I'm considering purchasing this platecarpus jaw. The only thing is......I'm not sure its platecarpus at all. It certainly looks mosasaur to me, but something about the spacing between the teeth seems off.....maybe halisaurus? The jaw is 8.66 inches long, it's from morocco (ouled abdoun basin), and it's currently labeled as platecarpus ptychodon. any help would be greatly appreciated!

Ive been trying to ID this fish jaw but I'm a newbie so I can only go so far before I need guidance! Any ideas on what this may be from?

So I have not posted in quite some time as I mostly do the Facebook updates because it is so easy to deal with the photos, but I thought I should get this one in now that I think it is over. I went on a hunt around the middle of January that turned out pretty well. I had walked a good ways and had found nothing which can quickly put me in a bad funk, but I finally came across a mosasaur vert encrusted in matrix, so my disposition changed a little. Always nice to find something to get rid of the skunk (sorry, fishing term). Not too far from the exit point, I just happened to glance across and my eye settled directly on a mosasaur tooth socket. I knew exactly what it was when I spotted it from over 15 feet away. I went straight away to collect what was a small section of jaw with a couple of broken off teeth (pretty typical of the NSR). When I reached down to pick it up, I realized that there was another piece of the jaw and that it would connect with the piece I was retrieving. Score! Now a nice 6 or 8 inches of jaw would look better all glued up, but then I gained a little more focus and realized that what I thought were rocks, were the edges of more bones, and more important was that the fact that the other bones were in the shale and not sitting on top! I gathered myself and beat away the excitement as I knew that I had just found the resting place of a mosasaur. It was getting dark and there was rain in the forecast, so I figured that I would pull out the few pieces that would get washed away. When I went for the first vert, I had totally missed that there was a visible tooth half way in the matrix. I scratched a couple of times near there and that is when it hit me! That jaw bone was going into the ground and there should be more of it! I have a long story about a hike out as I was not prepared for such that I will spare you from, but I had finally found some jaws with teeth whether I would destroy them getting out of there or not. There is more to this story, but I wanted to at least share what got me so excited and the reason I spend hours wandering around in the middle of nowhere.

I found this mosasaur paddle bone on the auction site. Thought it might be a cool piece. But it is from morocco, and I've heard about the huge amount of mosasaur fakes from there. So is this real???
-
So I found this skull and I'd love to maybe get something like this in the future, I could possibly do prep work to make it look better. But is it real? I can't tell. All I know about it is it's from morocco.

This past weekend was the 50th annual Rutgers Geology Museum open house, which was an excellent opportunity to attend guest lectures by professionals and also a chance see the museum's collection. The event was very well attended, and in between lectures (the lecture by Dr. Isaiah Nengo on his work with Nyanzapithecus alesi was excellent) seeing the museum was a hurried, crowded affair. The museum building is a tall 19th century structure with many large tall windows, so on this sunny Saturday sun glare on the glass cases was unfortunately a real and unavoidable problem. Nevertheless, I made an effort to get some photos of the museum to share with TFF. The Mastodon is a Salem County NJ find. Particularly exciting for me as a huge fan of Phytosaurs was seeing their specimen of Rutiodon manhattenensis, which despite its specific name was found on the New Jersey side of the Hudson. Yet another example of New York stealing New Jersey's credit! Hidden in a corner (it was packed in there, things crammed into corners to make room for tables) was a skull of Mosasaurus "maxmimus" which I'd have loved to known more about since it was apparently a New Jersey find. Alas, no more info than that. Next to it was a cast of the original find Mosasaurus hoffmanii from the Netherlands, which was neat to see in real scale.

Hi guys I felt well enough to take some quick snaps of one of my fossils, I am sorry the quality isnt amazing but I still aint over my flu yet. I think this is a tooth from a Mosasaur, but thats going from what has been posted on this forum when I have been reading through all the old posts, I will have to make a few posts to fit a few of the pictures on and will make them smaller next time so I dont have this problem. I bought this from friend decades ago, he thought it might be a Mosasaur Bogey or something like that, no idea where it came from at all.

I was able to attend the Tucson show over the weekend, and as always, found some goodies I could afford. Both of these are from Morocco, and both are still quite a mess, unfortunately. The partial skull has had some filling on the teeth, but I know that's usually the standard procedure before selling, and I understand that. I'd love to have both of them prepared and have an identification tag for them if possible. I know they can be notoriously difficult to identify at times, but I thought it'd be worth a try!

Tylosaurus proriger Found in the North Sulphur River, Ozan Formation Dated Campanian Stage of Cretaceous (≈80 mya) Measures 4.4 cm (1.7 inches) -
Found this tooth in GMR in eastern North Carolina today. Some have suggested a mosasaur tooth or a gator tooth. The back is missing, but there is still a curve on the tooth. Thanks for looking. We also found belemnites upstream from here.

