What is the most common type of fossilization in which the organic portion of an organism is infiltrated or replaced with minerals?

What is the eroded surface that lies between two groups of strata?

What occurs when groundwater carrying dissolved minerals, such as apatite, calcite, and pyrite, infiltrates the pore spaces and cavities of bones, shell or wood? The minerals precipitate out of the water and are deposited in the hard remains.

What is a fracture in the Earth's crust along which rocks move?

What kind of fossil is useful for dating and correlating the strata in which it is found?

What is the term for making a hole by digging. To dig out/extract material from the ground?

The study of fossils is known as what?

What is a layer, or series of layers of rock in the ground?

What is a fossil of a track, trail, burrow, or some other trace of an organism?

What is hardened tree sap, one of the most common resins?

This is a type of fossilization where the organic material becomes dehydrated.

What occurs when groundwater containing dissolved minerals removes the original organic material and replace it with minerals such as silica, calcite and pyrite. This gradual substitution results in a near-perfect replica of the original organism.
