Archaelamnidae is an extinct family of sharks from the Cretaceous period. When Underwood & Cumbaa proposed the family in 2010, they included Archaeolamna, Cretodus, Dallasiella,and Telodontaspis.[1] However, Cook et al. 2011 found Archaeolamna the only genus which could be confidently attributed to the family, making it monotypic.[2] Telodontaspis has been considered by subsequent researchers to be a junior synonym to Cretoxyrhina which is within its own family, Cretoxyrhinidae.[3] Likewise, Cretodus has been placed in the proposed family Pseudoscapanorhynchidae by some authors.
