What is the difference between a cast fossil and a mold Fossil?
Scientists use fossils to determine what life was like during prehistoric times.A petrified fossil is an impression of a living thing and can be either a mold or cast.There are several different types of fossils.There are some differences.
A mold fossil is an impression.Substrate is a term for petrified rock.The fossils are hollow.The way they are imprinted makes them offer a backwards look at the creature.teeth, claws, skin and embryos are the most common mold.They can include organisms such as leaves.
mold fossils are very similar to cast fossils.Like mold fossils, they form and are imprinted.Instead of being hollow, minerals, rocks or other materials have filled in the gaps for a more solid fossil.Cast fossils are similar to mold fossils.
A trace fossil is different from mold and cast fossils.
trace is the word that means "trace." Examples of trace fossils include footprints, nest, tooth marks, excrement and burrows.Information about life during prehistoric times can be found in trace fossils.
A true form fossil is a limb or a large part of an organisms that has become petrified over time by means of rocks and minerals.They are not an impression, but an actual part of a living thing.True form fossils include heads, fingers, torsos and limbs.
