We were looking for an explanation (such as what coprolite features you think are present), not just more pictures. Sorry, I agree with the others...just a rock.

DPS Ammonite Posted February 24 Share Posted February 24 Where is it from? What formation? Does it scratch when a metal blade goes against it? The large dark rounded structure looks like a fossil such as a bryozoan. Even see a couple of rounded things that might be crinoid stems. Sort of reminds me of a piece of Kaibab Fm. chert, but we need more info. My goal is to leave no stone or fossil unturned.

And due to the burrow holes and multiple bone fragments and the shape. But thank you for your positive feedback Link to comment Share on other sites More sharing options...
vincentB Posted February 26 Share Posted February 26 The magnification of one of the last photos shows maybe some bryozoa Link to comment Share on other sites More sharing options...
ClearLake Posted February 26 Share Posted February 26 Yes, I think there is a worn fossil in that inclusion, maybe bryozoan as suggested. But no reason to think it is a coprolite. A worn pebble with a small amount of fossil inclusion. And Arizona is a big state with varied geology, so more specific location info might help.

Mark Kmiecik Posted February 26 Share Posted February 26 The only bryozoan and crinoid predator big enough to produce a coprolite that large would be a fish, and that is not anything like the shape of a fish coprolite. Most fish would not be able to pass a chunk of bryozoan that large, at least not the type of fish that fed on them. Mark. Fossil hunting is easy -- they don't run away when you shoot at them!
