Archaeolamna 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]
Archaeolamnidae
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.
