Koopyetz Posted July 15, 2014 Share Posted July 15, 2014 Fossil found among rocks collected for border along house. Soil littered with rocks of various sizes. Unsure if sample provided is from formation in area or deposited from past glacier activity. Is it ammonoid gastropod or ? House is located in area as described to me as middle devonian hamilton group , moscow formation made up of menteth , deep run and tichenor members.

Auspex Posted July 15, 2014 Share Posted July 15, 2014 It looks like a nautiloid cephalopod, which one I cannot say, but there are many that are contemporary with the age of your strata.

Herb Posted July 15, 2014 Share Posted July 15, 2014 my guess would be gastropod, doesn't really help much does it.

Missourian Posted July 15, 2014 Share Posted July 15, 2014 (edited) To my eyes, it looks like a gastropod. I think I'm seeing surface shell detail on a raised spire. If the coiling is not in a plane, than it definitely is a gastropod. Edited July 15, 2014 by Missourian Context is critical. Link to comment Share on other sites More sharing options...
Bob Posted July 15, 2014 Share Posted July 15, 2014 Looks to me like a Gastropod possibly platyceras Link to comment Share on other sites More sharing options...
BobWill Posted July 15, 2014 Share Posted July 15, 2014 (edited) Welcome to the forum. Interesting fossil. I agree with gastropod but just too beat up to say which unless you knew the site where it came from and made comparisons with other material from there. What look like septa are probably just what's left of ornamentation on the far side as they don't appear in the early whorls. Also as Missourian said it's rare to see cephalopods coil in a moving plane. Edited July 15, 2014 by BobWill Link to comment Share on other sites More sharing options...

Auspex Posted July 15, 2014 Share Posted July 15, 2014 I guess what I was taking for septa are external ornament?

Fossildude19 Posted July 16, 2014 Share Posted July 16, 2014 I guess what I was taking for septa are external ornament? Chas, That's it, exactly. Some of these were highly ornamented, and it looks like some differential weathering has taken place.
