ABSTRACT
A rich, newly discovered assemblage of exquisitely preserved vertebrate fossils
from the Late Cretaceous of Madagascar provides an unparalleled opportunity to
investigate the paleobiogeography of Gondwanan landmasses. Most current plate
tectonic models depict widespread fragmentation of Gondwana prior to the Late
Cretaceous. The discovery of mammals, dinosaurs, and crocodiles in the latest
Cretaceous (Maastrichtian) of Madagascar that are closely related to forms in
India and South America reveals a cosmopolitanism at or near the close of the
Cretaceous that is paradoxical in the context of these models.
