Haimirichia is an extinct genus of mackerel shark from the late Cenomanian epoch of the Cretaceous period.[1] It currently contains a single species: H. amonensis. Teeth now assigned to this genus were originally attributed to the genus Odontaspis. Exquisitely preserved remains from the Akrabou Formation Lagerstätte in Agoult, Morocco allowed the species to be moved into a new genus and family.[2] Microscopic study revealed specialized dermal denticles likely used in electroreception.[3] Its tooth and head design suggest a lifestyle similar to the extant Whitetip reef shark, a novel one for Lamniformes. Roulletia has a similar tooth design and may be part of the same family, Haimirichiidae.[2]
