Most dinosaur footprints are somewhat less than perfect.
They may show clear outlines of the toes, but little of the finer details. Where to look for prints in the rocks. The preservation of footprints depends greatly on the nature of the substrate being walked upon. For example, you would be unlikely to find a track preserved in what was a very dry, sun baked sediment. Equally deep water sediments are unlikely to be disturbed by terrestrial vertebrates.
