The dinosaur set comes with a brick that contains the “fossils” (all plastic) plastic tools (plastic hammer with knife end, brush and a pick) and a plastic base. The brick comes with a very large paper to be able to do this activity indoors to not make a mess. There is also an informative dinosaur guide along with a plastic base.
The dinosaur guide does have theories about how long the dinosaurs lived, such as 100 million years ago. I personally homeschool and don't adhere to that dinosaur theory so just a heads up for those who don't teach that to their children, it is indeed in this set.
There is an entire front and back page, with just Chinese characters too. I was unable to read it as I don't know Chinese but it's odd to find that in the box.
The fossils come in different sizes and pieces, some are larger such as the spine being in tact compared to other little “bones”.
The brick took my son probably a good hour to completely break through. The tools are plastic and the brick is a bit firmer so a lot of pressure is needed to free the fossils from the brick.
Once the fossils are out of the dirt brick, my husband cleaned the dirt off the crevices of the fossils. It took a while as the holes and cracks in the fossils had stuck dirt in them.
The fossils were somewhat difficult to put together. My son needed my help to get them together as they needed more pressure than he was able to do in order to clasp the pieces together. They also come apart while trying to add pieces. It isn't as easy as I thought it'd be. The picture that shows the pieces are vague but with some help, children are able to put them together.
Overall, the price is a good value as it takes a while to complete. It's also a fun activity for homeschooled children where they can learn science but also have fun. My son had a fun time putting it all together. He said it makes him an explorer and like Indiana Jones.
