Archaeolamna (from Greek arche which turned into archaeo and Lamna , an extinct shark genus) [2] 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. [7] [8] While it is mostly known from isolated teeth, an associated set of teeth, jaws, cranial fragments, and vertebrae of A. kopingensis is known from the Pierre Shale of Kansas. [7] Teeth of A. k. judithensis were found with a plesiosaur skeleton with bite marks from the Judith River Formation of Montana. [2] It was a medium-sized shark with an estimated total body length of 3–4 metres (9.8–13.1 ft). [9]

Archaeolamna likely had an antitropical distribution, being found in the temperate waters of both hemispheres but absent from the tropical waters around the equator, much like the modern porbeagle shark. A similar distribution has been found for the related Cardabiodon . [7]

Taxonomy

When the family Archaeolamnidae was first named, it contained Archaeolamna, Cretodus , Dallasiella , and Telodontaspis. [1] However, Cretodus was reassigned to Pseudoscapanorhynchidae, [10] Dallasiella was reassigned to Lamniformes incertae sedis , [11] and Telodontaspis was synonymized with Cretoxyrhina . [12] This leaves Archaeolamna as the sole member of the family.

The Lamniformes are an order of sharks commonly known as mackerel sharks. It includes some of the most familiar species of sharks, such as the great white as well as less familiar ones, such as the goblin shark and megamouth shark.

<i>Cretoxyrhina</i> Extinct genus of shark

Cretoxyrhina is an extinct genus of large mackerel shark that lived about 107 to 73 million years ago during the late Albian to late Campanian of the Late Cretaceous. The type species, C. mantelli, is more commonly referred to as the Ginsu shark, first popularized in reference to the Ginsu knife, as its theoretical feeding mechanism is often compared with the "slicing and dicing" when one uses the knife. Cretoxyrhina is traditionally classified as the likely sole member of the family Cretoxyrhinidae but other taxonomic placements have been proposed, such as within the Alopiidae and Lamnidae.

<i>Enchodus</i> Genus of fishes (fossil)

Enchodus is an extinct genus of aulopiform ray-finned fish related to lancetfish and lizardfish. Species of Enchodus flourished during the Late Cretaceous, and there is some evidence that they may have survived to the Paleocene or Eocene; however, this may just represent reworked Cretaceous material.

The Bearpaw Formation, also called the Bearpaw Shale, is a geologic formation of Late Cretaceous (Campanian) age. It outcrops in the U.S. state of Montana, as well as the Canadian provinces of Alberta and Saskatchewan, and was named for the Bear Paw Mountains in Montana. It includes a wide range of marine fossils, as well as the remains of a few dinosaurs. It is known for its fossil ammonites, some of which are mined in Alberta to produce the organic gemstone ammolite.

<i>Ptychodus</i> Extinct genus of sharks

Ptychodus is a genus of extinct large durophagous (shell-crushing) lamniform sharks from the Cretaceous period, spanning from the Albian to the Campanian. Fossils of Ptychodus teeth are found in many Late Cretaceous marine sediments worldwide.

<i>Cardabiodon</i> Extinct genus of sharks

Cardabiodon is an extinct genus of large mackerel shark that lived about 95 to 91 million years ago (Ma) during the Cenomanian to Turonian of the Late Cretaceous. It is a member of the Cardabiodontidae, a family unique among mackerel sharks due to differing dental structures, and contains the two species C. ricki and C. venator. Cardabiodon fossils have been found in Australia, North America, England, and Kazakhstan. It was likely an antitropical shark that inhabited temperate neritic and offshore oceans between 40° and 60° paleolatitude, similar to the modern porbeagle shark.

<i>Cretalamna</i> Extinct genus of sharks

Cretalamna is a genus of extinct otodontid shark that lived from the latest Early Cretaceous to Eocene epoch. It is considered by many to be the ancestor of the largest sharks to have ever lived, such as Otodus angustidens, Otodus chubutensis, and Otodus megalodon.

The list only includes taxa at the level of genus or species.

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. It has been suggested that Parotodus could also belong to this family, but the authors that originally made this proposal expressed a weakening of rationale for it.

<i>Cretodus</i> Extinct genus of sharks

Cretodus is an extinct genus of large mackerel sharks belonging to the proposed family Pseudoscapanorhynchidae. Cretodus lived during the Late Cretaceous, ranging from the Cenomanian to the Coniacian. The genus is well-known from strata deposited in the Western Interior Seaway, and from the Late Cretaceous of Europe, Africa, and possibly Asia. Cretodus is primarily represented in the fossil record by isolated teeth and vertebral centra, though a couple of associated dentitions and vertebral columns have been found.

<i>Lilamna</i> Extinct genus of sharks

Lilamna is an extinct genus of mackerel sharks from the Wulagen Formation of the Tarim Basin, China. It was originally named Archaeolamna apophysata, but that generic name was preoccupied by Archaeolamna kopingensis. Lilamna was named as a replacement in accordance with the rules of the International Code of Zoological Nomenclature. Although formerly assigned to the family Lamnidae, it is now considered to be a potential member of the family Pseudoscapanorhynchidae. Since this family is otherwise restricted to the Cretaceous, it is possible that the holotype tooth was reworked into the late Eocene sediments it was found in.
