Hello, I found this bone cluster in a Miocene era beach deposit on the east coast of the South Island New Zealand. Appears to be ribs of some kind, 5 in total. Perhaps some sort of dolphin? Any help identifying the type of animal this came from would be much appreciated. Scale is in inches. Thanks!

Was at flag ponds today looking for fossils in the Calvert formation. This looks like a cetacean rib fragment? Dolphin/porpoise? Thanks all.

So this was one of my first fossil finds from last winter on the Oregon Coast and I still need help identifying it further. It was tossed up on the rocky shoreline one day after a winter storm in the Stonefield Beach State Rec area (Central Oregon Coast). I've sent photos to the Burke Museum's ID dept along with a few other museums that's offer opinions on fossils based on photo's and they've all said its definitely a rib, and but the debate is now between a Baleen/Whalebone or the Steller's Sea Cow. I've gotten mixed opinions from several museum experts but I would like to know or see if anyone else has come across ones like this on here and maybe has a more definitive answer. Thank you for taking a look! Specs: Weight: 3.7lbs Length: 15" Width: 3.5" Depth: 2"

Been a little while but made it out to my hole and found some goods. Would love some insight as to what the rib bone?? May be from. Enjoy and thanks for any input!! <;^><

What is this? Please someone tell me what this may be. Found in the low country of Summerville, South Carolina

Hi, this is a bone block from port Mulgrave in Yorkshire, is the exposed bone Ichthyosaur, and if so is it identify able which part? My uneducated guess is rostrum or ribs. Is this fossil something that could prep ok?

This is found at Yunnan with Keichousaurus. Is it a rib bone of a Triassic marine reptile? It looks a bit too "curved" to me.

Hello everyone, I'm new to the group and very excited. I live on our ranch in northeast Wyoming and find many fossils. This one is one of the better ones I have found. Pictures are from the first find to now after some work. Hoping someone can help ID Fossil.

Found near Lake Huron Ontario. I can see the symmetry and the darker pieces on top and that they coincide with the curved spacing below. Hard to see in pics but I’ll do my best to show. I pointed out the two less obvious in the possibility it help in identifying due to the structure etc. The other is the lighter grey square that is more obvious and visible. Thank you

Hello! I'm a new member and I was hoping I could get some second opinions on some Kem Kem fossils I'm thinking about purchasing. I've only collected American species, and have been recently interested in bones out of the Kem Kem beds. I've stayed away thus far because of the stories of composite fossils and Frankenstein pieces, but I've come across a couple that I thought were interesting and fairly priced. Was hoping I could get some other thoughts before moving on any of them (wanna make sure they aren't composites or areas of fill look weird). I've attached pictures of three specimens I'm looking at. Any help would be greatly appreciated! 1) Spinosaurus Vertebra 2) Spinosaurus Rib I think this one is what it is, prep work doesn't look the best, but just wanted confirmation I guess. 3) Carcharadontosaurus vertebra (transverse processes) I was wondering if I could get help on confirming the id on this one, not really sure what carcharadontosaur vertebrae are supposed to be like. Centrum is missing, not sure if that's important for the id.

This fossil is from Guanling, Guizhou of China, of Triassic Formation. Many marine reptile fossils were found there. This one looks like a rib bone of a marine reptile?

Went on a wild fossil hunting trip today out on private land in the Dinosaur Park fm. and found something that I’ve since reported to the Tyrrell. My best guess is a partial hadrosaur tail. The specimen is about 3 feet long by 1.5 feet wide. There was no other associated material nearby but there may be more of this dinosaur under the surface. I’ll also post a few of my favourite surface finds for today. I have a before and after photo of a vert, a large partial rib and some tyrannosaur teeth & a croc tooth.

Hi, i went on a trip to my new triassic spot and found something which reminds some sort of a rib trace on a marine bed. Look at the bottom of a rock Found near Chorzów, lesser Poland. Can you tell me what's that?

Hello, Can anyone take a look at this rib piece, please and give your thoughts? It is sold as a spinosaurus rib. It is from Kem Kem and measures 21 inchs x 3 inches x 1.9 inches (at it's widest points). Interestingly, it also has supposedly three predation marks which seller suspects was made by a Carcharodontosaurus. So, if someone can look and confirm that it's a spinosaurus and if they are predation marks as opposed to natural wear or damage with tools during extraction, that would be excellent. Seller also says that there are hairline stress fractures and resin stabilisation on one end which was very fragile is the only restoration. They will be in a 2nd post shortly. Edit: Uploaded

I know it's a partial (rib I assume?), but it would be great if there's any way to identify this beyond just a chunkosaur. Two Med Fm. MT If there is, if you can describe what you are looking at as diagnostic I would greatly appreciate.

