Pantosteus Nebuliferus
''Pantosteus'', the mountain suckers, is a genus of North American freshwater ray-finned fish in the family Catostomidae. Long treated as a subgenus of ''Catostomus'', phylogenetic evidence has found them to a form a monophyletic group that diverged from other members of ''Catostomus'' during the Miocene, and they are thus treated better as a distinct genus. They are native to mountainous regions of western North America, from southern Canada to north-central Mexico. They are primarily found in the Interior West, where they are known from the Black Hills, Rocky Mountains,parts of the Sierra Madre Occidental, much of the Great Basin, and parts of the Cascade Range. However, a single isolated species (the Santa Ana sucker) is found west of the Cascades, in the San Gabriel Mountains. ''Pantosteus'' species tend to be smaller than those in ''Catostomus''. They inhabit cool, fast-flowing streams located in high-elevation environments. Taxonomy The following species are placed in t ...

Middle Miocene
The Middle Miocene is a sub-epoch of the Miocene epoch (geology), epoch made up of two Stage (stratigraphy), stages: the Langhian and Serravallian stages. The Middle Miocene is preceded by the Early Miocene. The sub-epoch lasted from 15.97 ± 0.05 Ma (million years ago) to 11.608 ± 0.005 Ma. During this period, a sharp drop in global temperatures took place. This event is known as the Middle Miocene disruption, Middle Miocene Climatic Transition. For the purpose of establishing European land mammal ages, this sub-epoch is equivalent to the Astaracian age.

Samuel Garman
Samuel Walton Garman (June 5, 1843 – September 30, 1927), or "Garmann" as he sometimes styled himself, was an American naturalist and zoologist. He became noted as an ichthyologist and herpetologist. Biography Garman was born in Indiana County, Pennsylvania, on 5 June 1843. In 1868 he joined an expedition to the American West with John Wesley Powell. He graduated from the Illinois State Normal University in 1870, and for the following year was principal of the Mississippi State Normal School. In 1871, he became professor of natural sciences in Ferry Hall Seminary, Lake Forest, Illinois, and a year later became a special pupil of Louis Agassiz. He was a friend and regular correspondent of the naturalist Edward Drinker Cope, and in 1872 accompanied him on a fossil hunting trip to Wyoming. In 1870 he became assistant director of herpetology and ichthyology at Harvard's Museum of Comparative Zoology. His work was mostly in the classification of fish, especially sharks, but ...

Pantosteus Discobolus
The bluehead sucker (''Pantosteus discobolus'') is a species of freshwater cypriniform fish endemic to the intermountain Western US. Formerly placed in the genus ''Catostomus'', it is now placed in the genus ''Pantosteus''. Description The bluehead sucker is the largest of all Arizona endemic suckers, reaching lengths over 11.8 in. Their colors are very similar to the desert sucker, with dark green or dark silvery top portions and light yellow bottoms. The bluehead has the largest lips of any sucker and has tiny papillae on the lower lip. This is also the only species with the absence of an inguinal process, just behind the pectoral fins, distinguishing it from the other eight suckers. The lower lip is slightly notched at the midline, with lateral line scales in large numbers that range from 70 to 100. They have 7 to 9 dorsal fin rays and a smaller number of caudal fin rays. During breeding, the males obtain a blue patch on the top of their large heads, and the lower ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Charles Frédéric Girard
Charles Frédéric Girard (; 8 March 1822 – 29 January 1895) was a French biologist specializing in ichthyology and herpetology. Biography Girard was born on 8 March 1822 in Mulhouse, France. He studied at the College of Neuchâtel, Switzerland, as a student of Louis Agassiz. In 1847, he accompanied Agassiz as his assistant to Harvard University. Three years later, Spencer Fullerton Baird called him to the Smithsonian Institution to work on its growing collection of North American reptiles, amphibians and fishes. He worked at the museum for the next ten years and published numerous papers, many in collaboration with Baird. In 1854, he was naturalized as a U.S. citizen. Besides his work at the Smithsonian, he managed to earn an M.D. from Georgetown University in Washington, D.C. in 1856. In 1859 he returned to France and was awarded the Cuvier Prize by the Institute of France for his work on the North American reptiles and fishes two years later. When the American Civil Wa ...
