A PLIOCENE GRAY WHALE (ESCHRICHTIUS SP.) FROM THE EASTERN NORTH ATLANTIC ...
The gray whale Eschrichtius robustus, the only living member of the eschrichtiid lineage, currently inhabits only the North Pacific. Interestingly, however, the holotypes of both E. robustus and the late Miocene Archaeschrichtius ruggieroi (the oldest known eschrichtiid species) come from the North...
