Fossildude19 Posted September 9 Share Posted September 9 Nice death assemblage of Mucrospirifer mucronatus. Likely Devonian aged. Maybe Lower Devonian. 1 Link to post Share on other sites

Tidgy's Dad Posted September 9 Share Posted September 9 Very nice. Mucrospirifer mucronatus is limited to the Middle Devonian, I think. 1 1 Link to post Share on other sites
nylaker Posted September 9 Author Share Posted September 9 Thank you all for that quick response! We've been piling rocks for the wall on our shoreline for 60 years, with an occasional shell imprint, but nothing of this size and complexity. Absolutely fascinating. Link to post Share on other sites
Jeffrey P Posted September 9 Share Posted September 9 Really nice piece. Congratulations on your find. I agree with Tidgy's Dad, that it is Middle Devonian, likely Panther Mountain Formation. Though there is Devonian aged rock in your vicinity, I strongly suspect this was brought down to your area by the glacier. 1 1 Link to post Share on other sites
