The Museum itself is pretty small and dogs are not allowed inside. But they're allowed in the quarry. Just make sure dogs and children stay close to you as the trucks are driving at a high speed. You can take a walk through the limestone quarry or borrow a hammer and chisel to dig for fossils yourself. It's pretty cheap to borrow the utensils but our hammer was broken and the head kept falling of so it wasn't of any use. You don't really need the utensils anyway, just look through the rumble on the sides and you should find at least some corrals. Also don't dress in your best clothes since you will get pretty dirty and watch out for the trucks and other vehicles. They're driving at a pretty high speed for a place where pedestrians might be walking. But don't jump to the side to get out of their way, you might just loose a shoe in the wet muddy limestone.
