Amazonsaurus - Biogeography

Biogeography

Basal diplodocoids are found in several parts of South America, as well as northern Africa, during the Early Cretaceous, as are titanosaurian sauropods, and the carcharodontosaurid and spinosaurid theropods. By the Late Cretaceous Period, the diplodocoids had gone extinct, while titanosaurs proliferated. The predatory theropod families of the Early Cretaceous were also replaced by abelisaurid theropods throughout the southern continents during the Late Cretaceous (Carvalho et al., 2003; Novas et al., 2005).
