		Description
Original diagnosis after Woodward (1895) p. 4-5 [2600]: The teeth are shown of the natural size in Plate I. figs. 5-7, the first or type specimen being exposed from the inner asjiect, the others exhibiting the outer face. The crown is very low and its apex turned sharply backwards ; the anterior coronal margin is gently arched and marked towards the base with a few feeble denticulations ; the apex above the posterior notch is small and narrow; the margin below the posterior notch is much elongated and exhibits from seven to nine conspicuous denticles, decreasing in size backwards. The root is narrow, and the nutritive foramen on the inner side is in a deep vertical groove (fig. 5).
These Cretaceous teeth are much smaller than those of the typical Galeocerdo of Tertiary and Recent date, and differ from the majority in their remarkably low crown and the relatively small size of the apex of the tooth. They are most nearly paralleled by the teeth named Galeocerdo lutidens from the Eocene of Bracklesham ; but even the latter exhibit a much more prominent apex and relatively smaller posterior denticles. They are thus distinctly new and may receive the provisional name of Galeocerdo Jaekeli, in compliment to the author of the most important contribution hitherto made to our knowledge of the extinct Carchariidae (O. Jaekel, Die eocänen Selachier von Monte Bolca (1894), pp. 156-175).
