Fig. 9. A. Size comparison between Galeorhinus cuvieri and Eogaleus bolcensis specimens. The total length of MSNPV 24625-24626, MCSNV T.311, and MNHN F.Bol.516 refers to estimated values discussed herein. MSNPV 24625-24626 is the largest of the series. B. Examples of total length-age fits performed with growth parameters of Galeorhinus galeus populations from New Zealand (B1, female growth parameters; Francis and Mulligan 1998) and Australian (B2, combined growth parameters; Moulton et al. 1992) by using VBGF (Bertalanffy 1938; see Table 2 for estimated age values). Both curves discriminate fossil individuals in three main ontogenetic classes: G. cuvieri specimens cluster close to each other on the bottom of the logarithmic trend line. Thus, G. cuvieri specimens were young individuals. On the contrary, E. bolcensis specimens arranged more spaced to each other toward the top of the trend line. Accordingly, E. bolcensis specimens were young or adult individuals, where MSNPV 24625-24626 is the largest of the series.
