Dean Ruocco Posted April 16, 2023 Share Posted April 16, 2023 Thought Id share some of my finds today from the Shawangunk formation! The beds I investigated today are stratigraphically the highest in the Shawangunk I've looked at for eurypterids. After looking through a dozen shale packets one bed caught my interest, after digging for about 5 minutes I realized I was in a new horizon. What differs from this horizon then the more basal Eurypterid horizons in the formation and this layer is the size of eurypterids, and the absence of Parahughmilleria maria. I spent only about an hour of digging before calling it a day and leaving. The specimens below are a few of many eurypterids I collected today. Top: disarticulated Erettopterus globiceps. Bottom: Hughmilleria shawangunk, before cleaning and then photographed under 6 Link to comment Share on other sites More sharing options...
Kane Posted April 16, 2023 Share Posted April 16, 2023 I'm no eurypterid expert, but I'm not quite seeing anything here. It would thrill me to be wrong, though. 1 ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...
Dean Ruocco Posted April 16, 2023 Author Share Posted April 16, 2023 They're hard to make out, but they're there. Maybe this will help. 2 Link to comment Share on other sites More sharing options...
Kane Posted April 16, 2023 Share Posted April 16, 2023 Yeah, to my eye, this looks like wishful thinking to me. Let's allow some other folks to weigh in as I could be very wrong. 1 ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...

Here's two more close ups, bottom tail and thorax, these might help make it out too. 2 Link to comment Share on other sites More sharing options...

FossilDAWG Posted April 17, 2023 Share Posted April 17, 2023 I can see bits and pieces of exoskeleton but not really anything that jumps out. I think it is there, but it's likely one of those situations where in the hand the eye/braIn can see more than a photo an capture. Maybe a photo with the light coming from an oblique angle to use shadows to bring out texture would help. Also it might help for the specimens to be dry, as when wet too much detail is obscured by reflections. Don 3 Link to comment Share on other sites More sharing options...
Dean Ruocco Posted April 17, 2023 Author Share Posted April 17, 2023 Some more photos of the specimens not under isopropyl. The top is the Hughmilleria and the bottom Erettopterus, one photo is a close up of the gnathobase. 6 Link to comment Share on other sites More sharing options...
KompsFossilsNMinerals Posted April 17, 2023 Share Posted April 17, 2023 (edited) I can definitely see it, the telson is by far the most defined part on the plate. Edited April 17, 2023 by KompsFossilsNMinerals 1 1 Link to comment Share on other sites More sharing options...
Nautiloid Posted April 17, 2023 Share Posted April 17, 2023 Awesome finds Dean!! Definitely seems like a productive horizon, those are by far the biggest Gunk Eurypterids I’ve ever seen 1 1 Link to comment Share on other sites More sharing options...
RJB Posted April 17, 2023 Share Posted April 17, 2023 Definitely something there. Segmented even. Not sure what it is though. RB 1 Link to comment Share on other sites More sharing options...
Kane Posted April 17, 2023 Share Posted April 17, 2023 I think I can see it now. Very interesting piece. 1 ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...
Carl Posted April 17, 2023 Share Posted April 17, 2023 I may be seeing something as well. But it still might be a face in the clouds. Do you know of any papers that have photos of similar specimens from this site? 1 Link to comment Share on other sites More sharing options...
Ludwigia Posted April 17, 2023 Share Posted April 17, 2023 I can make out something(s) too, but the preservation is so unique and obviously strongly mineralized. It really is "gunky" Never seen anything like this. 1 Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...
