Squalicorax, commonly known as the crow shark, is a genus of extinct lamniform shark known to have lived during the Cretaceous period. The genus had a global distribution in the Late Cretaceous epoch. Multiple species within this genus are considered to be wastebasket taxon due to morphological similarities in the teeth.
Cretodus lived during the Late Cretaceous, ranging from the Cenomanian [2] to the Coniacian [3] (approximately 100 to 89 million years ago). The genus is well-known from strata deposited in the Western Interior Seaway ( North America ), [ 1 ] [ 2 ] [ 3 ] and from the Late Cretaceous of Europe , [ 4 ] Africa , and possibly Asia .
The subtropical regions of the Late Cretaceous that Cretoxyrhina inhabited were dominated by sharks and turtles like the Cretodus and Protosphargis in this fossil. Cretoxyrhina had a cosmopolitan distribution with fossils having been found worldwide. Notable locations include North America, Europe, [67] Israel, [68] and Kazakhstan. [8]
Leptostyrax is an extinct genus of mackerel sharks that lived during the Cretaceous. It contains two valid species, L. macrorhiza and L. stychi, found in North America, Europe, Africa, and Australia. [2] Vertebrae tentatively assigned to L. macrorhiza suggest lengths of 6.3–8.3 m (21–27 ft), making it one of the largest Cretaceous sharks. [6]
Archaeolamna (from Greek arche which turned into archaeo and Lamna, an extinct shark genus) [1] is an extinct genus of mackerel sharks that lived during the Cretaceous.It contains three valid species (one with two subspecies) which have been found in Europe, North America, and Australia.
Sharks portal; Cardabiodontidae is an extinct family of lamniform sharks.Confirmed members of this family include Cardabiodon and Dwardius, both which are genera which existed in Australia, North America, and Europe during the Late Cretaceous period.
During the Cretaceous Period, a genus of sharks roamed the sea with rows of unusual teeth. Mostly large and rounded, these chompers were not meant to slice through their prey, but to grind and ...
The map of North America with the Western Interior Seaway during the Campanian. The Western Interior Seaway (also called the Cretaceous Seaway, the Niobraran Sea, the North American Inland Sea, or the Western Interior Sea) was a large inland sea that split the continent of North America into two landmasses for 34 million years.
