Cast Fossils: an imprint that is filled in, then fossilized Permineralization: process in which an organism dies and sediment enters the body, filling in the pores of a leaf, or a bone or a shell Whole Body Preservation: occurs when the total organism is fossilized; may occur through freezing or falling in tree amber
Write on the bottom of each fossil their name and if it is a cast or mold. Have students form two lists to describe what they see in the two 'fossils', hair, shape, texture, size, color, etc. Have students write on paper which fossil gives them the most information, mold or cast (3-D) and why.
