What type of fossil is created when minerals fill a mold of an organism?

• Mold

• Cast

• Trace Fossils

• Mold

• Cast

• Carbon Film

• Petrified Fossils

What type of fossil is a footprint an example of?

• Mold

• Cast

• Trace Fossils

• Preserved Remains

• Lava and ash

• Minerals, sediment, and water

• Air and organic matter

• Ice and snow

What happens over time to the materials filling a mold fossil that leads to the formation of a cast fossil?

• The materials freeze

• The materials dissolve

• The water evaporates, cementing the sediments together

• The materials expand

According to the helpful hint, if a mold fossil is the cake pan, what would a cast fossil be?

• The oven

• The cake you bake in it

• The frosting

• The chef
