  1. Is this a real jaw? Any red flags?
  2. As the title says.. Just saw this for 400 on our favorite auction site as 100% authentic. One can clearly see its plaster and you can see the work marks..
  3. I had a great day the North Sulphur River. I found my first red mosasaur tooth and 2 Native American Drills which are very rare to find in that are. Numerous other shark teeth, mosasaur verts and a cool old cork style bottle in the pic.
  4. Hi folks Are all mossy verts concave one side and convex t'other? All the images I've found aren't clear enough. @JarrodB @doushantuo @LordTrilobite
  5. Hello there paleontologists, fossil enthusiast, and everything in between. If you couldn't tell this is the first content I've ever made on the fossil forum so please excuse errors and, or inexperience I apologize in advance. Here is my collection of display fossils as well as modern bones keep in mind this is purely what I have on display I keep the vast majority of fossils I posses in storage with lots of support such as bubble rap and various other materials to ensure complete security of precious peeks into our planet's history. If you have any questions or comments feel free to ask as you please. These are all authentic fossils 2 have been directly seen by a professional (Ursus sp. & Unidentified Dinosaur Cretaceous Rib) The Dactylioceras sp. is very clearly a real specimen however there was no authority on it's authenticity the two Hadrosaur fragments are authentic as well one purchased with it's card of authenticity by D.J Parsons and the other was purchased from the very same hunter whom discovered the Cretaceous rib section. (Note: individual specimen content will be released in time)
  6. So the other day I visited a local tiny shop that sells minerals and fossils, and snagged a Mosasaur tooth from Khouribga Morocco. The label only said 'Mosasaur tooth, Khouribga, Morocco.' Naturally, as the curious person that I am, Im trying to find the species of the owner. After I researched a bit I narrowed down the species to those found in Morocco, yet I had trouble finding one with similar teeth. Globidens and Carinodens were quickly out of the question, since the teeth are rounded and kinda look like mushrooms to some extent, very unlike mine. Yet practically all the teeth I saw for these other Morocco Mosasaurs had slightly hooked teeth that looked thick and heavy, While mine is practically vertical, with almost no curve to it, small and light. Anyone know any Mosasaur species with teeth like this found in Khouribga Morocco..? The measurement of the tooth without the root is 1.4 inches long. The tooth has a diameter around barely over 1 centimeter. Here are species found in Morocco that I had narrowed down to, minus the Globidens and the Carinodens included- Eremiasaurus, Prognathodon-Anceps, Solyvai, Curii, Mosasaurus Baugei, Tethysaurus, Platecarpus, Halisaurus, and Goronyosaurus. ~If you need another angle of the tooth feel free to ask~
  7. Explored another new North Texas creek. Not many fossils but great for artifacts. We did manage to find one beat up Mosasaur vert, shark teeth and a Gastropod. 10 hour hike. :/
  8. Hot North Sulphur River hunt. I followed some footprints but still managed a nice variety.
  9. From the album In-Situ Shots(various locations)

  11. hy mosasaurs lovers i looked around on differents americans fossils web sites , and i found ,is nowhere a description or list about different species of mosasaurs from morocco . so I'll try humbly to fix it . feel free to correct me if you see something wrong. the moroccan phosphate history began in 1921 , Moroccan phosphate mines operate three layers of phosphates ,. level 1 : ypresian phosphate bed level 2 : thanetian phosphate bed level 3 ; maestrichian phosphate bed level 4 ; maestrichian grey phosphate only at sidi-chenan quarry of courses , mosasaurs belong to the level 3.and 4 different species are studied by scientists of the French Museum of Natural History in Paris . today the last record of different mosasaurs species is at list 17 and probably 20. (personal opinion ) listed like below : †Halisaurus. arambourgi .(Bardet, Pereda Suberbiola, Iarochène, Bouya & Amaghzaz, 2005) †Halisaurus.sp not described yet †Halisaurus walkeri .(Lingham-Solier, 1998) ( i used this name temporarily, until one studie about this mosasaur show-up ) †Prognathodon sp Dollo, 1889 †Prognathodon anceps ex leiodon anceps slender form massive form perhaps sexual dimorphism ( personal opinion ) †Prognathodon solvay Dollo, 1889 †prognathodon hudae kaddumi 2009 †Prognathodon. currii (Christiansen & Bonde, 2002) †Eremiasaurus heterodontus , gen. et sp. nov sp ( AR. H. LeBlanc, M. W. Caldwell, and N. Bardet. 