Ludwigia Posted March 29, 2021 Share Posted March 29, 2021 On a recent trip to the Wutach Valley I discovered a pile of fossils on a slope by the side of the road which had obviously been disposed by somebody who didn't want them any more. Among other things was a small piece of matrix chock-a-block full of various gastropod species. They all look somehow familiar to me, but I can't for the life of me figure out where they are from, what stratigraphical formation they belong to or what their names are. Does any one have any suggestions? Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...
DPS Ammonite Posted March 29, 2021 Share Posted March 29, 2021 @FranzBernhard Ideas? 1 My goal is to leave no stone or fossil unturned. See my Arizona Paleontology Guide link The best single resource for Arizona paleontology anywhere. Link to comment Share on other sites More sharing options...
fossilnut Posted March 29, 2021 Share Posted March 29, 2021 No idea. But what an outstanding gift someone left for you. Two really neat additional types to boot. Love the decorative pattern on the main group. i suspect they will be recognizable to some TFF member. Maybe the easter bunny was out early. 1 Link to comment Share on other sites More sharing options...
val horn Posted March 30, 2021 Share Posted March 30, 2021 this article may be helpful. It has a figure that shows turritella as they evolved in NA and it may help give your a time frame for the turritella in your samples.

At very first sight, it looks "somewhat" Weitendorf-like (Miocene), but it isn´t. Wrong matrix, no Weitendorf-type Turritellas. And it would have already disintegrated! @Coco, @fifbrindacier, @marguy There are other french members here on TFF who know a lot about such material, but I can not remember who they are, maybe @Coco, @fifbrindacier, @marguy know? 8 hours ago, Ludwigia said: They all look somehow familiar to me Indeed, also to me.

caterpillar Posted March 30, 2021 Share Posted March 30, 2021 Maybe Terebralia from miocene 1 http://www.paleotheque.fr Link to comment Share on other sites More sharing options...
marguy Posted March 30, 2021 Share Posted March 30, 2021 I see the question now, I was going to indicate to contact Caterpillar and at the same time I see that ihet provides an indication. 1 Link to comment Share on other sites More sharing options...

Ludwigia Posted March 30, 2021 Author Share Posted March 30, 2021 Thanks very much to everyone for your suggestions. It seems to be at least tending to somewhere in the Cenozoic.

HansTheLoser Posted April 4, 2021 Share Posted April 4, 2021 Roger, ask A. Nuetzel in Munich. I guess it is Mesozoic. Link to comment Share on other sites More sharing options...

I have an id request pending by Joachim Gründel, so I think I'll wait that out first. Greetings from the Lake of Constance.

Dr. Gründel couldn't say all that much about them since he tends to specialize on the Jurassic. However he's pretty sure that they're from the Early Cretaceous and that the smaller ones could belong to the genus Metacerithium. I sent a request to A. Nuetzel almost a week ago, but he hasn't replied yet. Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...
Ludwigia Posted April 22, 2021 Author Share Posted April 22, 2021 Still no answer from Herr Nuetzel, so I think I'll close the files on these. Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...
