Beelzebufo Posted August 2 Share Posted August 2 They're building a new highway and I found this where they had just dug up. Could this be a fossil or just an interesting stone created by nature. Hopefully you don't mind helping. Link to post Share on other sites

Alex S. Posted August 2 Share Posted August 2 It looks like a pudding stone to me. 1 Link to post Share on other sites
LabRatKing Posted August 2 Share Posted August 2 Just a rock. I see no indications of a fossil in the photos. Link to post Share on other sites
debivort Posted August 2 Share Posted August 2 Given the rectangular shape of the inclusions, I would call this a "porphyritic" rock, wherein larger crystals have formed within a rock matrix with smaller crystals. 3 Link to post Share on other sites

DPS Ammonite Posted August 2 Share Posted August 2 (edited) Debivort is right; it is a porphyritic rock. Probably feldspar crystals in a fine grained igneous rock that is worn down in a river. It needs to be moved out of the fossil ID section. Edited August 2 by DPS Ammonite Link to post Share on other sites
Mark Kmiecik Posted August 2 Share Posted August 2 Very nice "keeper" example of a porphyritic rock. Link to post Share on other sites
