∙ 12y agoMolds are imprints from a shell or the skin of an animal. A cast is formed when a mold is filled with sediment and hardens into rock.
A:If the original organism dissolves or decays, leaving a hollow in the rock, that is a mold.If the mold fills up with sediment which gradually hardens into the shape of the original organism, then that is a cast.
Casts are copies of fossilized plants or animals. Molds are hollow impressions of the fossil.

What are the types of fossils?
molds and casts, trace fossils, petrified wood, and carbon filmThe four types of fossils are mold fossils, cast fossils, true-form fossils, and trace fossils. Mold fossils are impressions from when the plant or animal first decomposed. Cast fossils are plant or animal remains. True-form fossils are remaining body parts from an animal. Trace fossils are marks that have been left by animal, such as footprints.

What is the difference between a cast and a mold?
Casting requires that you apply a substance to a solid object in order to duplicate a shape. =) hi! Molding requires that you manipulate a substance so that you are literally creating a shape Molds are formed as empty spaces left in a rock when the soft parts of the organism decay and the hard parts are dissolved by chemicals. The mold takes the same shape as the organism. Cast, also known as filled-in molds, are formed when the mold is filled in another material forming a cast that has the same shape as the original organism.
