CASTING AND MOLDING FOSSILS
CASTING & MOLDING
A cast is essentially a copy of a bone. Sometimes it is called a replica. The advantages of a cast are that it is lighter and stronger than real bone. It retains all of the external details of the original specimens.
|A two part mold can be made from an original fossil. The bone is supported with clay and building blocks.|
|More clay is used to cover about half of the original fossil.|
