Sometimes a fossil is formed when the organic matter is impressed in clay or some similar substance. The organic substance rots away, but the impression it left remains, and if the clay which holds the impression petrifies, it becomes a fossil.
This is called a trace fossil. or a mold.
A cast fossil is formed when minerals fill in an impression left by an organism.
No. At one time yes. It must be very old. Definition of fossil per www.dictionary.com: any remains, impression, or trace of a living thing of a former geologic age, as a skeleton, footprint, etc.
A fossil is evidence of a once living animal. A fossil is created when an animal dies in a mud or other soft dirt or sediment. Over time, the animal will decompose and leave the bones. Over time, these bones will get covered by dirt, rocks water, etc. After a couple thousand years the bones will get compressed into sediment, waiting to be discovered. Something similar to a fossil is and imprint. This is where an impression of a plant or animal is pushed into a soft sediment and hardens.
You'll never get a second chance to make a good first impression.
Yes.
This is called a trace fossil. or a mold.
A fossil created by a print or impression is called an imprint fossil. Imprint fossils are formed when an organism's remains leave an impression in sediment that hardens over time. This process captures the shape or texture of the organism, providing valuable information about ancient life forms.
Lets go find the definition to impression?

Ichnofossil, or an impression fossil. http://en.wikipedia.org/wiki/Trace_fossil
A fossil is a non-living thing. It is the preserved remains or impression of a once-living organism.
A mold fossil is formed when an organism decays and leaves an impression in the surrounding sediment or rock. Over time, the impression fills with minerals, creating a cast of the organism's shape.
That would be a fossil.
