We have just installed an evolution exhibition, Charley and Kiwi's  
Evolutionary Adventure in which we have a "dino dig"
exhibit (actually casts of Moa bones) and we are using the formula  
Maureen referred to via Sean Duran at Miami Museum of Science who was  
at the Academy of Sciences in Philadelphia.

We use wooden tools used for clay sculpting and brushes. It is  
extremely popular with younger children < 5 to 10 yo and older.

When the bones get very exposed (empirically determined) our exhibits  
shop prepares more substrate and pours in onto the remaining substrate.

I will look for the recipe as sent to me by Sean and pass it on.
