A small schooling fish, Knightia made an abundant food source for larger Eocene predators. The Green River Formation has yielded many fossils of larger fish species preying on Knightia; specimens of Diplomystus, Lepisosteus, Amphiplaga, Mioplosus, Phareodus, Amia, and Astephus have all been found with Knightia in either their jaws or stomachs.

Ichthyornis (meaning "fish bird", after its fish-like vertebrae) is an extinct genus of toothy seabird-like ornithuran from the late Cretaceous period of North America.Its fossil remains are known from the chalks of Alberta, Alabama, Kansas (Greenhorn Limestone), New Mexico, Saskatchewan, and Texas, in strata that were laid down in the Western Interior Seaway during the Turonian through ...
A study of fossilised faeces and vomit found in Poland last year revealed how early dinosaurs in the Triassic era, 252 to 201 million years ago, competed for food. By examining the fossils for ...
Coelacanths are considered a poor source of food for humans and likely most other fish-eating animals. Coelacanth flesh has large amounts of oil, urea , wax esters , and other compounds that give the flesh a distinctly unpleasant flavor, make it difficult to digest, and can cause diarrhea .
Pachycormiformes is an extinct order of marine ray-finned fish known from the Early Jurassic to the end of the Cretaceous. It only includes a single family, Pachycormidae . They were characterized by having serrated pectoral fins (though more recent studies demonstrated that fin shape diversity in this group was high [ 2 ] ), reduced pelvic ...
A newfound fossil of a jawless fish is the oldest known vertebrate cranium preserved in 3D. The 455 million-year-old find could illuminate how vertebrate heads evolved.
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.
Fossil remains of a probable Luscinia resembling to the larger members of the genus have been found at Polgárdi in Hungary. They date from the Messinian age, around 12 to 7.3 million years ago (Ma) during the Late Miocene subepoch. A Late Pliocene fossil from Rębielice Królewskie , of Piacenzian age (around 3 Ma), could be an ancestral ...
