Tidgy's Dad Posted December 23, 2020 Share Posted December 23, 2020 Looks like a Middle Devonian selection of mostly atrypids and productids to me. I think I can give some tentative ids, but it's half five in the morning here and I'm just off to bed. See you in the morning. 1 Life's Good! Tortoise Friend.

FossilDAWG Posted December 23, 2020 Share Posted December 23, 2020 This fauna is very similar to what I have collected from the Devonian in Manitoba. Even the color and lithology are a close match. My collections are from the Dawson Bay Formation but there are other formations as well. I will have to dig out my copy of Helen McCammon's Manitoba Geological Survey bulletin and get back to you. It might take a while due to Christmas duties. Don 1 Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted December 23, 2020 Share Posted December 23, 2020 No.1 is my favourite but I don't know what it is.Though I feel I should. 2. An orthid along the lines of Levenea? 3. Cyrtospififer? Mediospirifer? Orthospirifer? 4. Can't rememeber. 5. Pseudoatrypa. 6. Tropidoleptus 7. Really nice but don't know. Sorry, not much help. I need to do some revision over the holidays. 1 Life's Good!

I need to do some revision over the holidays. More help than myself! I wouldn't have even known where to begin having rarely collected in paleozoic deposits until recently and not having information locality to go on. Brach?#9 has several individuals among this stuff but they don't seem much detail so I didn't post it earlier. I guess I'll post it for completion purposes. These glacial erratics came from other sites. Leperditia molds? I'm not sure what other ostracods get this big. These weren't found far from the other posted stuff. These all came from Mclean County North Dakota erratics. They've been sitting in my collection for many years. #10 Link to comment Share on other sites More sharing options...

Thomas.Dodson Posted December 23, 2020 Author Share Posted December 23, 2020 And #14. As always, any information is appreciated. Do these appear similar to age as the ones already posted? Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted December 23, 2020 Share Posted December 23, 2020 Don't know 9. Yes to Leperditia sp. 10. Athyris spiriferoides? 11. Stropheodonta demissa? 12. Pseodoatrypa devoniana 13. Atrypa reticularis Yes, all appear to be Mid Devonian, though some of them also appear in other times, the group together suggest M.Dev. 1 Life's Good! Tortoise Friend.

Tidgy's Dad Posted December 23, 2020 Share Posted December 23, 2020 My entry for number 14 has somehow been deleted. 14. Spinatrypa spinosa. 1 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
Thomas.Dodson Posted December 23, 2020 Author Share Posted December 23, 2020 Very much appreciated. It's an interesting feeling having identities for glacial erratics! Link to comment Share on other sites More sharing options...
