Hello, Could I get an ID on this piece? Permian-aged from the Ryan Formation near Waruika, Oklahoma. It's labeled as a reptile jaw piece. Has three teeth that are laterally compressed and somewhat twisted with serrations (Apparently there are serrations only on one side of the teeth). I wonder if it's shark and not reptile at all. Pathological shark tooth perhaps? Size is a little over 1cm. @jdp

Found this on a trip to Big Brook yesterday and having a tough time figuring out what it is. The tooth is missing the tip, but appears to be quite narrow, with a strong curve that would eliminate xiphactinus as a possibility. It looks too narrow to me to be a mosasaur tooth and has no visible carinae. Is there any chance it could be a plesiosaur tooth? Thanks for the help!

I managed another trip to Aust and as I had a better idea what I was looking for managed to get a few bits of bone bed to sift through back home - one of whch was this nicely preserved piece of what I presume is reptile bone (approx 6cm long?) My guess is a partial rib (although it is completely flat, with no visible curvature), in which case given size and location most probably Pachystropheus, but I'd love to get any more thoughts.

I went to douglas point a few days ago, eager to get a large Otodus. What I did not expect to find was a skull fragment with teeth still embedded inside! None of the teeth are complete, but there is a lot of them, and it’s a pretty nice sized chunk of crocodile skull. I wasn’t even planning on doing douglas point that day, but we looked at both of the parking lots of both places, purse state, and douglas point, and I decided that zero cars was better than trying to navigate the beach with over 12 or so cars parked. There was no room for us to pull in anyways so I chose douglas point instead. The hunt started off very typically. I found a few goblins and sand tigers, some really nice bone fragments, and some busted up Otodus, one of which would have hit 1.75 if complete :(. But about half way through the trip, I found something odd. I thought it was one of the sandstone rocks from the zone 3 but it was colored brownish, so I picked it up and when I flipped it, there were rows and rows of teeth lining the bottom. I thought at first that I just found a jaw in the rock and did a little victory dance. It wasn’t until I investigated further that I came to realize that this was a piece of SKULL. WHAT?!?!? In my 10 years of collecting, I never would have thought that I’d ever find a skull. I was ecstatic! I will be taking this to the Calvert marine museum for further study and if they need this, I will give it up :(. That’s what a good scientist would do. Anyways, here are all the finds from that day. I found a lot. The whole haul: The whole haul flipped: Close up of the better stuff: I found 3 broken up Otodus teeth, a complete shark vertebrae, a scute, a coprolite with a fish scale inside, and a crocodile skull fragment. All the better stuff flipped: Underside of the skull: There are so many teeth in here! This is my first every crocodile skull, I’m now hoping to find the other pieces when I come back to this location. What a find! Coprolite: You can actually see what this animal had for lunch. This is a pretty neat fossil and would probably have been my favorite if not for the skull! Thank you for reading guys. I hope you enjoyed this trip report!

Hi, The seller seems to be upfront about a few of the fingers being enhanced and the matrix having been repaired/glued to some mason board or something. Any red flags about the rest?

I did not find the possibility to answer on pics in other albums. So, this is the link to a wonderful tooth Archaeopteryx lithographica tooth - Members Gallery - The Fossil Forum Love to know more about it, who determined it as tooth from Archaeopteryx. I would love to see a close-up, too. Do not think it is Archaeopteryx @jacob86795

Here are the two fragments I found in Ramanessin of what i believe to be mosasaur. the right one im unsure of, i still think its a cretaceous reptile. the left one, I am more certain is a mosasaur. but let me know what you think!

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)

Just found wht is it

Hi everyone. It has been way to long since I posted anything. Life has been crazy for me. I still stalk the forum everyday. Went hunting this morning for the first time since the summer. I have something that really looks like a tooth. Parts of it do and others parts does not. Really need other opinions on this one. I put it under the microscope because I just cant determine what it is. I hope it is something. Thank you for taking a look! Hope everyone is well.

Keichousaurus Fossil, is it real? Restorations?
OneLastSift posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hi I came across this Keichousaurus fossil online and was wondering if it is real or as major restorations of painted parts. Thanks!

Good evening to all my paleo peers! Tonight I’d like to share with you a selection of some of my favorite fossils found this year. I was lucky enough to spend three weeks in Montana over the summer, along with a few other fossil hunting opportunities here and there. As we hop into the New Year I'll kick things off aptly... Frog Radioulna-Judith River formation, Montana One of my all time best single fossil hunting days was spent in late June on a microsite in the Judith River badlands of northern Montana. Among the teeth of crocs, hadrosaurs and dromaeosaurs was this absolutely tiny limb bone. When reviewing my finds from this week I gathered up several of these micro bones and put them in a gem jar. I brought this minute group along with a small portion of my collection on my recent visit to the Carnegie Museum of Natural History. While exploring their collections I met amphibian expert Amy Henrici, who recognized it as the distinctive fused lower arm bone from a frog, also known as a radioulna. Yesterday I was able to take clear, close up pictures of this tiny limb on my digital microscope and subsequently posted it as my fossil friday on instagram (same username). I was excited to learn about its identity as it’s the first example of a frog fossil in my collection that I’m aware of! This little guy would have likely been on the menu for a whole host of predators, including Dromaeosaurs and Troodontids. The recent discovery of Daurlong provides evidence of a predator prey relationship between these two groups.

