Hello friends! I found this piece of Prognathodon anceps jaw for sale. Do you think is real? I appreciate your comments! Thanks
-
So recently my father bought a 3D printer and we've been experimenting printing some cool fossils for a while now. It's a really cool technology. Though it can take a while to print a piece the results are really quite cool. A life size Archaeopteryx can take a few days to print if you don't keep printing during the night. Finishing up the prints afterwards can also take a bit of time. Cleaning off all the supports and sanding down rough surfaces can be quite the process. Then there's painting depending on the desired result of course. There are actually a lot of nice things that can be found for download on the internet. Though many of these models still require a bit of digital cleanup before they could be printed. So here are a number of the painted, unpainted and half painted results. Most of the printed stuff is dinosaur. Photo of the 3D printer and the just finished print of a juvenile Edmontosaurus lower jaw. And here's the same Edmontosaurus jaw print half painted again with the real fossil in mirror image next to it. I scanned the original bone that I then mirrored digitaly so that I could print out the other side of the jaw. Allosaurus hand claw. Clidastes Mosasaur quadrate bone. Skull of the "Prosauropod" Massospondylus. Holotype right lower jaw of Owenodon hoggi, an Iguanodontid.

Is this Mosasaurus tooth and it's root real?
sharpteeth posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hi everyone! I recently bought this Mosasaur tooth with a complete root attached. It was found in Morocco. I know there are many fakes around where they glue a real crown to a fake root. I hope you guys can tell me more on it and possibly verify it's authenticity. (Size: 14cm in length) Thanks in advance!

Can someone explain to me the differences in Morrocon Mosasaur naming?
sharpteeth posted a topic in Questions & Answers
Hi everyone! Can someone help me with the naming of Moroccon Mosasaurs? I recently aquired a Mosasaur tooth (with root). And the person who dug it up said it belonged to a Prognathodon L. anceps Owen. I did some reading and I found there has been alot of discussion about the name and it has changed over the years. I am confused now. So what I understand is that due to lack of scientific observation of the fossils in Morocco, the P. anceps is not officially assigned to a specific family of mosasaurs. Correct me if I am wrong? But what is the most up to date name for the P. anceps? Is it: - Prognathodon anceps - Prognathodon anceps L. Owen - Prognathodon Liodon - Prognathodon Leiodon - Prognathodon.sp - Prognathodon sp. (What does 'sp' stand for?) I am making a display stand for my tooth and I want to put a nameplate on it with the correct name. Thanks alot in advance! P.S. See pictures below for the tooth in question.

It was a slow day at the North Sulphur River. With no rain I wasn't surprised the river was really picked over. I did find one medium sized shark or fish vert. I also found something that I have no idea what it is. Fossil, geological, or man made? Anyone have any idea what is in pictures 3, 4, and 5? 1. 2. 3. 4. 5.

North Carolina Ammonites, Mosasaurs, Sharks, and More!
fossil_lover_2277 posted a topic in Fossil Hunting Trips
I recently went on two fossil hunting trips to Cretaceous sediments of Eastern North Carolina, the second of which was earlier today. Today’s trip to the Bladen formation yielded baculites ammonites, some worn mosasaur teeth, the nicest goblin shark teeth I’ve personally collected, some fish mouth plates, turtle shell fragments, and some other goodies. My first trip a couple weeks ago was to Tar Heel formation sediments and I collected several small mosasaur teeth, a mosasaur vertebra, a piece of petrified lignite, lots of goblin and crow shark teeth, lots of turtle shell, a very worn Deinosuchus tooth, and some coprolites (I’ve posted a few of the images from this trip in the ID section of the forum already). North Carolina is an amazing U.S. state for fossils, it has loads of fossils from the Paleozoic, Mesozoic, and Cenozoic (although if you want Jurassic look elsewhere). If you haven’t already, you should come check it out! Pics from today’s trip: Pics from the first trip:

Mosasaur skull...real or a fabrication??
fossil_lover_2277 posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hi all, I saw this mosasaur skull online for sale, curious...is it the real deal, or a fake? It’s from Morocco. I think it’s real best as I can tell, but I’m sure there are some good fakes out there, and I don’t know how to tell for sure without using a microscope...really need some help on this one. **update: I bid on it and won, so I hope it’s real..pretty sure it is..

I found this tooth in Greens Mill Run in Greenville, NC. I’m leaning towards croc due to the size of the dental cavity relative to the size of the tooth, but perhaps it is a mosasaur. It has one carina on the anterior side of the tooth, none on the posterior side. Also, if it is croc, is there a way to identify whether it’s Cretaceous or Pliocene? Or if either croc or mosasaur, perhaps genus ID? Thanks!!!

