Eoligiiscus
''Eoligiiscus tarraconensis'' is an extinct species of woodlouse, the only species in the genus ''Eoligiiscus''. It was found preserved in amber at the Peñacerrada I amber site in Burgos, Spain. The preserved specimens date from Late Albian period. Etymology The genus name comes from Eos, the Greek goddess of dawn; the related genus ''Ligia''; and the Greek suffix -''iskos'', commonly used in wooldlouse genera names. The species epithet comes from Roman province Hispania Tarraconensis Hispania Tarraconensis was one of three Roman provinces in Hispania. It encompassed much of the northern, eastern and central territories of modern Spain along with modern North Region, Portugal, northern Portugal. Southern Spain, the region now ...; the site where the woodlouse was found lies within the historical boundaries of that province.

Woodlouse
Woodlice are terrestrial isopods in the suborder Oniscidea. Their name is derived from being often found in old wood, and from louse, a parasitic insect, although woodlice are neither parasitic nor insects. Woodlice evolved from marine isopods which are presumed to have colonised land in the Carboniferous, though the oldest known fossils are from the Cretaceous period. This makes them quite unique among the crustaceans, being one of the few lineages to have transitioned into a fully terrestrial environment. Woodlice have many common names and although often referred to as terrestrial isopods, some species live semiterrestrially or have recolonised aquatic environments like those of the genus ''Ligia''. Woodlice in the families Armadillidae, Armadillidiidae, Eubelidae, Tylidae and some other genera can roll up into a roughly spherical shape (:wiktionary:conglobate, conglobate) as a defensive mechanism or to conserve moisture; others have partial rolling ability, but most cannot ...

Amber
Amber is fossilized tree resin. Examples of it have been appreciated for its color and natural beauty since the Neolithic times, and worked as a gemstone since antiquity."Amber" (2004). In Maxine N. Lurie and Marc Mappen (eds.) ''Encyclopedia of New Jersey'', Rutgers University Press, . Amber is used in jewelry and as a healing agent in Traditional medicine, folk medicine. There are five classes of amber, defined on the basis of their chemical constituents. Because it originates as a soft, sticky tree resin, amber sometimes contains animal and plant material as Inclusion (mineral), inclusions. Amber occurring in coal seams is also called resinite, and the term ''ambrite'' is applied to that found specifically within New Zealand coal seams. Etymology The English word ''amber'' derives from Arabic from Middle Persian 𐭠𐭭𐭡𐭫 (''ʾnbl'' /ambar/, “ambergris”) via Medieval Latin, Middle Latin ''ambar'' and Middle French ''ambre''. The word referred to what is n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Burgos
Burgos () is a city in Spain located in the autonomous community of Castile and León. It is the capital and most populous municipality of the province of Burgos. Burgos is situated in the north of the Iberian Peninsula, on the confluence of the Arlanzón (river), Arlanzón river tributaries and at the edge of the Meseta Central, central plateau. The municipality has a population of about 180,000 inhabitants. The Camino de Santiago pilgrimage route runs through Burgos. Founded in 885 by the second Count of Castile, Diego Rodríguez Porcelos, Burgos soon became the leading city of the embryonic County of Castile. The 11th century chieftain El Cid, Rodrigo Díaz de Vivar (''El Cid'') had connections with the city: born near Burgos, he was raised and educated there. Burgos experienced a long decline from the 17th century onwards. Burgos became the headquarters of the Francoist proto-government (1936–1939) following the start of the Spanish Civil War. Declared in 1964 as Pole of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Late Albian
The Albian is both an age of the geologic timescale and a stage in the stratigraphic column. It is the youngest or uppermost subdivision of the Early/Lower Cretaceous Epoch/Series. Its approximate time range is 113.0 ± 1.0 Ma to 100.5 ± 0.9 Ma (million years ago). The Albian is preceded by the Aptian and followed by the Cenomanian. Stratigraphic definitions The Albian Stage was first proposed in 1842 by Alcide d'Orbigny. It was named after Alba, the Latin name for River Aube in France. A Global Boundary Stratotype Section and Point (GSSP), ratified by the IUGS in 2016, defines the base of the Albian as the first occurrence of the planktonic foraminiferan '' Microhedbergella renilaevis'' at the Col de Pré-Guittard section, Arnayon, Drôme, France. The top of the Albian Stage (the base of the Cenomanian Stage and Upper Cretaceous Series) is defined as the place where the foram species '' Rotalipora globotruncanoides'' first appears in the stratigraphic column.

