Prodryas
''Prodryas persephone'' is an extinct species of brush-footed butterfly, known from a single specimen from the Chadronian-aged Florissant Shale Lagerstatte of Late Eocene Colorado. ''P. persephone'' is the first fossil butterfly to be found in North America, and is exquisitely well preserved. Its closest extant relatives are the mapwings and African admirals of the genera ''Hypanartia'' and ''Antanartia'', respectively. Significance The type specimen, now held at the Museum of Comparative Zoology of Harvard University, was the first fossil butterfly to be found in North America, and has been described as "possibly the best fossil butterfly specimen ever found". The appearance of a figure of ''Prodryas'' in Samuel Hubbard Scudder's book ''Frail Children of the Air'' influenced the paleontologist Frank M. Carpenter to embark on his career. Scudder exhibited the specimen at the Royal Entomological Society of London in December 1893. Description The single known specimen of ''P ...

Butterfly
Butterflies are insects in the macrolepidopteran clade Rhopalocera from the Order (biology), order Lepidoptera, which also includes moths. Adult butterflies have large, often brightly coloured wings, and conspicuous, fluttering flight. The group comprises the large superfamily (zoology), superfamily Papilionoidea, which contains at least one former group, the skippers (formerly the superfamily "Hesperioidea"), and the most recent analyses suggest it also contains the moth-butterflies (formerly the superfamily "Hedyloidea"). Butterfly fossils date to the Paleocene, about 56 million years ago. Butterflies have a four-stage life cycle, as like most insects they undergo Holometabolism, complete metamorphosis. Winged adults lay eggs on the food plant on which their larvae, known as caterpillars, will feed. The caterpillars grow, sometimes very rapidly, and when fully developed, pupate in a chrysalis. When metamorphosis is complete, the pupal skin splits, the adult insect climbs o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charlotte Hill
Charlotte Hill (1849–1930) was a homesteader born in Indiana who contributed to paleontology through finding several significant fossil within the Florissant Fossil Beds. She sold many fossils to other collectors and investigators to earn money on the side. Her most significant discovery was the Persephone butterfly near Florissant, Colorado. Charlotte's discoveries brought attention to Florissant as an important location for fossils, and her findings created an impetus for recognition of the fossil beds as a national monument within the United States of America. Many of her collected fossils now reside in the Harvard University museum and the Smithsonian's Museum of Natural History. The fossil rose ''Rosa hilliae'' was named after Charlotte Hill in 1883. Early life Hill was born on February 15, 1849, in Indiana. She migrated west from Indiana, pioneering into the then-new settlement of Colorado City in 1874. Charlotte married her husband, Adam Hill, at the age of thirtee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Samuel Hubbard Scudder
Samuel Hubbard Scudder (April 13, 1837 – May 17, 1911) was an American entomologist and paleontologist. He was a leading figure in entomology during his lifetime and the founder of insect paleontology in America. In addition to fossil insects, he was an authority on butterflies (Lepidoptera) and grasshoppers (Orthoptera). Biography Scudder was born on April 13, 1837, in Boston, Massachusetts, the son of Charles Scudder and Sarah Lathrop (Coit) Scudder. His father was a successful merchant, and both parents had Puritan roots dating back to the founding of the Massachusetts Bay Colony in the 1620s. He was raised in a strict Calvinist Congregational household.Leach (2013) One of his younger brothers, Horace Scudder, became a noted author and editor of the ''Atlantic Monthly'',Cockerell (1911) while his niece Vida Dutton Scudder was a writer and social activist. Scudder attended Boston Latin School, and then enrolled in Williams College in 1853 at the age of 16. He studied with na ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Entomologist's Record And Journal Of Variation
''The Entomologist's Record and Journal of Variation'' is a bimonthly peer-reviewed entomological journal. Its emphasis is British and European Lepidoptera, but material on other insect orders is also published regularly. It was established by J. W. Tutt in 1890. Its current editor is Colin W. Plant. Two long-running series featured in the journal are the annual reports on immigration of Lepidoptera into the British Isles, and an annual review of the Microlepidoptera recorded from Britain. The ''Entomologist's Record and Journal of Variation'' became a publication of the Amateur Entomologists' Society The Amateur Entomologists' Society (AES) is a UK organisation for people interested in insects. History Based in the UK, the Amateur Entomologists' Society was founded in 1935 as The Entomological Exchange and Correspondence Club, for the purpo ... in January 2009.

