Being as dinosaurs probably weren't "picky eaters" (to a point), I wonder how much of the gravel ingested could have come from dirt clinging to roots. When a plant is pulled out of the ground intact, there's generally dirt still clinging to the roots. Since the dino's couldn't shake the dirt loose, ingesting it would have been inevitable. (Thinking out loud! LOL) Totally possible in my imagination. I really don't know what to think. There's also good evidence they ate logs of rotten wood with crustaceans according to Karen Chin, a prominent scientist on the subject.

The Strong Iron Red is ONLY with the Dung Beetle Tunnels! Fabulous! WHY? Ground waters bearing iron entered the tunnels before silification?

Now that we have well over a hundred pages of specimen photos it has become obvious that beetle burrows are highlighted with more mineral colors than the rest of the turd material. I wonder if the tunnels allow more volume of water to pass through which in turn allows more minerals to be deposited within them. I think it's a solid hypothesis that there's a relationship going on in this scenario.

Maybe they have some kind of chemical residue on their exoskeleton that changes composition, PH, something like that.
Is it 100% sure it's burrowing beetles and not some kind of worm, larvae, etc.?

Exoskeleton residue wouldn't surprise me at all, and as far as I can tell it's a combination of adult dung beetles and their larvae. I base this guess from modern dung beetle behavior of which I am not any kind of expert.

Early dung beetle tunnels are red, later drying cracks are blue?

It looks like there is some manganese present.

Why do the turds always appear from the outer appearance as geodes? Did the creators of the crap drop turds to that of a horse? Dung balls if you will

In the science of turdology we know that when it comes to herbivores there are two basic classes, grazers and browsers. The classic example is the difference between the black rino and the white rino, one having a frontal mouth specialized to grazing grass and the other has a prehensile lip for grasping twigs in browsing.
Their dung is different also, with that of the browsers being coarser with twiggy roughage. The outer shapes of browser's turds are predominantly firm ball shaped blobs instead of runny splats like a cow.
Speaking of cows, we now get into ruminants, who have multi compartments in their stomachs that act as redigestion devices. Ruminants are very efficient at processing their food and can survive on much poorer vegetation than non-ruminants like horses. That's probably where the saying, "eat like a horse" comes from because horses need more feed to survive than cows, one being a ruminant and the other not.
I doubt that the hadrosaurs were ruminants and the evidence shows that they were mostly browsers because of the identifiable twigs and coarse diet in their coprolites. I think the grasses probably weren't fully evolved by their time too. Gastroliths are present in their coprolites, so in taking all this evidence together I suspect their digestive systems were like some kind of hybrid bird/lizard/mammal contraption.
Anyway, that's my best speculation at this point.

Excellent Report from RTH's Master Dungologist!
