To find the movement of dinosaurs around the world during Mesozoic Era the researchers have used the ‘Network Theory’ this also includes a curious exodus from Europe.
According to the study published in Journal of Biography that has found that dinosaurs continued to migrates around the world to each and every place after the ‘Supercontinent’ Pangaea split into land masses that separated by an ocean.
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.”
The researchers used the Paleobiology database that contains every document and accessible dinosaur fossil from the world. Fossil records the same dinosaur families from different continents with across mapped for different periods of time.
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.”
Dr. Dunhill said: “This is a curious result that has no concrete explanation. It might be a real migratory pattern or it may be an artefact of the incomplete and sporadic nature of the dinosaur fossil record.”
Dr. James Sciberras, the study co-author from the Department of Biology and Biochemistry at the University of Bath, said, “Network theory has been studied in physics for a number of years, however, it is finally permeating into other disciplines. This idea that most things can, and should, be considered in the context of the whole system will lead to some exciting new findings in a wide range of fields.”
