Recently purchased this at a local show. It looks good to me I just want to double check.

Found last week in SE North Carolina, Campanian,Tar Heel formation. I was thinking Deinosuchus but has globidens characteristics also. total length is 2 in., Dia. is 1in. 1/2 in round cavity, length of enamel alone is 7/8 in. Can someone confirm what it is? Thanks

I recently saw a globular mosasaur tooth up for sale labelled as Globidens phosphaticus. I am conscious, however, that a number of teeth labelled as Globidens are in fact from Igdamanosaurus, Igdamanosaurus aegypticus in particular, so is this tooth actually a Globidens? Thanks in advance for any guidance Othniel

Is it possible to id between Moroccan Globidens phospaticus and Igdamanosaurus aegyptiacus teeth? Or does the separate teeth go as Globidensini indet?

I think North Texans will relate when I say that now and then, the urge to take a drive out to the NSR and spend the day hunting some Campanian gravel bars can spontaneously take complete hold. I had one of those moments just after the series of heavy rains and powerful winds our region encountered some days ago. Previously, my luck with weather at the NSR had been rather poor. Each time, the temps were either nearing a hundred degrees or only just above freezing, making a full on adventure crossing muddy waters and crawling atop unshaded gravel beds too much to handle. I had yet to experience a proper adventure at this historic site, so I decided that this week would be the one where I changed that. Luckily, my friends @PaleoPastels(Lari) and Cole where kind enough to invite me out to their special spot along the river. After waking up bright and early, I got in my car and followed the rising sun. After jumping out of our vehicles and exchanging brief greetings, we quickly slid our way down to the shale bed and beelined for the first bar. Cole has a bit of an aversion for water, so he stuck around at the entrance for most of the day while Lari and I got our clothes wet hopping from bar to bar. The weather and water temp were absolutely perfect, and the lack of footprints assured us it would be a productive day. It's not often you beat the crowd to a place as popular as this! Although I maintained measured expectations coming in, the sheer variety of strange and interesting fossils/artifacts that are known to come from this area kept me on my toes from the outset. When we arrived to the first bar, we started off strong, picking up a variety of shark teeth. Lari had an eye for them, immediately spotting a few super big Scapanorhynchus texanus, a staple of the Ozan Formation. Despite my protests, she was very generous in donating a few to me due to my limited NSR collection . Finally one I spotted myself! Scapanorhynchus texanus Scapanorhynchus texanus of the day. Some may be Carcharias samhammeri as I am still working on differentiating the two. In between crawling the gravel, I did some sifting which yielded a few interesting specimens including Squalicorax kaupi, Cretalamna sarcoportheta, Carcharias samhammeri, and a vole tooth which I will ignorantly assume to be Pleistocene in age. Cretalamna sarcoportheta, Squalicroax kaupi, and Carcharias samhammeri Sifting also yielded a plethora of shark vertebrae and I was fortunate enough to come across a beautiful spiral shark coprolite. I found one solitary coral which I assume is Trochocyathus sp. Shark verts, shark coprolite, and Trochocyathus sp. As I scanned the gravel looking to spot a complete Cretalamna, I was instead met with the first mosasaur tooth of the day! It was mostly in tact and showed some nice detail. I was relieved to know the entire trip was already made, and I could spend the rest of my time playing with house money. The only other mosasaur tooth previously in my collection has a beat up crown, so this new specimen certainly complements it. Don't know much about mosasaur genera in the NSR, but I will go with Tylosaurus proriger for now. Throughout the day, we also found tons of very large Enchodus fangs and jaw sections. I'm so used to finding these teeth in their miniature forms as I sift for micros, I almost forgot how big they could get. Lari did good with spotting the Ischyrhiza mira rostral teeth and quickly built up a small collection. She was nice enough to give a large one to me. Top: Fused fish vert and Pachyrhizodus tooth. Bottom: Enchodus jaw section and large fangs. Ischyrhiza mira By now we had hopped a couple of gravel bars and there was still plenty ways to go. It took me longer than it should have, but reaching the third bar finally brought me a large tumbled mosasaur vertebra. Not far from it, there was a section of finer gravel. Used to the routine, I once again got close to the ground and began scanning every pebble. After tossing the millionth shrapnel of shark tooth, I finally locked eyes with the