A few weeks ago I decided to take the kids to my local park. They are building houses in this area and completed a new road which made getting to this park much quicker. Now instead of going way around it's only about a mile from my house and a much more direct shot. On the drive to the park I looked over to my right and saw some red/orange soil. The only formation in this area with that color is the Woodbine formation. "Odd," I thought. "The nearest Woodbine outcrop on the geological map is miles from here." I told my kids we were gonna make a quick pit stop for 10 minutes or so to explore and pulled into the site. If you've never hunted the Woodbine before, you're missing out. That is if you like torture. Everything is one of 3 shades of brown and finding anything, even an oyster can be a pretty big deal. So as I was walking I saw something odd partially uncovered in the dirt. It was white, black, and was striated. "Well that's odd looking." I put my hat down at the hopeful object, walked to the trunk of the car and got my handy dandy screwdriver, walked back and dug/pried the bone up out of the sandstone. I looked down in shock. I was staring at bone, but not just any bone, based on the size this has to be dinosaur bone. . I was instantly flashing back to the conversations I had with my friend earlier this year. He has forgotten more than I ever hope to know. Dinosaurs have never been found as far north in the Dallas/Fort Worth area as my hometown I was told. So the odds of finding dinosaur bone this far north just didn't seem to add up. It’s probably just croc I was thinking. I grabbed the kids and got them into the car and drove to the park. While they played I sent pictures to my friend, who immediately called me. He confirmed my suspicions, way too big to be croc. It was definitely Dino. A few days later we met at the site. The biggest concern: was it was trucked in from another site? A likely and probable scenario that happens all the time around here when construction starts. We went and looked and nope this is all original Woodbine. The huge sand and iron bedrocks made it plain that this stuff wasn't trucked in from out of town. This was the original source. The stratigraphy telling us a beautiful story of an area once composed of sand dunes and river deltas and then repeatedly ravaged by forest fires. So not only had I found a random outcrop of Woodbine where it's "not supposed to be", I'd then randomly stopped at the right spot at this massive site, and then walked right towards the dinosaur bone at this anomalous site. Sometimes it's clear the fossil gods are just smiling down on you. There's just one tiny/HUGE problem though. The bulldozers had already been there. So the bones have been scattered and thrown all over the place and they look like, well like they've been pushed by a bulldozer. This is a blessing and a curse. The bones would have never been found if not for the bulldozer as beforehand this was a pasture. But also it seems like the bulldozer operator really had it out for these bones. They've been through some things. Some terrible, horrible things. So they're ugly, hideous even. But not too ugly that I can't love them and give them a good home. So I went back a few days later and spent a good 3 hours at the site. After several hours of finding nothing at all I began to think that maybe finding the bone was just a one off. I persisted through and was rewarded with finding an interesting bone that was later identified as the top half of a caudal vert. My spirits lifted and I continued on then finding a tiny shard of bone. Not quite what I was hoping for but I'm not gonna look a gift horse in the mouth. I pressed on the last hundred feet hoping to finish that side of the site and i noticed a rock. Yeah just a rock, one of millions out there, but something about this caught my eye and I still can't explain why. I picked up the rock, turned it over, and I was then looking at a wonderful spongy porous structure. While a definitive statement cant be made on this bone, it seems to be a solid match for the end of a lower limb bone. Now full of glee and Christmas Cheer in November, I went home to clean up and gawk at my finds. A few days later I return, this time it wasn't quite as successful. I found another bone shard (meh) and a nice Cretalamna shark tooth. Pretty darn cool find if i might say so myself. Then I keep pushing on and find this little fella lying on the surface. Broken in two just an inch apart. Still no clue as to what part this one is from on the dino. After a break of a few days and doing some research on my finds I return this time with my kids. We spend roughly an hour or so at the site and then decided to call it. Not a single thing did I find. As we head back to the car I tell the kids, "Hey I wanna check this side out real quickly. The last 3 times I've come here I've wanted to check it out but never do." The kids hop in the car and buckle up and I go to explore to see if it's even Woodbine or if it's another formation. Well turns out it is Woodbine. I walk right up to a large bone peeking out of the ground, with two smaller pieces next to it. This turned out to be the superstar find of the bunch. After digging it out, taking it home, cleaning it up, chatting with it, giving it a name (we decided on Woody) I had a few ideas as to what it could be. I sent pictures to my friend Bradley who I jokingly call the Woodbine Wizard because he knows so much about and finds SO many things in the Woodbine. In fact he's the one who trained me on how to hunt in the Woodbine. He looked at it and right away said, "Dude, that's a caudal vertebrae!" A few days later he and my other buddy David came over to my house and the Wizard showed me his perfect caudal vertebrae