A similarity in both recrystallization and replacement modes of preservation is that delicate tissue and organs are not preserved.
<h3>What are recrystallization and replacement modes of preservation?</h3>
Recrystallization is a mode of preservation of fossils in which the internal structure of the fossils is changed by addition of more minerals to form larger crystal of the same material.
Replacement is a mode of preservation in which new material replaces the original material in the fossil.
