Acton Lake
Hueston Woods State Park is a state park located in Butler and Preble counties of the U.S. state of Ohio, about five miles (8 km) northeast of Oxford in the southwestern part of the state. The park lies in Oxford Township, Butler County, and Israel Township, Preble County. It has nearly , including a man-made lake of . The park's beech-maple climax forest has been designated a National Natural Landmark. History The state bought the land in 1941, but the park did not open until 1957. The state used the land initially as a prison camp. In 1956, Four Mile Creek was dammed to form Acton Lake, named for Clyde Acton, the member of the Ohio General Assembly who persuaded the legislature to buy the property. Hueston Woods was designated as a National Natural Landmark by the National Park Service in 1967. The park was temporarily named after former Cincinnati Bengals player Ickey Woods prior to Super Bowl LVI. Features "The limestone and shale bedrock of the Hueston Woods area ...

Butler County, Ohio
Butler County is a county located in the southwestern part of the U.S. state of Ohio. As of the 2020 census, the population was 390,357. Its county seat is Hamilton. It is named for General Richard Butler, who died in 1791 during St. Clair's Defeat. Located along the Great Miami River, it is also home to Miami University, a public university founded in 1809. Butler County is part of the Cincinnati, OH-KY-IN Metropolitan Statistical Area. The majority of the county is in District 52 of the State House. History Successive cultures of ancient Indigenous peoples of the Americas occupied areas of the county. They built large earthworks, seven of which were still standing and recorded by a Smithsonian survey. Early French explorers likely passed through the area along the Miami River. The gravesites of David and Margaret Gregory indicate they were some of the first white settlers in the area in Liberty Township. White settlers began moving into the area in larger numbers after t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cincinnati Bengals
The Cincinnati Bengals are a professional American football team based in Cincinnati. The Bengals compete in the National Football League (NFL) as a member club of the league's American Football Conference (AFC) AFC North, North division. The club's home games are held in downtown Cincinnati at Paycor Stadium, Paul Brown Stadium. Former Cleveland Browns head coach Paul Brown began planning for the creation of the Bengals franchise in 1965, and Cincinnati's city council approved the construction of Riverfront Stadium in 1966. Finally, in 1967, the Bengals were founded when a group headed by Brown received franchise approval by the American Football League (AFL) on May 23, 1967, and they began play in the 1968 season. Brown was the Bengals' head coach from their inception to . After being dismissed as the Browns' head coach by Art Modell (who had purchased a majority interest in the team in ) in January , Brown had shown interest in establishing another NFL franchise in Ohio and l ...

North American Beaver
The North American beaver (''Castor canadensis'') is one of two Extant taxon, extant beaver species, along with the Eurasian beaver (''Castor fiber''). It is native to North America and introduced in South America (Patagonia) and Europe (primarily Finland and Karelia). In Canada and the United States, the species is often referred to simply as "beaver", though this causes some confusion because another distantly related rodent, ''Aplodontia rufa'', is often called the "mountain beaver". Other vernacular names, including American beaver and Canadian beaver, distinguish this species from the other Extant taxon, extant beaver species, ''Castor fiber'', which is native to Eurasia. The North American beaver is one of the official national wildlife of Canada symbols and is the official state mammal of Oregon and New York (state), New York. Taxonomy Evolution The first fossil records of beaver are 10 to 12 million years old in Germany, and they are thought to have migrated to North Amer ...

Historic House Museum
A historic house museum is a house of historic significance that has been transformed into a museum. Historic furnishings may be displayed in a way that reflects their original placement and usage in a home. Historic house museums are held to a variety of standards, including those of the International Council of Museums. Houses are transformed into museums for a number of different reasons. For example, the homes of famous writers are frequently turned into writer's home museums to support literary tourism. About Historic house museums are sometimes known as a "memory museum", which is a term used to suggest that the museum contains a collection of the traces of memory of the people who once lived there. It is often made up of the inhabitants' belongings and objects – this approach is mostly concerned with authenticity. Some museums are organised around the person who lived there or the social role the house had. Other historic house museums may be partially or completely re ...

Mollusc Shell
The mollusc (or molluskOften spelled mollusk shell in the USA; the spelling "mollusc" are preferred by ) shell is typically a calcareous exoskeleton which encloses, supports and protects the soft parts of an animal in the phylum Mollusca, which includes snails, clams, tusk shells, and several other classes. Not all shelled molluscs live in the sea; many live on the land and in freshwater. The ancestral mollusc is thought to have had a shell, but this has subsequently been lost or reduced on some families, such as the squid, octopus, and some smaller groups such as the caudofoveata and solenogastres. Today, over 100,000 living species bear a shell; there is some dispute as to whether these shell-bearing molluscs form a monophyletic group (conchifera) or whether shell-less molluscs are interleaved into their family tree. Malacology, the scientific study of molluscs as living organisms, has a branch devoted to the study of shells, and this is called conchology—although these te ...

Trilobite
Trilobites (; meaning "three lobes") are extinct marine arthropods that form the class Trilobita. Trilobites form one of the earliest-known groups of arthropods. The first appearance of trilobites in the fossil record defines the base of the Atdabanian stage of the Early Cambrian period () and they flourished throughout the lower Paleozoic before slipping into a long decline, when, during the Devonian, all trilobite orders except the Proetida died out. The last extant trilobites finally disappeared in the mass extinction at the end of the Permian about 252 million years ago. Trilobites were among the most successful of all early animals, existing in oceans for almost 270 million years, with over 22,000 species having been described. By the time trilobites first appeared in the fossil record, they were already highly diversified and geographically dispersed. Because trilobites had wide diversity and an easily fossilized exoskeleton, they left an extensive fossil record. The stu ...

