Hiodontidae
Hiodontidae, commonly called mooneyes, is a family of ray-finned fish with a single included genus ''Hiodon''. The genus comprise two living species native to North America and three to five extinct species recorded from Paleocene to Eocene age fossils. They are large-eyed, fork-tailed fish that superficially resemble shads. The vernacular name comes from the metallic shine of their eyes. The higher classification of the mooneyes is not yet fully established. Some sources have place them in their own order, Hiodontiformes, while others retain them in the order Osteoglossiformes. Species *''Hiodon alosoides'' (Rafinesque, 1819) The goldeye, ''Hiodon alosoides'', is widespread across eastern North America, and is notable for a conspicuous golden iris in the eyes. It prefers turbid slower-moving waters of lakes and rivers, where it feeds on a wide variety of organisms including insects, crustaceans, small fish, and mollusks. The fish has been reported up to in length. *†''H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hiodon Woodruffi
''Hiodon woodruffi'' is an extinct species of bony fish in the mooneye family, Hiodontidae. The species is known from fossils found in the early Eocene deposits of northern Washington state in the United States and late Eocene deposits in northwestern Montana. The species was first described as ''Eohiodon woodruffi''. ''H. woodruffi'' is one of two Eocene Okanagan Highlands mooneye species, and one of five fish identified in the Klondike Mountain Formation. Distribution and paleoenvironment ''Hiodon woodruffi'' fossils have been recovered from two locations in the Okanagan highlands, the Horsefly shale near Horsefly, British Columbia and the several exposures of the Klondike Mountain Formation in northern Ferry County, Washington. Both sites represent upland lake systems that were surrounded by a warm temperate ecosystem with nearby volcanism. The highlands likely had a mesic upper microthermal to lower mesothermal climate, in which winter temperatures rarely dropped low e ...

Hiodontiformes
Hiodontiformes is an order of ray-finned fish consisting of the two living species of the mooneye family, Hiodontidae, and three extinct genera. These are traditionally classified within the order Osteoglossiformes, a placement some authorities still follow. Fossil study of the extinct genus ''Yanbiania'' suggests that the hiodontids separated from other osteoglossomorphs early and thus may deserve a separate order.

Hiodon Alosoides
The goldeye (''Hiodon alosoides'') is a freshwater fish found in Canada and the northern United States. It is one of only two extant species in the family Hiodontidae, the other species being ''Hiodon tergisus''. The species name ''alosoides'' means shad-like. It is also called Winnipeg goldeye, western goldeye, yellow herring, toothed herring, shad mooneye, la Queche, weepicheesis, or ''laquaiche aux yeux d’or'' in French. Morphology Goldeyes are recognizable by their silver compressed body form and their large gold eyes. Their body appears to be a blue-green silver from above and a more white silver from below. They have two abdominal and pelvic fins as well as a dorsal on their back and an anal fin on their underside. The dorsal fin is positioned opposite or behind the origin of the anal fin. Goldeyes also have a fleshy keel that extends from the pectoral fins to the base of the anal fin. Their mouth is large and in the terminal position with a blunt round snout. The Go ...

Hiodon Tergisus
''Hiodon tergisus'', the mooneye, is a freshwater fish that is widespread across eastern North America. Anatomy and appearance ''H. tergisus'' is characterized by its silvery appearance, strongly compressed deep body, and keel that extends from its anal to pelvic fin.

They can be found as far north as the Hudson Bay and as far south as the Mississippi delta. They have been found as far west as central Alberta, Canada, and as far east as the western edge of North Carolina. Historically, mooneyes have been found in all of the Great Lakes, excluding Lake Superior.Hammerson, G. 2012 Hiodon Tergisus. NatureServe Explorer: ...

Klondike Mountain Formation
The Klondike Mountain Formation is an Early Eocene (Ypresian) geological formation located in the northeast central area of Washington state. The formation, named for the type location designated in 1962, Klondike Mountain north of Republic, Washington, is composed of volcanic rocks in the upper unit and volcanics plus lacustrine (lakebed) sedimentation in which a lagerstätte with exceptionally well-preserved plant and insect fossils has been found, along with fossil epithermal hot springs. The formation is the youngest in a group of formations which belong to the Challis Sequence rocks. The formation unconformably overlies rocks of the Eocene Sanpoil Volcanics and much older Triassic and Permian formations. The formation is bounded on its edges by a series of high-angle strike slip faults, which have contained the Klondike Mountain Formation in a series of graben structures, such as the Republic Graben. Public access to a fossiliferous outcrop at the north end of Republic is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Osteoglossiformes
Osteoglossiformes (Greek: "bony tongues") is a relatively primitive order of ray-finned fish that contains two sub-orders, the Osteoglossoidei and the Notopteroidei. All of at least 245 living species inhabit freshwater. They are found in South America, Africa, Australia and southern Asia, having first evolved in Gondwana before that continent broke up. In 2008 several new species of marine osteoglossiforms was described from the Danish Eocene Fur Formation dramatically increases the diversity of this group. This implies that the Osteoglossomorpha is not a primary freshwater fish group with the osteoglossiforms having a typical Gondwana distribution. The Gymnarchidae (the only species being ''Gymnarchus niloticus'', the African knifefish) and the Mormyridae are weakly electric fish able to sense their prey using electric fields. The mooneyes (Hiodontidae) are often classified here, but may also be placed in a separate order, Hiodontiformes. Members of the order are notable ...

Crustacean
Crustaceans (Crustacea, ) form a large, diverse arthropod taxon which includes such animals as decapods, seed shrimp, branchiopods, fish lice, krill, remipedes, isopods, barnacles, copepods, amphipods and mantis shrimp. The crustacean group can be treated as a subphylum under the clade Mandibulata. It is now well accepted that the hexapods emerged deep in the Crustacean group, with the completed group referred to as Pancrustacea. Some crustaceans (Remipedia, Cephalocarida, Branchiopoda) are more closely related to insects and the other hexapods than they are to certain other crustaceans. The 67,000 described species range in size from '' Stygotantulus stocki'' at , to the Japanese spider crab with a leg span of up to and a mass of . Like other arthropods, crustaceans have an exoskeleton, which they moult to grow. They are distinguished from other groups of arthropods, such as insects, myriapods and chelicerates, by the possession of biramous (two-parted) limbs, and by th ...

Late Eocene
The Eocene ( ) Epoch is a geological epoch that lasted from about 56 to 33.9 million years ago (mya). It is the second epoch of the Paleogene Period in the modern Cenozoic Era. The name ''Eocene'' comes from the Ancient Greek (''ēṓs'', "dawn") and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch. The Eocene spans the time from the end of the Paleocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by a brief period in which the concentration of the carbon isotope 13C in the atmosphere was exceptionally low in comparison with the more common isotope 12C. The end is set at a major extinction event called the ''Grande Coupure'' (the "Great Break" in continuity) or the Eocene–Oligocene extinction event, which may be related to the impact of one or more large bolides in Siberia and in what is now Chesapeake Bay. As with other geologic periods, the strata that define the start and end of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
