a preservation type in which mineral matter has infilled intercellular and intracellular spaces, but has not replaced the cell walls; compare to petrifaction and silification

Permineralization is the process in which minerals are deposited into a bony fossil.

a fossilization process that changes organic matter to rock but preserves all original structures such as cell spaces, growth lines, stress fractures, and tree rings; sometimes called petrification.

Fossilization process that occurs when minerals, carried by ground water, enter and harden in the pores of an organism's structures.

slow replacement of most or all of the organic material in a fossil with mineral crystals (usually silicate).

a process of fossil petrification in which minerals replace bones, shells, or woody tissue without changing the original shape of the fossil. [AHDOS
