What does a dinosaur's foot print look like?

In fiction, there are very many amounts of dragons of various description. This question is like asking

"What does a shoeprint look like?" They are very varied and it would depend on the type of dragon/shoe in question. For example, a typical dragon such as a wyvern would have large, lizard-like footprints at assumption, but the amphithere has no feet at all. I'm leaving the below comment because I find it funny. :D

A better answer would be: It all depends on which shoes my mother-in-law is wearing. :-)
