Creatures in a box

Story:

A mad scientist has challenged you to get all new fossils for your next project with creatures you created. But these body parts are petrified, spread around in various places and split in multiple pieces. So your task is to find the fossil parts at one place and contrive your own tactic to collect them. Then create a creature and send it to these places. After you have collected all parts, you are now allowed to recombine and to unpetrify the fossil and use it to get the rest of the fossils.
Will you be smart enough to reach and hand in all fossils? Find out in Creatures in a box.
