Shells( made of calcite[ca63] recrystallize into calcate. Due to pressure of fluids, the minerals "regrow". Fine Details are erased
|
|
|
Replacement
|
Confused with Recrystallization. Replaces one mineral with a new mineral. Replacing the whole mineral mean the fine details remain.
|
|
|
Permineralization
|
Miner-rich ground water seeps into the pre-space of a fossil filling the material inside. Wood and Bone are commonly preserved this way.
|
|
|

|
Remains are preserved as film of carbon. Look black, and are darker than the rock itself. Common on flatter surface and fine details.
