RWA3006 Randy, I just did a google image search of the top half of the first photo and images of petrified wood came up. Mr. Hadrosaur was definitely eating his veggies. ![](https://i.postimg.cc/25Cg9hsq/Capture.jpg) ![](https://i.postimg.cc/JzS5GLqR/Capture.jpg)

I knew many viewers of this thread would see it too. I think it's amazing how we are learning these dinosaurs often ate big chunks of wood that would not be entirely digested. I feel that by looking at a lot of specimen photos many of us here are getting a good eye for interpreting old turds.

RWA3006 Gorgeous specimens, sir! Love this thread, thank you for making it happen! I visited south of Hanksville twice last year and never made it to a dig spot because there were so many specimens EVERYWHERE. It was amazing, we picked up lots of halves, quarters and naturally-shaved slabs.. Upon further inspection back home I noticed how some pieces appear to have small bone fragments coursing through them. (?!?) I reached out to ask was my friend in Utah who introduced me, he said he's never seen any indication of bones in them (while I have 100+ examples). I pondered this and realized that all the examples I have are from fractured rocks, while my friend only collects whole specimens (like yourself). On all the whole specimens I found they aren't visible due to the thick rind I polished a few to play around with and it appears that when the bone runs into the agate it loses definition and simply appears as a clear streak inside. I can post a few pics to support (if that's ok) but wanted to ask you, our resident Co-Pro;)- have you found indications of bones on/in coprolite? Specifically, slabs that naturally shaved apart? If this was covered between pages 36 and 150 please accept my apologies- I'm still catching up, slowly but surely:) Sincerely, Patrick

We have mysteries to solve and things to learn together! All the coprolites I've found come from vegetarian dinosaurs, mostly hadrosaurs judging from skeletal remains that are found in the coprolite layers. I've never encountered bone in one yet but have found crustacean shells.

Thanks for the photos Patrick, those are really interesting. As far as I know I've never found carnivore coprolite and it's fairly easy to identify those that I find as herbivore sourced because of the distinctive cow pie shapes. I'm stumped about the white substances in your photos, and I think it would be interesting to see one of those flats polished. I've seen a lot of agate that has a white rind or streaks which is a type of oxidation, and your photos remind me a little bit of that, but I have to say I don't really have any insights to offer. I wonder if you could have the white parts tested for phosphorus. Can you look at them under magnification?

I haven't looked under magnification yet... now I'm extra motivated to take em to my local university and see what they can tell me. I'll post any feedback I get from them here. Thanks all!
