kevinnix Posted December 16, 2016 Share Posted December 16, 2016 hi all, a member of my local fossil club is wondering if the specimen he found in the bottom of a dam in Calgary, Alberta, Canada, might be a fossil, or just a mineral. The specimen is about 3 inches round. Sorry, but the 2 photos i have are only of a standard quality. cheers, kevin Link to comment Share on other sites More sharing options...
Darktooth Posted December 16, 2016 Share Posted December 16, 2016 I think this is a piece of banded gniess. I like Trilo-butts and I cannot lie. Link to comment Share on other sites More sharing options...
Bguild Posted December 16, 2016 Share Posted December 16, 2016 looks geologic to me. Link to comment Share on other sites More sharing options...
ynot Posted December 16, 2016 Share Posted December 16, 2016 Agree with geologic not fossil. Tony Darwin said: " Man sprang from monkeys." Will Rogers said: " Some of them didn't spring far enough."

Ludwigia Posted December 16, 2016 Share Posted December 16, 2016 Like darctooth says, some kind of banded metamorphic pebble Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...
fifbrindacier Posted December 16, 2016 Share Posted December 16, 2016 I agree this more look like geologic than fossil. "On ne voit bien que par le coeur, l'essentiel est invisible pour les yeux."

Plax Posted December 19, 2016 Share Posted December 19, 2016 I don't think there are igneous or metamorphic rocks in the area but guess that the river could transport something from a long way off. This doesn't look like any banded gneiss that I've seen, (not that it couldn't be). If we could get a sharply focused close up it would help.

abyssunder Posted December 20, 2016 Share Posted December 20, 2016 I could see it as a septarian concretion/nodule .

I agree; it would be useful to have more detailed images, since it seems that the green section has a phaneritic crystal structure, with concentric layers of another white specimen; just a suggestion., but since it’s similar in appearance to many other minerals, I would say, with the greek word, that it’s “deceitful” (apatite) Link to comment Share on other sites More sharing options...
