Long overdue to post about some of my NC finds from earlier this year! First up was a very exciting trip to the NC Triassic to look for a variety of plant fossils, which were my first Mesozoic plants. Beautiful white coloring on some of them as well, the matrix is extremely soft (you can easily scrape it with your finger nails) so I've done some experimenting with how to best consolidate them without damaging the visual effect. Not a ton of variety at the site, but they are abundant and sometimes surprisingly well preserved. I have found Otozamites hespera and Otozamites powelli, as well as a few other kinds of plants. I also disturbed a "hibernating" lizard, initially I was concerned that my digging had injured him, but after a some time in the sun he scampered off seemingly no worse for the experience.

I found a Mosasaur jaw in a shop and wanted to know if it appeared legitimate. I have seen others that seem much more fake, but as they are one of the more commonly faked fossils , I thought it would be best to get a second opinion. Sadly I only have one photo.

So I found a few things at Myrtle Beach and I'm looking for some help in ID'ing them. I love looking for fossils but am not sure on things and I love the help I've gotten on this site so far. And any help with these is appreciated. The ruler is in inches. . . . 1: I thought this looked similar to a whale ear bone? Admittedly it could just be a rock but I wanted to post here and get some opinions. Getting photos of something black and shiny can be difficult but I could take more if needed, and maybe find better lighting. 2. At first I though alligator tooth but then I learned that mosasaur teeth have been found in this area also, so now I'm not so sure. Either way I love it. 3. I was thinking dolphin tooth but obviously it's broken so I'm not entirely sure. 4. And I thought I'd throw this one here too. When I saw it in the water I thought I was going to be picking up a cucullaea steinkern, but this is what it was. I thought I remembered seeing something like this online somewhere but I really have no idea, unless it's just a piece of some bone. So there they are. Any information about any of these would be much appreciated. And I could post more photos of any of these.

Howdy all, Just bought this mosasaur tooth from the Pee Dee Formation of North Carolina. Seller has IDed it as Prognathodon and I'm wondering if that is valid or if it could be something like Tylosaurus (I looked at tylosaurus teeth from that area and the patterns in the enamel seem to match). Either way I'm overjoyed to finally have a mosasaur tooth from that region of Appalachia's ancient coast.

Real or fake mosasaurus beaugei tooth
ruminate posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello everyone, I've been offered this these "mosasaurus beaugei" tooth. teeth. Is it Are they really from this species? Or did the seller made a mistake identifying it them?

From the album: Texas Campanian (Cretaceous)
cf. Prognathodon sp. Campanian (Ozan fm) Texas I'm not the best with tooth ID's, since most of the mosasaur teeth I've seen in person come from basal Plioplatecarpines, whose teeth are mostly indistinguishable. But, realizing this broken apex from a much larger tooth lacked fine striations and had a faint anastomosing texture made me suspect a mosasaurine origin, as opposed to the most common large mosasaur from the Ozan - Tylosaurus proriger. @pachy-pleuro-whatnot-odon was kind enough to walk me through the ID points and converged on indeterminate Prognathodon sp., and paleontologist Mike Polcyn gave the same opinion. Prognathodon is not described from the Ozan formation, making this an exciting find. There seems to be an elusive giant still lurking Texas's most iconic formation.-

I have decided to cash in my IRA and put the money into this rare, baby Mosasaur, I feel in the long run, with appreciation of the rare piece, I can beat the 16.78% return I had last year in the stock market. I am impressed at how robust infant mosasaurs were. They were obviously strong swimmers from birth! In the off chance, that there may be a small amount of repair; I am posting it here for opinions.

Mosasaur jaw with shark- and replacement tooth?
Jurassic_Nature posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello everyone, I was wondering which parts of this rooted mosasaur tooth are real. There is a second tooth in it which looks like a replacement tooth and next to it there is also a shark tooth. Can you tell if the bones of the jaw are real? I thought the bigger tooth could be glued on the root, like it's often the case with mosasaur teeth from morocco. And why is there a shark tooth in the bone? Any insight is appreciated.

