Later into the Early Cretaceous epoch, the India-Madagascar landmass separated from the rest of Gondwana.[11] By the Late Cretaceous, Madagascar and India had permanently split ways and continued until later reaching their modern configurations.[11]

By contrast to Madagascar, mainland Africa was relatively stable in position through-out the Mesozoic.[11] Despite the stable position, major changes occurred to its relation to other landmasses as the remains of Pangea continued to break apart.[11] By the beginning of the Late Cretaceous epoch South America had split off from Africa, completing the southern half of the Atlantic Ocean.[11] This event had a profound effect on global climate by altering ocean currents.[11]

During the Cretaceous, Africa was populated by allosauroids and spinosaurids, including the largest known carnivorous dinosaurs.[11] Titanosaurs were significant herbivores in its ancient ecosystems.[11] Cretaceous sites are more common than Jurassic ones, but are often unable to be dated radiometrically making it difficult to know their exact ages.[11] Paleontologist Louis Jacobs, who spent time doing field work in Malawi,[citation needed] says that African beds are "in need of more field work" and will prove to be a "fertile ground ... for discovery."[11]
