Carcharodon is a genus of sharks within the family Lamnidae, colloquially called the "white sharks." The only extant member is the great white shark. The extant species was preceded by a number of fossil (extinct) species including C. hubbelli and C. hastalis. The first appearance of the genus may have been as early as the Early Miocene or Late Oligocene.
The stargazers are a family, Uranoscopidae, of perciform fish that have eyes on top of their heads. The family includes about 51 species in eight genera, all marine and found worldwide in shallow and deep saltwaters.
Calvert Cliffs State Park is a public recreation area in Lusby, Calvert County, Maryland, that protects a portion of the cliffs that extend for 24 miles along the eastern flank of the Calvert Peninsula on the west side of Chesapeake Bay from Chesapeake Beach southward to Drum Point. The state park is known for the abundance of mainly Middle Miocene sub-epoch fossils that can be found on the shoreline.
Rachycentron is the only known member genus of the family Rachycentridae. The genus contains a single living species, the cobia, and the Late Miocene fossil species Rachycentron stremphaencus from Maryland.
Trachiniformes is an order of percomorph bony fish, whose contents are traditionally pllaced in suborder Trachinoidei of Perciformes.
Uranoscopus is a genus of stargazer fish from the family Uranoscopidae. The name Uranoscopus is from the Greek, ouranos, "sky" and skopein, "to watch".
The Atlantic stargazer is a marine, subtropical fish of family Uranoscopidae. Its body is suited for living on the sea floor, and is one of few fish capable of bioelectrogenesis, or the ability to generate an electric charge.
Astroscopus countermani is an extinct species of stargazer described from a cranium found in Tortonian deposits of the Calvert Cliffs of what is now Maryland. A. countermani is very similar to its living relatives.
Lopholatilus is a small genus of tilefishes native to the western Atlantic Ocean.
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.
Lopholatilus ereborensis is an extinct species of tilefish found in formations at Calvert Cliffs State Park in Lusby, Maryland. The species lived in the Salisbury Embayment in the Western North Atlantic during the Miocene era, 16 million years ago. The species is believed to have dug long, funnel-shaped vertical burrows in the continental shelf, the collapse of which may account for the remarkable preservation of the fossils. The species measured 18 inches (46 cm) long. The name is derived from "Erebor", the Elvish name for the Lonely Mountain from J.R.R. Tolkien's The Hobbit.
The southern stargazer is a species of marine fish in the family Uranoscopidae and genus Astroscopus. They are native to the United States.
Lophocetus is an extinct genus of dolphin belonging to the clade Delphinida that is known from late Miocene (Tortonian) marine deposits in California and Maryland. Although usually placed in Kentriodontidae, recent studies have found it only distantly related to Kentriodon.
Xenocephalus is a genus of bony fish from the family Uranoscopidae, the stargazers. They are found in the Indo-Pacific region and are benthic, ambush predators.
Ichthyscopus is a genus of stargazers from the family Uranoscopidae. They are ambush predators from the western Indo-Pacific region.
Kathetostoma is a genus of bony fish from the family Uranoscopidae, the stargazers. They are demersal predators which are found in the western Atlantic, Pacific and Indian Oceans, with most species around Australia and New Zealand.
The scaly stargazer is a stargazer of the family Uranoscopidae. It is a demersal species which has been recorded at depths between 40 and 800 metres, although it is most commonly recorded at 200–400 metres (660–1,310 ft). It has a maximum length of 33 centimetres (13 in). It is found in the South Atlantic, southern Indian Ocean and south western Pacific Ocean; in the South Atlantic it has been recorded from the Rio Grande Rise and the Walvis Ridge to the coasts of Namibia around southern Africa to the Madagascar Ridge, south of the island of Madagascar, in the south western Indian Ocean; in Australia it occurs from Western Australia and northern New South Wales, around New Zealand, and it also occurs on ocean ridge near Norfolk Island. It is the only species in the monotypic genus Pleuroscopus.
Selenoscopus is a monotypic genus of stargazer from the family Uranoscopidae. The only species in the genus is Selenoscopus turbisquamatus, a bathydemersal species found in the western Pacific Ocean from Japan to the northern Tasman Sea at depths of 100–500 metres (330–1,640 ft).
Uranoscopus brunneus, the dark-finned stargazer, is a member of the group Uranoscopidae, the benthic living fishes distributed worldwide in tropical and temperate oceans.
