Abstract
According to our hypothesis, Heterostegina ocalana migrated eastward through the previously much narrower Atlantic Ocean around the Eocene/Oligocene boundary. Sporadic populations of H. n. sp., its phylogenetic successor, survived in the western part of the Neotethys until the end of the Rupelian, when they became extinct.| File | Dimensione | Formato | |
