Victor-Auguste Gauthier
Victor-Auguste Gauthier (5 March 1837 – 20 February 1911) was a French school teacher and amateur palaeontologist. He specialized in the study of fossilized sea urchins, contributing meticulous descriptions of many fossils found in southern France, Algeria, Tunisia and Persia. Life Victor-Auguste Gauthier was born in Tonnerre, Yonne, Tonnerre, Yonne, on 5 March 1837, son of a small winemaker. At an early age he was attracted to paleontology. He graduated from the College of Tonnerre, then was a ''maître répétiteur'' at the lycées of Sens and Orléans. He obtained a degree in Letters, then passed the ''agrégation'' in Grammar. He taught in turn at lycées in Pau, Pyrénées-Atlantiques, Pau, Le Puy, Gironde, Le Puy, Moulins, Allier, Moulins and finally, on 7 January 1864, at Marseille. During the nineteen years he spent in Marseille he devoted himself to the study of the Echinidae, a family of sea urchins, and made an important collection of the species of Provence. On 7 Au ...

Tonnerre, Yonne
Tonnerre () is a Communes of France, commune in the Yonne Departments of France, department in Bourgogne-Franche-Comté in north-central France. Geography Straddling the Canal de Bourgogne, the commune is situated at the following crossroads: *RD 965 (formerly RN 65) linking Auxerre 70 km to the west and Troyes 65 km to the north *RD 905 (formerly RN 5) linking Sens 70 km to the north and Dijon 125 km to the southeast, an historic route from Paris to Geneva. Neighboring communes Toponymy During the Roman era, Tonnerre was known as ''Tornodurum'', which was derived from the Lingone word for "fortress". It was the capital of ''Pagus Tornodorensis''. Here, in the valley of the Armançon, the County of Tonnerre was created, which served as a point of passage between Paris and Dijon, during a time when the King of France had designs on the Duchy of Burgundy. Three etymologies of Tonnerre are rooted in the Celtic era: it is derived from ''Torn,'' an obscu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Echinoderm
An echinoderm () is any animal of the phylum Echinodermata (), which includes starfish, brittle stars, sea urchins, sand dollars and sea cucumbers, as well as the sessile sea lilies or "stone lilies". While bilaterally symmetrical as larvae, as adults echinoderms are recognisable by their usually five-pointed radial symmetry (pentamerous symmetry), and are found on the sea bed at every ocean depth from the intertidal zone to the abyssal zone. The phylum contains about 7,600 living species, making it the second-largest group of deuterostomes after the chordates, as well as the largest marine-only phylum. The first definitive echinoderms appeared near the start of the Cambrian. Echinoderms are important both ecologically and geologically. Ecologically, there are few other groupings so abundant in the deep sea, as well as shallower oceans. Most echinoderms are able to reproduce asexually and regenerate tissue, organs and limbs; in some cases, they can undergo ...

Institut égyptien
An institute is an organizational body created for a certain purpose. They are often research organisations (research institutes) created to do research on specific topics, or can also be a professional body. In some countries, institutes can be part of a university or other institutions of higher education, either as a group of departments or an autonomous educational institution without a traditional university status such as a "university institute", or institute of technology. In some countries, such as South Korea and India, private schools are sometimes referred to as institutes; also, in Spain, secondary schools are referred to as institutes. Historically, in some countries, institutes were educational units imparting vocational training and often incorporating libraries, also known as mechanics' institutes. The word "institute" comes from the Latin word ''institutum'' ("facility" or "habit"), in turn derived from ''instituere'' ("build", "create", "raise" or "ed ...

Jacques De Morgan
Jean-Jacques de Morgan (3 June 1857 – 14 June 1924) was a French mining engineer, geologist, and archaeologist. He was the director of antiquities in Egypt during the 19th century, and excavated in Memphis and Dahshur, providing many drawings of many Egyptian pyramids. He also worked at Stonehenge, and Persepolis, and many other sites. He also went to Russian Armenia, as manager of a copper mine at Akhtala. "The Caucasus is of special interest in the study of the origins of metals; it is the easternmost point from which prehistoric remains are known; older than Europe and Greece, it still retains the traces of those civilizations that were the cradle of our own." In 1887-89 he unearthed 576 graves around Alaverdi and Akhatala, near the Tiflis- Alexandropol railway line. Early life He was born in Huisseau-sur-Cosson, Loir-et-Cher. His father Eugène, also called "Baron" de Morgan, was an engineer in mineral findings. His interests were in entomology and pre ...

Fish
A fish (: fish or fishes) is an aquatic animal, aquatic, Anamniotes, anamniotic, gill-bearing vertebrate animal with swimming fish fin, fins and craniate, a hard skull, but lacking limb (anatomy), limbs with digit (anatomy), digits. Fish can be grouped into the more basal (phylogenetics), basal jawless fish and the more common jawed fish, the latter including all extant taxon, living cartilaginous fish, cartilaginous and bony fish, as well as the extinct placoderms and acanthodians. In a break to the long tradition of grouping all fish into a single Class (biology), class (Pisces), modern phylogenetics views fish as a paraphyletic group. Most fish are ectotherm, cold-blooded, their body temperature varying with the surrounding water, though some large nekton, active swimmers like white shark and tuna can hold a higher core temperature. Many fish can communication in aquatic animals#Acoustic, communicate acoustically with each other, such as during courtship displays. The stud ...

