Antarctic belemnite biogeography and the break-up of Gondwana
In the late Jurassic, the belemnite genera Hibolithes and Belemnopsis were abundant and widespread in Tethys, characterizing a Tethyan Realm that extended south from southern Europe and Asia to Antarctica and the rest of Gondwana. Although a distinct Southern Hemisphere ‘Austral’ belemnite realm cou...

In the late Jurassic, the belemnite genera Hibolithes and Belemnopsis were abundant and widespread in Tethys, characterizing a Tethyan Realm that extended south from southern Europe and Asia to Antarctica and the rest of Gondwana. Although a distinct Southern Hemisphere ‘Austral’ belemnite realm counterbalancing the northern Boreal Realm was absent, it is clear that a significant degree of endemicity existed at the species level, with distinct species groups in Indonesia, Madagascar, Australasia, South America and so on. Trans-Gondwanan faunal links first developed in the late Jurassic shelf seaway between Antarctica, Madagascar and India. Belemnopsis became extinct in southern Europe, and was left as a relict, endemic to this trans-Gondwanan seaway.