most perfect mosasaur tooth I had ever seen. As I picked it up, I could tell something wasn't right, however. Of course the best side was on full display, but the rest of the tooth was cleaved cleanly off. Oh well, at least it'll look nice in pictures. Not long after, I found a second mosasaur tooth that was decently complete and hooked albeit tiny. Two nicest mosie verts. A slice of an exquisitely preserved mosasaur crown. The next oddball find came awhile later. My initial impression was that it might have been a segment of a Xiphactinus tooth, but the curvature suddenly ended along one of the edges of it. At this sudden end, there were two columns of small protrusions running longitudinally. I was debating on throwing it out, but my history of carelessly tossing neat finds convinced me to play it safe and take it home for identification. I'm glad I did because after the hunt, I immediately googled my hunch and it seems to be correct. This is a fragment of a hybodont spine! I wish I could pin down a more specific ID, but the info on them seems limited. I will say that, out of Moss Creek, I had found a tooth belonging to Lonchidion babulskii last year which could be the culprit. Quite an uncommon find for the NSR! Wondering if any shark experts here might have any ideas @ThePhysicist@Al Dente. Hybodont fin spine. Lonchidion babulskii is a candidate. By the penultimate gravel bar, I thought the best finds had surely been made. All day Lari had been talking about how this was THE spot to find Globidens teeth and how every visit she would find at least one fragment. Well, the walkable land was starting to run out and she expressed how disappointing it would be not to come across one that day. I find Globidens to be really interesting, but I think of it as one of those finds I would never expect to make on any given hunt. For me, not finding one would not define the day as a let down. As I was beginning to form those thoughts into words, I reached down to pick up a circular fragment of a tooth with a peculiar texture. Finding the right angle of light soon revealed the undoubted best find of the day: The top of a Globidens sp. crushing tooth! The whole day I had been hallucinating "finding" Ptychodus teeth. Funnily enough, this may very well be the tooth that ended their supremacy as shell crushers of the WIS. Seems too coincidental that Globidens suddenly appears right around the last occurrence of Ptychodus. I wonder if they directly competed Ptychodus out of existence or if Ptychodus went extinct on its own and mosasaurs simply filled in the niche . I don't think the Globidens of the Ozan Formation has been formally described yet. Globidens sp. Mosasaur teeth of the day! Despite having hunted for over a year in the creeks of Austin, I am surprisingly bad at spotting artifacts. Throughout the span of the day, the both of us had found a few chert flakes, but no sign of anything more even as I was trying to make a conscious effort to spot one. On the same bar as where the Globidens sp. was found, I noticed a worked edge of stone so big even someone as archaeologically blind as me could never miss it. Without an ounce of self control, I yanked it from the sand before I could finish yelling the word "arrowhead"! I seriously need to work on milking the moment . I did a little bit of searching online later and found that the point is likely a Darl or Hoxie. Both put its age in the thousands of years! Darl or Hoxie point. It measures 8.5 cm in length. On the way back, we kept our eyes peeled for anything we may have missed. I was sifting random spots of gravel, but not having the most luck. Lari casually handed me rock with a pearly white exterior and triangular shape. It was the most textbook mastodon I had ever seen, but she wasn't very impressed with it. She told me she had many of these already and that nonmarine fossils didn't interest her. I won't say I understand her terrestrial prejudice, but I will withhold my complaints since it meant I had acquired my first significant chunk of proboscidean . Mastodon enamel, mammoth enamel, and vole tooth. We finally reached Cole at the entrance. In our absence he had wondered off the other way and found a neat spider to pique his entomology interests and pocketed a few fossils. We managed to make it out by the mid afternoon, but I was so exhausted and content, I couldn't bother checking out any other spots along the river. The spoils of the hunt were amazing, but most of all I was happy to finally experience a classic hunt on the NSR as I had seen so many post about before. Doing it with a couple of friends made the adventure even better! Sadly this place has got not much time remaining, so those of you who have stumbled upon this post, maybe take it as a sign to give this historic spot one last go before the opportunity floats away. Thanks for reading!

