Acentrophryne is a genus of leftvents known from the eastern Pacific Ocean. Fossils of the type species, A. longidens, have been found in Late Miocene strata of Rosedale, California.
There are currently two recognized species in this genus: [2]
Gannets are seabirds comprising the genus Morus, in the family Sulidae, closely related to boobies. "Gannet" is derived from Old English ganot, ultimately from the same Old Germanic root as "gander". Morus is derived from Ancient Greek moros, "foolish", due to the lack of fear shown by breeding gannets and boobies, allowing them to be easily killed.
Goosefishes are anglerfishes in the family Lophiidae found in the Arctic, Atlantic, Indian, and Pacific Oceans, where they live on sandy and muddy bottoms of the continental shelf and continental slope, to depths of more than 1,000 m (3,300 ft). Like most other anglerfishes, they have a very large head with a large mouth that bears long, sharp, recurved teeth. Also like other anglerfishes, the first spine of the spinous dorsal fin has been modified as an angling apparatus (illicium) that bears a bulb-like or fleshy lure (esca).
Leftvents are small, deep-sea lophiiform fish comprising the family Linophrynidae distributed throughout tropical to subtropical waters of all oceans.
Peltosaurus is an extinct genus of anguid lizard from North America that lived from the Eocene to the Oligocene. Peltosaurus belongs to the anguid subfamily Glyptosaurinae. The type species Peltosaurus granulosus was named in 1873 by American paleontologist Edward Drinker Cope. Many additional species have been named, but most have been reassigned to different genera. For example, Peltosaurus piger, named in 1928, was reclassified as Odaxosaurus piger, and P. jepseni, named in 1942 from the Paleocene of Wyoming, but was later reclassified as Proxestops jepseni. In 1955 a new species, Peltosaurus macrodon, was named from the Eocene of California. Lizard bones from the Late Miocene of Nebraska were attributed to a new species of Peltosaurus called P. minimus in 1976, extending the fossil range of Peltosaurus and Glyptosaurinae into the Neogene. However, these bones were later referred to a genus of skinks called Eumeces, meaning that the fossil range of Peltosaurus and Glyptosaurinae does not go beyond the Paleogene.
Ornithosuchus is an extinct genus of pseudosuchians from the Late Triassic (Carnian) Lossiemouth Sandstone of Scotland. It was originally thought to be the ancestor to the carnosaurian dinosaurs. However, it is now known to be more closely related to crocodilians than to dinosaurs.
Frogfishes are any member of the anglerfish family Antennariidae, of the order Lophiiformes. Antennariids are known as anglerfish in Australia, where the term "frogfish" refers to members of the unrelated family Batrachoididae. Frogfishes are found in almost all tropical and subtropical oceans and seas around the world, the primary exception being the Mediterranean Sea.
Meleagridinae is a North American subfamily of birds in the family Phasianidae. It includes turkeys and their extinct relatives.
Scapanus is a genus of moles in the family Talpidae. They live in North America from west of the Rockies south to Baja California del Norte, and north to British Columbia, wherever conditions permit a mole population; that is to say, apart from the most sandy, rocky, or developed places. As they are one genus, they are very closely related, but as species, they rarely if ever interbreed successfully.
Euclastes is an extinct genus of sea turtles that survived the Cretaceous–Paleogene mass extinction. The genus was first named by Edward Drinker Cope in 1867, and contains three species. E. hutchisoni, was named in 2003 but has since been reassigned to the genus Pacifichelys, while E. coahuilaensis named in 2009 was reassigned as Mexichelys coahuilaensis in 2010.
Panopea is a genus of large marine bivalve molluscs or clams in the family Hiatellidae. There are 10 described species in Panopea. Many of them are known under the common name "geoduck".
Laytonia is an extinct genus of prehistoric halosaur that lived in deep water off the North American Pacific Coast from the Zemorrian Epoch until during the Upper Miocene subepoch, when tectonic uplift effectively destroyed the genus' habitat by making the deep water too shallow.
The Iron Canyon Site is a Miocene assemblage of vertebrate fossils located in Kern County, California within the Dove Spring Formation dating from ~23.03—5.33 Ma.
Theodore Wells Pietsch III is an American systematist and evolutionary biologist especially known for his studies of anglerfishes. Pietsch has described 72 species and 14 genera of fishes and published numerous scientific papers focusing on the relationships, evolutionary history, and functional morphology of teleosts, particularly deep-sea taxa. For this body of work, Pietsch was awarded the Robert H. Gibbs Jr. Memorial Award in Systematic Ichthyology by the American Society of Ichthyologists and Herpetologists in 2005. Pietsch has spent most of his career at the University of Washington in Seattle as a professor mentoring graduate students, teaching ichthyology to undergraduates, and curating the ichthyology collections of the UW Burke Museum of Natural History and Culture.
Pacifichelys is an extinct genus of sea turtle from the Middle Miocene of Peru and California. It was first named by James F. Parham and Nicholas D. Pyenson in 2010, and the type species is Pacifichelys urbinai from Peru. A second species, P. hutchisoni, was reassigned from the genus Euclastes. It is known from the Miocene of California. Like the living Ridley and loggerhead sea turtles, Pacifichelys was durophagous, consuming hard-shelled organisms with crushing jaws.
Thecachampsa is an extinct genus of tomistomine crocodylian. Fossils have been found from the eastern United States in deposits of late Oliogcene to Miocene age. Those named in the 19th century were distinguished primarily by the shape of their teeth, and have since been combined with T. antiquus. More recently erected species were reassigned from other tomistomine genera, although their assignment to Thecachampsa has since been questioned.
Borophryne apogon, the netdevil, or greedy seadevil, is a species of leftvent anglerfish known today from the waters of the eastern Pacific Ocean off the Central American coast. It is found at depths down to around 1,750 m (5,700 ft). This species grows to a length of 8.3 centimetres (3.3 in) TL. A fossil specimen of this species has been found in the Los Angeles Basin dating back to the Late Miocene, some eight million years ago.
Linophryne is a genus of leftvents, commonly called the "bearded seadevils."
The St. Marys Formation is a geologic formation in Maryland and Virginia, United States. It preserves fossils dating back to the Miocene Epoch of the Neogene period. It is the youngest Miocene formation present in the Calvert Cliffs and is part of the Chesapeake Group.
Linophryne indica, or headlight angler, is a leftvent anglerfish in the family Linophrynidae, found in the bathyal zone of the Pacific Ocean at depths below 1,000 m (3,300 ft). The female is significantly larger than the mature male. A fossil specimen of this species has been found in the Los Angeles Basin dating back to the Late Miocene, some eight million years ago.
Astroscopus, the electric stargazers, is a genus of stargazers, a type of percomorph fish from the family Uranoscopidae, part of the order Trachiniformes. The species in this genus are anatomically distinct Uranoscopids, being characterized by internal nares and being the only group of marine bony fish having organs which produce electricity which are derived from the extraocular muscles. They are found on the Atlantic and Pacific coasts of the Americas.
