I think there's some good features in above specimen to interpret dung beetle activity. I'd like to see what you guys think and if you see what I see. Any comments?

Big piece of tree branch - hadrosaur passed a log Yes indeed, and on the bottom photo in particular it looks like an explosive was planted at the core of the branch and blasted sections outwards creating spaces to be later filled with bluish chalcedony. A few pages back I think jasoninsd mentioned it was like chewed up carrots and that makes perfect sense to me. I'd like one of you to enlighten me as to what mechanism is causing some of these twigs to "explode" apart leaving spaces in the middle. It's certainly a common theme we are starting to see as more specimens are sawed in half. It reminds me of looking at maps of continental drift. I also notice what appears to be dung beetle trails paralleling the outer surface and some of them terminate with what looks like a plug of fossilized beetle dung. The main one that caught my eye is on the upper photo where you can see a tunnel going from three o'clock to one o'clock where it appears to end with a poo plug.

RWA3006 Randy, this is probably not related to what you are talking about. I remember one of the documentaries talking of hadrosaurs eating dead wood and ingesting other insects. Have you ever suspected any other insect activity such as termites which might work on the wood itself and not the yucky poo part that the dung beetles are so fond of?

Rick, I think that article was quoting some research by Dr. Karen Chin who was the first to my knowledge to find crustation shells within coprolites. It was my good fortune to also find similar evidence last summer to build upon her discoveries. You bring up a concept that has not been on my radar as far as looking for bug damage upon the wood itself. I'm familiar with borer holes in much of the pet wood in Wyoming's Blue Forest and even have specimens. I need to keep my eyes peeled for this in coprolites and have neglected to do so up until now. Thanks to your comment I'll be watching. I have to wonder about possibilities of bugs working on the wood pre and post ingestion too.

Here's some Blue Forest wood peppered with big holes, mostly filled in with whatever.

I like it when you ask questions like this...but I would like it even more if I ever had anything intellectual to add for a reply! LOL The best I can do is say things like, "This is one of the prettiest poop pieces I've see you post!": Rick, I think that article was quoting some research by Dr. Karen Chin who was the first to my knowledge to find crustation shells within coprolites.

RickB jasoninsd to tell you the truth I think we've only scratched the surface of what waits to be learned about these oddities. Much of my inspiration comes from guys like you and many others who contribute on this thread. It's so cool that RTH is becoming an awesome repository for so much knowledge and I think Tommy is wise to create a backup to this forum to preserve its content.

I agree that RTH has become a fantastic repository. However, I suppose this thread would be classified as a fantastic suppository! (Sorry...couldn't help myself...and they can't all be knee-slappers! LOL) Sorry for the double post (anyone who's paying attention). These were posted in the wire-wrapping forum...but they definitely belong in this thread...

Some of you know I used to be a logger and had a saw mill. When cutting logs that had been infested with bark beetles I found countless bore holes in the wood that were usually packed with beetle dung. Many of these tunnels were in a helix pattern. I feel confident that's what we see at 4 o'clock in this photo.

Some are very bland and hardly earn a place on the shelf except to illustrate the wide range of appearances they have.

I found a coprolite deposition scenario that may interest you Randy. It suggests that a group of dinosaurs of all ages were corralled by high water on top of some hills and did their business there being surrounded by rising water(suggesting the Biblical flood or a flood). They were making deposits at rates of up to 80 turds per square yard as if tightly packed together (and perhaps in an accelerated rate fearing their pending doom of being drowned !). In Argentina silicification is so rampant due to the vast volcanic ash fields. The deposit of feces was then silicified in place with their flat bottoms pointing down suggesting their original deposit placement location and deposit patterns. hmmm. There are many new scientist that are finding merit in the Biblical flood. This article is one of many other similar subjects in a video catalog. www.icr.org/article/digging-into-fossil-outhouse/A PS: "The Chañares Formation also left another surprise. Not only did this rock layer contain concentrated areas of fossil dung and the bones of large herbivores, but it also held the remains of a fossil ray-finned fish and crocodile-like reptiles." Could it be the crocodiles were feeding on the drowning dinosaurs ? Could have been a yum-yum moment for those denisons...Just like rising lakes attract fish feeding on fresh morsels as the water rises into dryer land.

Interesting read of the Original paper, not sure I'm on board with the "Institute for Creation Research" interpretation.
Abstract
Defecation in communal latrines is a common behaviour of extant mammals widely distributed among megaherbivores. This behaviour has key social functions with important biological and ecological implications. Herbivore communal latrines are only documented among mammals and their fossil record is exceptionally restricted to the late Cenozoic. Here we report the discovery of several massive coprolite associations in the Middle-Late Triassic of the Chañares Formation, Argentina, which represent fossil communal latrines based on a high areal density, small areal extension and taphonomic attributes. Several lines of evidence (size, morphology, abundance and coprofabrics) and their association with kannemeyeriiform dicynodonts indicate that these large synapsids produced the communal latrines and had a gregarious behaviour comparable to that of extant megaherbivores. This is the first evidence of megaherbivore communal latrines in non-mammal vertebrates, indicating that this mammal-type behaviour was present in distant relatives of mammals and predates its previous oldest record by 220 Mya.
