Goldilocks explains lack of dino tracks

摘要

The Goldilocks Effect - where all conditions have to be 'just right' - might explain why dinosaur tracks have been preserved in some areas and not in others. Researchers from the University of Manchester used finite element analysis - a computer modelling technique common in engineering - to simulate dinosaurs making tracks in different types of mud. They found that conditions needed to be just right for a print to be created.
