Coelacanths (/ ˈ s iː l ə k æ n θ / ⓘ SEE-lə-kanth) (order Coelacanthiformes) are an ancient group of lobe-finned fish (Sarcopterygii) in the class Actinistia. [2] [3] As sarcopterygians, they are more closely related to lungfish and tetrapods (which includes amphibians, reptiles, birds and mammals) than to ray-finned fish.
Prehistoric fish are early fish that are known only from fossil records. They are the earliest known vertebrates, and include the first and extinct fish that lived through the Cambrian to the Quaternary. The study of prehistoric fish is called paleoichthyology. A few living forms, such as the coelacanth are also referred to as prehistoric fish ...
Teays River. The Teays River network, which existed before disruption by glaciers during the Pleistocene. Reconstruction is based on the discovery of large buried valleys in West Virginia, Ohio, and Indiana and other evidence. The Teays River / ˈteɪz / [ 1] (pronounced taze) was a major preglacial river that drained much of the present Ohio ...
Leedsichthys is an extinct genus of pachycormid fish that lived in the oceans of the Middle to Late Jurassic. [ 1] It is the largest ray-finned fish, and amongst the largest fish known to have ever existed. [ 2] The first remains of Leedsichthys were identified in the nineteenth century. Especially important were the finds by the British ...
Researchers said they looked at ancient fish teeth from the carp family recovered from Gesher Benot Ya’aqov, a waterlogged area that once sat on the shore of the paleolithic lake Hula in the ...
