Is the "Substitution pseudomorph" phenomenon anything like [becoming] "petrified"? edit

Is the phenomenon described in the "Substitution pseudomorph" section the same as (or, similar to) the phenomenon that is responsible for creating "petrified" evidence, of certain erstwhile forms? (such as, a petrified clam?)

(I have a petrified clam in my house. It is a rock, but its shape is the shape of a clam.)

Just curious!

PS: If the answer is yes, then would this be a good candidate for being mentioned in that section of the article? Thanks, --Mike Schwartz (talk) 20:13, 23 October 2014 (UTC)Reply