Crinoid
Crinoids are marine animals that make up the class Crinoidea. Crinoids that are attached to the sea bottom by a stalk in their adult form are commonly called sea lilies, while the unstalked forms are called feather stars or comatulids, which are members of the largest crinoid order, Comatulida. Crinoids are echinoderms in the phylum Echinodermata, which also includes the starfish, brittle stars, sea urchins and sea cucumbers. They live in both shallow water and in depths as great as . Adult crinoids are characterised by having the mouth located on the upper surface. This is surrounded by feeding arms, and is linked to a U-shaped gut, with the anus being located on the oral disc near the mouth. Although the basic echinoderm pattern of fivefold symmetry can be recognised, in most crinoids the five arms are subdivided into ten or more. These have feathery pinnules and are spread wide to gather planktonic particles from the water. At some stage in their lives, most crinoids have ...

Gastropoda
The gastropods (), commonly known as snails and slugs, belong to a large taxonomic class of invertebrates within the phylum Mollusca called Gastropoda (). This class comprises snails and slugs from saltwater, from freshwater, and from land. There are many thousands of species of sea snails and slugs, as well as freshwater snails, freshwater limpets, and land snails and slugs. The class Gastropoda contains a vast total of named species, second only to the insects in overall number. The fossil history of this class goes back to the Late Cambrian. , 721 families of gastropods are known, of which 245 are extinct and appear only in the fossil record, while 476 are currently extant with or without a fossil record. Gastropoda (previously known as univalves and sometimes spelled "Gasteropoda") are a major part of the phylum Mollusca, and are the most highly diversified class in the phylum, with 65,000 to 80,000 living snail and slug species.

Cephalopod
A cephalopod is any member of the molluscan class Cephalopoda (Greek plural , ; "head-feet") such as a squid, octopus, cuttlefish, or nautilus. These exclusively marine animals are characterized by bilateral body symmetry, a prominent head, and a set of arms or tentacles (muscular hydrostats) modified from the primitive molluscan foot. Fishers sometimes call cephalopods "inkfish", referring to their common ability to squirt ink. The study of cephalopods is a branch of malacology known as teuthology. Cephalopods became dominant during the Ordovician period, represented by primitive nautiloids. The class now contains two, only distantly related, extant subclasses: Coleoidea, which includes octopuses, squid, and cuttlefish; and Nautiloidea, represented by ''Nautilus'' and ''Allonautilus''. In the Coleoidea, the molluscan shell has been internalized or is absent, whereas in the Nautiloidea, the external shell remains. About 800 living species of cephalopods have been ident ...

Horn Coral
The rugosa, also called the tetracorallia or horn coral, are an extinct order of solitary and colonial corals that were abundant in Middle Ordovician to Late Permian seas. Solitary rugosans (e.g., '' Caninia'', '' Lophophyllidium'', '' Neozaphrentis'', '' Streptelasma'') are often referred to as horn corals because of a unique horn-shaped chamber with a wrinkled, or rugose, wall. Some solitary rugosans reached nearly a meter in length. However, some species of rugose corals could form large colonies (e.g., ''Lithostrotion''). When radiating septa were present, they were usually in multiples of four, hence ''Tetracoralla'' in contrast to modern '' Hexacoralla'', colonial polyps generally with sixfold symmetry. Rugose corals have a skeleton made of calcite that is often fossilized. Like modern corals (Scleractinia), rugose corals were invariably benthic, living on the sea floor or in a reef-framework. Some symbiotic rugose corals were endobionts of Stromatoporoidea, especially ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pelecypods
Bivalvia (), in previous centuries referred to as the Lamellibranchiata and Pelecypoda, is a class of marine and freshwater molluscs that have laterally compressed bodies enclosed by a shell consisting of two hinged parts. As a group, bivalves have no head and they lack some usual molluscan organs, like the radula and the odontophore. They include the clams, oysters, cockles, mussels, scallops, and numerous other families that live in saltwater, as well as a number of families that live in freshwater. The majority are filter feeders. The gills have evolved into ctenidia, specialised organs for feeding and breathing. Most bivalves bury themselves in sediment, where they are relatively safe from predation. Others lie on the sea floor or attach themselves to rocks or other hard surfaces. Some bivalves, such as the scallops and file shells, can swim. The shipworms bore into wood, clay, or stone and live inside these substances. The shell of a bivalve is composed of calcium c ...

Evolution Of Brachiopods
The origin of the brachiopods is uncertain; they either arose from reduction of a multi-plated tubular organism, or from the folding of a slug-like organism with a protective shell on either end. Since their Cambrian origin, the phylum rose to a Palaeozoic dominance, but dwindled during the Mesozoic. Origins Brachiopod fold hypothesis The long-standing hypothesis of brachiopod origins, which has recently come under fire, suggests that the brachiopods arose by the folding of a ''Halkieria''-like organism, which bore two protective shells at either end of a scaled body. For a summary, see The tannuolinids were thought to represent an intermediate form, although the fact that they do not, as thought, possess a scleritome means that this is now considered unlikely. Under this hypothesis, the Phoronid worms share a similar evolutionary history; molecular data also appear to indicate their membership of Brachiopoda. Under the Brachiopod Fold Hypothesis, the "dorsal" and "ven ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