Hey all, I bought this tooth years ago before I really got into fossil hunting myself but never actually got it to an ID. The label says it came from Oued Zem and the matrix seems to fit. There seem to be some repaired fractures. I have no experience with mosasaur teeth and researching a bit has only got me more confused regarding the ID. My (rather uneducated) attempt: there seems to be a curvature towards on mesiodistal plane pointing towards Mosasaurs. It has no serrations, but there are facets on it. Mosasaurus beaugei? Looking forward to your thoughts! Oh length of the crown is 5cm.

Hi. I bought this Mosasaur tooth about 8 years ago, and never tried to find out what it is. (I was too young) I was thinking probably Beaugei but I am unsure. The one thing that makes me sceptical is the fact that it appears quite small. Could it potentially be a juvenile?(Sorry for using the carpet as a backdrop, if that doesn’t work.)
-
I have a couple of these, this is the best specimen. I think they are from a mosasaur but only because they were found on the NSR. There are two indentions/holes that don't show up that well in the picture. The first picture shows the indention the best, there is a corresponding one on the other side. I apologize the lighting didn't make that more clear. If it helps in identification, I can retake pics.

Hello, everyone! Below are a few finds from the North Sulphur River and Post Oak Creek, and I’d love to get some help with identification. The ruler is in centimeters. 1. This first picture includes two mammal teeth (top two)(fossilized or no?), ???, and a small bone that appears to be fossilized. these were found at Post Oak Creek. 2. This bone was found at the North Sulphur River. 3. Nautilus found at NSR. Could anyone help with identifying the species? 4. Jaw fragment? Found at NSR. 5. Coprolite? It appears to have fragments of bone(?) in it. Found at NSR. 6. I found this tooth at NSR a while back, but someone recently IDed it as Latoplatecarpus (mosasaur). I can’t find too much literature on Latoplatecarpus; could anyone give me more information on this tooth and the animal it comes from? Thank you!

I believe this is also part of a Mosasaur, but unlike the 100 other vertebrae I have, this one is concave on both ends. All of the other are convex on one end and concave on the other. It does not appear to have been broken off on either end. The piece appears agatized all over which would suggest that it was not broken )at least to me) If this is from a mosasaur, is it a vertebrae, or some other part of the animal?
-
I'm fairly certain this is a mosasaur vertebrae. Found on the north Sulphur River near Ladonia, TX. Like most items found there, there is some damage caused by tumbling down stream.

I believe I have made quite well with collecting Moroccan mosasaurs, so I wish to set my eyes for new goals. And first US mosasaur material is already heading its way. I have been hoping to learn more about American mosasaurs in general and also basic tooth characteristic of more common species. Only one Im relatively familiar with is Tylosaurus proriger. With Platecarpus tympaniticus only by few articles. I managed to find information about most formations where material seem to come from, but not Ozan fm. What species were present besides Tylosaurus proriger? Thanks for replies.

Hello, all. I browsing online on online auction site and came across these “Mosasaur vertebrae.” They are in a set, and are fairly expensive to me, as I only get pocket money. I was clarifying to see as to whether they are real. They have been around a bit, so I am not sure as to whether that is a bad sign or not. I can upload more images if needed.

I need help with a couple of ID's.... The first one is a shark tooth, from the east coast of the USA - most likely from the Meg ledge. I'm not sure if it's a Carcharodon or Isurus tooth. The root shape looks more Isurus-ish but I'm not 100% which is why I'm asking here. The other one is an awesome Mosasaur tooth in matrix (Moroccan in origin, if that wasn't obvious haha)... does anyone know the genus of this tooth? It doesn't look like the typical Prognathodon teeth often seen in natural matrix. The other fossils within this matrix have me very curious too.... can anyone ID the shark tooth and other random fossils? There is a good size chunk of bone in there too. The hourglass(ish) shaped fossil might be a vertebra ...?
-
This tooth looks bit like one of Xenodens calminechari, so I would like to get opinions could it be one or perhaps something else. Marocco, Oued zem. Crown H: 1.0cm, L: 1.0cm, W: 0.6cm.

