Frodospira Cochleata
''Frodospira cochleata'' is a species of extinct sea snail in the family Lophospiridae. Fossil specimens from 422.9 and 421.3 million years ago have been found in Sweden at Grogarnsberget, Hemse, and Sandarve kulle, in a hill about a kilometer north of Fardhem Church. A species of epifaunal filter feeder, it had a slender, turriculate shell consisting of twelve to thirteen whorls A whorl ( or ) is an individual circle, oval, volution or equivalent in a whorled pattern, which consists of a spiral or multiple concentric objects (including circles, ovals and arcs).

Silurian
The Silurian ( ) is a geologic period and system spanning 24.6 million years from the end of the Ordovician Period, at million years ago ( Mya), to the beginning of the Devonian Period, Mya. The Silurian is the shortest period of the Paleozoic Era. As with other geologic periods, the rock beds that define the period's start and end are well identified, but the exact dates are uncertain by a few million years. The base of the Silurian is set at a series of major Ordovician–Silurian extinction events when up to 60% of marine genera were wiped out. One important event in this period was the initial establishment of terrestrial life in what is known as the Silurian-Devonian Terrestrial Revolution: vascular plants emerged from more primitive land plants, dikaryan fungi started expanding and diversifying along with glomeromycotan fungi, and three groups of arthropods (myriapods, arachnids and hexapods) became fully terrestrialized. A significant evolutionary milestone during ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mollusk
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.

Fossil Taxa Described In 1999
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 abso ...

Gustaf Lindström
Gustaf Lindström (27 August 1829 – 16 May 1901) was a Sweden, Swedish paleontologist. He was born in Visby on Gotland. In 1848 he entered Uppsala University, and in 1854 he took his doctor's degree. Having attended a course of lectures in Stockholm by Sven Lovén, he became interested in the zoology of the Baltic Sea, Baltic, and published several papers on the invertebrate fauna (animals), fauna, and subsequently on the fishes. In 1856 he became a school teacher, and in 1858 a master in the grammar school at Visby. His leisure was devoted to researches on the fossils of the Silurian rocks of Gotland, including the corals, brachiopods, gastropods including pteropods, cephalopods and Crustacea. He described also remains of the fish ''Cyathaspis'' from Wenlock Beds in Gotland, with Tamerlan Thorell, a scorpion ''Palaeaphonus'' from Ludlow Beds at Wisby. He determined the true nature of the operculated coral. He was awarded the Murchison Medal by the Geological Society of Lon ...

Fossilworks
Fossilworks is a portal which provides query, download, and analysis tools to facilitate access to the Paleobiology Database The Paleobiology Database is an online resource for information on the distribution and classification of fossil animals, plants, and microorganisms. History The Paleobiology Database (PBDB) originated in the NCEAS-funded Phanerozoic Marine Pale ..., a large relational database assembled by hundreds of paleontologists from around the world.

The Lord Of The Rings
''The Lord of the Rings'' is an epic high-fantasy novel by English author and scholar J. R. R. Tolkien. Set in Middle-earth, intended to be Earth at some time in the distant past, the story began as a sequel to Tolkien's 1937 children's book ''The Hobbit'', but eventually developed into a much larger work. Written in stages between 1937 and 1949, ''The Lord of the Rings'' is one of the best-selling books ever written, with over 150 million copies sold. The title refers to the story's main antagonist, the Dark Lord Sauron, who, in an earlier age, created the One Ring to rule the other Rings of Power given to Men, Dwarves, and Elves, in his campaign to conquer all of Middle-earth. From homely beginnings in the Shire, a hobbit land reminiscent of the English countryside, the story ranges across Middle-earth, following the quest to destroy the One Ring mainly through the eyes of the hobbits Frodo, Sam, Merry and Pippin. Although often called a trilogy, the work was intende ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frodo Baggins
Frodo Baggins is a fictional character in J. R. R. Tolkien's writings, and one of the protagonists in ''The Lord of the Rings''. Frodo is a hobbit of the Shire who inherits the One Ring from his cousin Bilbo Baggins, described familiarly as "uncle", and undertakes the quest to destroy it in the fires of Mount Doom in Mordor. He is mentioned in Tolkien's posthumously published works, ''The Silmarillion'' and ''Unfinished Tales''. Frodo is repeatedly wounded during the quest, and becomes increasingly burdened by the Ring as it nears Mordor. He changes, too, growing in understanding and compassion, and avoiding violence. On his return to the Shire, he is unable to settle back into ordinary life; two years after the Ring's destruction, he is allowed to take ship to the earthly paradise of Valinor. Frodo's name comes from the Old English name '' Fróda'', meaning "wise by experience". Commentators have written that he combines courage, selflessness, and fidelity, and that as a goo ...
