Dinosaur trackways are fossil footprints of dinosaurs, which are found all over the world. These trackways developed as dinosaurs (and other animals) walked in the soft sediment or sand along the shorelines of beaches, rivers, ponds, and lakes. Almost immediately after the animals walked by, the tracks were quickly buried in sediment, eventually becoming fossil footprints (also called ichnotaxia). Because such places were good sources of water and food, including lush plants for the herbivores, and plenty of animals for the carnivores, they became natural pathways for all types of dinosaurs. (In fact, the branch of science concerned with the study of footprints is called ichnology.)

So far, the problem with dinosaur trackways is that it is impossible to tell what dinosaur made the footprints. Scientists can only give general an idea of the animals, such as if the tracks belonged to a biped or quadruped dinosaur, and often a sauropod versus a theropod. But that is usually all they can tell from a footprint.