You may or may not know that I have been obsessing over finding a mosasaur vertebra and tooth. I am lucky to live in Texas where fossils are plentiful in some areas but the most productive mosasaur area is still 6 hours drive from me. So I don't get there often and the few times I have.....no verts or teeth for me. I am not complaining (too much) because I have found other great things in the North Sulphur River, but not the mosie vert or tooth of my dreams. I am lucky to have friends who hunt there regularly who feel sorry for me and give me verts and even a lovely big tooth. But I DIDN'T FIND THEM. I do know that mosie stuff can be found in Central Texas where I live (thanks to @Jared C and his amazing adventures) I know they can be found (although very rarely) in our local creeks and such. So of course I keep an eye out while hunting but with no real hope of finding them. But I hope anyways! Which brings me to today....which I count as part of my birthday weekend (birthday was Friday, but you know.....weekend still counts! ). Went out on a little fossil hunt to a new site that a friend told me about...lots of baculites (which are relatively rare here in Central Texas) and lo and behold.....I FOUND MY VERT! And not two feet away....a little tooth! Mother Nature decided to gift me not just one, but TWO of my bucket list fossil finds today! Granted, they are pretty busted up and the tooth is not complete, but WHO CARES! I FOUND A MOSASAUR VERT AND TOOTH practically in my own backyard!!!! Turns out this little exposure is Ozan Formation and I can't wait to get back out there again....after a good rain! And, to top it off, found a complete ammonite in addition to some lovely gastropods and about a billion baculites. It's no mosie in situ, but I'll take what I am gifted. Thank you Mother Nature!!!

An odd new genus and species of Maastrichtian mosasaur: Khinjaria acuta
Jared C posted a topic in Fossil News
Yesterday, Longrich et. al published a new genus from late maastrichtian of morocco. Texas's very own Mike Polcyn is second author on the paper. The paper establishes tribe Selmasaurini to describe the clade consisting of Selmasaurus, Gavialimimus, Goronyosaurus, and now Khinjaria. As you can see - it's an odd mosasaur. It's thought that Plioplatecarpine diversity receded as the Cretaceous ended, so alone on the basis of it's age, Khinjaria is unusual. But, it's also very large for a plioplatecarpine, at 8m (26 feet), and has unusual skull morphology: Short snout, big teeth, and tiny eyes. I'm having trouble getting the paper to open, so I'll just link the wikipedia instead. https://en.wikipedia.org/wiki/Khinjaria

Hello, everyone! It’s been a while since I’ve been on this forum, but I was finally able to make my way back up to Ladonia this week to hunt a little. I didn’t walk too far from the bridge and mostly just surface-searched through gravel bars; unfortunately, I didn’t fulfill my dream of finding a mosasaur tooth, but I did find some other cool things! (Please note that all measurements are in centimeters) 1. My favorite find today was this Xiphactinus tooth. I found it just sitting on top of a submerged (but very shallow) gravel bar. 2. I accidentally found this point after just picking up what looked like a black rock in the water. I’d love to learn more about it; I was thinking perhaps a Gary Point? 3. Next up is a tooth(?) that is so worn down I’m not even sure if it’s identifiable, but I thought I would put it out there in case anyone had any ideas. I was thinking perhaps Ptychodus, but someone suggested to me that it could possibly be Globidens. Any thoughts? 4. Fish bone? 5. Mosasaur vert? This is an unfamiliar shape to me so I’d love some insight. 6. Another mosasaur vert. 7. Bone fragment #1. Not sure if it’s possible to identify this, but it had a distinct shape, so I decided to just post and see. 8. Bone fragment #2. Also not sure if this will be identifiable. That’s all that I have for right now!

"Gracie" the mosasaur was finally freed from her 90 million year old South Bosque Member of the Eagle Ford Shale "prison" today. Partly exposed before her discovery on Fossil Day 2023, she is 4 meters long, complete, and fully articulated - although part of her tail and trunk washed downstream on October 5, 2023. A good part of that float has been recovered. A trip report is following when I get the energy to update my ongoing report after the last 5 straight days of excavation. Thanks go out to @Jared C, @JohnJ, @GPayton, my wife Susie, daughter Angela, Stephen Cruse, and many others who helped - especially Dr. Mike Polcyn of SMU.

hi I recently wanted to find a Tylosaurid tooth from Morocco, but I'm confused about the tooth morphology of this ID. Because I found that some teeth described as Tylosaurid had very distinct protruding prisms (likes figure 3 and 4) on their crown surfaces, while some teeth were indeed relatively smooth (picture 1 and 2). Which one is correct?
