Complete fossilized skeletons are rare. In fact...it can be a challenge to even find a complete fossilized bone. Many of the skeletons you see in museums include some real fossils (or casts) with sculpted bones & filler to either complete the individual bone or to complete the skeleton. Sometimes the the filler is left white to clearly differentiate the fossil from the filler. Other times, the filler is painted to blend in with the fossil for a more realistic appearance. In this activity I work with the kiddos to finish off one of the partial fossils they found.
