COPROLITE

Here's another one jasoninsd

I think I have more somewhere. This one reminds me so much of shrink wood.

There is little doubt that wood often shrinks and cracks during/before petrification Randy. Especially in dry conditions.
It makes sense that poop would do the same.
The humidity and wet ground seems to bring bacteria to the equation in these parts but old wood laying on high dry granite exposures often survives and dries with such cracks and fractures.
It would makes sense that the times of the dinosaurs would be much more hot and humid. However some tropical woods are super dense and impervious to rapid rot. Take a mulberry tree or eastern cedar, they rot slowly. Trees like teak and biloba in the deep tropics are resilient to rot.
Many of the specimens you post have those type cracks in them. I don't remember seeing alligator poop, It might be a good comparison sample for dino poop. Google images provides a variety of gator poop. They are mostly if not completely carnivorous though.

I feel compelled to think James is correct in his hypothesis. I've looked at these specimens with a microscope and made positive ID for wood structure. They are undoubtedly embedded within coprolites so I don't know what else is a viable conclusion. I've never read anything about shrink wood in all the coprolite literature I've seen so maybe we've identified something new

Holy crap - fecal connoisseurs are rejoicing. Keep the photos coming.

It looks like a solid piece of pet wood. He must have wolfed that log down.

Randy, those pics you posted this morning are seriously specimen grade!!

These are amazing!
