A cast is the fossil type left inside a rock by organism that has decayed.
A mold fossil is formed when an organism dissolves and leaves an empty space in a rock. This empty space can later be filled by other minerals, forming a cast fossil.
No, a thin cavity in a rock showing where a shell has decayed is not considered a fossil. Fossils are the preserved remains or traces of ancient organisms, such as bones, shells, or imprints, that have been naturally preserved in rock or sediment over time. The empty space left behind by a decayed shell would be considered a mold or cast, not a fossil.
A mold fossil is a type of fossil formed when an organism or plant decomposes or is buried in sediment, leaving an impression or hollow shape in the rock. The mold is created when the organic material decays and leaves behind a cavity that is later filled with minerals, preserving the shape of the original organism.
No, a fossil formed when an organism buried in sediment dissolves is called a mold fossil. It is created when the organic material of the organism dissolves, leaving behind an impression or cavity in the sediment that hardens into rock.
There is much space debris. Humans have many decayed satellites and probes floating around.
Mold
a mold fossil is a fossil formed in a rock by a dissolved organism that leaves an empty space, showing its outward space.

The fossil that is formed when an organism is buried in sediment and hardens into rock is called a cast fossil, in which the empty space serves as a mold.
A fossil mold forms when an organism's remains decay and leave behind an empty space in the rock where it was once located. This empty space can then be filled with minerals to create a fossil cast.
A fossil cast is a type of fossil formed when sediments fill in the hollow space left by a decomposed organism. The sediments harden into rock, preserving the shape of the organism in the form of a cast. This can provide scientists with valuable information about the size and shape of the original organism.
No, a fossil formed when an organism buried in sediment dissolves is called a mold fossil. It is created when the organic material of the organism dissolves, leaving behind an impression or cavity in the sediment that hardens into rock.
Mold fossils- an empty space is left when an organism is buried in sedimentary and it decays.Cast fossils- Minerals in rocks fill space left by a decayed organism.(replica)Trace fossils- Markings left by an animal.

The best way to identify fossils is to get a book or website that shows pictures of different types. Most fossils are formed by petrification, where part of the dead organism has slowly changed into rock. However, you might also find a fossil cast, where rock has formed around a dead organism and left a mold; it can either be a hollow space, or more rock may have filled in the shape of the organism. There are even fossil footprints and fossil poo!
