The study of prehistoric fish is called paleoichthyology. A few living forms, such as the coelacanth are also referred to as prehistoric fish, or even living fossils, due to their current rarity and similarity to extinct forms. Fish which have become recently extinct are not usually referred to as prehistoric fish.
Reconstruction of West Indian Ocean coelacanth Preserved Latimeria menadoensis, Tokyo Sea Life Park, Japan. Latimeria chalumnae and L. menadoensis are the only two known living coelacanth species. [8] [27] Coelacanths are large, plump, lobe-finned fish that can grow to more than 2 m (6.6 ft) and weigh around 90 kg (200 lb). [28]
After the appearance of jawed fish (placoderms, acanthodians, sharks, etc.) about 420 million years ago, most ostracoderm species underwent a decline, and the last ostracoderms became extinct at the end of the Devonian period. More recent research indicates that fish with jaws had far less to do with the extinction of the ostracoderms than ...
NEW MEXICO (KRQE) – Researchers have discovered a prehistoric ‘demon-toothed’ fish in Socorro County, New Mexico. The fish, which lived over 300 million years ago, was discovered by New ...
One of the coolest, most prehistoric-looking fish lives in Florida’s offshore waters of the Gulf of Mexico. It happens to be one of the best to eat but also one of the most elusive.
The jawed fish that are still extant in modern days also appeared during the late Silurian: the Chondrichthyes (or cartilaginous fish) and the Osteichthyes (or bony fish). The bony fish evolved into two separate groups: the Actinopterygii (or ray-finned fish) and Sarcopterygii (which includes the lobe-finned fish).
Boaters have been injured, killed by Gulf sturgeon that jump out of the water. They can grow longer than 6 feet & have fleshy "whiskers" on its snout
Arandaspis prionotolepis. This list of prehistoric jawless fish is an attempt to create a comprehensive listing of all genera from the fossil record that have ever been considered to be jawless fish, excluding purely vernacular terms.
