Here's an interesting coprolite piece that had flakes struck off it by Amerindians. I like that one.

Nice one. Some areas look like pet wood.

Another type of roughage/nutrient.

What's weird is it appears that the limb split and parted, then chalcedony formed in between the sections. Would that have been petrified prior to digesting or after? Based on the size, it seems like that would have been a fresh twig rather than petrified gastrolith.

Based on the size, it seems like that would have been a fresh twig rather than petrified gastrolith. I'm guessing it would be petrified along with the rest of the coprolite because it appears it was broken up during the ingesting process which would be hard to do as an already petrified entity. I while back I would have doubted this idea but research by Karen Chin is revealing that sometimes these critters ingested chunks of dead/decayed wood. We shouldn't find that so surprising because many animals such as elephant, black rhino, horses readily eat dead wood. Horses like to eat the thick bark off cottonwood trees, and in fact in old times that's what they were fed to get through the winter. When I lived on a ranch we often had to replace the top rails of corrals which the horses chewed up, an annoying habit called cribbing.

So now I am looking for dung beetle evidence and wood in the coprolite. Thanks Randy.

What would be interesting to know is whether there is a critical size for wood to end up identifiably petrified. Small or overly masticated wood may break down too quickly in the poop. Large or more solid pieces of wood may have a better chance of surviving the fossilization process to become identifiable chunks of wood within the coprolite.

When I find them with broken edges like this I can usually bet they will be beautiful inside.

It's quite rare for me to find them like this and they could pass for Moroccan agate.

Has a really good brecciated look to it.

Nice Randy RWA3006. Don't forget to use the Lysol after your photo shoot. That second photo would look great in a litter box frame. So much for the early morn humor - time for me to scat.

Randy, that first one is pretty awesome! The second one doesn't even look petrified. It looks so fresh I can almost smell it.

First picture is awesome! Second picture looks like poop. What's interesting is the two photos are of the same specimen, front versus back. I don't know what I did with the other half after I cut it.
