Gondwana dinosaursPosted: June 16, 2008
A species of carnosaur, Megaraptor, whose fossils had previously only been found in South America may now have been identified in Australia. A bone of contention (see what I did there?), the previously mysterious Australian fossil, a dinosaur forearm, has been identified by paleontologists from the University of Chicago, as belonging to Megaraptor namunhuaiquii.
The implications for the world map in the cretaceous period (145-65 million years ago) would be significant – this find demonstrates that these animals were able to migrate across large areas of the planet’s surface unimpeded from Australia to current-day Argentina.
However, the conclusion is being criticised by some scientists in Australia for placing too much emphasis on a single bone. Have a read of the links; what do you believe?
