Seguidora-de-Isis Posted September 10, 2017 Share Posted September 10, 2017 I have some doubts about this lot of Moroccan of teeth fossils. All opinions are welcome, and I thank you! Fossil Nº. 01 - Peyeria lybica fossil teeth (kem kem) It's real? I do not know if it has already been described scientifically ... How should I label this in my collection? ============================================================ Fossil Nº. 02 - Ceratodus fossil teeth (kem kem) It's real? I do not know if it has already been described scientifically ... How should I label this in my collection? ============================================================ Fossil Nº. 03 - Pterosaur Coloborhynchus fossil teeth (kem kem) It's real? Is It real, or it's not real, that's the question! Link to comment Share on other sites More sharing options...
Fruitbat Posted September 10, 2017 Share Posted September 10, 2017 For some reason...fossil number one looks more like a bivalve shell than it does any kind of tooth I've ever seen. Number two definitely looks like a lungfish (Ceratodus or related genus) to me...and the size is not outlandish. They are relatively common in the Kem Kem area so I don't know why anybody would take the time to fake one. I'm afraid that I can't help you with number 3. -Joe 2 Illigitimati non carborundum Fruitbat's PDF Library Link to comment Share on other sites More sharing options...
Al Dente Posted September 10, 2017 Share Posted September 10, 2017 The Peyeria looks nice. At one time they were thought to be rostral teeth of a sawfish but now are thought to be dermal denticles. 1 Link to comment Share on other sites More sharing options...
Fruitbat Posted September 10, 2017 Share Posted September 10, 2017 Well I've learned something new once again! To be honest, I'd never heard of Peyeria before but that certainly looks like what you've got! Thanks for the information Al Dente! -Joe Illigitimati non carborundum Fruitbat's PDF Library Link to comment Share on other sites More sharing options...

I am from that time when this tooth was thought to belong to some rostral teeth of a sawfish . Dermal denticles? Which animal? Of some fish? I did not know this theory yet. Where can I find this information? Any publication? Hugs! Is It real, or it's not real, that's the question! Link to comment Share on other sites More sharing options...
LordTrilobite Posted September 10, 2017 Share Posted September 10, 2017 The first one is labeled correctly. The second one is indeed a lunfish tooth. It should be labeled as Neoceratodus africanus. The third fossil is a Pterosaur tooth. It should probably be labeled as Siroccopretyx moroccensis. Though some consider this species synonymous with Coloborhynchus as it's quite similar. That's why you sometimes see teeth from Morocco labeled as such. 2 Olof Moleman AKA Lord Trilobite Link to comment Share on other sites More sharing options...

There is a modern ray with very similar dermal denticles. It is the bowmouth guitarfish (Rhina sp.). 1 Link to comment Share on other sites More sharing options...

Haravex Posted September 12, 2017 Share Posted September 12, 2017 all of them fossils you have are real, the first one I believed to be a rarer type of sawfish, however someone pointed out a debate about it being a dermal denticle, the second is a lung fish and finally the crown jewel for me the siroccopretyx tooth it has the characteristics of a genuine one and identified as such (vertical like serrations at the bottom, running to smooth at the tip curve looks good) and there is still matrix attached which looks kem kem typical. 2 Link to comment Share on other sites More sharing options...

-Andy- Posted September 12, 2017 Share Posted September 12, 2017 Although I can't speak for the identity of the first two fossils, I would say all three are right proper teeth, and not frankenteeth. I presume the pictures are taken from the seller? If it's the same one I am thinking of, he's reliable. 1 Looking forward to meeting my fellow Singaporean collectors! Do PM me if you are a Singaporean, or an overseas fossil-collector coming here for a holiday! Link to comment Share on other sites More sharing options...

I believe that for these photos you already know who is the seller... But yes, he is very trustworthy, I have done several shopping with him since he works with fossils from my preferred fossiliferous area; Kem Kem beds. Thank you all very much for your input, it is very much appreciated my friends -Andy-, Fruitbat, Al Dente, LordTrilobite and RJB. Is It real, or it's not real, that's the question!