Hi all! So I recently posted regarding a bone ID on a mystery mosasaur/dinosaur vertebra (I’m leaning towards it being a mosasaur vert.). The vert. came out of either the Cretaceous Bladen or Tar Heel formations of North Carolina from a marine site that yields dinosaurs, crocs, mosasaurs, turtles, and fish (including sharks). Well, I went back through the material I had collected (from the same site as the vert.) and found what I believe are a worn tooth and a fragment of what I believe to be the proximal end of a femur (although I could very well be wrong on that). The tooth I would have thought to be croc or mosasaur, but it is not conical (it’s more “chisel”-like), and I haven’t seen anything quite like it. The “femur”, as far as I can tell from looking up images...appears to be dinosaurian, but I’m not sure. Any help would be greatly appreciated as my knowledge of zoological anatomy is limited **Update: I checked the “femur” under a microscope, I don’t see any bone histology, I think it’s just a concretion of some sort. Wasn’t sure because so many of the bones from this site are worn down. But of course the tooth is definitely a tooth. No idea on the ID still.

Mosasaur skull - Broken, fragile, in need of advice...
Scribbler posted a topic in Fossil Preparation
Hello TFF members - I'm in need so some advice on this one please. So this is my first post (happy to be corrected on any newbie errors) and although preparation is my favourite part of the fossil game, I am 'fairly' new to it - In other words, please go easy on me, I'm aware it's going to be all too tempting to say I've bitten off more than I can chew here... I recently purchased this Mosasaur skull from a well known European fossil auction site; you may have seen it yourself if you follow such things. It wasn't 'hugely' expensive, but that doesn't mean I'm not serious about making something good out of it and giving it a lot of attention (which clearly it will need...). It is from Morocco, was sold as a Platycarpus (from the teeth I would tend to agree, but please correct if you think otherwise) and originally was complete in a plaster jacket. The seller decided to prep it and remove from the jacket. Whilst this may have exposed more of it, some quite nicely, they have also turned it into the most insanely fragile fossil I have ever come into contact with! It was already in five large pieces when advertised for sale, and despite being very well packaged, has suffered further in transit. The matrix is not much more than hard (ish) sand and the bone only marginally more solid. Doesn't help that it's so crushed, so only matrix between each piece. Clearly leaving it in the matrix, perhaps replacing the jacket with something more aesthetically pleasing as part of a mount and prepping only the surface would have been the way to go, but it's beyond that now, so I would really love some thoughts and suggestions on the following: 1 - Immediate stabilisation and strengthening to prevent further breakages and reattach the broken sections (buckets of CA to solidify the sand matrix and reduce porosity to enable gluing?) 2 - Rebuilding/mounting (combining these two, as it will never be strong enough to hold in one piece and the mounting technique will likely need to be integral as it will need complete support across the entire back. It would never be my first choice, but I'm thinking a rebuilt matrix under the fossil to support and hold it together at the same time?) Ok, lots of text there for background and to give you more context, here are some pictures which will help... Original, in jacket: Advert pics: And another: Now it's home, in a slightly more confused state: And another: Last one, you get the idea: If anyone is interested in seeing more of it, please let me know, have lots of pics. It's an interesting item and despite being crushed to hell, looks to be fairly complete (the reverse tells it's own story too, more teeth there, etc.), but it's realistically only ever going to be an 'in matrix' display piece. Out of curiosity, I believe it's upside down, with the two maxilla visible on top and the upper jaw section being below, sure someone will easily be able to confirm? Anyway, enough from me, would love your thoughts and really appreciate anyone who has the time to consider and reply. If I haven't been clear or you need more info, please just let me know. Thank you, Dave

I acquired this fascinating fossil at the recent show. My first reptile bones. The dealer said it is from Morocco and of the same age (and matrix) as the mosasaur jaw sets he had next to it. But he wasn’t sure if it was a baby mosasaur or a different species of smaller aquatic reptile. I’m pretty sure TFF can answer these questions I have. 1) Is this a baby mosasaur or a different species (if so what species)? 2) Can you identify the visible bones? 3) Is it worth it or feasible to attempt to reveal more of this fossil? 4) If so, what special procedures/tools would be necessary to prep this fossil to reveal more skull?

I went out to brave the Texas summer heat and was well rewarded. Post Oak Creek is so heavily picked, especially in the summer, that I didn't expect much. I even went there with the Dallas Paleontological Society last month and saw a ton of footprints then and not many good teeth. The first three hours I found almost nothing, as I expected the surface was all picked over, however I found one gravel bar that people must not have gotten to because I started finding a few decent cretodus, squalicorax, goblin shark teeth, and a couple of nice ptychodus. Finally I found two huge teeth about a foot apart from each other. The first one is by far my largest ever complete tooth that was as large as two quarters. Then the next one with the nice cusplets is larger than a quarter which would still have been my largest find if I hadn't of found the first one. There are also two pictures, front and back, of some worn chunkosaur bones and two micro teeth. Also another cool find was a ptychodus in the secondary matrix. See if you can spot it? I always like to look in the secondary matrix sticking out of the river banks as I usually find a small tooth or two but this time I found a good one. The last two pictures are of a worn vertebrae. Not sure what from though. Mosasaur?

