Kane Posted October 1, 2017 Share Posted October 1, 2017 Not enough information. Doesn't look like anything more than geologic to me. ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...
Rockwood Posted October 1, 2017 Share Posted October 1, 2017 Their appendages do bifurcate, but I agree more evidence than this would be needed. A telson drag would be a start. Link to comment Share on other sites More sharing options...

abyssunder Posted October 1, 2017 Share Posted October 1, 2017 It looks like a cracked chert nodule with lots of conchoidal fractures, like those from the Holy Cross Mountains, Poland. A good reference regarding to this will be Z. M. Migaszewski et al. 2006. Middle Oxfordian–Lower Kimmeridgian chert nodules in the Holy Cross Mountains, south-central Poland. Sedimentary Geology 187: 11– 28 . Please read the document.

Fossil-Hound Posted October 2, 2017 Share Posted October 2, 2017 That doesn't look like horseshoe tracks as those are tiny and side-by-side. Here's a horseshoe crab with tracks: Do or do not. There is no try. - Yoda Link to comment Share on other sites More sharing options...
Rockwood Posted October 2, 2017 Share Posted October 2, 2017 To get there, as I theorize, you would need to zoom in on the track made by the tips of one appendage on a firmer substrate. The full y shape would not be made because of the lack of depth. Too far a stretch to call an ID, indeed. Link to comment Share on other sites More sharing options...
Rockwood Posted October 2, 2017 Share Posted October 2, 2017 Light bulb on ! The line in the center. Telson ? In that case you need some y shapes on the sides. I now think this is closer than anyone has realized. Link to comment Share on other sites More sharing options...
Rockwood Posted October 2, 2017 Share Posted October 2, 2017 It's still a little (perhaps a lot) sketchy, but claw marks,(feeding?) with telson drag through freshly disturbed sediment ? Link to comment Share on other sites More sharing options...
