"Researchers have used 'network theory' for the first time to visually depict the movement of dinosaurs around the world during the Mesozoic Era -- including a curious exodus from Europe. The research, published today in the Journal of Biogeography, also reaffirms previous studies that have found that dinosaurs continued to migrate to all parts of the world after the 'supercontinent' Pangaea split into land masses that are separated by oceans. Study lead Dr Alex Dunhill from the School of Earth and Environment at the University of Leeds, said: "We presume that temporary land bridges formed due to changes in sea levels, temporarily reconnecting the continents." "Such massive structures -- spanning, for example, from Indo-Madagascar to Australia -- may be hard to imagine. But over the timescales that we are talking about, which is in the order of tens of millions of years, it is perfectly feasible that plate tectonic activity gave rise to the right conditions for such land bridges to form."
