Studying the origins and movement of animals often requires the presence of live animals. However, this is not always possible (in the case of extinct species), safe or practical. In such cases, scientists now have another option: developing three-dimensional models of the animal.
This is what the researchers at the University of Missouri (MU) and the University of Southern Indiana have done. Using cutting-edge imaging and computational tools, they have developed three-dimensional models of the skull of the American alligator.