Hi again! If you saw my thread from yesterday, you'll know I bought some Moroccan fossils for dirt cheap that turned out to be pretty nice. I went to the same dealer today and bought three more for the same price. I suppose I will start with the worst (most suspicious) first: I saw this vertebra and liked how it looked, so I bought it. I'm totally fine with spending $20 for a vert recreation, too, so no big deal if it's fake. What makes me suspicious is the place where it's chipped, it looked like there was paint flaking off. I guess I'm asking, how much of it is real and what is it supposed to be an imitation of? Okay, next is a Globidens tooth and root in matrix. A little beat up, but still cool: Lastly, a weird jaw that I have no clue about. Like I said, I'm not a vertebrate guy. One of the teeth is banged up and looks repaired, but I thought it was cool anyway: Well guys, thanks for looking, I hope you'll find them as interesting as I did! And I said I'd tag @pachy-pleuro-whatnot-odon, maybe you can help.

I found this a while back amidst the red-zone in the Ozan. I'm not sure whether to label it as Globidens sp. or Brachychampsa sp. I'm leaning towards Globidens sp. but would like to know what y'all thought. @JohnJ Apologies in advance about the scale switching back and forth got distracted whilst photographing. Top view (scale in mm): What looks like feeding wear on the (lingual?) side (scale in inches): Feeding wear (within red indicator line) labial? side: Basal: Thanks in advance, - James

Hello, can someone take a look at these and let me know if they are ok? A pair of Mosasaur jaws I quite like. 1st is a Globidens -- from Phosphate Beds. 5.12 inches. Seller says that the tooth is glued, but was found with the jaw. 2nd is Prognathodon -- says it has been glued and has some small fractures filled. Also from Phosphate beds. Many thanks anyone who can help!

While collecting at a location in SE Virginia which produces a mixture of material from the Eocene Nanjemoy Formation and late Miocene/early Pliocene Yorktown Formation, I was shocked to find what I believe to be a cretaceous Globidens sp. anterior tooth fragment. My only explanation for this would be that it must have been redeposited into the Eocene beds and finally exposed with rest of the material. The texture is classic Globidens. The only other species with a slightly similar texture found within these formations (though still markedly different), would be Squalodon sp., however if the tooth were more complete it would clearly prove to be hollow with a conical interior consistent with squamates like mosasaurs. The fragment is approximately 7/8" x 1/2". This is the first bit of possibly cretaceous material I have found from these exposures, so it would be quite interesting if the general consensus is a Globidens sp. Your thoughts would be much appreciated! Thanks, Ash

I've always been fascinated by the Cretaceous sea and its myriad of terrifying carnivores, many that would've made Jaws look meek. After watching BBC's Sea Monsters, I made it my goal to compile a box of sea monster fossils. I started this journey 10 years ago, and finally completed the box recently. Allow me to present my Predators of the Cretaceous Sea collection, and take you on a journey to the most dangerous sea of all times. The box measures 20.25 inches long. Inside are 24 unique predator fossils. I will introduce them from left to right, top to bottom: Rhombodus binkhorsti Age: 70.6 - 66 mya | late Cretaceous Formation: Severn Formation Locality: Bowie, Maryland, USA Size: 1 meters Diet: Molluscs and crustaceans art by Nobu Tamura --------------- Polyptychodon interruptus Age: 105.3 - 94.3 mya | Cretaceous Formation: Stoilensky Quarry stratigraphic unit Locality: Stary-Oskol, Belgorod Oblast, Russia Size: Maybe 7 meters (This is a tooth taxon so size is not confirmed) Diet: Anything it could catch Note: If you consider Polytychodon a nomen dubium, then this is a Pliosauridae indet. art by Mark Witton ----------------- Prognathodon giganteus Age: 70.6 - 66 mya | late Cretaceous Formation: Ouled Abdoun Basin Locality: Khouribga Phosphate Deposits, Morocco Size: 10-14 meters Diet: Everything art by SYSTEM(ZBrushCentral) --------------- Coloborhynchinae indet. Age: 99.7 - 94.3 mya | late Cretaceous Formation: Kem Kem Beds Locality: Southeast Morocco Size: 7 meters (high estimate) Diet: Fish and cephalopods

I managed to get in a few hours before the rain hit at the North Sulphur River Texas. My buddy found a rare Globidens tooth. I found a high quality shark tooth and some coprolite.

