Raggedy Man Posted June 24, 2018 Share Posted June 24, 2018 Looks like a highly worn crinoid stem segment. ...I'm back. Link to comment Share on other sites More sharing options...
Innocentx Posted June 24, 2018 Share Posted June 24, 2018 Crinoid stem or possibly worn ammonoid fragment. "Journey through a universe ablaze with changes" Phil Ochs Link to comment Share on other sites More sharing options...
Rockwood Posted June 24, 2018 Share Posted June 24, 2018 I think the apparent angular geometry in the central cavity is a better fit with the crinoid ID. Link to comment Share on other sites More sharing options...
JohnBrewer Posted June 25, 2018 Share Posted June 25, 2018 Not ammonoid imo. John Map of UK fossil sites Link to comment Share on other sites More sharing options...
Innocentx Posted June 28, 2018 Share Posted June 28, 2018 Found this photo in another post. It's what I was thinking when I said ammonoid. I should have said nautiloid. "Journey through a universe ablaze with changes" Phil Ochs Link to comment Share on other sites More sharing options...

The sections would have a curved shape rather than the strait profile that I see. It is difficult to be certain of it though. Link to comment Share on other sites More sharing options...

It is difficult to be certain of it though. I see this curve in the first photo, which seems to be the most straight down shot (the other shots having been taken from the same side angle). The first photo also shows more of the whole fossil. I've not seen crinoid segments that curve this way. Perhaps another straight down shot and a shot from the other, opposite side, would reveal more about this. @Michelle Sawicki Library, can you do this for us? 1 "Journey through a universe ablaze with changes" Phil Ochs Link to comment Share on other sites More sharing options...
Rockwood Posted June 28, 2018 Share Posted June 28, 2018 and the hole in the center. Circle or pentagon ? 1 Link to comment Share on other sites More sharing options...
