  1. Niobrara coprolite with marks

    I have been talking snarge with GeschWhat, and sent her some pictures of two coprolites I have collected over the years in the Niobrara Chalk of western Kansas. I have shown these to a few people, and nobody seems to know what caused these strange marks. The one that is marked a lot was the first I found. It was sticking out of a chalk cliff about 5 feet above the floor of the valley. The marks were on the parts of it still in the chalk, so there is no way they were added after fossilization. Years later I found another similar sized coprolite, also in the Niobrara but not associated with this one that also has very similar marks, though not as noticeable possibly due to it being badly weathered and a surface find. I may have posted this years ago, but since people come and go on here, I thought I'd give it another shot. Ramo
  2. Hello again! Finally took some pictures of the rocks I was referring to in previous posts. These are the reason I asked for help ID previous rocks. I never new what coprolite was until I tried to find a reason why these rocks look the way they do. In person, they look like they contain chunks of turtle/lizard/fish/eggs/shellfish/etc type stuff, I believe what is referred to as inclusions. But it could just be some funky conglomerate. Either way I’m hoping someone can explain why they look the way they do! There’s about 20 or so of these on my property, just grabbed some and snapped some photos. I wish I had better lighting/camera so detail could be seen. Thanks for your time in advance! And if you have any thoughts please let me know! Property is located in residential Menlo Park, California (between San Francisco and San Jose), very close to the San Francisquito Creek. some were just laying on top of the ground, others were below and found when doing some yard work digging. Easier to to see the individual parts when rocks are wet as the colors pop, as supposed to blending in as a slightly reddish brown mud. Some seem to have a “skin” if you will around them, like a layer that can be rubbed off, allthough i have noticed once i rub it off the inclusions, a couple days later the colors seem to have faded. Also many of The inclusions that stick out of the rock give the appearance that they have been scratched off or bitten off, possibly just from hitting other rocks as well. The black inclusions are the easiest to see in the photos, however they are only a small fraction of the reptilian/crustacean/fish/ i dont know shapes that you can see
  3. permian pooooooooooo

    Hey gang, here is a handful of permian amphibian and shark turds from a nifty swamp deposit.
  4. Possible coprolite? #2

    Hey guys, thanks for all the responses and info in my first post! Here is another. Located in Menlo Park, Ca. Found in yard, have been doing yard work , digging holes, weeding, etc. This was originally covered in thick, what i thought to be brown mud. I havnt removed this layer completely, you can still see a bit of it as i left some on. Its the poo brown color mud still on parts of it, the second picture shows the most of it. (best description of color I have, sorry) The one side looked like a face actually and its the only reason I decided to pick it up. After looking at it for a minute I noticed what appeared to be a shell or something of the sort sticking out the one side. Got sidetracked, didnt think much of it and put it down for about a week before I came across it again. Decided to brush/scrub off some 'mud' to see what was underneath. This was not very easy, didn't come off very well, and it also had a slight unpleasant odor, a new smell for me actually, from the fine dust that was slowly brushing off in the air. I did get it wet at one point and gave a scrub with an old toothbrush as more was revealed, as I was trying to figure what the it was. The brown stuff was not nice when wet, very mucky, but not like mud. I probably should not have removed as much as I did but curiosity got the best of me and I kept "cleaning" as it started to reveal more. The one side started to show visible, what I believe to be, decay, with burnt reds, yellows, and browns. Although again apologies, as I really am a newb to all this stuff and really dont know anything to be honest with you. I dont know how it could be turtles or what the shell type thing is or how this would possibly be on my property. and from when it could possibly be from and still be in this condition. there are many different locations of what seem to be reptile skin, and also several roundish oval turtle shell looking pieces? Theres no turtles in the immediate area. and if it is poop, theres also nothing big enough to excrete this around here. Strictly residential area, biggest creatures being raccoons and dogs but this cold come out of them. But then again who knows. If anyone could help me with this I'd greatly appreciate any feedback or thoughts! I wish the pictures were better but its as good as I can do. Let me know if theres any spot I can take another shot or two of close up or whatever. I really am curious what this is, as there are many more pieces I have questions about as well. This one just seemed more "fresh" if you will, where as the others seem like rocks with inclusions. Thanks in advance! Also, please just let me know if Im crazy and seeing things haha.
  5. Is this a coprolite?

