FossilHunterNYC Posted June 15, 2020 Share Posted June 15, 2020 Bought this awhile ago can someone tell me if it’s real or not and what possible shark it came from? Link to comment Share on other sites More sharing options...
Praefectus Posted June 15, 2020 Share Posted June 15, 2020 It is real. Otodus obliquus shark tooth. 3 Link to comment Share on other sites More sharing options...
Fossildude19 Posted June 15, 2020 Share Posted June 15, 2020 I agree - Moroccan Otodus obliquus.

Praefectus Posted June 15, 2020 Share Posted June 15, 2020 They are distantly related. Both Otodus obliquus and the great white shark are lamniforms and they likely shared a common ancestor during the late cretaceous (Cretolamna sp.). Otodus obliquus is the direct ancestor of megalodon and the other megatooth sharks, but not the great white. White sharks are thought to have evolved from early makos. 1 Link to comment Share on other sites More sharing options...
Lihaaja Posted July 1, 2020 Share Posted July 1, 2020 This topic is littlebit old, but i think you could get some more features to show if you want. I bought similar otodus tooth some time ago and it looks like it is in similar matrix as my specimen. First thing i did, i took some dental picks and tools to get that other cusp to daylight. Its quite easy first prepjob even for a firsttimer just like me. If you prep that red circle area, it could look much nicer. Link to comment Share on other sites More sharing options...

I’ll give it a try I just realized, that actually my profile picture shows the final result. I prepped that cusp close to camera to daylight. Just the tip: Even though enamel in teeth are quite hard ( I tested it by "trying" to scratch it with my tools, just to be sure how careful I had to be. I couldnt get a single scratch. ) Try not to hit it with your own tools. My thoughts are, even if it doesnt get scratches or marks, its better to learn to be careful right from the start so. It pays off with later, when dealing with more fragile specimen. Link to comment Share on other sites More sharing options...

It pays off with later, when dealing with more fragile specimen. Very good prepping tips! You can even use wooden toothpicks, if the matrix allows (sometimes copiously applied amounts of glue may harden the surface to the extent it's difficult to get through), which will cause even less damage if it hits something. Use a sharp needle or dental hooks to remove the matrix, preferably under magnification, and keep your other hand close to the needle-tip to prevent it from overshooting it's target. Use finer needles for finer work, course hooks for courser work. Finally, be aware that, though it does appear more of the tooth may be hidden underneath the rock in this case, that's by no means a guarantee. With Moroccan fossils the general rule is you buy what you see - and if there's anything more to it, that's an added bonus (i.e. the tooth could just as well be a partial). Just to be forewarned.

aeon.rocks Posted August 4, 2020 Share Posted August 4, 2020 The enamel is hard, but carefull with the softer roots on these. Quote With Moroccan fossils the general rule is you buy what you see... Only with Moroccan fossils? That rule should be applied to USA fossils aswell, parafrized as "pay for what you see, not what sellers want you to see". 1 Link to comment Share on other sites More sharing options...
