Article: Teeth of a new neoselachian shark from the British Lower Jurassic

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.
