Neoselachian sharks' teeth from the lower Jurassic of Lyme Regis, Dorset, are described am assigned to Agaleus dorsetensis gen. et sp. nov. The teeth are large, and have a robust central cusp, one pair of lateral cusplets, and a prominent basal flange. Longitudinal ridges are present on the labial crown shoulder and the root has a strong labial buttress. The vascularization is hemiaulacorhize. Comparison with the teeth of Recent and fossil neoselachians indicates that Agaleus is a benthonic orectolobiform galeomorph.
