Agaleus is an extinct genus of stem-galeomorph shark from the Early Jurassic Epoch. The genus Agaleus is monotypic, consisting solely of the species Agaleus dorsetensis. This species is currently only known from isolated teeth.
Taxonomy[edit]
Some authorities have placed this species as 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.[1]
Distribution[edit]
It is known from the Sinemurian of Lyme Regis, England and the Pliensbachian-aged Hasle Formation of Denmark.[2] Other places which have produced this species include Northern Ireland, France, Belgium, and Sweden. Possible later occurrences of this genus in north-western Europe have been documented but not yet formally attributed to the genus.
