Hi there everyone. I would really appreciate your skills/opinions about if my little ''treasure'' is actually a coprolite or not. I have always believed it to be, just because it looks like a poo with something in it to me. I have forgotten where i found it, but most likely it was in Newcastle, NSW, Australia. It is ovalish in shape and appears to have a ''skin' wrapped around some sort of internal content. As I know zero about fossils, your time and expertise is gratefully appreciated. Looking forward to hearing from someone with excitement and thanks. Photos hopefully attached! Many cheers, Kazza

Found in the same layer as poo a lot of them

found in mo. Same hill side as rest

I have just found this little coprolite? yesterday. This is the second time a coprolite-like fossil has turned up in the shale from the Leighton Fm. I am not really sure on this one, though, due to the presence of crinoid stems. The fossil(s) are from the Leighton Formation, Maine; which is Pridoli, Silurian. The main reason I think it is a coprolite is because of its situation in the shale. The rest of the shale around it is relatively uniform, with no fossils whatsoever. The fossils present in it are one crinoid stem, quite a few ostracods, a very small Orbiculoidea brachiopod, and an unidentified piece of rather bluish-black material in the center, possibly some sort of shell. My main concern for its identification as a coprolite is the wide range of rather large fossils in it. I don't know what animal would have had such a diet, except possibly a very large detritivore - but I don't know of any super large ones here. The only animals that I can think of producing coprolites in this formation would be eurypterids, phyllocarids, agnathan fish, and possibly trilobites. A coprolite of this size I would identify as an agnathan fish, but I would defer to some of our fish and coprolite experts for this. @jdp @GeschWhat Below are two photos of the two different sides of the coprolite. If you would like closeup photos of some of the fossils inside the coprolite, I have some available. Just did not want to overload this post with too many photos. Thanks in advance for your help everyone!

I unfortunately have no location on this road pie as it came in an auction lot. Is it coprolite? And if so is there any indication as to what animal might have excreted it? Thank you!

So I went and had a great day out at Penn Dixie ( Devonian) this weekend. I brought home a lot of fossils I'll be happy to clean up and put on the shelf. Thankfully, My level of incompetence is quite apparent to anyone that sees me struggle, young man took pity on me and helped me ( I don't know if I'm allowed to tag him in the post). After a long day of fossil collecting, Walking back carrying back a bag that was far too heavy for me, Sweaty ,tired and dehydrated. I wander from the path to look at something that has caught my eye. It shines, it calls to me. What is it?! I pick it up and put it in my pocket. In my car it goes and to a safe little spot where all my top fossil of the day go. And there it sits in its place of honor for the 3 hour drive home. When I get home the nice little Box comes inside where open it to find all my beautiful little trilobites sitting and this, this fossil, rock , poo? Do I pick up and drive home 151 miles with a bit of sun dried poo?

Hi, could anyone tell me if this is a Coprolite ? It was found in the UK on a field a the top of the South Downs national park , along with a flint scraper and an Echinoid.

Attached pictures are of a stone I discovered in our garden after receiving a load of landscape rock, believe they cam from Colorado. This particular stone is shaped like a road apple left by a horse. It is domed with a flat side like, as I said, a road apple left by a horse. Some of the surfaces are similar to a hard gray shell; while those areas where the shell has broken away are loosely packed red, black and clear crystalyn material that crumbles easily from the stone with light touch of the finger. Any ideas?

Not all rocks that look like poop have a fecal origin. Here are a few things to consider when trying to determine whether or not you have a coprolite: 1. Location, Location, Location – If you haven’t guessed, the first and most important thing to consider is the location your rock was found. Don’t expect to find a coprolite unless you find it in geologic area/layer where other fossils are found. If you find things like bones, teeth and fish scales, or prehistoric tracks, you may just be in in luck. 2. Shape – While fecal matter can be rather free-form when exposed to the elements or when digestion issues arise, most coprolites are shaped like poo. As with modern extrusions, fossilized feces can be shaped like pellets, spirals, scrolls, logs, piles, etc. Their shape is dependent on shape of their producers intestinal and anal structure. Look for things like compaction folds and pinch marks. 3. Texture - Most coprolites are fine grained. If your specimen appears granular under magnification, it is most likely not a coprolite. There are some exceptions, such as marine creatures that feed on bottom sediments or coral. That is why knowing the location and geology of the area where it was discovered is so important. 4. Inclusions – Many times, coprolites will have visible inclusions. Things like fish scales, bone fragments, and teeth may not get fully digested, and can be visible on the surface. Some animals ingest stones for ballast or digestive purposes. These are known as gastroliths, and if present, are generally smooth. 5. Composition – Because herbivore scat tends to break a part and decompose rapidly, it rarely survives the fossilization process. So most fossil poo that is found is from carnivores. The reason for this is that their poo is usually high in calcium phosphate, the same mineral found in bone. This mineral can appear in many forms. It can be hard and dense or soft and porous. If the potential coprolite appears soft and porous, there is a quick test that is often used in the field. If you touch to stone to the tip of your tongue and it sticks, chances are, it is high in calcium phosphate and could be a coprolite. If you are not that brave, you can also touch it with wet fingers to see if it feels sticky, but this is not nearly as fun. If the calcium phosphate takes a harder, more dense form, the “lick test” won’t work. In some instances, chemical analysis is required to definitively identify the mineral composition.

I found this on Cromer beach Norfolk. It is 72.8grams 1.6 inches long Up the coast a while back a fossilised Mamouth was found surrounded by hyena droppings and I only saw a glimpse of a photo and it is similar to my find.I had a little trouble uploading photos but I hope they are enough thank you

I came upon these two things and I can't figure out what they might be. I found them in the White river formation in SD. Is it corrall? it almost has a mettalic ring when tapped, and seems alot denser than most things I pick up. Thanks for all the help!
