Fossils formed when silica is added are called silicified fossils. Silica replaces the original organic material of the organism, resulting in a preserved fossil with a glassy appearance. This process can produce detailed and well-preserved fossils.
petrified
skeletonized

no. AA has a relatively low silica content level.
the conditions under which the organism died and how it was buried
