Show us your Devonian Epizoans & Pathological Brachiopods!
Brach3 posted a topic in General Fossil Discussion
Dear all, if Devonian Epizoans (Epibionts) & Pathological Brachiopods (all the periods) are a fascinating group of fossils for you and you want to discuss anything about their paleoecology, please post your photos (specimens) in this thread.- 209 replies

Hi I recently bought a small 4cm 'coprolite' from a commercial supplier. Do you think this is likely to be a genuine fossil from Bull Canyon or is it likely to be a fake. Is there any way I could tell?

I see on the web many deferent looking specimens being sold as Dino Coprolites. From what I’ve read on the web, most of these specimens are thought to be purely geologic. I was able to purchase 14 slabs labeled as Dino Coprolites from Utah for a very reasonable price so I bought them to see what I could see under a microscope. Chemical analysis and analysis of thin sections are much better ways to approach this. The individual pictures of the below 5 slabs (one is an end cut) were taken with the pieces wet and the close-up pictures taken with my microscope were taken with the pieces dry.

Although I haven't been beach hunting much this winter (fishing was great until a few weeks ago), I rooted around for my shrimp coprolite burrows. Lately I have been finding less of the cylindrical 1-3" long burrows and more broken pieces. @Carl @GeschWhat are the experts on these things, and lately I've found more of them on the beachs than shark teeth (Covid-19 opened the interest in beach combing so more competition for teeth.) Difficult to get much resolution, even enhancing the contrast, but this is a scan of most of my collection:

I Like Poop- Mazon Creek Coprolites- A Visual Post
Nimravis posted a topic in General Fossil Discussion
Today I was looking at fossils that I have paid any real attention too in quite a while. I figured that I would try and organize some of them and I started moving containers and pulling out concretions that contained coprolites. The pieces that I was working with were larger pieces, and that is what this post will show. I have found coprolites in the Essex (Marine) and Braidwood (Fresh) biotas. Many collectors in the past would skip over coprolites, just like they did with Essexella asherea Jellyfish, but that is not me, I would pick them all up. Mazon Creek coprolites have been known to conta- 38 replies

From the album: Dinosaurs
A chunk and a slice of dinosaur coprolites bought at a nearby rock store. Species, location, and age unknown. Despite being what they are, they both have a nice red coloring. -
Hi all, I recently found the items below at Calvert Cliffs State Park (A-F) and Matoaka Beach (G-I) in Maryland (both Miocene exposures). Image scales are in inches. I'm not sure what these are. Could some or all of them be coprolites? If so, any ideas as to what kinds of animals they came from? Thanks for your help!

Hello! As a new member I am excited to learn from more experienced folks on this great forum. We found these coprolites (I think that is what they are) near the Little Colorado River, near Gray Mountain, Arizona which is about 45 mins north of Flagstaff, Arizona. They were both found on the surface. We go to this area to rock hound for jasper, agate and petrified wood, which we find in plenty. Can anyone tell me: 1. Are these coprolites? 2. What kind of seeds are fossilized? 3. Based on location and seed id, who pooped these out? Thank you very much! I am also about to post pics of what

I was wondering if this could possibly be a coprolite? Or just a rock that has formed this way over time. Found in the Rocky Mountains of Wyoming. Thanks for your input!

Collected in 1994 in Cropwell Bishop Nottinghamshire UK, some Rhaetic pyrite layer pieces from a Gypsum mine. Packed full of bivalves, fish teeth and coprolites. Focusing on this particular find, would anyone know what it may be (1st picture) 1mm scale.

I donated 20,000+ Eocene marine Virginia coprolites to the New Mexico Museum of Natural History and Science in 2015. There have been several formal presentations given on these coprolites to date and a major paper is in final review. To see numerous coprolite pictures and read about/see previous presentations check out the below TFF link: http://www.thefossilforum.com/index.php?/topic/50059-what-ate-what/& A copy of the latest poster presentation given on these Virginia coprolites at the GSA Annual Meeting in Phoenix, Arizona, USA on September- 26 replies

I could have sworn I posted this already so if it is a duplicate, please delete it. https://m.phys.org/news/2019-08-filter-feeding-pterosaurs-flamingos-late-jurassic.html They looked at coprolite associated with Pterosaurs Trackways and it looked like they were filter feeders.

After a little research I think this is coprolite. Rock on one side and something that resembles poop on the other side. See next post for reverse side. Size is 1 1/4 inch by 3/4 inch by 1/4 inch

Coprolites? Collected near scales, teeth and fish vertebras. It sticks on tongue but aren't visible biological inclusions. Your opinion please.

For those who are interested, this paper on Brazil’s Triassic Coprolites is open access till July 15th. It’s a rather extensive piece, and I must admit I could only briefly skim it, but I imagine others on here may find it very informative. https://onlinelibrary.wiley.com/doi/10.1111/let.12251 PDF version: https://onlinelibrary.wiley.com/doi/pdf/10.1111/let.12251 perhaps it might peak @GeschWhats interest?

Hello, I find a lot of what I believe to be marine fossils from the Cretaceous period on my land up in Grayson County, North Texas, but I am not certain what kind of fossils they are. Here are pictures of what I think are coprolites? Thank you in advance for your help in identification.

Likely some have already seen this, a nice little video on coprolites, what we can learn from them and their significance. Being a post from me, the video of course covers the Two Medicine Formation, I know at least @GeschWhat will enjoy. https://www.facebook.com/scifrimacroscope/videos/986351528231150/

Was curious to see what had washed up on the beach. Weather was dominated by east winds and usually north winds bring in the most stuff. From my finds it appears that a lot of sand was deposited covering, sadly, most shark teeth. Did find several shrimp(?) coprolite "burrows" (which I had not seen much until my previous trip?) @Plax @Carl @GeschWhat Found only four shark teeth- - a medium Mako, a rootless Hemipristis, a sand tiger and a broken sand tiger (initially thought it was something more interesting, the break was polished smooth by the sand). Found my second piece of skat

A friend of mine(yes, it really is a friend, not just me lol)apparently got these in a box of stuff, and they were labeled as being from mosasaurs. He asked if they were coprolites, but i don't know exactly how they were described. I told him no, I don't think any coprolites would be so smooth, even, and without any imperfections(I'm sure there are some like that out there, but that must be pretty rare. A random group of coprolites aren't going to all be like that, I'd imagine). I told him I don't really know and that id ask, but my best guess would be either gastroliths, or nodules. I don't t
