JP3000 Posted May 25, 2019 Share Posted May 25, 2019 Hello clever people, Got these from online. Let me know what you think of them, are they fake? Especially the Spino... Thanks! JP Link to comment Share on other sites More sharing options...
gigantoraptor Posted May 25, 2019 Share Posted May 25, 2019 The three teeth on the left are real, don't know much about Megalodon teeth but seems to be real. From left to right: - Mosasaur tooth from the phosphate mines around Khouribga in Morocco. Many species here so don't know which one it is from this picture alone. - Seems to be Carcharodontosaurid indet., but would like to see more pictures. From the Kem Kem Beds, Cenomanian, Early late Cretaceous. There are two Carcharodontosaurids in the Kem Kem beds, Carcharodontosaurus sacharicus and Sauroniops pachytholus. No way to distinguish their teeth from one another. - Spinosaurid indet. From the Kem Kem Beds, Cenomanian, Early late Cretaceous. There are two Spinosaurids in the Kem Kem beds, Spinosaurus aegyptiacus and Sigilmassasaurus brevicollis. No way to distinguish their teeth from one another. - Carcharias megalodon. No idea about the location. 2 Link to comment Share on other sites More sharing options...

LordTrilobite Posted May 25, 2019 Share Posted May 25, 2019 @gigantoraptor nailed it on the first three teeth. I will add that that first tooth, the Mosasaur, looks like Prognathodon sp. Olof Moleman AKA Lord Trilobite Link to comment Share on other sites More sharing options...

I don't think they "restored" it, given the condition of the labial side. They just polished the heck out of the lingual side probably because there wasn't any enamel left and they wanted some form of shine on it. Sorry, but I am not a fan of polishing fossils like that. 2 Link to comment Share on other sites More sharing options...
Abstraktum Posted May 25, 2019 Share Posted May 25, 2019 Agreed with all what @gigantoraptor said. What I would like to add: - Mosasaur tooth looks very good to me. Nothing wrong with that. - With the Carch tooth I'm having the most trouble. It seems to be there is a lot of glued Matrix on it. Always a very bad sign. You can take a look at this topic where I rebulid a fabricated Carch tooth. Unforunatly I think your tooth might has a similar issue. - Spino looks really nice. Can't see any obvious problems. - Mega tooth looks weird. On the first picture it looks VERY polished. Sort of like a mirror. But I'm not that much into Meg teeth. Maybe some of our Meg experts can have a better opinion on the Meg tooth. 1 Link to comment Share on other sites More sharing options...
Brett Breakin' Rocks Posted May 25, 2019 Share Posted May 25, 2019 The meg tooth is 100% real and heavily polished .. a common and unfortunate way to bring back their former glory. The good sellers will indicate when they have been altered/polished for the buyer. Cheers, Brett 2 Link to comment Share on other sites More sharing options...

Starting with course grits, sanding down with finer and finer grits until smooth. Then use a polishing compound to give it the final shine. Similar to polishing a stone cabochon for jewelry. You can see on your Meg. tooth that they polished beyond the enamel area into the burlette and root. 2 Link to comment Share on other sites More sharing options...

PODIGGER Posted May 28, 2019 Share Posted May 28, 2019 Thanks to all for the input and suggestions. I'll just shave the ice and add tequila to the jello when finished with the sanding and polishing! Link to comment Share on other sites More sharing options...

minnbuckeye Posted February 5, 2020 Share Posted February 5, 2020 Too bad. I would never feel comfortable buying teeth for fear of this. Link to comment Share on other sites More sharing options...
Troodon Posted February 5, 2020 Share Posted February 5, 2020 This is an issue primarily with Moroccan teeth, why you need to be very cautious and not buy one unless its a slam dunk that is clearly good. Rooted teeth are much more apted to be tampered with. I buy all my Moroccan teeth at shows so they can be inspected. The alternative is buy only from online sellers that accept a return with a full cash refund. I was traveling and did not see the orginal post but like Abstraktum said the resto/repair were pretty evident on that tooth. Link to comment Share on other sites More sharing options...
Pemphix Posted February 5, 2020 Share Posted February 5, 2020 Troodon showed some of the polished Megs on his pictures from Tuscon Show. Polishing seems to be a common way for some dealers, unfortunately.... Link to comment Share on other sites More sharing options...
JP3000 Posted February 5, 2020 Author Share Posted February 5, 2020 I wonder if the acheulean hand axes for sale can also be dodgy? One would guess they are much easier to fake... nyone knows about it? Link to comment Share on other sites More sharing options...
Troodon Posted February 5, 2020 Share Posted February 5, 2020 Artifact especially points are commonly faked. You need experts to verify they are real. Link to comment Share on other sites More sharing options...
Haravex Posted February 6, 2020 Share Posted February 6, 2020 Spinosauridae tooth is real and the mosasaur looks good too (also too common to be worth trying to fake a crown roots are different I believe) but I'm not very knowledgeable outside of kem kem and el mers group fossils of morocco, as for the carcharadontosaurid tooth it looks to be a fragment of the mesial side and then built up using sand glue other pieces. There are a lot of fragmented pieces in the kem kem these normally get sold or picked up by certain people to go to what is best to call factories from home to be made into something of value.
