Got this as a gift and the boys went crazy! They all immediately wanted to dig it apart. We started it inside on a towel then moved it outside, it’s a chalking substance when broken apart and pretty easy to cleanup, inside and outside. They wished it was real dinosaur bones but loved digging things out! Definitely recommend. The boys are 2, 5 and 7 years old and all enjoyed it!All of the carnivore cards said herbivore and herbivore cards said carnivore. The symbol on the cards is correct just not the words.The class loved it! The only reason it’s not a 5 star is on their cards the Dino’s come with they say okay eater and meat eater, but they are listed up haha T. rex says plant eater! HahaMy 3 yo absolutely loves this however its super messy! The chalk stained my carpet. But it does take a long time to fully break down. We've worked on this many of day a together!I got this for a birthday gift for one of my sons friends and then my son wanted one as well. Took him a while to dig them all out and then played with them. Hours of funMy son loved it. And it also comes with a dinosaur balloon. And each egg comes with its own stick to break it. Good price. Overall happy with my purchase!Santa gave these to my two kids for Christmas and really pissed me off. The kids loved them. It was too cold to be outside, so I set them up on hard surfaces. Afterwards, the room looked like it had been under construction; everything was coated in a fine tan dust.My kids were occupied for an hour while I was subsequently occupied for 3 hours: sweeping, mopping, shaking out rugs, wiping down all surfaces.Never again, Santa. Never again.I got this for my son's birthday and when I opened the package, nothing was inside of it except the egg (no cards or excavation kit). It was disappointing.. unfortunately I couldn't return it as I had to use it as part of cake table decoration.