North Carolina Dinosaur or Mosasaur Vertebra or phalanges?
fossil_lover_2277 posted a topic in Fossil ID
Hi, I recently found a bone that looks like either a vertebra or a phalanges. The bone is from eastern North Carolina, legally collected from public land, and comes out of either the Cretaceous Tar Heel or Bladen formations. Both marine and freshwater organisms as well as dinosaurs are known to be found from the general area. The bone does not look like it comes from a turtle or crocodile, but I could be wrong. Is it a dinosaur or mosasaur bone, or something else? And no, there is no way this bone is Cenozoic. Thanks!

To mark the occasion of this new sub forum for museums. I would like you show you some wonderful stuff in Teylers Museum in Haarlem, Netherlands. This is actually the oldest museum in the Netherlands and thus also has some really cool history attached to it and it's specimens. http://www.teylersmuseum.nl/en Besides fossils this museum also holds an art and science collection. The museum is just as beautiful as the specimens in it and a true time capsule. While it is quite a small museum, it's charm is worth the trip alone. Even the cabinets are pretty. It even has a few world firsts, such as Archaeopteryx and Mosasaurus. Now on to fossils! One of the most important specimens on display here is one of the Archaeopteryx specimens. This is actually the first Archaeopteryx as it was found before the feather and the London specimen were found. But for a long time it was labeled as a Pterodactylus. Only later was it found that it was in fact an Archaeopteryx. While very incomplete it is one of the larger animals of the genus (the third largest I think). the specimen consists of slab and counter slab. If you look close you can still see the vague impression of the flight feathers on the wings. It also very nicely shows the keratinous sheaths of the claws. Archaeopteryx lithographica Along with Archaeopteryx Teylers also has a very nice collection of the Jurassic of Solnhofen in Bavaria. They have a number of Rhamphorhynchus skeletons, lizards, fish, crustaceans and squids complete with tentacles and inksacs. Rhamphorhynchus Various fish Homocosaurus maximiliani Various critters

Found this yesterday in the Ramenessin Brook in NJ. I'm thinking it could be a mosasaur tooth. Would appreciate your feedback. Thanks!

Hey all This has popped up on on my country's version of online.... yep, no online here! I appreciate your thoughts on this one I'm sceptical... real tooth, seemingly in good condition (on the one side at least) apart from a missing tip. I can see two different colours on the matrix.... is the bulk of it real matrix with fake matrix coated over the top to hide a bunch of inconsistencies? Or is the whole lot fake matrix. The area where the crown and root meet is bad, really bad - definitely manufactured. Is that even a real root or a random piece of bone? Assuming the root is genuine, I'm guessing there is no way to tell if it is associated with that tooth? I have a very off feeling with this but as always, I'll let the experts pick it over. I've posted all the pictures that are listed with the auction The description is poor.... no further info is provided. Really great specimen of a mosasaur tooth. Hard to find with the root still attached to the tooth. Would make a great addition to any fossil collection. I only deal in unique, rare and high quality pieces of fossils and gemstones. 120mm x 95mm x 38mm

Several Moroccan mosausaur teeth I’d appreciate an ID for. I don’t know how to identify mosasaur teeth. Better pictures might be required so would be more than happy to send them if needed.

Found these teeth in Big Brook,NJ today. First one I’m sure is a mosasaur but I’ve no idea on the second one. Thanks.

Hi everybody, I've seen this mosasaur skull... it has been classified like Eremiasaurus heterodontus from morocco . 750 x 380 mm. What do you think? Thanks

Hi everyone, I currently have a friend in Morocco who recently found two teeth which he believes are the front dentary teeth of Carinodens which by itself are extremely rare but this tooth position especially. After doing some research I agree with my friend in Morocco about the ID to which he came to. But due to their rarity they are pretty pricey and because of that I wanted to have a second opinion just to be sure. Thank you all in advance! @jnoun11 @pachy-pleuro-whatnot-odon Care to chime in?

Hi, I just saw these articles, and I wanted to make sure they are real. The vertebrae of Onchosaurus seem correct, but I am concerned about Otodus' teeth, and that of Mosasaur. Mosasaur 2.2 ctms.(Just the tooth ). and Otodus 5 ctms.

Hey all, Feeling a little like the boy who cried Mosasaur. I am fairly confident what I have here is a Mosasaur but wanted to get another opinion. The species I believe to be Proghathodon rapax (Hay).
