A fossil mold is formed by the impression left in rock by the remains of an organism. A cast fossil occurs when the mold is filled in by precipitating minerals.
A mold is a hollow rock left by an organism,
A cast is when the rock is filled with sediment.
They both are usually found in creeks, rivers, and streams.
A mold is a negative imprint,
While a cast preserves the external form of the organism.
Both are evidence of once living animal activity.
Molds 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.
A fossil mold is formed by the impression left in rock by the remains of an organism. A cast fossil occurs when the mold is filled in by precipitating minerals.
They are all fossils but casts are raised while molds are indentations
a mold fossil is the impression that are in a rock. a cast fossil is filled by minerals

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.
cast
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.
A cast fossil is used to preserve the hard parts associated with an organism or species. Fossils are most commonly used in regards to dinosaurs.
Paleontologists are looking for fossils in sedimentary rock.
a mold is what you pour materials into to make a cast
Imprint fossils, Mineralized fossils, frozen fossils, fossils in amber, and cast fossils.

A mold and cast fossil is and exact stone replica of an organism but it is formed like this. The first layer of sediment hardens and forms a mold. then a new layer of sediment fills in the mold and hardens. That is the cast.
mold fossils are either located near water or cliffs.
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.
All are indicative of the size and shape and possible habitat of the original organism.
There are a variety of types of fossils. These include cast fossils, mold fossils, petrified wood, as well as fossil fuels.
There are four types of fossils that can be found. These are true fossils, mold fossils, trace fossils and cast fossils.
Both copy the shape of its ancient organisms.a MOLD is a hollow area in sediment in the shape of an organism or part of an organism.a mold forms when the hars part of the organism,such as a shell,is buried in sediment.Later, water carrys dissolved minerals and sediment there,the result is a cast. A CAST is a solid copy of the shapes of organisms.a cats is the opposite of a mold.both mold and cast preserved details of the animals structure
the 5 types of fossils are: 1.petrified fossil 2.carbon films 3.trace fossil 4.perserved remains 5.mold and cast
yes
