Researchers use X-ray video of guineafowl walking through poppy seeds to create a 3-D model of how tracks get made

(Phys.org)—A pair of researchers with Brown University used X-ray video techniques to capture the way a guineafowl makes tracks as part of a project aimed at learning more about preserved dinosaur footprints. In their paper published in Proceedings of the National Academy of Sciences, Peter Falkingham and Stephen Gatesy describe how they created their videos and what they learned by watching them and comparing what they found to real dinosaur tracks.
