It takes several millions of years for a fossil to be created. First an animal may step in mud whichs dries over time and becomes hard. After it has that mold the conditions have to be right for it to form. If they are then it will form.
No current plants, but some fossil imprints are of long dead plants (usually from about 1/4 billion yeas ago).
Fossil.
A fossil is the preserved remains or traces of a once-living organism, while an imprint is a mark or indentation left behind by an organism on a surface. Fossils can include imprints, but not all imprints are considered fossils. Fossils provide more detailed information about the organism's structure and biology, while imprints are more surface-level.
yes, but they are only usually imprints as sponges decompose after a certain amount of time
Fossils are created by the mineralization of the remains of dead organisms, especially their skeletons. Sometimes there are fossil imprints where remains were pressed into rock, ash, or sediment that later hardened. More rarely, an animal part decomposes and the space is filled to form a cast impression. (see the related link)
the skull fossil
The plural of fossil is fossils.
To identify a fossil rock, look for imprints or remains of ancient plants or animals embedded in the rock. Fossil rocks often have distinct shapes or textures that differ from the surrounding rock. Additionally, you can use tools like a magnifying glass or a field guide to help identify the specific type of fossil present in the rock.
A True form fossil is a fossil of the whole/entire body of the organism.
A hardened and preserved footprint is an example of a fossilized trace fossil. Trace fossils are marks or imprints left behind by ancient organisms, providing insights into their behaviors and interactions with their environment.
the opposite of a fossil is what i just seen. where the imprints are opposite but exprints, it is like the original fossil, or piece of fossilized flesh was somehow reheated bent and refossilized again. so it is per say " inside out " you need to see a picture to understand. it is see through like an aggot. but has the oldest fossil properties.
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.