which we used to compare to what I found. And he's right, I had indeed found what had been my local fossil Holy Grail. Now granted, I would have liked it to have looked a little prettier. But I found a dinosaur vertebrae in my hometown, and a mile from my house! Yeah, I'm not gonna complain about that. So as I mentioned my 2 friends the Woodbine Wizard and David, come out with me and we take a gander. Let me take a second to tell you how amazing these two dudes are. They come from out of town and want to visit my site to help me find more. They tell me, "anything we find goes directly to you." It's my site and my dino and they're just excited to help me out. Let me tell you guys, life is good when you can find some solid dudes like that to be your friends. So we spread out and check the area near where the vertebrae was found. David and I struck out that day but the Woodbine Wizard struck again!. He picks up a PERFECT segment of rib. Initially we all thought it was a modern rib it was so perfect. Absolutely crazy the difference in preservation. Makes me wonder how long some of these other fossils were sitting out exposed to the elements. Or maybe the bulldozer driver doesn't hate ribs as much as he hates vertebrae, limb, and pelvic bones. We'll never know. He also found a beautifully hollow bone preserved in a concretion. Whether or not this is theropod, bird, fish, or what I have no idea. Thanksgiving break, has struck and no school for the kids or teaching for me. So what is the first thing I do with my day off with the kids? That's right! Make the long one mile drive to the site. After an hour of finding a whole lot of nothing, I barely catch something out of the corner of my eye. It is thin and barely exposed. I try to pick it out and it doesn't budge. Okay, I say to myself. I call over my kids (AKA my Camera Crew) and I start digging and they filming. It took a couple of minutes but I end up digging out a scapula blade. Then nearby I find a dozen or so bone shards that had washed down the hill, presumably from said Scapula. At this point I finally email the local university. The response I get is what I thought it would be. The gist was: Thanks for letting me know! Shame it was bulldozed. Keep looking and good work! This is an exciting response for me which you'll see towards the bottom of this article as to my plans for this dino. The next day the Woodbine Wizard shoots me a text, he's going to be in town to see his brother and ask if I am up for a quick hunt at my site. Pssh, does a fat puppy hate fast cars! (In case you're wondering they do indeed hate fast cars). It's misting but armed with hot cocoa for my kids, we brave the weather and it paid off. I find a bone and turn to shout to my buddy, who literally at the EXACT same moment yells out me, "Dude! Bone!" As you might have guessed his find is way better than mine. I found a generic chuck of bone from who knows what, and he finds a beautiful piece of bone set in a larger piece of rock. It turns out this bone is the capitulum to leading into a tuberculum where it broke off. That's fancy talk for it's the straight part at the base of the rib where it connects to the vertebrae. Then a few minutes later he finds another bone. This one has been heavily compressed and fractured. This one I'm not sure on the ID or if we ever will know, but of all the ones with an unknown ID i think this one has the best shot of being identified in the future. So that's it. Today (the day before Thanksgiving 2020) I spent 3 hours at the site and found 2 pieces of coprolite. Not bone or teeth but not nothing either. So you're also probably wondering how I'm able to give an ID based on something that looks like it went through a blender (or in this case, a bulldozer). Well luckily the bones I found give us a rather solid ID. The convex and concave nature of the pubis ventrally and dorsally, the exact match of the scapula regarding shape and angle, the same cross section in rib, and shape of the caudal vertebrae. I've also had a friend who is an expert on the Woodbine look at it as well as a paleontologist from the local university and they also concur. There is also a real lack of diversity of Woodbine fauna (and Appalachia in general it appears). But even more so in the Woodbine. I believe there was a paper by Main in 2013 that stated essentially, if you find dino here in Dallas Fort Worth in the Woodbine, it's probably Protohadros. So that helps to really narrow down the contenders. But the neat thing about Protohadros is that it's a fascinating blend of Iguanodontid and Hadrosauroid characteristics. This shows in the bones making it quite unique without a real possibility of another potential match. So there you have it! That's why I feel fairly confident labeling this Protohadros byrdi. So with the local university deciding it wasn't scientifically important, this allows me to keep it. For those of you that don't know I run a traveling education program called Dino Bo. I do it here locally and I generally stay in the area. This will allow me to keep it and use it as a display for teaching kids here in the community. The impact it will have on children and future generations here in the local community cannot be overstated. The plan is to have a nice display made showing all the bones and their location on the dinosaur. I'm hoping to raise money at some point in the future to pay to prepare a few of these bones for this display. This will further help to reach one of the goals for my program, to get kids interested in science and get them outside. Having a dinosaur found in the very town these kids live in will do wonders for those goals. I'm sure more will be found and I'll continue to update this post as more is found. So stay tuned folks!

