Cardabiodon is an extinct genus of lamniform shark, which existed in Australia, Canada, and Europe during the Cretaceous period. It was first named by Michael Siverson in 1999, and contains the species Cardabiodon ricki. Cardabiodon ricki first occurred in the late Cenomanian of Alberta, Canada, and is hypothesized in published literature to have a antitropical distribution.
