fossls

1.) Is a mold fossil because it made an impression and then it was covered so the fossil became hollow.


2.) I think it's Replaced Remains because it looks like the remanis have slowly been replaced molecule by molecule.

Well I think 4 is first because 5 is the second 2 is third 6 is forth then 1 and 3. I think this because the patterns on the picture kind of tell me that and the 2 and 3 I put them were they are because it really looks like looks like it stops mid way and 3 looks like it goes all the way to the top.
