Another way is called permineralization, after soft parts decay hard parts such as the bones are left behind.

One other way is replacement when groundwater seep into the soft parts of the body washing away minerals and replacing it with the waters new minerals.]]> 2017-01-10 21:01:16 UTC https://padlet.com/adlerc6491/lhyhmswt46ev/wish/146391617 adlerc6491 https://padlet.com/adlerc6491/lhyhmswt46ev/wish/146928394
