ScottBlooded Posted November 21, 2020 Share Posted November 21, 2020 Found in the needmore formation just outside Winchester, VA puts him at mid Devonian. Only his pygidium visible but the rest of him (presumably) is still in the rock that contains the cast. The third photo here is the cast, taken at a slight sideways angle to get an idea of how it broke off from the rest of the rock. Hard to tell in the photos but the segments have alternating gold coloration, along with small spine nubs on the tops of the colored segments. I know it’s hard to determine from just his butt. Figure the order is Odontopleurida, closest match I could find was acidaspis calicera, but I couldn’t find a lot of good examples. Another thing, (and I know that this technically goes under the fossil prep board but, you know, while I have your attention) any tips on how to most carefully prep out the rest of him? It’s a fairly fragile shale material and he’s one of the trilos that preserves in a way that almost makes him seem made of the same material as the matrix, so extra delicate.

Misha Posted November 21, 2020 Share Posted November 21, 2020 Maybe Leonaspis? Whatever it is, it looks like a really nice bug @piranha Link to comment Share on other sites More sharing options...
Huntonia Posted November 21, 2020 Share Posted November 21, 2020 I'm inclined to say Kettneraspis callicera, very nice find! Take a look at this thread for reference. 3 Link to comment Share on other sites More sharing options...
connorp Posted November 21, 2020 Share Posted November 21, 2020 Very nice bug! Looks like there is definitely more there. Might be worth sending off to a professional. Link to comment Share on other sites More sharing options...

Huntonia Posted November 21, 2020 Share Posted November 21, 2020 I agree, getting a professional prep job would be ideal. Just now, ScottBlooded said: Never done that before, any suggestions? We have a few talented folks here on the forum. If you make a request under fossil preparation there's a good chance someone would be able to help.

Kane Posted November 22, 2020 Share Posted November 22, 2020 Just as a minor correction, Acidaspis callicera is now known as Kettneraspis callicera. Beyond that, your ID is spot on. A very nice find! 1 ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...

I’m currently trying to self educate on trilobites (specifically mid/early Devonian), could you recommend any good resources? Obviously trilobite.info is great for internet resources but I’ve been looking for books to read on the matter Link to comment Share on other sites More sharing options...

Let the trilo experts give you more knowledgeable guidance. They'll be coming along. 2 Link to comment Share on other sites More sharing options...
Kane Posted November 22, 2020 Share Posted November 22, 2020 By virtue of my institutional affiliation, I get all the recent goodies (and some others from some very generous trilo workers!). You would do well with the book Trilobites of New York, which has many of the similar species in your area. There are more pinpoint resources that I’ll invite @piranha to suggest for the Needmore. Oh, and for more general information, grandpa's recommendations above are very good, and I would add Treatise O to that list. 2 ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...