Compression Fossil
A compression fossil is a fossil preserved in sedimentary rock that has undergone physical compression. While it is uncommon to find animals preserved as good compression fossils, it is very common to find plants preserved this way. The reason for this is that physical compression of the rock often leads to distortion of the fossil. The best fossils of leaves are found preserved in fine layers of sediment that have been compressed in a direction perpendicular to the plane of the deposited sediment. Since leaves are basically flat, the resulting distortion is minimal. Plant stems and other three-dimensional plant structures do not preserve as well under compression. Typically, only the basic outline and surface features are preserved in compression fossils; internal anatomy is not preserved. These fossils may be studied while still partially entombed in the sedimentary rock matrix where they are preserved, or once lifted out of the matrix by a peel or transfer technique. Compr ...

Homestead Principle
The homestead principle is the principle by which one gains ownership of an unowned natural resource by performing an act of original appropriation. Appropriation could be enacted by putting an unowned resource to active use (as with using it for produce some product), joining it with previously acquired property or by marking it as owned (as with livestock branding). Proponents of intellectual property hold that ideas can also be homesteaded by originally creating a virtual or tangible representation of them. Others argue that since tangible manifestations of a single idea will be present in many places, including within the minds of people, this precludes their being owned in most or all cases. Homesteading is one of the foundations of Rothbardian anarcho-capitalism and right-libertarianism. In political philosophy John Locke In his 1690 work ''Second Treatise of Government'', Enlightenment philosopher John Locke advocated the Lockean proviso which allows for homes ...

Geological Society Of America
The Geological Society of America (GSA) is a nonprofit organization dedicated to the advancement of the geosciences. History The society was founded in Ithaca, New York, in 1888 by Alexander Winchell, John J. Stevenson, Charles H. Hitchcock, John R. Procter and Edward Orton and has been headquartered at 3300 Penrose Place, Boulder, Colorado, US, since 1967. GSA began with 100 members under its first president, James Hall. In 1889 Mary Emilie Holmes became its first female member. It grew slowly but steadily to 600 members until 1931, when a nearly $4 million endowment from 1930 president R. A. F. Penrose Jr. jumpstarted GSA's growth. As of December 2017, GSA had more than 25,000 members in over 100 countries. The society has six regional sections in North America, three interdisciplinary interest groups, and eighteen specialty divisions. Activities The stated mission of GSA is "to advance geoscience research and discovery, service to society, stewardship of Earth, an ...

Engraving
Engraving is the practice of incising a design onto a hard, usually flat surface by cutting grooves into it with a Burin (engraving), burin. The result may be a decorated object in itself, as when silver, gold, steel, or Glass engraving, glass are engraved, or may provide an Intaglio (printmaking), intaglio printing plate, of copper or another metal, for printing images on paper as prints or illustrations; these images are also called "engravings". Engraving is one of the oldest and most important techniques in printmaking. Wood engraving is a form of relief printing and is not covered in this article, same with rock engravings like petroglyphs. Engraving was a historically important method of producing images on paper in artistic printmaking, in mapmaking, and also for commercial reproductions and illustrations for books and magazines. It has long been replaced by various photographic processes in its commercial applications and, partly because of the difficulty of learning th ...

Royal Entomological Society Of London
The Royal Entomological Society is devoted to the study of insects. Its aims are to disseminate information about insects and improving communication between entomologists. The society was founded in 1833 as the Entomological Society of London. It had many antecedents beginning as the Society of Entomologists of London. History The foundation of the society began with a meeting of "gentlemen and friends of entomological science", held on 3 May 1833 in the British Museum convened by Nicholas Aylward Vigors with the presidency of John George Children. Those present were the Reverend Frederick William Hope, Cardale Babington, William Yarrell, John Edward Gray, James Francis Stephens, Thomas Horsfield, George Thomas Rudd and George Robert Gray. Letters of Adrian Hardy Haworth, George Bennett and John Curtis were read where they expressed their regrets to be unable to attend the meeting. They decided that a society should be created for the promotion of the science of entomology ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shale
Shale is a fine-grained, clastic sedimentary rock formed from mud that is a mix of flakes of clay minerals (hydrous aluminium phyllosilicates, e.g. kaolin, Al2 Si2 O5( OH)4) and tiny fragments (silt-sized particles) of other minerals, especially quartz and calcite.Blatt, Harvey and Robert J. Tracy (1996) ''Petrology: Igneous, Sedimentary and Metamorphic'', 2nd ed., Freeman, pp. 281–292 Shale is characterized by its tendency to split into thin layers ( laminae) less than one centimeter in thickness. This property is called '' fissility''. Shale is the most common sedimentary rock. The term ''shale'' is sometimes applied more broadly, as essentially a synonym for mudrock, rather than in the more narrow sense of clay-rich fissile mudrock. Texture Shale typically exhibits varying degrees of fissility. Because of the parallel orientation of clay mineral flakes in shale, it breaks into thin layers, often splintery and usually parallel to the otherwise indistinguishable beddin ...
