Agaleus

Agaleus is an extinct genus of stem Galeomorph shark from the Early Jurassic Epoch. It is a monotypic genus at present consisting solely of the species A. dorsetensis. It is known from the Sinemurian of Lyme Regis, England and the Pliensbachian-aged Hasle Formation of Denmark.[1] Other places which have produced this species include Northern Ireland, France, Belgium, and Sweden. Possible later occurrences of this genus in northwest Europe have been documented but not yet formally attributed to the genus. Some have placed this species to be a basal member of the order Orectolobiformes, but subsequent researchers have found it to be a stem-Galeomorph just outside the crown group of Orectolobiformes.[2] This species is currently only known from isolated teeth.
