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.[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.[1] 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

[edit]

When the family Archaeolamnidae was first named, it contained Archaeolamna, Cretodus, Dallasiella, and Telodontaspis.[2] 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.
