Sea shells are hard carbon components, thus they are ideal objects for fossilization. Many of our current disscovered fossils are in fact sea shells from the various epochs. They can tells us of the evolutionary changes in species such as mollusks.
The imprint of a leaf in a stone is considered a fossil because it's a proof that a leaf or another part of a plant has been preserved on the form of an image of the leaf, since it has the actual shape of a leaf, the ribbings and other features.
It depends. Not all rocks have fossils. Some do. Igneous and metamorphic rocks cannot contain fossils. Sedimentary rocks can, but not all do.
Yes they are.

A fossil

The strata or rock layers of the grand canyon walls are undisturbed. As such, a layer of rock containing a fossil, that is below an overlying rock layer will be older.
A fossil created by a print or impression is called an imprint. The word "imprint" means to produce a mark a on a surface with the use of pressure.
Trace fossil
Which principle is a geologist applying when deciding that a fossil in a mud layer is older than a fossil in a sandstone layer above it.
A fossil is the imprint hardened into rock. An imprint is the print that the organism makes in mud or the ground.

A fossil is a remnant or trace of an organism of a past geologic age, such as a skeleton or leaf imprint, embedded and preserved in the earth's crust. == ==

Imprint
A fossil I pressume. . . Well the leaf is buried in some gloopy mud, and the mud drys around it making a cast / impression. The leaf rots a away after this because it is so fragile. The mud is lithified and bingo an impression. Am I barking up the right tree. . .

fossil
An imprint fossil is formed when an animal or plant makes a print in the soil. Such as a footprint.
