Hi guys, these days i was given this claw coming from kem kem as a birthday gift. This fossil was sold as a theropod claw, but it looks anything but to me. I assumed it could belong either to a sauropod cub or to a strange lizard not yet described. What do you think? THANKS XD

This fossil was found at Liaoning at the same formation as Psittachosaurus. Any idea what is that? A primitive turtle or a dorsoventrally compressed Psittachosaurus? The locals called it "turtle-back dragon" in Chinese.

Found this earlier today... was wanting to know if it's a turtle humerus? 4" in length. Found on a river gravel bank. Never really paid much attention to turtle pieces... now I see them everywhere.

Hello! I have found these fragments on the beach over the years in North Carolina. I don't remember exactly which beach each one came from, possibly the Fort Macon area. I think they are all pieces of turtle or tortoise shells, but if anyone can help pinpoint these any further that would be cool! Thanks!

I had went on a hike last year out in the badlands here in southwest Wyoming and stumbled across this turtle nestled up on a small peak. About a month ago, I took the same hike to retrieve what I had found ( horrible hike to pack a 50lb turtle on my back ha) and I was seeing if anybody might be able to tell me more about it by chance?

With my limited time in North Texas before my move south, I decided to revisit my favorite sites as opposed to scouting new ones. The NSR is a classic locality, but I had never actually gotten to check out the famed red zone for myself. Yesterday, I made the drive to the fossil park. I was supposed to hunt with a couple others, but it unexpectedly turned into a solo hunt. I won't complain though. The vast river emanates a magical aura that is uniquely felt when you're exploring on your own. The primary goal of the day was to snag a decent specimen of the red zone ammonite, Trachyscaphites spiniger! In an attempt to beat out the stiff hunting competition and high afternoon temps, I arrived to the site in the early hours around seven. Unsurprisingly, I was far from being the first car in the lot. As luck would have it though, none of the people there before me had their sights set on the distant red zone exposures. It's a long and taxing trip that only so many people (the crazy ones) are willing to undertake. After crossing under the 2990 bridge, I took in the view and tried to visualize where the destination might be. It was quite daunting, but the journey of a thousand miles begins with a single step. Red Zone Road It was gonna take a lot of walking to reach the mouths of the red zone creeks, so I tried to keep the gravel hunting minimal along the way. Nevertheless, my eyes were still scanning the ground around me and the vigilance steadily began to pay off. After a few Enchodus fangs and a Carcharias holmdelensis tooth, I came across the first prize of the day. Cemented together in red zone matrix was a mass of turtle shell that I had never before seen a similar specimen of. It has some good weight to it and cool three dimensional character. I don't know enough to identify it to a genus assuming that's even possible. I believe Archelon and Ctenochelys are known from the NSR as well as other genera I'm sure. Articulated turtle shell fragments in red zone matrix Some time later, I came across an interesting bone fragment that I don't have much of a clue about. The texture seems like fish. It has pronounced ridges running longitudinally and a U-shaped spongy cross section. I held onto it in case it might be something cool. Mystery bone Here and there I came across various red zone ammonite chunks to whet my appetite. None of them were keepers in part because I had high hopes for what lay ahead. Maintaining my steady pace brought me to the mouth of the first creek I had circled. Yesterday's 25 foot rise was still draining and the sound of rushing water filled the air with occasional thuds from falling shales. In the high cliffs I could see a distinct red band of matrix slicing through the grey shales. Tracing it with my eyes, I followed the line upstream until it was within reach. It was absolutely filled with phosphate chunks and nacre-covered Baculites. After a short time, I locked onto a Trachyschaphites that was just poking out. Excitedly, I threw out my tools and began excavating. My enthusiasm was quickly washed away as I realized the chunk sticking out was just a chunk. This sequence of events repeated itself along the entirety of the creek and before I knew it, I was exiting with a bag of assorted Trachyscaphites pieces. The only interesting things to show were a beat up red zone mosasaur vert and some snails. Red zone mosasaur vert Gastropods from the red zone Now the temps had crossed into the 90s and beads of sweat were covering my face. Wanting to take a break from the red zone, I began a thorough search through the massive gravel bar outside the creek. It took awhile to warm up my hunting goggles, but eventually I spotted the first keeper of the bar: A big ole worn mosasaur tooth. Sadly, it was sliced in half and had chunks busted out of it. Not too long after, though, I got it a smaller, much more complete friend. Likely Tylosaurus proriger After these mosasaur teeth, I scored what I like to call a "pseudo-mosasaur" or its other name, Pachyrhizodus. It was pretty easy to spot the difference since a little bit of bone was attached beneath the crown. Still a cool little fish tooth. Pachyrhizodus I'm not very good at spotting artifacts despite having spent many hours in the creeks of Austin. Now and again though, I manage to blindly stumble my way into a killer point or two. Wedged into the sand beneath the receding waters, was the unmistakable base of a Gary. Haven't found one of these before, so I was pretty happy to add this NSR classic to my collection. Gary in situ Gary point The last and most interesting find of the bar was a huge chunk of Xiphactinus jaw! It seems to match up exactly with the very distal end of the lower jaw. Within two matrix-filled tooth sockets are a couple of emerging teeth. Distal end of a Xiphactinus lower jaw with a couple of teeth. Finally, it was time to set my sights on the creek across the river. To my knowledge it doesn't have a name as it is quite small. The disappointment of my previous red zone expedition set my hopes low. Although the tree cover was nice, with it came swarms of mosquitos and some sort of biting fly. I spent most of my walk through it flailing my arms trying not to become a walking buffet. The red zone was much better exposed and I quickly spotted a couple of Squalicorax that sadly weren't keepers. There were many Trachyscaphites fragments to waste my time, but at long last I ran into exactly what I was looking for! With careful swings, I worked the heteromorph out of the shale and quickly stored it safely in its own private Ziploc bag. With the primary objective met, it was time to quickly evacuate the mosquito hellhole and return to the safety of the sweltering sun. Trachyscaphites spiniger heteromorph (my favorite ammonite). There is a significant crack that hasn't completely split. Hopefully the b72 will hold. It was about 4 pm and I was close to my limit. There was another spot further ahead known for arrowheads that I wanted to see, but I was saving that for the people I was intending to meet (no cell service so I didn't know plans had changed). It became apparent no one was coming, so I gathered my bucket and pack for the long trek home. The adrenaline of fossil hunting had definitely carried me through the day. The river now seemed endless and every step of foot sucking mud taxed me more and more. After retracing my route at home, it seems I river walked at least 5 miles! As I crawled into my blistering hot car, I told myself one red zone hunt was enough for the rest of my life. But after a good night's rest and cataloguing my finds, I'm ready to go again . I guess we'll see how I feel next summer. Thanks for reading!

