Fig. 5 in Biometric analysis of the teeth of fossil and Recent hexanchid sharks and its taxonomic implications

Fig. 5. Acrocone shape of lower teeth in Recent hexanchid species. Small pictures illustrate the changes in acrocone size according to the L2/L3 values. Interrupted lines are regression curves from data for the two living Hexanchus species. For H. griseus, different symbols have been used to indicate the sex of the sharks (m, male; f, female; ind, indeterminate).
