COPROLITE

Nice! Kinda reminds me of Tiffany stone.

Exactly. 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

Friends, I wish you all a merry Christmas and commemorate the occasion with some of the finest from my collection.

So pretty and colorful, would make nice ornaments on a Christmas tree.

Merry Christmas,Randy, those are some amazing samples!

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 just watched NOVA'S - Alaskan Dinosaurs

Duck billed dinosaurs lived there, appeared to eat vegetation during spring Summer and fall, Rotten wood during the winter.

An interesting presentation.
