Cosmopolitodus
''Cosmopolitodus'' is an extinct genus of mackerel shark that lived between thirty to one million years ago during the late Oligocene to the Early Pleistocene epochs. Its type species is ''Cosmopolitodus hastalis'', the broad-tooth mako (other common names include the extinct giant mako and broad-tooth white shark). In 2021, ''Isurus planus'' was reassigned to the genus, and thus became the second species '' C. planus''. Its teeth can reach lengths up to 3.5 in (7.5 cm) and are found worldwide. It is believed to be an ancestor to the great white shark, an argument supported by the transitional species '' Carcharodon hubbelli'', but as of 2021, no phylogenetic analyses have been done for proof. Taxonomy Etymology ''Cosmopolitodus'' is derived from the Ancient Greek κοσμοπολίτης "''kosmopolítēs''" meaning "citizen of the world" and ὀδών "''odṓn''" meaning "tooth". The specific name ''hastalis'' may be derived from the Latin word ''hasta'' meaning "spear" ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Isurus Planus
''Cosmopolitodus planus'', also known as the hooked-tooth mako shark or hooked mako shark, is an extinct lamnid that lived during the Miocene epoch from 23 to 5 million years ago. ''C. planus'' can be found only in marine deposits on the Pacific Rim, especially the west coast of the United States.Yabumoto, Y. and Uyeno, T.

Carcharomodus Escheri
''Carcharomodus escheri'', commonly nicknamed the serrated mako shark or Escher's mako shark, is an extinct lamnid that lived during the Miocene. It has been formerly thought to have been the transitional between the broad-toothed "mako" ''Cosmopolitodus hastalis'' and the modern great white, but is now considered to be an evolutionary dead-end with the discovery of ''Carcharodon hubbelli''. Fossil examples have been found along northern Atlantic coastlines and in parts of Western and Central Europe. Etymology ''Carcharomodus'' is derived from the Ancient Greek κάρχαρος "kárkharos" meaning "jagged", όμοιος "omoios" meaning "similar", and δόντι "donti" meaning "tooth". The name was combined with the genus ''Carcharodon'' in reference to the similarity of ''C. escheris dentition with that of the modern great white shark. The species name ''escheri'' is named in honor of Escher. Thus, the species name literally means "Escher's similar to ''Carcharodon'' tooth". ...

Lamnidae - Cosmopolitodus Hastalis
The Lamnidae are the family of mackerel sharks known as white sharks. They are large, fast-swimming predatory fish found in oceans worldwide, though prefer environments with colder water. The name of the family is formed from the Greek word ''lamna'', which means "fish of prey", and was derived from the Greek legendary creature, the Lamia.: ''A source-book of biological names and terms'', 1944, Edmund Carroll Jaeger These sharks have pointed snouts, spindle-shaped bodies, and large gill openings. The first dorsal fin is large, high, stiff and angular or somewhat rounded. The second dorsal and anal fins are minute. The caudal peduncle has a couple of less distinct keels. The teeth are gigantic. The fifth gill opening is in front of the pectoral fin and spiracles are sometimes absent. They are powerful, heavily built sharks, sometimes weighing nearly twice as much as other sharks of comparable length from other families. Many sharks in the family are among the fastest-swimming f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Great White Shark The great white shark (''Carcharodon carcharias''), also known as the white shark, white pointer, or simply great white, is a species of large Lamniformes, mackerel shark which can be found in the coastal surface waters of all the major oceans. It is notable for its size, with larger female individuals growing to in length and in weight at maturity. However, most are sma |