I think this is a snake head? I found it in northwest Missouri around Grand River. It's approx 1.5" long, 1.25" wide (widest point) and head area is .5" tall. It is rock with some quartz in there.

I found this in Northwest Missouri. It's approx 1.5" tall, 1" wide and only .25" thick. I see eyes and fangs? But then again I see lots of things in fossils and rocks that aren't there LOL! Can anyone help ID this?

Here's a tooth I bought at the gem show back in the days when Moroccan vertebrate stuff was starting to appear at Tucson and other shows. I've been meaning to show it to people for years. It's from the Kem Kem Beds (Cenomanian), Taouz area, Morocco. It's about 61mm long with cutting edges that appear to be slightly crenulated rather than finely-serrated. It's oval in cross-section on the root end but the crown becomes blade-like toward the tip so it is somewhat labiolingually compressed. I assume it's a crocodile tooth but thought it might have a small chance at being from a dinosaur. I'll hit up the "Kem Kem regulars" for comment but am interested what others say as well. @Troodon @Haravex @LordTrilobite Thanks, Jess

Mesosaurus real or fake?
Microraptorfan posted a topic in Is It Real? How to Recognize Fossil Fabrications
saw this online and I think its real but the prep is awful, thoughts?
-
Began prep on something quite special today. Though I’ll be uploading pictures once completed. I have always said, you always find your best stuff heading back to the car. That certainly can be said for this day. I’d not had much lucky all day, these days I’m looking more for stuff to add to the collection, rather than collecting for the sake of it. Couple of nice ammonites but that’s it. I then walked past a spot I had already walked past that morning, when I noticed what looked like a GIANT vert, laying amongst the shale from a recent cliff fall. Yup. It was. Safe to say my breathing was all over the place. I haven’t measured yet, but as a guess. Id say it’s around 25cm. This most likely makes it temnodontosaurus. The real beasts of the sea. If that isn’t the face of happy man. I don’t know what is.

Hi everyone! Fun story behind these. I bought them when I was about 15 labeled as "Mosasaur Vertebrae". As I've gotten older and (hopefully) more experienced I'm questioning that ID after pulling them out recently. All three are from the Moroccan Phosphates. So what do you all think? I'm leaning towards croc on the third and Elasmosaur on the other two with a slight possibility of the first being really primitive whale, but I'm not sure. Any insight is greatly appreciated as always! Vertebra 1: 49.4 mm long, 52.36 mm tall, 36.54 mm and 34.8 mm wide. one centrum in concave the other is flat. Vertebra 2: 49.6 mm long, 49.23 mm tall, 49.5 mm wide. both ends concave Vertebra 3: 48 mm long, 39.9 mm tall, 34 and 32.75 mm wide. both ends slightly concave.

Introducing Hainosaurus boubker, Last of the Great Tylosaurs.
Praefectus posted a topic in Fossil News
The unnamed giant Tylosaur of the Moroccan Phosphates is revealed at last. The great and mighty Hainosaurus is a previously unrecognized macropredator present in the latest Cretaceous (Maastrichtian) of Morocco. https://www.researchgate.net/publication/365437927_First_Record_of_a_Tylosaurine_Mosasaur_from_the_Latest_Cretaceous_Phosphates_of_Morocco Authors: @Praefectus @BrennanThePaleoDude @pachy-pleuro-whatnot-odon Abstract: The latest Cretaceous Phosphates of Morocco preserve the highest biodiversity of mosasaurid squamates anywhere in the world. Intensive sampling over the past century has uncovered at least ten genera and thirteen species from the mosasaur subgroups Halisauromorpha, Plioplatecarpinae, and Mosasaurinae. Notably missing from the assemblage are members of the macropredatory Tylosaurinae. The Tylosaurinae were globally rare in the Maastrichtian and their apparent absence has been previously explained by either collecting bias, ecological preference for deeper waters, or habitat restriction to higher paleolatitudes. Here, we describe a new tylosaurine mosasaurid, Hainosaurus boubker sp. nov., based on several partial skulls and isolated teeth originating from the Couche III layer of the Sidi Chennane Phosphate quarry near Oued Zem, Morocco. It is unique amongst tylosaurine mosasaurids in possessing blade-like teeth that are laterally compressed, encircled by enamel facets, and differentiated along the dental margin. The discovery of this new taxon in the Maastrichtian of Morocco is remarkable as it represents both the youngest species of Tylosaurinae and the first occurrence in North Africa. It has been a pleasure to work on this project and I am so happy to finally see it come to a conclusion. Tremendous thank you to Boubker Chaibi (Instagram @foussilouedzem) for discovering and donating the type material. Additionally, thanks to Carlos Espinosa (Instagram @carlost_sapiens) for bringing Hainosaurus to life. Funding for this project was provided by the Association of Applied Paleontological Sciences’ Charles H. Sternberg Scholarship for vertebrate fossil research. Thank you very much the members of the AAPS.

Found this in a load of river rock delivered to my home in Omaha, Nebraska. Tried to find where the river rock came from but no luck. About the size of a large walnut. Any help would be greatly appreciated!