    Hello all, Thanks for letting me post my inquiry. I was wondering if any of you could give your input on a large "rock" that I found in my yard. I live in Menlo Park, California which is about a mile north of Stanford University in the San Francisco Bay Area. Please excuse my ignorance when it comes to the fossil world. I have zero knowledge in this area, but i must say that after only a few days of investigating websites and forums I find it quite fascinating. And also a massive black hole lol.. I have spent all of my free time looking into the topic the past couple days. so many hours!! (not complaining, its been awesome!) Anyways I will attach pictures below. The only reason I think it is a coprolite is because of the many other "rocks" that I have also found on the property, about 20 or so, that fit many pictures I have seen on the internet. But this one doesn't really look like any of the others and is quite large, at least double the size of the others. At first glance I thought it to be chunk of a wood round, as i have found petrified wood on the property, at least what I believe to be petrified wood. When I picked it up I noticed that it was very heavy, probably 30+ pounds, so definitely not fresh wood as this is way to dense to be so. Gave it a knock and its rock hard. On most of the outside there are small flakes of something shiny, some metallicy and some more clear, some faintly yellow/green.. I dont know if its crystal or something else but they seem to be thin pieces of something, some layered on top of each other. What struck me at first was the green that was viewable in some spots. This is the reason I picked it up in the first place to investigate further. The one green spot is mostly white now actually. After I noticed the green I had a piece of sand paper handy and I gave a quick rub on the white part to see if more green was under it and there was. However a day later the green has gone back to white. Not sure if thats from oxygen exposure or possibly the abrasiveness of the sandpaper causing scratches which turned white with time. The outraged just looks really really old is the best way I can sum it up. There was a small section that was slightly sticks out and cracked a bit so I knew it would come of easy. Gave it a wack with a chisel and it popped off. I will attach pictures of that as well. I have scraped at a couple sections, trying to see what was inside, and it seems to be green and brown in most. Parts have a serpentine look to them, which was my second guess after wood. But the rock just seemed to be to "living" if that makes sense. There are vertical and horizontal cracks throughout some with some sort of white lining in them. I really want to crack it open as I think it might be quite beautiful, based on the weight and density. Anyways I could go on but I will just post some photos and hopefully you can help me out a bit, because at the end of the day I really have no clue and don't pretend to. Also, another question I have.. Is it possible to have undigested chances of reptiles/fish/eggs inside a coprolite? not this one, but many of the other pieces I have found seem to have pretty clear inclusions of things like turtles and other things. I could be crazy also, but some of the inclusions seem to have something like skin still on them, which after research i noticed could be just lichen, but its strange that the lichen would just be on the inclusion and be a believable color as well. There also appear to be many many bite marks or teeth marks on them. My understanding is that my part of California would have been under water, and wouldn't be possible for dinosaurs to leave the coprolite. And based off the inclusions in the other rocks, it would seem to be a water beast anyways, or possible a large bird, ore maybe just something that lived by water. but not sure because like I said my area was below the sea back then. It just seems so large for it to be from a sea creature and I would have thought if something pooped in the ocean. would not most of it disperse and break apart in the water before it sunk and was covered up? Again, i have no clue haha Let me know if you want to see some of the inlusion pieces or more1 photos of this one. Photo #4 shows what i thought to be skin on this one, but other pieces are more clear. But again I have no idea Thanks for your time and I hope that a least one of you can help me out a bit! Have a great day!
  6. Perhaps I have found something fossil or perhaps it's just eroded ironstone matrix looking like fossil.
  7. I have been finding a lot of inclusions in a batch of coprolites from the Smoky Hill Chalk that assumed were bits of cartilage. One of the newer specimens from that batch had a piece of the material in question on the surface; enabling me to view it from the side. They look like little teeth, so now I don't know what I have. I have one other specimen that has a couple of the little tooth-like structures intact (one that I posted a while back that has possible Ptychodus tooth fragments). Is this skin with denticles, cartilage, a skull part or some sort of tooth plate? As always, any help is greatly appreciated.

