Subfossil
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years old to 4.1 billion years old. Early edition, published online before print. The observation in the 19th century that certain fossils were associated with certain rock strata led to the recognition of a geological timescale and the relative ages of different fossils. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the absolute ...

Black Sea
The Black Sea is a marginal mediterranean sea of the Atlantic Ocean lying between Europe and Asia, east of the Balkans, south of the East European Plain, west of the Caucasus, and north of Anatolia. It is bounded by Bulgaria, Georgia, Romania, Russia, Turkey, and Ukraine. The Black Sea is supplied by major rivers, principally the Danube, Dnieper, and Don. Consequently, while six countries have a coastline on the sea, its drainage basin includes parts of 24 countries in Europe. The Black Sea covers (not including the Sea of Azov), has a maximum depth of , and a volume of . Most of its coasts ascend rapidly. These rises are the Pontic Mountains to the south, bar the southwest-facing peninsulas, the Caucasus Mountains to the east, and the Crimean Mountains to the mid-north. In the west, the coast is generally small floodplains below foothills such as the Strandzha; Cape Emine, a dwindling of the east end of the Balkan Mountains; and the Dobruja Plateau considerably farth ...

This list of non-marine molluscs of Germany is a list of the molluscs that live in Germany, except for the marine (saltwater) species. In other words, this list includes the land snails and slugs, the freshwater snails and the freshwater clams and mussels. There are 390 species (including subspecies) of molluscs living in the wild in Germany. In addition there is at least 1 gastropod species that lives only in greenhouses. There are ??? species of gastropods (69 species of freshwater gastropods, ??? species of land gastropods) and 36 species of bivalves living in the wild. There are 8 introduced species of gastropods (7 freshwater and 1 land species) and 1 species of non-indigenous bivalve living in the wild in Germany. That makes a total of 8 freshwater non-indigenous species of wild molluscs. ;Summary table of number of species There are only orders, families and species in the list.

Slovak Academy Of Sciences
The Slovak Academy of Sciences ( sk, Slovenská akadémia vied, or SAV) is the main scientific and research institution in Slovakia fostering basic and strategic basic research. It was founded in 1942, closed after World War II, and then reestablished in 1953. Its primary mission is to acquire new knowledge of nature, society and technology, specifically targeted at ensuring scientific basis for the advancement in Slovakia. It comprises 58 scientific institutes and 13 ancillary institutions. The SAV edits 44 scientific and scholarly journals and 100–120 monographs per annum. Moreover, 41 scientific and scholarly societies, which associate scientists and scholars from various disciplines, are affiliated with SAV. History The commencement of modern science in the 16th and 17th centuries resulted in the establishment of new institutions that supplemented classical universities and created a broader forum for fostering science communication. These institutions, which were buil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Baltic Region
The terms Baltic Sea Region, Baltic Rim countries (or simply the Baltic Rim), and the Baltic Sea countries/states refer to slightly different combinations of countries in the general area surrounding the Baltic Sea, mainly in Northern Europe. The term " Baltic states" refers specifically to one such grouping. Etymology The first to name it the ''Baltic Sea'' ( la, Mare Balticum) was 11th century German chronicler Adam of Bremen. Denotation Depending on the context the ''Baltic Sea Region'' might stand for: * The countries that have shorelines along the Baltic Sea: Denmark, Estonia, Finland, Germany, Latvia, Lithuania, Poland, Russia, and Sweden. * The group of countries that are members of the inter-governmental ''Baltic Assembly'' and ''Baltic Council of Ministers'', and generally referred to by the shorthand, Baltic states: Estonia, Latvia, and Lithuania. * Estonia, Latvia, Lithuania and Kaliningrad Oblast of Russia, exclaved from the remainder of Russia.«The Balt ...

Karl Theodor Menke
Karl Theodor Menke (13 September 1791 – 1861) was a German malacologist and balneologist who was a native of Bremen. He is remembered for his research on snails. Menke studied medicine at the University of Göttingen (with Promotion in 1814), and worked as a physician at the spa in Bad Pyrmont. In 1831 he was elected a member of the Academy of Sciences Leopoldina. In 1844 he founded the journal ''Zeitschrift für Malakozoologie'' (from 1854 titled ''Malakozoologische Blätter''). With Ludwig Karl Georg Pfeiffer (1805—1877), he was editor of the magazine. During his lifetime, Menke amassed a large collection of snail shells, which were purchased by dealer M.J. Landauer of Frankfurt after his death. The sea snail species; '' Cerithium menkei'' and '' Natica menkeana'' are named in honor of Menke. Also in 1843, '' Menkea'' a genus of flowering plants from Australia, belonging to the family Brassicaceae was published and named in his honour. Bibliography * Karl Theodor Menke ...

Mollusc
Mollusca is the second-largest phylum of invertebrate animals after the Arthropoda, the members of which are known as molluscs or mollusks (). Around 85,000 extant species of molluscs are recognized. The number of fossil species is estimated between 60,000 and 100,000 additional species. The proportion of undescribed species is very high. Many taxa remain poorly studied. Molluscs are the largest marine phylum, comprising about 23% of all the named marine organisms. Numerous molluscs also live in freshwater and terrestrial habitats. They are highly diverse, not just in size and anatomical structure, but also in behaviour and habitat. The phylum is typically divided into 7 or 8 taxonomic classes, of which two are entirely extinct. Cephalopod molluscs, such as squid, cuttlefish, and octopuses, are among the most neurologically advanced of all invertebrates—and either the giant squid or the colossal squid is the largest known invertebrate species.
