Sorry, no etymologies found.
The back teeth become small and are relatively shorter than the side teeth, presenting in this respect an approach to the form of the teeth described as the galeocerdo latidens.
This genus is an inhabitant of our present seas, and the species arcticus (Fig. 49) very closely resembles the galeocerdo aduncus, whose teeth are abundant in the miocene marl beds of North-Carolina.
The teeth of this species of fish occur in the miocene associated with those belonging to the genera galeocerdo and lamna.
Thus, Fig. 49, shows a front section of the lower jaw of the galeocerdo arcticus; the outer row standing upright,
In two species of galeocerdo which differ in size, the serratures are constant and preserve a great uniformity; and the common character of the serratures seems to be, that which might be called compound, by which I mean, that each notch is itself notched, and it is possible that many of the species possessed this character more or less, but have lost it by wear in their usage.
