Denis Arcand Posted July 26 Share Posted July 26 (edited) I found what I think it is a fossilized stromatoporoid? Late Ordovician, Quebec Edited July 26 by Denis Arcand One fossil a day will keep you happy all day. Welcome to the FOSSIL ART Link to comment Share on other sites More sharing options...
ynot Posted July 27 Share Posted July 27 Looks geologic non fossil to me. 1 Link to comment Share on other sites More sharing options...
Wrangellian Posted July 27 Share Posted July 27 I'm not an expert on your formation or stromatoporoids, but seems like it could be. Does it differ from all the usual rock you find in that formation? I guess you're reluctant to cut it open or you have no access to a saw? Link to comment Share on other sites More sharing options...
Rockwood Posted July 27 Share Posted July 27 Looks like metamorphic rock to me. Link to comment Share on other sites More sharing options...
FranzBernhard Posted July 27 Share Posted July 27 At first sight, it looks intriguing. Upon closer inspection (good details in your pics!), it looks like a siliciclastic rock, so no fossil. Franz Bernhard Link to comment Share on other sites More sharing options...
Denis Arcand Posted July 27 Author Share Posted July 27 @FranzBernhard @Rockwood @Wrangellian @ynot THANKS! for your ideas, I think the only way to be sure is to cut it open, I will do that today and let you know One fossil a day will keep you happy all day.

Denis Arcand Posted July 27 Author Share Posted July 27 @FranzBernhard, it seems you are right, no distinctive feature on the inside. It's a rock ? I wonder what would create the mound-like features on its surfaces ? 1 One fossil a day will keep you happy all day.

FranzBernhard Posted July 27 Share Posted July 27 Yes, not a fossil. Sandstone or gneiss, not sure. Metamorphic rock was already suggested by @Rockwood. No idea about the features on the surface. Franz Bernhard 1 Link to comment Share on other sites More sharing options...
Rockwood Posted July 27 Share Posted July 27 Crystals formed during metamorphosis being more resistant to weathering/erosion would explain the mounds. 2 2 Link to comment Share on other sites More sharing options...
Denis Arcand Posted July 27 Author Share Posted July 27 Thanks! It won't go in my display case One fossil a day will keep you happy all day. Welcome to the FOSSIL ART Link to comment Share on other sites More sharing options...
Wrangellian Posted July 28 Share Posted July 28 I'm having trouble seeing past the saw marks but I trust you can see better in hand what it is, so I guess we have an answer. Link to comment Share on other sites More sharing options...
