Research Sites:
Mahajanga province, northwestern Madagascar

Research Project:
Late Cretaceous vertebrate fossils from the Mahajanga Basin, Madagascar: Implications for the Biogeographic and Plate Tectonic History of Gondwana. Short title: The Mahajanga Basin Project.

Research Focus:
The objective of our project is to discover and collect fossils of terrestrial and freshwater vertebrates from Late Cretaceous rocks in the Mahajanga Basin of northwestern Madagascar and to employ these discoveries in studies of systematics, functional morphology, biostratigraphy, paleoecology, and biogeography. Through the course of eight, large-scale expeditions, beginning in 1993, the Mahajanga Basin Project has more than quintupled the species richness of Late Cretaceous vertebrates from Madagascar and profoundly altered concepts concerning the plate tectonic breakup of the southern supercontinent Gondwana, and how that fragmentation affected the distributions of vertebrate animals. Another mission is to build schools and clinics in remote areas of the island through the Madagascar Ankizy Fund (www.ankizy.org), an organization established in 1998.
