Haimirichiais an extinct genus ofmackerel sharkfrom the lateCenomanian epochof theCretaceousperiod.[1]It currently contains a single species:H. amonensis.Teeth now assigned to this genus were originally attributed to theOdontaspis.Exquisitely preserved remains from theAkrabou FormationLagerstättein Agoult,Moroccoallowed the species to be moved into a new genus and family.[2]Microscopic study revealed specialized dermaldenticleslikely used inelectroreception.[3]Its tooth and head design suggest a lifestyle similar to the extantTriaenodon obesus,a novel one for Lamniformes.Roulletiahas a similar tooth design and may be part of the same family.[2]
