Windom Shale Member
The Windom shale or Windom member is a member of the Moscow formation in New York. It preserves fossils going back to the Givetian stage of the middle Devonian. The Windom shale is widely known for its high quality trilobite fossils. History Early Study One of the first people who may have described the scientific importance of the Windom was Jacob Green. In his book ''A monograph of the trilobites of North America: with coloured models of the species'', he mentions an abundance of “'' Calymene bufo''” in similar conditions to that of the Windom. Later on in 1935, David M. Delo’s “Revision of the Phacopid trilobites” would name the genus ''Greenops'' in honor of Jacob Green’s work. In 1840, the geologist Lardner Vanuxem first described the “ Hamilton Formation” in Hamilton, New York. The American paleontologist James Hall, would be very influential in early scientific examination of the Hamilton group. American geologist and malacologist, Timothy Abbott Con ...

Eldredgeops Rana
''Eldredgeops rana'' (formerly ''Phacops rana'') is a species of trilobite from the middle Devonian period. Their fossils are found chiefly in the northeastern United States, and southwestern Ontario. Because of its abundance and popularity with collectors, ''Eldredgeops rana'' was designated the Pennsylvania state fossil by the state's General Assembly on December 5, 1988. Description ''Eldredgeops rana'' can be recognized by its large eyes (which remind some observers of a frog's eyes—the specific name ''rana'' is a reference to a common frog), its fairly large size (up to 6 inches long), and its habit of rolling up into a ball like a pill bug ("volvation"). In order to protect themselves from predators, ''Eldredgeops rana'' would roll into a ball with its hard exoskeleton on the outside as protection. Many other trilobites possessed the same ability, but ''Eldredgeops rana'' nearly perfected it. The slightest amount of sediment would trigger their senses, and ''El ...

James Hall (paleontologist)
James Hall Jr. (September 12, 1811 – August 7, 1898) was an American geologist and paleontologist. He was a noted authority on stratigraphy and had an influential role in the development of paleontology in the United States. Early life James Hall was born in Hingham, Massachusetts, the oldest of four children. His parents, James Hall Sr. and Sousanna Dourdain Hall, had emigrated from England two years earlier. Hall developed an early interest in science and enrolled in Rensselaer Polytechnic Institute, a recently established college that emphasized student participation and focused on science. He was a student of Amos Eaton and Ebenezer Emmons, both notable geologists. Hall graduated with honors in 1832, received his master's degree in 1833, and remained at Rensselaer to teach chemistry and later geology. In 1836 a multi-year survey was established to collect information on the geology and natural history of New York. For purposes of the survey, the state was divided into f ...

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 ...

Rugosa
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 ...

Catskill Delta
The Devonian Catskill Formation or the Catskill Clastic wedge is a unit of mostly terrestrial sedimentary rock found in Pennsylvania and New York. Minor marine layers exist in this thick rock unit (up to ). It is equivalent to the Hampshire Formation of Maryland, West Virginia, and Virginia. The Catskill is the largest bedrock unit of the Upper Devonian in northeast Pennsylvania and the Catskill region of New York, from which its name is derived. The Pocono Mountains of Pennsylvania are largely underlain by this unit as well. The rocks of the Catskill are predominantly red sandstone indicating a large scale terrestrial deposition during the Acadian orogeny. Many beds are cyclical in nature, preserving the record of a dynamic environment during its approximately 20 million years of deposition. Depositional environment During the Devonian period, the Catskill Delta was formed by a series of river deltas and otherwise marshy terrain. This terrain was sandwiched between the e ...

Swamps
A swamp is a forested wetland.Keddy, P.A. 2010. Wetland Ecology: Principles and Conservation (2nd edition). Cambridge University Press, Cambridge, UK. 497 p. Swamps are considered to be transition zones because both land and water play a role in creating this environment. Swamps vary in size and are located all around the world. The water of a swamp may be fresh water, brackish water, or seawater. Freshwater swamps form along large rivers or lakes where they are critically dependent upon rainwater and seasonal flooding to maintain natural water level fluctuations.Hughes, F.M.R. (ed.). 2003. The Flooded Forest: Guidance for policy makers and river managers in Europe on the restoration of floodplain forests. FLOBAR2, Department of Geography, University of Cambridge, Cambridge, UK. 96 p. Saltwater swamps are found along tropical and subtropical coastlines. Some swamps have hammock (ecology), hammocks, or dry-land protrusions, covered by aquatic vegetation, or vegetation that tolerates ...

Rivers
A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases, a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as creek, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague. Rivers are part of the water cycle. Water generally collects in a river from precipitation through a drainage basin from surface runoff and other sources such as groundwater recharge, springs, a ...

Hamburg, New York
Hamburg is a town in Erie County, New York, United States. As of the 2010 census, the town had a population of 56,936. It is named after the city of Hamburg, Germany. The town is on the western border of the county and is south of Buffalo. Hamburg is one of the Southtowns in Erie County. The villages of Hamburg and Blasdell are in the town. History Historical evidence shows the area was settled originally by the Erie people. Around 1805 the settlement was known as "Barkerville", named after Zenas Barker, the postmaster. The earliest settlers were Nathaniel Titus and Dr. Ruth Belden in 1804, and the first landowner in the area was John Cummings, who built the first grist mill in 1806. The town of Hamburg was formed by government decree on March 20, 1812, from the (now defunct) town of Willink. The first town meeting took place on April 7, 1812, at Jacob Wright's tavern at Wright's Corners, which was renamed Abbott's Corners, and now Armor. One of the early noted activi ...