  10. Welcome to another microscopic look into the wonderful world of coprolites. Here we have a squished (flattened) spiral coprolite from the prehistoric floodplains that now form the Bull Canyon Formation in the badlands of Quay County, New Mexico. Today's mystery was most likely not ingested. Many times the posterior (non-pinched end) of spiral coprolites can be hollow. I may be wrong, but I think this branchy thing (for lack of a better term) slipped in after it was expelled. To me this looks like part of a branch from a delicate coral - but the poop was in fresh water. Any ideas?

  12. Coprolite?

    Hi, I'm new to the forum. I've always had a lay interest in paleontology and geology. Last week while playing golf in the Dallas-Fort Worth metroplex, I spotted this unusual lump in the rock landscape around one of the tee boxes. My first impression was coprolite with a chunk of undigested something jutting out, I circled it in red. I assume it was delivered with tons of rock from a Texas quarry and I have found other fossils in rock landscapes on a couple courses I play. I'd appreciate some more educated opinions. Thanks.
  13. Coprolite or stalagmite?

    I need help identifying this item. Not sure exactly what it is. A man from Texas told me it was the finest Coprolite he had seen in 30 years. I would like to have some more opinions.
  14. Coprolite?

    Hello, two days ago, my brother found this fossil-looking thing near his elementary school in Hamilton, NJ. I thought it was a coprolite after seeing a picture that look almost exactly like it, the same type of rock, size, and even the lines going across it. At first, I thought it was a trilobite, because of the segmented shape, a "cephalon" lobe in the front with a large "pleural lobe" in the back. But that isn't very likely (I guess), because only a small portion of my area has Cambrian age rock. The whole rock looks like it's made of even smaller rocks. This is the top view. If it was anything other than coprolite (like a fossil of a living thing), then I would say that the left side would be the front. Sorry that you can't really see the ruler. It is 1 and 1 half inches long. A better view of the segments on the top. The lobe on the left made me think it was a trilobite. I hope two pictures is enough for a start, but I will try uploading more later. Thank you in advance!
  15. I was going through a large group of very small Triassic coprolites today and came upon this. Since there was a beat up Koskinonodon tooth in with the coprolites, I'm wondering if this could be a jaw or maxillary fragment from a juvenile. The person who found the coprolites said that he found a lot of Koskinonodon teeth in the area as well some from Phytosaur, Apachesaurus, Coelophysis, Postosuchus, and Revueltosaurus. What do you all think? Jaw or maxillary? Amphibian, fish or something else? If this is amphibian, can anyone identify the bone above and to the left of the teeth? My cat votes amphibian @Carl check it out!
  16. I headed to the North Sulphur River last Friday and found a magnificent coprolite in situ in the otherwise soft gray shale. I cleaned it up a bit, but as with most fossils from the NSR, the surrounding shale largely flaked away leaving the nearly 15 pound coprolite a fairly solid mass. Coincidentally, I had found a large isolated mosasaur tooth only a few feet from the spot two weeks prior. I positioned the tooth in one of the empty sockets and it would appear to be a fit. There had been a fairly good rain in the interim that looks to have dissolved a good portion of the matrix previously surrounding the chunk. My original instinct was that it had been deposited by a mosasaur, but the teeth marks in the jaw section look more shark-related to me. Too bad there's not a Coprolite of the Month. I am guessing that I might have a pretty good shot at it. Not quite the distinction of Vertebrate of the Month, but it's a start.
  17. This osteoderm was in a box of Bull Canyon Formation (Triassic - Norian) coprolites that I have been going through for the past year. The fun thing is, I one of the coprolites in this batch appears to have osteoderm inclusions that look very similar. I have looked at well over a thousand coprolites from this formation, and this is the first time I have found inclusions such as these. Needless to say, I am super, super excited!!!! Best I can figure it is from an aetosaur or phytosaur, neither of which are familiar to me. I did send an email to the person that found them to see if she is able to identify it, but thought I would throw it out to the forum at the same time. Any assistance you provide would be greatly appreciated. @Carl check it out!
  18. I received this coprolite from a forum member a while back. It was partially coated in powdery iron oxide and didn't look too significant, so I didn't get to it right away. A soak and a scrub with a soft toothbrush revealed what looks to me like the remnants of a ray tooth plate. Now I'm trying to figure out who I got it from. Does anyone remember sending me a coprolite from New Kent County, VA? Just goes to show...you can't judge a coprolite by it's coating
  19. Coprolite