I found this today on a river gravel bank. This is the 1st of these for me. I figured it was turtle so I looked online and I think it's a (forgive me if I tangle it up) a Carapace bone (which is top of turtle shell) but also a Nuchal bone which would be the top front of the shell just above the neck? And it's made up of scutes? Can this shell pattern be pinned down to what type of turtle? It is solid. Size is 2.5 inches × 2.75 inches.

I'm trying to identify a couple fossils that were labled as turtle fossils. Does anyone know what they are?

Would love some background on this. I've seen Green River Formation fossils with big turtles before but never a tiny little fossil turtle. Unfortunately I don't know the provenance or the age. Any ID on this one? The scale in the background is centimeters. Thanks.

I apologize for the in hand photos, but I was getting the best lighting here and I believe if they are identifiable at all these photos will be okay. I found these all snorkeling in the Santa Fe river in north Florida the other day! My guesses are as follows: A - turtle? B - some type of ankle bone? C - mammal tooth D - really not sure but it looks like a socket from some large mammal maybe E - really not much to go off here for me personally, it was just such a large bone chunk that I had to take. Would be very interested if anyone has any guesses!

I can clearly see some sort of microfilaments inside but asides from that I'm stumped. Found North of edmonton eroding into the river. Any thoughts?

Hi, Am I correct that this toe bone from HCf "near Glendive" Montana is from a turtle? Thanks!!

I'm interested in a few of these turtle fossils supposedly found in the Neuse river in North Carolina. They are also labeled as Cretaceous. Do you think this is accurate or could they be from another age and or locality?

Four weird little pieces from Gainesville fossil hunting. Guess for 1 is maybe turtle? 2 is very dark and was hard to capture the detail on top even with a dslr and flash, maybe a fish part? The bottom two both appear to be some type of teeth to me, whether that’s crocodilians or cetacean I’m not sure. I’m not even certain they’re identifiable!

Hey everyone, new here, but hoping I’ve come to the right place! My family just got back from tooth hunting on shark tooth island and found these too and wondered how we could confirm what they are and if they’re just ordinary or could be extraordinary!

Hello, does anyone know some of the described soft shell turtles from the Lance Formation? Or a paper of some of the turtles. I am interested in a soft shell turtle from the Lance so any help is appreciated. Thanks.

Hello! I've found this today near Swanage, Southern England in the Purbeck group - early Cretaceous. The initial thought was turtle rib but I'm not particularly familiar with turtle anatomy, so I thought I'd run it by the group. The location has yielded crocodiles, turtles, Iguanodontian dinosaurs and some mammals. Sadly, had a break in it when freeing it from a bigger block, but recovered most of the pieces. Note that it is flat, thin, does not appear to taper or pinch along the length - not clear from the photo but it's uniformly 0.75cm thick and before the break about 8 cm in length. Note the ridge at the right side end in the image - it would flare out slightly from this point if this is the head. The portion at bottom (the side of it) has a broken edge so would be slightly broader when complete, and the same may be true of the other side which is still in matrix. Any help to even a genus level would be great!

Hi all, me again, I wanted to share a closeup of the bone fragments that I found in Ramanessin to see if I could get them ID'd further since I know how the brook tends to make fake fossil bones i want to check that the ones I found are real fossil bone 1) the big one, i think it might be a cretaceous turtle shell, it passed the burn, and the lick test. 1A) I believe these are also enchodus jaw fragments. 2) 2A)

Found in Moab, Utah in a creek or stream. It's hard to get pictures showing the true shape but this can't be just another rock.
