Previously, the oldest record of dinosaurs was from Brazil and Argentina and dated back to the mid-late Carnian stage, about 233.23 to 231.4 million years ago. Nyasasaurus comes from a deposit conventionally considered Anisian in age, meaning that it would predate other early dinosaurs by about 12 million years. [ 1 ]
This is a list of non-avian dinosaurs whose remains have been recovered in Africa.Africa has a rich fossil record. It is rich in Triassic and Early Jurassic dinosaurs. . African dinosaurs from these time periods include Megapnosaurus, Dracovenator, Melanorosaurus, Massospondylus, Euskelosaurus, Heterodontosaurus, Abrictosaurus, and Lesoth
Found in association with a skeleton of the sauropod dinosaur Spinophorosaurus, the tooth likely dates to the Bathonian stage of the Middle Jurassic, 14 million years prior to Ostafrikasaurus. If this identification is correct, MUPE HB-87 represents the oldest known evidence of spinosaurids in the fossil record.
The oldest fossils are found on this surface, dated at 1.89 mya, while stone tools have been dated at 1.7 mya through the first use of K-Ar dating by Garniss Curtis. In addition, fission track dating and paleomagnetism were used to date the deposits, while amino acid dating and Carbon-14 dating were used to date the bones. Hominid fossils and ...
The Egyptian dinosaur fossil depicted there differs significantly from more recent Carcharodontosaurus found in Morocco ... The findings suggest dinosaurs of North Africa were much more diverse ...
Nqwebasaurus is a basal coelurosaur and potentially the basal-most member of the coelurosaurian clade Ornithomimosauria from the Early Cretaceous of South Africa. [1] The name Nqwebasaurus is derived from the Xhosa word Nqweba which is the local name for the Kirkwood district, and thwazi is ancient Xhosa for "fast runner". [2]
The Stormberg Group contains South Africa's earliest dinosaur fossils. It also contains the fossil remains of the shrew-sized Megazostrodon, the oldest mammal in Africa. [5] A remarkable array of insect and plant fossils are found in some of the strata. [11]
More than 260 dinosaur footprints discovered in Brazil and Cameroon provide further evidence that South America and Africa were once connected as part of a giant continent millions of years ago.
