Aeneator (gastropod)
''Aeneator'' is a genus of sea snails, marine gastropod molluscs in the family Buccinidae, the true whelks. Description ''Aeneator'' is a genus of small to medium sized marine snails. Powell A. W. B., ''New Zealand Mollusca'', William Collins Publishers Ltd, Auckland, New Zealand 1979 Large shells and fossils of ''Aeneator'' can sometimes be confused with those of ''Penion''. Distribution Most extant species of ''Aeneator'' are found around New Zealand, Chile, and Antarctica. Stilwell, J.D., Zinsmeister, W.J. 1992.

Miocene
The Miocene ( ) is the first geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene is preceded by the Oligocene and is followed by the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by a single distinct global event but consist rather of regionally defined boundaries between the warmer Oligocene and the cooler Pliocene Epoch. During the Early Miocene, the Arabian Peninsula collided with Eurasia, severing the connection between the Mediterranean and Indian Ocean, and allowing a faunal interchange to occur between Eurasia and Africa, including the dispersal of proboscideans into Eurasia. During the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. The gastropods ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Fleming (ornithologist)
Sir Charles Alexander Fleming (9 September 1916 – 11 September 1987) was a New Zealand geologist, ornithologist, molluscan palaeontologist and environmentalist. He spent the last twenty years of his life studying the evolution and systematics of New Zealand cicadas. Fleming graduated from the University of Auckland in 1952 with a doctoral thesis on the geology of Whanganui. He was active in the Save Manapouri Campaign, was a spokesperson for Native Forest Action Council and the Royal Forest and Bird Protection Society of New Zealand. He was elected to the American Philosophical Society in 1973. In 1974 he was elected a Fellow of the Royal Australasian Ornithologists Union. In 1988 the Royal Society of New Zealand established the Charles Fleming Award which is awarded to individuals who have achieved distinction in the protection, maintenance, management, improvement, or understanding of the environment. In 1997, Trevor H. Worthy commemorated Charles Fleming in the spec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aeneator Antorbitus
An ''aeneator'' ( lat, aēneātor or ) was a specialized player of wind instruments who was attached to a Roman military unit. The word comes from Latin ''aēneus'' or ''ahēneus'', "brazen", from ''aes'', "copper alloy". While the size of individual Roman military units may have varied, they made extensive use of both acoustical and visual signaling in communications and each had an assigned banner bearer (''vexillarius'') and at least one ''aeneator''. A variety of instruments were used by ''aeneatores'', including the ''buccina'', '' cornu'', ''tuba'', and ''lituus''. In addition to their roles in the Roman army, ''aeneatores'' were also used for processionals and games, particularly in marching home from war. Categories of ''aeneatores'' ''Aeneatores'' who blew a ''buccina'' (a ''C''-shaped horn made of bronze or silver or animal horn) were known as ''buccinators''; those who blew a ''cornu'' (a ''G''-shaped horn made of brass) were known as '' cornicines''; those who blew a ...

Extinction
Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dodos, m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
