zoology in 1923 and was the museum's director general in 1925. He published more than 300 publications on Lepidoptera and a catalogue of Palearctic butterflies Otto Staudinger (1830–1900) - ''Catalog Lepidopteren des palaearctischen Faunengebietes''.

Aristolochia Whitebirdensis
''Aristolochia'' () is a large plant genus with over 500 species that is the type genus of the family Aristolochiaceae. Its members are commonly known as birthwort, pipevine or Dutchman's pipe and are widespread and occur in the most diverse climates. Some species, like '' A. utriformis'' and '' A. westlandii'', are threatened with extinction. ''Isotrema'' is usually included here, but might be a valid genus. If so, it contains those species with a three-lobed calyx. Description ''Aristolochia'' is a genus of evergreen and deciduous lianas (woody vines) and herbaceous perennials. The smooth stem is erect or somewhat twining. The simple leaves are alternate and cordate, membranous, growing on leaf stalks. There are no stipules. The flowers grow in the leaf axils. They are inflated and globose at the base, continuing as a long perianth tube, ending in a tongue-shaped, brightly colored lobe. There is no corolla. The calyx is one to three whorled, and three to si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Smilax
''Smilax'' is a genus of about 300–350 species, found in the tropics and subtropics worldwide. In China for example about 80 are found (39 of which are endemic), while there are 20 in North America north of Mexico. They are climbing flowering plants, many of which are woody and/or thorny, in the monocotyledon family Smilacaceae, native throughout the tropical and subtropical regions of the world. Common names include ''catbriers'', ''greenbriers'', ''prickly-ivys'' and ''smilaxes''. ''Sarsaparilla'' (also zarzaparrilla, sarsparilla) is a name used specifically for the Jamaican '' S. ornata'' as well as a catch-all term in particular for American species. Occasionally, the non-woody species such as the smooth herbaceous greenbrier (''S. herbacea'') are separated as genus ''Nemexia''; they are commonly known by the rather ambiguous name ''carrion flowers''. Greenbriers get their scientific name from the Greek myth of Crocus and the nymph Smilax. Though this myth has numerous ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ralph Works Chaney
Ralph Works Chaney (August 24, 1890 – March 3, 1971) was an American paleobotanist. Early life Chaney was born on August 24, 1890 in Brainerd, Illinois. He attended Hyde Park Academy High School, and began to cultivate his interest in ornithology. He became an avid bird watcher and collected a series of bird eggs and skins. After his graduation, Chaney briefly moved to South Dakota before enrolling at the University of Chicago in the fall of 1908. It was here where his interests shifted from ornithology to botany, and eventually paleobotany. He earned his B.S. degree in geology from the University of Chicago in 1912. Career Chaney began to work towards a graduate degree in paleontology at the University of Chicago, studying under Stuart Weller. After two years, he found that he did not especially enjoy his Paleozoic studies. In the summer of 1913, he was hired as a cook by the U.S. Geological Survey and spent the summer months in the Matanuska Valley of Alaska. He was part ...