Found this on a beach with some shark teeth and other bone fragments. Most of the bone around there is very worn and tumbled, making it impossible to ID. This piece however has some interesting features and could possibly be identifiable. I'm thinking its a piece of the top end of a whale rib? Anybody recognise this as something else, large terrestrial mammal maybe? Thanks

Found in Green Mill Run creek on 8/21/2020. Unsure if it is whale tooth, some type tusk or Bone. My original assumption was Sperm Whale but some have thought maybe tusk??

I’m not sure what I have here, my best guess is a portion of tusk or rib. As always, I appreciate everyone’s knowledge and help! I’ve created a light box and started adjusting the exposure to help with quality photos. Thanks

I posted in a trip report a few weeks ago that one of my boys found two big fragments--including the joint--of whale jaw in a cliff fall from Calvert cliffs. The assumption of jaw was based on what seemed like a good comparison to a jaw on fossilguy.com plus overall shape. But a commenter suggests that the joint is maybe not flat enough to be from a mandible and that this could really be a rib. So I'm looking for any second opinions. We would really like to get a proper ID, especially as my son wants to fill in the missing segment and make a single piece out of the two pieces for display. Because of the way they came out of the fall, although they were with each other, we aren't 100% sure of what the orientation of the two pieces ought to be with respect to one another. I have put the two pieces in a few different configurations just to show what each might look like. Having a proper ID would really help. Any whale experts, please have a look and let me know what you think.

This caught my eye and I'm lacking ice age material. Before bidding, I thought it best to double check it is mammoth and not horse or bison or something. It is 35 inch along the curve. It was found in the North Sea by fishermen. If someone can take a look, that would be great. Thanks.

Got out last week with my boys for a late afternoon trip to Calvert Cliffs to try a new spot. The beach was not very productive, yielding just a few smallish bull and tiger shark teeth. It seemed to have been worked over pretty hard before us. So we quickly turned our attention to a very sizable cliff fall at the tide line. Just looking over the surface, it didn't take long before boy #1 spotted what turned out to be a complete rib fully exposed. (Not 100% sure exactly what from but, I think, porpoise.) It was fragile and ended up coming out in three pieces, but we got the whole thing. On close inspection, it seems it also might have some predation marks. Then, while we were still working on that, just around the corner boy #2 yells out about something big. On the next chunk of cliff fall, also down low, he spotted a really nice piece of whale jaw also totally exposed! We got that out and also recovered the joint, although there is a missing piece in between. Still an awesome find! (The jaw is very solid, so we'll have to learn how to reconstruct the gap and make it one big piece.) We couldn't find any other part of it, unfortunately--we were all hoping for the skull. Just a little while later, on the next big chunk over, another collector pointed out a tiny surface of bone that he generously offered to my boys if they wanted to do the work to get it out. It turned out to be a really cool atlas vert from a porpoise (I think). It was extremely fragile, too, and in a couple of pieces that we'll have to glue together (any tips?), but another neat find. Then, just for good measure, boy #2 digs out a really nice tuna vert. (We added a 2nd, smaller one later.) This was all in maybe a 30-foot stretch. How no other collectors saw any of this stuff--and it was clear many had walked right by it all day--is a mystery. And to top it all off, on the way out with our bone haul, boy #1 spots a sweet croc tooth in the wash. It's funny that we set out to find some big shark teeth, and found almost none, but still ended up with maybe our best fossil trip ever! Enjoy the pics. And if anybody wants to confirm or correct ID's, please feel free.

It was initially being sold as plesiosaur when I inquired about it, but seller says it was mislabelled and is pliosaur--which, if accurate, even better! But I am dubious over Pliosaur ID because I don't think I've ever seen any Morocco pliosaur fossils up for sale. But, if anyone can take a look and let me if A) It looks legit and B ) Whether you think Pliosaur or plesiosaur is accurate, that would be great. 80 million years old, from Morocco. 17 inches along the straight edge and 10 inches along the bottom. Thanks for any help!

Hello all. I am back with a couple fossil Id questions. I got a few things in a colection that was given to me from a ranch sale. Anyway this is the first question I have. Found supposedly in south Dakota 30+ years ago. Im thinkig a rib but that all and pretty much a guess. Any help would be much approciated.

I was searching the gravel bars in the Brazos River just southeast of Houston almost every day last week before the storm hit this weekend. Now the water's too high to look, but I found a pretty good assortment of fossilized Pleistocene aged bones during my trips. Most of what I've found have been fragments that are totally unidentifiable, but a handful still have some significant features that could lead to an ID. These two are both rib bones, but that's about all I know. The first one I initially thought was from a modern cow due to how clean it was, but after picking it up it was clear that it's definitely a fossil - it's mineralized all the way through and has a decent weight to it. The only animals of that size that could produce such a large rib that I can think of off the top of my head would be either bison or hoses. The second bone also looks like a rib, but a lot smaller than the first. It has two deep grooves on either side that seem to match up with pictures I've seen of the origin point in deer and horse ribs where the bone begins to branch away from the vertebral column. As always, any help would be appreciated!