Ligia
''Ligia'' is a genus of isopods, commonly known as rock lice or sea slaters. Most ''Ligia'' species live in tidal zone cliffs and rocky beaches, but there are several fully terrestrial species which occur in high-humidity environments. Ecology Coastal ''Ligia'' species exhibit a mixture of terrestrial and marine characteristics, drying out easily, needing moist air and proximity to water to retain water. While they have gills and can exchange gas under water, they only do so when escaping terrestrial predators or being dislodged by wave action. They do not move swiftly in the water and are open to marine predation. They are well adapted to rocky surfaces and avoid sand, which opens them to terrestrial predation and desiccation. Taxonomy It has been suggested that ''Ligia'' is more closely related to marine isopods than it is to true woodlice Woodlice are terrestrial isopods in the suborder Oniscidea. Their name is derived from being often found in old wood, and from lou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hispania Tarraconensis
Hispania Tarraconensis was one of three Roman provinces in Hispania. It encompassed much of the northern, eastern and central territories of modern Spain along with modern North Region, Portugal, northern Portugal. Southern Spain, the region now called Andalusia, was the province of Hispania Baetica. On the Atlantic west lay the province of Lusitania, partially coincident with modern-day Portugal. History Establishment The Phoenicians and Carthaginians colonised the Mediterranean coast of Iberia in the 8th to 6th centuries BC. The Greeks later also established colonies along the coast. The Romans arrived in the 2nd century BC during the Second Punic War. The province Hispania Citerior Tarraconensis was established in the reign of Augustus as the direct successor of the Roman Republican province of Hispania Citerior ("nearer Hispania"), which had been ruled by a propraetor.Livy, ''The History of Rome'', 41.8. The roots of the Augustan reorganisation of Hispania are found in Pomp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Isopoda
Isopoda is an order of crustaceans. Members of this group are called isopods and include both aquatic species and terrestrial species such as woodlice. All have rigid, segmented exoskeletons, two pairs of antennae, seven pairs of jointed limbs on the thorax, and five pairs of branching appendages on the abdomen that are used in respiration. Females brood their young in a pouch under their thorax called the marsupium. Isopods have various feeding methods: some eat dead or decaying plant and animal matter, others are grazers or filter feeders, a few are predators, and some are internal or external parasites, mostly of fish. Aquatic species mostly live on the seabed or the bottom of freshwater bodies of water, but some taxa can swim for short distance. Terrestrial forms move around by crawling and tend to be found in cool, moist places. Some species are able to roll themselves into a ball as a defense mechanism or to conserve moisture like species in the family Armadilli ...

Crustaceans Described In 2021
Crustaceans (from Latin meaning: "those with shells" or "crusted ones") are invertebrate animals that constitute one group of arthropods that are traditionally a part of the subphylum Crustacea (), a large, diverse group of mainly aquatic arthropods including decapods (shrimps, prawns, crabs, lobsters and crayfish), seed shrimp, branchiopods, fish lice, krill, remipedes, isopods, barnacles, copepods, opossum shrimps, amphipods and mantis shrimp. The crustacean group can be treated as a subphylum under the clade Mandibulata. It is now well accepted that the hexapods (insects and entognathans) emerged deep in the Crustacean group, with the completed pan-group referred to as Pancrustacea. The three classes Cephalocarida, Branchiopoda and Remipedia are more closely related to the hexapods than they are to any of the other crustaceans (oligostracans and multicrustaceans). The 67,000 described species range in size from ''Stygotantulus stocki'' at , to the Japanese spider crab with a l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prehistoric Crustacean Genera
Prehistory, also called pre-literary history, is the period of human history between the first known use of stone tools by hominins million years ago and the beginning of recorded history with the invention of writing systems. The use of symbols, marks, and images appears very early among humans, but the earliest known writing systems appeared years ago. It took thousands of years for writing systems to be widely adopted, with writing having spread to almost all cultures by the 19th century. The end of prehistory therefore came at different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. It is based on an old conception of history that without written records there could be no history. The most common conception today is that history is based on evidence, however the concept of prehistory hasn't been completely discarded. In the early Bronze Age, Sumer in Mesopotamia, the Indus Valley Civilis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
