Dinosaurs and other vertebrates from the Cretaceous of Tanzania
I just came across this interesting paper:
Patrick M. OâConnor, Michael D. Gottfried, Nancy J. Stevens, Eric M. Roberts,
Sifa Ngasala, Saidi Kapilima and Remigius Chami: A new vertebrate fauna from
the Cretaceous Red Sandstone Group, Rukwa Rift Basin, Southwestern Tanzania.
Journal of African Earth Sciences 44: 277-288.
The Rukwa Rift Basin Project was initiated to conduct exploratory field
paleontology in poorly sampled terrestrial strata in southern and western
Tanzania. Here we report the discovery of a series of new fossiliferous
localities from Red Sandstone Group deposits in the Rukwa Rift Basin. These
localities contain a diverse Cretaceous terrestrial/freshwater vertebrate fauna
that consists of members of several major clades, including fishes, turtles,
crocodyliforms, dinosaurs and mammals. Expeditions conducted in the austral
summers of 2002â05 have identified numerous fossil-bearing localities, with
specimens ranging from isolated elements to semi-articulated sauropod and
theropod dinosaurs. Notable among the finds are the most complete mammal
specimen recovered from the Cretaceous of continental Africa, megaloolithid
dinosaur eggshell, and both theropod and sauropod dinosaurs. Given the scarcity
of Cretaceous terrestrial faunas from sub-equatorial Africa, this portion of
Africa Rift System holds great promise for providing new paleontological data
that will contribute to testing and refining a number of biogeographic
hypotheses that have been advanced to explain Gondwanan vertebrate
distributions in the latter half of the Mesozoic.
