There is no practical lower limit to the unit size for feces - only an upper limit. In other words, large animals can certainly make small turds (cervids) but small animals can only make turds up to a certain size. 2 Link to comment Share on other sites More sharing options...
Natalie81 Posted August 13, 2018 Share Posted August 13, 2018 I found this one on the Isle of Wight, UK. Cenomanian. Could it be coprolite? Link to comment Share on other sites More sharing options...

They must have been similar to modern cow pies. Also their thin form makes it easy for them to break apart even if they do fossilize. Their flat shape makes them really blend into the formation. I haven't seen any yet but I do look for them. Marco Sr. If you step on one and it sticks to your shoe, chances are it is not a coprolite. 3 Link to comment Share on other sites More sharing options...

For the most part, it is impossible to determine what creature was kind enough to donate their droppings. The fecal origin of many "turtle coprolites" is somewhat questionable. I have not personally examined nor read up on turtle scat. From what I understand, the siderite concretions/coprolites that are usually attributed to turtles have no inclusions, and are thought to be from turtles based on shape alone. 5 Lori www.areallycrappystory.com/fossils www.facebook.com/fossilpoo Link to comment Share on other sites More sharing options...
Monica Posted January 1, 2019 Share Posted January 1, 2019 Hey Lori! @GeschWhat I received this specimen from my Secret Santa this year - it's from northern Texas in an area that's Permian/Triassic. Any idea as to the type of animal that would have made this poop? Thanks a bunch! I hope you're having a great new year so far! Monica 1 Link to comment Share on other sites More sharing options...

GeschWhat Posted January 3, 2019 Author Share Posted January 3, 2019 Hi @Monica! The New Year is off to a GREAT start. I hope yours is as well. Unfortunately, there is no way to determine what type of critter produced a coprolite. Usually best we can do is identify whether the creature was an herbivore or carnivore and the type of prey that was eaten if inclusions are present. Other than that, we can only make guesses based on other fossils found in the same location. If it had a spiral or scroll shape, it would be pretty safe to say it was from a fish. Maybe someday we will know more. I find myself collecting scat when I know the "poopetrator" in order to put together a library of modern examples for comparative purposes. But many critters make similar shaped poop. I found this little deposit from a Cope's Tree Frog on my aunt's patio swing. Evidently, they don't digest the exoskeleton of their prey. It even contained a compound eye. Now to find a coprolite with similar inclusions! 2 Lori www.areallycrappystory.com/fossils www.facebook.com/fossilpoo Link to comment Share on other sites More sharing options...

Just wondering now, after looking at photos online - do you think the specimen I have is likely a coprolite, or do you think it's just a rock that's high in iron content? I've noticed that there are similar-looking specimens out there that ended up not being fossilized poop... Thanks again for your help!

Since I have never personally hunted in the area where this was found, I would hate to make the call. I guess I would want to know if there were other rocks with a similar composition in the area that had shapes or inclusions that could more easily be identified as a coprolite - or the opposite - larger rocks with shapes that couldn't possible be coprolites. 2 Lori www.areallycrappystory.com/fossils www.facebook.com/fossilpoo Link to comment Share on other sites More sharing options...
Mark Kmiecik Posted April 5, 2019 Share Posted April 5, 2019 Care must be taken when dealing with what appears to be a coprolite with any spiral characteristics that is found in what would have been a marine environment. Many shark egg cases have spiral markings and depending on how complete the specimen is may be mistaken for a coprolite, and vice versa. Mark.

Not at Mazon Creek -- no turtles for another 80 million years and coprolites are as common as _ _ _ _! Amphibians, giant millipedes, fish, monster dragonflies and a host of others, but no turtles. If you collect 100 MC concretions there's a good chance that five of them will contain coprolites. (d i r t) Mark. Fossil hunting is easy -- they don't run away when you shoot at them!

There is much debate as to whether they are actually coprolites, or some odd type of geologic or sedimentary structure. See this article, and this one. They have also been discussed on the Forum, before. 1 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

Dinostones Posted September 24, 2019 Share Posted September 24, 2019 In 1996, I was being introduced to coprolite hunting in Northeast New Mexico, when I found these two pieces in close proximity to one another. The larger plop, has an indentation on the side, where something stepped into it. The longer piece has obvious sphincter marks along the taper. It seems entirely possible that both pieces were left by the same visitor. 2 Link to comment Share on other sites More sharing options...
