Hi Jack,
I will post my interpretation of the mud impressions as an additional image with that fossil. As I haven’t seen the literature, I’m relying on memory, and the Ordovician Atlas (http://www.ordovicianatlas.org/atlas/ichnofossils/). -

Hi, @matthew-croxton – Here are two Vindlandostrophia species ID guides:

7 years, 9 months ago7 years, 9 months agoHi Ronny,
I use a Voigtländer 90mm f/3.5 SL II APO-LANTHAR lens, usually stopped down to f/8 or f/9. While this lens is out of production for Nikon and Pentax mounts, it is still available for Canon. Scroll to the bottom of this page for more information on the optic. Please be aware that this lens is manual focus only, and is adjusted…[Read more]

7 years, 9 months ago7 years, 9 months agoThis ichnofossil contains what a Dry Dredgers pamphlet identifies as a scolecodont – a microfossil that is part of a marine oligochaete’s chewing apparatus. The size (shown in the secondary image) is just shy of 2mm.

7 years, 9 months ago7 years, 9 months agoI have provided an enlargement of the siphuncle. If you can provide a better ID by getting a good look at this structure, I’d appreciate the info!
-
I only know of one species of Orthonybyoceras – O. dyeri. In the same family is Treptoceras duseri. I’m not entirely sure how to best distinguish between them and I think they both can be found in the Grant Lake Fm. Any advice from other Ordovician folks? @jkallmeyer @kyle-hartshorn @bheimbrock
-
My apologies for not replying sooner. No reply for me means “I don’t know”. At times, these two were thought to be synonymous. I think that Treptoceras is more common and has a wider range. I’ll have to look dig into some siphuncle photos and see if I can tell the difference. Thanks for asking! @jbauer @matthew-croxton

7 years, 9 months ago7 years, 9 months ago@jkallmeyer Thank you very much for the ID assistance! I was closer than expected with some. I’m donating these for use at my school, so I’m very glad to have them imaged and documented prior to classroom use. 🙂
