the upper jurassic, however, is well represented in africa, mainly thanks to the spectacular tendaguru formation, a lagerstätte in southeastern tanzania. "allosaurus", "ceratosaurus", "elaphrosaurus", "giraffatitan", "dicraeosaurus", "janenschia", "tornieria", "tendaguria", "kentrosaurus", and "dryosaurus" are among the dinosaurs whose remains have been recovered from tendaguru. this fauna seems to show strong similarities to that of the morrison formation in the united states and the lourinha formation in portugal. for example, "allosaurus", "ceratosaurus", and "dryosaurus" have been found in both the tendaguru and the morrison. this has important biogeographical implications. this means the animals could travel between most continents at that time (pangaea).
