Hybodus is thought to have been an active predator which was capable of consuming swiftly moving prey, [18] probably predominantly cephalopods and, to a lesser extent, fish. [19] Based on fossilized stomach contents, it has been proposed that Hybodus was a more active hunter than its close relatives like Asteracanthus, which likely fed on ...
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.
The earliest fossils are of teeth and come from the Devonian period. The only living holocephalans are the chimaeras (Chimaeriformes), though during the late Paleozoic ( Carboniferous and Permian ) Holocephali was much more diverse, including an array of forms including those considerably different from modern Chimaeriformes, including shark ...
3D restoration. Haikouichthys is about 2.5 cm (1 in) long and is narrower than Myllokunmingia, another putative chordate that comes from the same beds. [2] The holotype of Haikouichthys ercaicunensis was found in the Yuanshan member of the Qiongzhusi Formation in the 'Eoredlichia' Zone near Ercai Village in the Haikou Subdistrict (not to be confused with the city of Haikou in Hainan) of Xishan ...
Unlike other flattened placoderms, they were freshwater fish. Their armour was made of whole plates, rather than the numerous tubercles and scales of Petalichthyida. The eyes were on the sides of the head, unlike visual bottom-dwelling predators, such as stargazers or flatfish, which have eyes on the top of their head. The orbits for the eyes ...
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.
Leedsichthys, a giant Jurassic pachycormid. This list of prehistoric bony fish is an attempt to create a comprehensive listing of all genera from the fossil record that have ever been considered to be bony fish (class Osteichthyes), excluding purely vernacular terms.
A distinctive dinosaur known for its long neck, big body, long tail, and a small head, the dinosaur, which probably stood about 10 feet tall and measured 16 feet long, is believed to have ...
