The tiger shark is a species of requiem shark and the only extant member of the genus Galeocerdo. It is a large macropredator, capable of attaining a length over 5 m. Populations are found in many tropical and temperate waters, especially around central Pacific islands. Its name derives from the dark stripes down its body, which resemble a tiger's pattern, but fade as the shark matures.
Galeocerdo is a genus of requiem sharks that have lived since the Paleocene epoch. While these sharks were formerly diverse, only G. cuvier survives today.
Palaeoniscum is an extinct genus of ray-finned fish from the Permian period of Europe, North America (Greenland), and possibly other regions. The genus was named Palaeoniscum in 1818 by Henri Marie Ducrotay de Blainville, but was later misspelled as Palaeoniscus by Blainville and other authors. Palaeoniscum belongs to the family Palaeoniscidae.
Physogaleus is a small genus of prehistoric shark that lived from the Eocene to Miocene epochs.
The Choptank Formation is a geologic formation in Virginia and Maryland. It preserves fossils dating from the Miocene epoch of the Neogene period.
The Piney Point Formation is a geologic formation in Virginia. It preserves fossils dating back to the Lutetian Stage of the Eocene Epoch of the Paleogene period.
The Nestucca Formation is a geologic formation in Oregon. It preserves fossils dating back to the Bartonian to Priabonian stages of the Eocene period.
The Temblor Formation is a geologic formation in California. It preserves fossils dating back from the Late Oligocene to the Middle Miocene of the Neogene period. It is notable for the famous Sharktooth Hill deposit.
The Tirabuzon Formation is a geologic formation in Mexico. It preserves fossils dating back to the Neogene period, Pliocene epoch.
The Carrillo Puerto Formation is a geologic formation in Mexico. It preserves fossils dating back to the Late Miocene to Early Pliocene of the Neogene period.
The Leitha Limestone is a geologic formation in Austria, Czech Republic, Hungary and Poland. It preserves fossils dating back to the Middle to Late Miocene period.
The Weissenegg Formation is a geologic formation in Austria. It preserves fossils dating back to the Miocene period.
Galeocerdo alabamensis is an extinct relative of the modern tiger shark from the Eocene found in the Southern US.
The Langental Formation, also spelled as Langetal Formation, is a Late Eocene geologic formation cropping out in the Sperrgebiet, ǁKaras Region of southwestern Namibia. The siltstones and sandstones of the formation were deposited in a shallow marine environment. The Langental Formation was deposited under hot and humid conditions. The formation overlies the Silica Beds unit and is overlain by the Blaubok Conglomerate. The Langental Formation provides many fossil invertebrates and fish.
The Onzole Formation is an Early Pliocene geologic formation in the Borbón Basin of northwestern Ecuador. The formation consists of a shallow marine sandstone member containing many fish fossils, among which megalodon, and a deep water member comprising tuffaceous shales and mudstones containing gastropods, bivalves and scaphopods.
The Calvert Formation is a geologic formation in Maryland, Virginia, and Delaware. It preserves fossils dating back to the early to middle Miocene epoch of the Neogene period. The formation is a destination for amateur fossil hunters as well as professional paleontologists. It is one of the three formations which make up the Calvert Cliffs, all of which are part of the Chesapeake Group.
