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 d ...

Hemse
Hemse is a locality situated on the Swedish island of Gotland with 1,700 inhabitants in 2014. It is the second largest locality (after Visby) on the island. Hemse is the main center of population in the southern part of the island, and it is known for its markets. Hemse is also the name of the larger populated area, socken (not to be confused with parish). It comprises the same area as the administrative Hemse District, established on 1January 2016. Geography Hemse is the name of the locality surrounding the medieval Hemse Church, sometimes referred to as ''Hemse kyrkby''. It is also the name of the socken as well as the district. Hemse is situated in the central part of southern Gotland. , Hemse Church belongs to Alva-Hemse-Rone parish in Sudrets pastorat, along with the churches in Alva and Rone. One of the asteroids in the asteroid belt, 10124 Hemse, is named after this place. History Hemse stave church, the best-preserved remnants of a stave church from present-day S ...

Royal Swedish Academy Of Sciences
The Royal Swedish Academy of Sciences ( sv, Kungliga Vetenskapsakademien) is one of the royal academies of Sweden. Founded on 2 June 1739, it is an independent, non-governmental scientific organization that takes special responsibility for promoting natural sciences and mathematics and strengthening their influence in society, whilst endeavouring to promote the exchange of ideas between various disciplines. The goals of the academy are: * to be a forum where researchers meet across subject boundaries, * to offer a unique environment for research, * to provide support to younger researchers, * to reward outstanding research efforts, * to communicate internationally among scientists, * to advance the case for science within society and to influence research policy priorities * to stimulate interest in mathematics and science in school, and * to disseminate and popularize scientific information in various forms. Every year, the academy awards the Nobel Prizes in physics and chem ...

Body Whorl
The body whorl is part of the morphology of the shell in those gastropod mollusks that possess a coiled shell. The term is also sometimes used in a similar way to describe the shell of a cephalopod mollusk. In gastropods In gastropods, the body whorl, or last whorl, is the most recently formed and largest whorl (or revolution) of a spiral or helical shell, terminating in the aperture. It is called the "body whorl" because most of the body of the soft parts of the animal fits into this whorl. The proportional size of the body whorl in gastropod shells differs greatly according to the actual shell morphology. For shells in which the rate of whorl expansion of each revolution around the axis is very high, the aperture and the body whorl are large, and the shell tends to be low spired. The shell of the abalone is a good example of this kind of shell. The opposite tendency can sometimes create a high spire with very little whorl increase per revolution. In these instances ...

Filter Feeder
Filter feeders are a sub-group of suspension feeding animals that feed by straining suspended matter and food particles from water, typically by passing the water over a specialized filtering structure. Some animals that use this method of feeding are clams, krill, sponges, baleen whales, and many fish (including some sharks). Some birds, such as flamingos and certain species of duck, are also filter feeders. Filter feeders can play an important role in clarifying water, and are therefore considered ecosystem engineers. They are also important in bioaccumulation and, as a result, as indicator organisms. Fish Most forage fish are filter feeders. For example, the Atlantic menhaden, a type of herring, lives on plankton caught in midwater. Adult menhaden can filter up to four gallons of water a minute and play an important role in clarifying ocean water. They are also a natural check to the deadly red tide. Extensive article on the role of menhaden in the ecosystem and possibl ...

Fauna
Fauna is all of the animal life present in a particular region or time. The corresponding term for plants is ''flora'', and for fungi, it is '' funga''. Flora, fauna, funga and other forms of life are collectively referred to as ''biota''. Zoologists and paleontologists use ''fauna'' to refer to a typical collection of animals found in a specific time or place, e.g. the " Sonoran Desert fauna" or the " Burgess Shale fauna". Paleontologists sometimes refer to a sequence of faunal stages, which is a series of rocks all containing similar fossils. The study of animals of a particular region is called faunistics. Etymology '' Fauna'' comes from the name Fauna, a Roman goddess of earth and fertility, the Roman god Faunus, and the related forest spirits called Fauns. All three words are cognates of the name of the Greek god Pan, and ''panis'' is the Greek equivalent of fauna. ''Fauna'' is also the word for a book that catalogues the animals in such a manner. The term was fir ...

Fardhem Church
Fardhem Church ( sv, Fardhems kyrka) is a medieval church in Fardhem on the Swedish island of Gotland. The present-day church may have been preceded by a stave church; the current church is one of the most well-preserved Romanesque churches on Gotland, built in stages from the 12th to 13th century. It belongs to the Church of Sweden and lies in the Diocese of Visby. History According to the Gutasaga, one of the earliest churches on Gotland was built in Fardhem. If so, this was a stave church of which nothing remains today. Early graves found in the area however indicate that there might well have been a wooden church at the site of the presently visible one early on. The church seen today is also of considerable age. It is a Romanesque building, erected in stages from the end of the 12th century to the second quarter of the 13th century. Only the vestry is later, added in 1871-72 and designed by Axel Haig (known in Sweden by his original name Axel Herman Hägg. Architecture The e ...
