Fig. 3 in The oldest fossil record of the megamouth shark from the late Eocene of Denmark, and comments on the enigmatic megachasmid origin

Fig. 3. Priabonian (late Eocene) paleogeographic map (after Smith et al. 1994: 29) showing the fossil record of "applegatei-grade" Megachasma (i.e., M. alisonae sp. nov., M. applegatei, or M. cf. M. applegatei) from Eocene, Oligocene, and Miocene–?Pliocene deposits as well as "pelagios-grade" Megachasma (i.e., M. pelagios or M. cf. M. pelagios) from post-Oligocene deposits. Asterisk indicates inferred taxonomic identification (see text).