Pentacrinites
''Pentacrinites'' is an extinct genus of crinoids that lived from the Hettangian to the Bathonian of Asia, Europe, North America, and New Zealand. Their stems are pentagonal to star-shaped in cross-section and are the most commonly preserved parts. ''Pentacrinites'' are commonly found in the ''Pentacrinites'' Bed of the Early Jurassic (Lower Lias) of Lyme Regis, Dorset, England. ''Pentacrinites'' can be recognized by the extensions (or cirri) all around the stem, which are long, unbranching, and of increasing length further down, the very small cup and 5 long freely branching arms. Description Like most echinoderms, ''Pentacrinites'' was composed of numerous calcite plates which were arranged into different body parts. ''Pentacrinites'' had 3 kinds of body parts: arms, cup ( calyx or theca) and stem. The stem consisted of a stack of numerous 5-sided beads (or columnal plates) with a canal at their centre. The stem had flexible appendages (or cirri) that were used to attach an i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bryozoa
Bryozoa (also known as the Polyzoa, Ectoprocta or commonly as moss animals) are a phylum of simple, aquatic animal, aquatic invertebrate animals, nearly all living in sedentary Colony (biology), colonies. Typically about long, they have a special feeding structure called a lophophore, a "crown" of tentacles used for filter feeder, filter feeding. Most Marine (ocean), marine bryozoans live in tropical waters, but a few are found in oceanic trenches and polar waters. The bryozoans are classified as the Stenolaemata, marine bryozoans (Stenolaemata), Phylactolaemata, freshwater bryozoans (Phylactolaemata), and Gymnolaemata, mostly-marine bryozoans (Gymnolaemata), a few members of which prefer brackish water. 5,869living species are known. Originally all of the crown group Bryozoa were colonial, but as an adaptation to a mesopsammal (interstitial spaces in marine sand) life or to deep-sea habitats, secondarily solitary forms have since evolved. Solitary species have been described i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brachiopod
Brachiopods (), phylum (biology), phylum Brachiopoda, are a phylum of animals that have hard "valves" (shells) on the upper and lower surfaces, unlike the left and right arrangement in bivalve molluscs. Brachiopod valves are hinged at the rear end, while the front can be opened for feeding or closed for protection. Two major categories are traditionally recognized, articulate and inarticulate brachiopods. The word "articulate" is used to describe the tooth-and-groove structures of the valve-hinge which is present in the articulate group, and absent from the inarticulate group. This is the leading diagnostic skeletal feature, by which the two main groups can be readily distinguished as fossils. Articulate brachiopods have toothed hinges and simple, vertically oriented opening and closing muscles. Conversely, inarticulate brachiopods have weak, untoothed hinges and a more complex system of vertical and oblique (diagonal) muscles used to keep the two valves aligned. In many brachio ...

Mollusca
Mollusca is a phylum of protostome, protostomic invertebrate animals, whose members are known as molluscs or mollusks (). Around 76,000 extant taxon, extant species of molluscs are recognized, making it the second-largest animal phylum after Arthropoda. The number of additional fossil species is estimated between 60,000 and 100,000, and the proportion of undescribed species is very high. Many taxa remain poorly studied. Molluscs are the largest marine biology, marine phylum, comprising about 23% of all the named marine organisms. They are highly diverse, not just in size and anatomical structure, but also in behaviour and habitat, as numerous groups are freshwater mollusc, freshwater and even terrestrial molluscs, terrestrial species. The phylum is typically divided into 7 or 8 taxonomy (biology), taxonomic class (biology), classes, of which two are entirely extinct. Cephalopod molluscs, such as squid, cuttlefish, and octopuses, are among the most neurobiology, neurologi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arnould Locard
Étienne Alexandre Arnould Locard (8 December 1841 – 28 October 1904), usually known as Arnould Locard, was a French naturalist, malacologist and geologist. His name can be abbreviated/spelled as Arnoul at plates, for example Crosse (1890).Joseph Charles Hippolyte Crosse, Crosse H. (1890). "Faune malacologique terrestre et fluvitile de l'Ille de la Trinité (Antilles)." ''Journal de conchyliologie'' 3835335. plate19. Biography Born in Lyon, he was the son of engineer Eugene Locard. He was a student at École Centrale Paris. He is considered one of the more prolific malacologists of the so-called "new school" with Jules René Bourguignat (1828–1892) as his master. Locard is credited with describing hundreds of zoological species, in particular freshwater mussels and gastropods from the genus ''Helix (gastropod), Helix''. During his career he did very little collecting of specimens himself, preferring to work in an institution/museum environment. In 1895, he revised the concho ...