    @GeschWhat, Do you think this is a coprolite or gut contents? This is from a very soft shale and was said to have been collected from the "Kamp Ranch Formation" near Dallas, TX (although I think it must have been another member of the Eagle Ford Group based on the composition and nature of the matrix) (If anyone is familiar with these Prionocyclus-rich shales and has suggestions on which member they likely came from, please chime in). In this image, I have pointed out 2 of the fish bones (there may be more). You can also see bivalves. The fossils in this layer are isolated, so it's not like a "hash plate". Most of the fossils are Prionocyclus hyatti (?). But I found this discrete concentration of bits, and I wonder if it is a coprolite or gut contents. Maybe from an ammonite... Scale in this photo is mm. Here is a picture of a piece of the shale showing the abundant ammonites. (scale in cm/mm) Thanks for any assistance!
  20. Hey Gang, So need your opinions on this one...We find alot of nodules down here and this one has a particularly well digested lumpy look to it, more so than most. Any chance you think this might actually be a coprolite? It does have a few clam borings and along the top wrinkle you can see some irregular parallel tubes that make me wonder. All thoughts are welcome. Thanks! Regards, Chris
  21. Hello good night everyone! I'm very curious ... Generally, on our favorite auction site, these fossil coprolites are described by several sellers as: Origin is Kansas Niobrara Chalk Formation Gove county 2015 Poop Oxidized Pyrite Marcasite But they never, ever describe the age in millions of years, Period, Era ... And I already researched all over the internet, but unfortunately I did not find any information about it... Does anyone here know anything about these coprolites? All opinions are welcome. Thank you!
  22. My wife brought this out of our shed in her little work wagon today. Two of these dino poops wiegh in at about 20 to 40 pounds!!! Does anyone our there in the Fossil Forum think that these can be sold? The cost of shipping alone would be a small fortune! Just wondering. Not sure what to do with these? RB
  23. Before I post my items for identification, let me first thank Seth for allowing me to scrounge around in his fossil pit in Kemmerer, Wyoming. The experience was unbelievable and it must go on everyone's bucket list of places to visit. I was absolutely impressed with the operation as a whole, wonderful staff, easy ability to prep your finds at the quarry, and most important, excellent and abundant fossils. As I finish prepping my fish finds, I will produce a more involved topic in the "TRIP" category. But for now, any help with these items would be appreciated: 1. I was told this is palm wood. Anyway to put a more specific ID on these?
  24. Hi all, I was going through some smoky hill chalk coprolites that I recently acquired and found one with some interesting inclusions. At first I was thinking these were skull fragments, but after looking at the Oceans of Kansas site, the only thing that I could find that had a similar texture were Ptychodus sp. teeth and what looks like cartilage. I have never seen cartilage in a coprolite before. I would think it would be easily digested, so perhaps it is just bone. There are also numerous fish bones and scales, so if our poopetrator did dine on Ptychodus, it had a diverse palate. I have not seen anything similar and would love your opinions on this. Thank you in advance!
