Hi! I am a freshman at Clemson University studying Biological Sciences.

Please read the reliable sourcing policy. I've removed one commercial source (www.petrifiedwoodco.com) from Petrifaction and note a couple of other questionable ones: the www.ncsec.org website and the Creabel website. Please review those with respect to the above policy and find some better sources. Thanks, Vsmith ( talk) 01:52, 4 April 2012 (UTC) reply