2012) †“Mosasaurus" baugei Arambourg 1954 ( Mosasaurus beaugei Arambourg, 1952 (Squamata, Mosasauridae) from the Late Cretaceous phosphates of Morocco Nathalie Bardet , Xabier Pereda Suberbiola , Mohamed Iarochene , Fatima Bouyahyaoui , Baadi Bouya , Mbarek Amaghzaz . 2004 ) †Mosasaurus hoffmanni Mantell, 1829 †Tylosaurus Marsh, 1872 slender form like tylosaurus proriger massive form like hainosaurus personal constatation †Platecarpus ptychodon Arambourg 1954 †Globidens. phosphaticus (Bardet, Pereda Suberbiola, Iarochène, Amalik & Bouya, 2005) †carinodens belgicus ( N. Bardet, X. Pereda Suberbiola, M. Iarochène, M. Amalik, and B. Bouya. 2005) †carinodens minalmamar. (A.S. Schulp, N. Bardet& B. Bouya. 2009) †harranasaurus khuludae. (kaddumi.2009)
  12. The seller of this piece claims that the teeth are not composited onto the matrix, but, judging by this picture, I would say the roots aren't original. They lack texture and the one on the left in the close-up seems 'smudged' up onto the bone. I would imagine the block has original bone but most of the teeth added afterwards, but I may of course be wrong. Can someone more experienced please give their opinion? Either way, it looks like a great piece to me, if a bit out of my price range! Many thanks.
  13. I went for a dig last weekend and wanted to show what I came up with. It was a great day for a dig, the weather has been perfect for them lately. My last few trips were nothing special but today my sifter was treating me very well! I came up with three Mosasaur teeth and this ratfish jaw chunk. I have never even found two nice Mosasaur teeth on a single trip so this was a really good hunt for me. Cheers! -Frank
  14. Last week I donated this mosasaur jaw section to the team at SMU in Dallas. They are working on a comprehensive study on the local Mosasaurs in DFW. They were interested in the replacement tooth. Always feels good to give back and I encourage everyone to do so if possible.
  15. Dear fossil preparation experts, I recently acquired a series of articulated vertebrae of a Mosasaur in it's original matrix. The fossil is coming from Kem Kem region in Morocco. My goal is not to extract the fossil bone from the matrix. This would be quite difficult due to the fragility of the specimen. Instead, I would like to clean up the matrix to make it look nicer. Now, my problem is the following: In some areas the matrix is quite dense and hard. In some other areas it is extremely brittle (almost like sand). I would like to use this original matrix-sand to repair the matrix in some spots. I was thinking about mixing the sand with liquid (water? glue?) to get a material that I can use for re-modelling the damaged matrix. Does someone have a good recipe for that? Thank you.
  16. From the album Platecarpus start to finish

  17. Mosasaur teeth and Otodus tooth from Morocco for trade. I like all different kinds of fossils so I'm not going to specify what I would take in trade.
  18. A friend of mine proposed to buy this piece. What do you think? thanks to everybody
  19. I rarely sell fossils but my friend in New Zealand told me how much his son loves Mosasaurs so I figured I could afford to let one Mosasaur tooth go. I threw in a variety of NSR / Post Oak Creek shark teeth, small ammonite and a few Mosasaur verts as a bonus. He sent me this pic today of how happy his son was to get the package of fossils. I think he has a fossil fan for life now.
  20. Can anyone tell me if this is a mosisaur tooth or if not what time of tooth it is it was found in the smokey hill chalk of Kansas
  21. I found these jaw pieces with tooth stubs in them ,I can't tell what they are from (I think mosasaur)
  22. I have stumbled upon a mosasaur skeleton (or at least I assume so ) it is in pieces and I have so far found 3 ribs and 3 vertebrae and it keeps going back into the chalk that it is in . It is in the Smokey Hill Chalk formations in Kansas. It is in many pieces each rib is in about 5-12 pieces and vertebrae are mostly intact
  23. Hello! I found this fossil probably 20 years ago in the Sulfur River near Ladonia, TX. I was told at the time that it is Cretaceous in age and likely from a Mosasaur. Is this a Mosasaur fossil? And if so, what body part of the Mosasaur is it from? It looks like a joint to me. It is about 6" wide, about 4.5" tall, and is convex on the "bottom".
  24. Long hike at NSR. I did manage to find my first turtle vert and Stratodus palatine bone. I love the colors on the little Mosasaur tail vert. It was a beautiful day and animals were on the move. More pics.
  25. A partial left dentary (lower jaw) of a small mosasaur. On the side there is a large pathology visible on the bone surface.
