eli5: Do you have to carve Fossils out of the stone or will they pop out in the form they are in, when the stone it split open?
In: 8
Hi!
I have a fossil bed near my home with many fossils from the carboniferous period in sedimentary rock.
These plants have been carbonized (turned to coal or a coal like substance) while trapped in these layers of sand and mud that have been compressed to form sedimentary rock.
It is possible to use tools to cleave the rock. Sometimes this works well to display the black image of the plant. Other times this makes a mess (probably because of my lack of skill or training).
Fossils with animal bones are from different time periods and may have different characteristics.