A find from earlier this year. Creek bed on the surface here in West KY, (Graves County). Got it because it was different. (I started truly hunting fossils for my son who loves dinosaurs more than anything.) I had no idea as to what it might be but the shape kept me thinking I'd seen it before. I happened to be looking at Mosasaurs one day & happened to see a Moroccan peg-toothed specimen. Researched if they might have lived in the sea here. Saw a paper about Globidens which had some illustrations, then found out about Alabamaensis. Thought I had a jaw fragment minus teeth of one of those. Now I highly doubt it, but you are the people to ask! Who is it, JohnJ who has the quote about convincing yourself to believe anything?

Hi all! I found this in the North Sulphur River this weekend in a large gravel bar. My first thought was that it was a Globidens Mosasaur tooth, but I’m just not sure. It’s approximately a half an inch diameter, has striations on the underside, and a hole in the center. The top side has been flattened, which if a tooth I am assuming is the chewing surface? Completely fossilized. No enamel. I would appreciate any input! Thank you so much!

Hi, What are your opinions on this tooth? Overall the crown of it: Thanks

Hi everyone, With this thread I wanted to start a discussion about what the feeding habits would be for most mosasaur species, how you think they would have fed. I personally love mosasaurs, they are one of my favorite prehistoric animals for a number of reasons and I’ve recently even bought my first Prognathodon jaw and I also live in an area that is not only known for their fossils but also for the discovery of mosasaurs. I’ve been doing a bit of reading lately about mosasaurs but I can’t really find anything difinitive on their feeding habits. Their diet yes. But exactly how they consumed their prey, not yet. I personally work with reptiles on a daily base, both with my job and with my hobby and I know quite a bit of different feeding behaviours with these animals. And as I was feeding the ball pythons (Python regius) at work I was kinda wondering, how would a large marine reptile like a mosasaurus eat? Would they just tear off chunks of meat like their closest living relatives the monitor lizards? Or would they perform deathroll like crocodiles do to tear of chunks of meat of their prey? Or when we talk about smaller prey, would they just swallow them whole like a snake does with it’s two lower jaws that can move independently, would a mosasaur be capable of that? Or would it be a mix of all those things or something entirely different? So I was just wondering what are your thoughts on the subject? I love to hear your theories and own finds and observations or if anyone ever read something in a scientific paper about the matter. I am dying to know your thoughts on the matter, as I want to learn as much as I can about these magnificent beasts!

I bought this tooth from a fossil dealer in Utah 2 years ago. I then somehow after that time noticed a strange mark on the bottom of the tooth where it attaches to the root and that there’s a sand like line going across the middle of the tooth. Could this be repair or fabricated teeth I’m seeing?

GLOBIDENS AEGYPTICUS MOSASAUR TOOTH ON JAW BONE WITH STAND - MOROCCO and a Yeti cup.

Found in north Fort Hood near Gatesville, TX next to the Leon River. Unsure of formation. *would love to know if anyone has that info* Resembles a fish tooth to me, but this one is MUCH larger than any I've ever found (in eastern NC where I live), plus this one seems to have a root attached. It's approximately 3.5cm standing tall, and the "root" is approximately 3cm at its widest point. Quarter is for size reference. I googled some globidens images (as someone suggested) but I have not seen any that precisely match my specimen. For instance, mine does not have any indication of a point or tip. The "enamel" is also completely smooth, and lacks any evidence of striations which were evident in the googled images. It could be, of course, that maybe my specimen is just extremely worn. Any input is much appreciated!

Hi guys, What is your opinion about this tooth? I think it is a real one, no fractures and no covering matrix. But maybe the experts see some red flags.

I bought this partial, very partial, jaw of a mosasaur a few years ago at a very good price. It's from Morocco. No offense to anyone, but I'm always suspect of Moroccan fossils, but it was cheap. This was covered in their famous sand/glue matrix. So tonight i decided to clean it up and do away with most of the sand, and what i found was surprising! See anything wrong with this picture? I uncovered two pits with replacement teeth that were filled with sand. Awesome! BUT they're pointed!! Lol!!! Oh, silly Moroccans. So i popped off a impostor Globidens tooth. Sure enough, it was held on by a white/cream putty. Then i cleaned the putty off of the broken root and globidens tooth. Now, here's my question. Is there a way to determine a species by their replacement teeth? Or does anyone have a good idea which species this may be from the root shape? I'd like to find two correct species teeth to add to this piece to make a composite. I appreicate and thank you for any help. Merry (almost) Christmas.

Hello members I'd quite like a globiden tooth. I have some small pterosurid teeth from Kem Kem to exchange.