Red flag on Mosasaur skulls
Aurelius posted a topic in Is It Real? How to Recognize Fossil Fabrications
Just a quick note to be careful when buying Mosasaur skulls. I know that this particular specimen may look incredibly convincing, but read on. This is clearly one of the most impressive skulls ever to have come onto the market. Indeed, the seller believes it to be worth $6,500 and describes it as 'museum quality'. I immediately recognised that this must be a new species. A careful, scientific examination of the photographs revealed that this animal had incredibly wide eyes, and a bone structure entirely unknown to science. Obviously this is a very rare find, and I immediately took steps to remortgage my home to secure the purchase of this remarkable animal. However, I had gotten as far as drawing a life-restoration of this creature (below) to include with my scientific paper describing this new specimen, when I began to have my doubts. Artist's reconstruction Firstly, the fact that the skull was clearly cobbled together from lumps of modern bone, sand and glue began to ring alarm bells with me. I am very astute, and my trained senses told me that an animal would be unlikely to evolve in such a way. Secondly, the fact that the surfaces were all flat and appeared to be almost two-dimensional, and that the whole thing was clearly rubbish, clued me in that all was not as it seemed. I'm thankful that my superior fossil know-how prevented me from buying a dud. On the plus side, the verts look like they might be real marine reptile, as are the crowns of course, which makes the $200 starting bid a bit easier to swallow..thumb.jpg.f14c50a8c5d3791a3c3882f0e26d2d34.jpg)

From the album: My Fossils
I found this tooth from Morocco I’m a shop in Portugal. While the root could be faked in someway. The actual tooth, is real. I did a post on this before but I took much clearer images for the ID for this later on. I decided to repost with these images. -
Prognathodon (Mosasaur) tooth from Morocco
Kaiju Slayer333 posted a gallery image in Member Collections
I found this fossil in Portugal in a little shop. The tooth was from Morocco and is likely a Prognathodon. While the root has been said by others to be likely fake, the crown (the main point of the fossil) is likely real. -

From a creek in NC that has Cretaceous fossils. Could it be a very worn mosasaur tooth?

I was reading a description of Mosasaur material that made me re-think a vertabrae I considered to be Mosasaur. It is from Monmouth County NJ (Cretaceous) and does have a cone shape so I was wondering what exactly it is. On njfossils.net it gave this description (below) of Halisaurs so I was wondering if it could be this or even croc. Any help is appreciated. -Frank "The rare species, Halisaurus, has vertebrae that are distinguishable by the conical shape of the vertebrae. The main difference is that they are tapered toward the convexed end of the centrum and lack the divot of "crocodile" vertebrae."

My name is Gary L Thompson I am the sole discover of the Mosasaur Prognathadon stadtmani that currently resides at BYU, This specimen was found in Cedaredge, Colorado in 1975. It took over 40 years to get the complete casting of this mosasaur. I thought maybe this might be a story of interest for you since this is an extremely rare fossilized specimen from about 85 million years ago and the fossilized marine reptile is the only one ever found on the western side of the prehistoric sea that once covered an area ranging from Utah to Kansas and Nebraska. It was a ferocious creature approximately 35 feet long. The excavated skull bones remain the property of Brigham Young University’s Paleontology Museum." I just wanted update every one on some misleading information regarding the find and to send the most current information updates. It appears that the Genus name is probably going to change to a brand new Genus, the scientific community is still discussing this one, will try to update when that happens. BYU has now completed the entire skeleton and now have it up as of the beginning of the year. I have included current photos of it along with "My true story" and all corresponding credits for the find, scientific research and preparation of the specimen. I just thought these might be of interest to you. The photos are from the BYU webpage. My true story finding a mosasaur.docx Order of Contact and Credits.docx Original_article_1975.docx

After working 28 thirteen hour days offshore I couldn't wait any longer to hunt so I headed to my favorite Northeast Texas creek. The temp when I left was 20 degrees which is really cold for my area. The creek was frozen but I had still had some area to hunt. I walked for miles and didn't find much then ended up finding everything around the bridge where I parked lol. I found more artifacts than fossils but did manage to find a Mosasaur vert & Mastodon tooth enamel.

Hi, Assuming this is a mosasaur tooth. I found it on the North Sulphur River. I haven’t seen a mos tooth with such a wicked curve so it had me wondering if it might belong to something else. Thanks!

Happy New Year y’all, Squeezed in a few days on the Sulphur over the last week. Went to a few of my favorite spots and checked out a new spot. All areas are fully accessible after the last few rises in water level. The gravel looks great due to the few light rains we’ve had since the big rains. Things seem to be back to normal out there as far as the amount of fossils to be found. I had a real hard time finding anything of significance after the last big 30+ft rise. Luckily things are looking a lot better now.

Platecarpus ptychodon jaw
Fossil'n'Roll posted a topic in Is It Real? How to Recognize Fossil Fabrications
I found this yesterday listed as a 10.7" Platecarpus ptychodon jaw section. Everything looks fine to me, but I want to be sure it's 100% real and not composited before deciding whether or not to buy it. The price seems surprisingly low for a jaw section of this size.

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.

@KimTexan asked to see some of my jaw sections so here's a few from the North Sulphur River Texas. This is a nice mix of Xiphactinus and at least 2 species of Mosasaur.

Here's a sample of my favorite teeth and artifacts. Most are personal finds from the Northeast Texas area.
