locutus9 Posted December 20, 2020 Share Posted December 20, 2020 (edited) This is a fossil I collected at the Long Pond Road Site along the Erie Canal in Greece, New York. It is from the middle Silurian Rochester shale. Some interesting perpendicular lines can be seen along the edge of it. I have looked for other fossils similar to this one and have found nothing. The American dime is 1.8cm in diameter. Edited December 20, 2020 by locutus9 Link to comment Share on other sites More sharing options...
Darktooth Posted December 20, 2020 Share Posted December 20, 2020 This is very interesting as it looks very well preserved. I have not seen anything like it before. It will be interesting to hear what others have to say. I like Trilo-butts and I cannot lie. Link to comment Share on other sites More sharing options...
Fossildude19 Posted December 20, 2020 Share Posted December 20, 2020 Trilobite partial hypostome or doublure , I think.

I want to agree, but those vertical grooves on the upper band makes me hesitate. 1 ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...

FossilDAWG Posted December 20, 2020 Share Posted December 20, 2020 My first impression is the same as Tim's, trilobite bit, but I don't recognize the species. Don 1 Link to comment Share on other sites More sharing options...
Nautiloid Posted December 20, 2020 Share Posted December 20, 2020 Cool find! Looks like it could possibly be a piece of a phyllocarid carapace. I could be wrong though. Link to comment Share on other sites More sharing options...

westcoast Posted December 20, 2020 Share Posted December 20, 2020 I used to find these in the Silurian of west of Ireland many years ago and agree with @piranha that Bumastus is your starting point. 1 Link to comment Share on other sites More sharing options...
