Large Fish Fossil Excavation Kit. Each science kit includes 1 of each: earthen plaster block, digging tool, dusting brush, display stand, mallet, sample fossil chip, information guide. The pictures below is an example of one kit - the actual fossils inside each one can be different. Intended for ages 8+. Not for children under 3.

Note, this kit is intended for kids to do hands-on excavation experiment. The digging process has to be done with patience. The whole process may take a few hours or days to complete. That is the essence of the digging fun.  If you would like to quicken the digging process you may spray some water on it. This will soften the plaster. However this may undermine the "digging fun" intended.
