Fast delivery and product is as described. We are a homeschooled family and my 9 year old wanted to learn about fossils and rocks this year. I ordered this box of fossils and a box of rocks and minerals. Both are amazing. My son and I are very happy with it. However, there are quite a lot of shark teeth, and I wish there was another dinosaur fossil instead of so many shark teeth. Since sharks lose so many teeth every year, I bet a lot of shark teeth have been found, and I think half the shark teeth we get could be an art project in the future. There are quite a few pieces of coprolite and my son thought it was great. It's a big box full of fossils. Maps with pictures and descriptions are useful and entertaining. I also like that it tells where the fossils were found. Many Thanks.
