What is the difference and similarities between modern dog tracks in mud with mudcracks on a tidal flat to triassic rock with the track of a coelophysis dinosaur Southeast pennsylvania?

This is a question from a laboratory manual for Physical Geology. It is a college level lab book. You have wasted your time to ask the internet (typically genius level intellect) a question that is easily answered with a bit of research and logic. Which are you lacking? The effort to answer the question, or the ability to think your way through it?
ANSWER: You don't deserve to be in college. You are an insult to higher level education. Stop wasting your money and learn a trade.
