Formation (stratigraphy)
A geological formation, or simply formation, is a body of rock having a consistent set of physical characteristics (lithology) that distinguishes it from adjacent bodies of rock, and which occupies a particular position in the layers of rock exposed in a geographical region (the stratigraphic column). It is the fundamental unit of lithostratigraphy, the study of strata or rock layers. A formation must be large enough that it can be mapped at the surface or traced in the subsurface. Formations are otherwise not defined by the thickness (geology), thickness of their rock strata, which can vary widely. They are usually, but not universally, tabular in form. They may consist of a single lithology (rock type), or of alternating beds of two or more lithologies, or even a heterogeneous mixture of lithologies, so long as this distinguishes them from adjacent bodies of rock. The concept of a geologic formation goes back to the beginnings of modern scientific geology. The term was used by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cretolamna Profile, Artistic Impression
''Cretalamna'' is a genus of extinct otodontid shark that lived from the latest Early Cretaceous to Eocene epoch (about 103 to 46 million years ago). It is considered by many to be the ancestor of the largest sharks to have ever lived, ''Otodus angustidens'', ''Otodus chubutensis'', and ''Otodus megalodon''. Taxonomy Research History ''Cretalamna'' was first described by Swiss naturalist Louis Agassiz using five teeth previously identified as the common smooth-hound and collected by English paleontologist Gideon Mantell from the Southerham Grey Pit near Lewes, East Sussex. In his 1835 publication ''Rapport sur les poissons fossiles découverts en Angleterre'', he reidentified them as a new species of porbeagle shark under the taxon ''Lamna appendiculata''. In 1843, Agassiz published ''Recherches sur les poissons fossiles'', which reexamined Mantell's five teeth. Using them, eight additional teeth collected by Mantell, and twenty more teeth collected by various paleontologists in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Myliobatiformes
Myliobatiformes () is one of the four orders of batoids, cartilaginous fishes related to sharks. They were formerly included in the order Rajiformes, but more recent phylogenetic studies have shown the myliobatiforms to be a monophyletic group, and its more derived members evolved their highly flattened shapes independently of the skates. Classification Nelson's ''Fishes of the World'' arranges the Myliobatiformes as: *Suborder Platyrhinoidei **Family Platyrhinidae (thornbacks) *Suborder Zanobatoidei **Family Zanobatidae (panrays) *Suborder Myliobatoidei ( stingrays) **Superfamily Hexatrygonoidea ***Family Hexatrygonidae (sixgill stingray) **Superfamily Urolophoidea ***Family Plesiobatidae (deepwater stingray) ***Family Urolophidae (round stingrays) **Superfamily Urotrygonoidea ***Family Urotrygonidae (American round stingrays) **Superfamily Dasyatoidea ***Family Dasyatidae (whiptail stingrays) ***Family Potamotrygonidae (river stingrays) ***Family Gymnuridae The bu ...

Asteracanthus
''Asteracanthus'' (from el, ἀστήρ , 'star' and el, ἄκανθα , 'spine') is an extinct genus of hybodontiform, known from the Middle Jurassic (Bathonian) to the Early Cretaceous (Valanginian). Description Astercanthus was among the largest known hybodontiformes, reaching a length of 2-3 metres. The dentition of ''Astercanthus'' is high crowned and multicusped. Fossil records This genus has been reported from the Middle Triassic to the Cretaceous, though the genus as currently circumscribed dates from the Bathonian-Valanginian, predominantly of Europe. Fossils are found in the marine strata of United States, Iran, Switzerland, Madagascar, Morocco and Europe. A complete skeleton was described in 2021 from the Late Jurassic (Tithonian) aged Solnhofen Limestone. Previously considered synonymous, the genus ''Strophodus'' (Middle Triassic-Late Cretaceous) is now considered distinct, with the teeth of ''Asteracanthus'' having more in common with ''Hybodus'' and '' Egerton ...

Mitsukurinidae
Mitsukurinidae is a family of sharks with one living genus, '' Mitsukurina'', and four fossil genera: ''Anomotodon'', '' Protoscapanorhynchus'', ''Scapanorhynchus'', and '' Woellsteinia'', though some taxonomists consider ''Scapanorhynchus'' to be a synonym of ''Mitsukurina''. The only known living species is the goblin shark, ''Mitsukurina owstoni''. This family of sharks is named in honour of Kakichi Mitsukuri who brought the holotype of the only species in this family to David Starr Jordon to be scientifically described. The most distinctive characteristic of the goblin sharks is the long, trowel A trowel is a small hand tool used for digging, applying, smoothing, or moving small amounts of viscous or particulate material. Common varieties include the masonry trowel, garden trowel, and float trowel. A power trowel is a much larger gas ...-shaped, beak-like snout, much longer than those of other sharks. Its long snout is covered with ampullae of Lorenzini that enable i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Robeson County, North Carolina
Robeson County is a county in the southern part of the U.S. state of North Carolina and is its largest county by land area. Its county seat is and largest city is Lumberton. The county was formed in 1787 from part of Bladen County and named in honor of Thomas Robeson, a colonel who had led Patriot forces in the area during the Revolutionary War. As of the 2020 census, the county's population was 116,530. It is a majority-minority county; its residents are approximately 38 percent Native American, 22 percent white, 22 percent black, and 10 percent Hispanic. It is included in the Fayetteville–Lumberton–Laurinburg, NC Combined Statistical Area. The state-recognized Lumbee Tribe of North Carolina is headquartered in Pembroke. The area eventually comprising Robeson was originally inhabited by Native Americans, though little is known about them. By the mid-1700s, a Native community had coalesced around the swamps near Lumber River, which bisects the area. Later in the century ...

Hybodus
''Hybodus'' (from el, ύβος , 'crooked' and el, ὀδούς 'tooth') is an extinct genus of hybodont, a group of shark-like elasmobranchs that lived from the Late Devonian to the end of the Cretaceous. Species closely related to the type species ''Hybodus reticulatus'' lived during the Early Jurassic epoch. Numerous species have been assigned to ''Hybodus'' spanning a large period of time, and it is currently considered a wastebasket taxon that is 'broadly polyphyletic' and requires reexamination. The first fossilized teeth from ''Hybodus'' were found in England around 1845; since then teeth (and dorsal spines) have been recovered from Europe. During the Triassic, Jurassic, and Cretaceous periods, the hybodonts were especially successful and could be found in shallow seas around the world. For reasons that are not fully understood, the hybodonts became extinct near the end of the Late Cretaceous period. Description ''Hybodus'' species grew to about in length. It was not ver ...
