magicalmrmerlin Posted November 27, 2018 Share Posted November 27, 2018 I have recently been given a number of shark teeth by a relative who used to collect. I would appreciate any help that members might be able to offer. I will post 3 photos. On the first photo am assuming the 4 on the left are Sand Tiger and the middle bottom 2 are Odotus? Unsure about the rest. Link to comment Share on other sites More sharing options...
magicalmrmerlin Posted November 27, 2018 Author Share Posted November 27, 2018 Again I am assuming the 5 on the bottom are Odotus of some description. Unsure about the others. Link to comment Share on other sites More sharing options...
magicalmrmerlin Posted November 27, 2018 Author Share Posted November 27, 2018 The bottom 3 are fairly obviously 'meg', to my uneducated mind anyway , but what about the others? Link to comment Share on other sites More sharing options...

Unsure about the others. Bottom five (5) teeth appear to be Otodus obliquus, probably from Morocco, based on color. Top Row - # 2, 3 & 4 from left appear to be some species of pre-megalodon. Need to know location and geologic formation to make a definitive ID. Tooth on top, right appears to me to be a worn Hemipristis serra. 2 Don't know much about history Don't know much biology Don't know much about science books.........

Unsure about the rest. Your ID on the Sand Tigers and Otodus appears correct to me. Top row - tooth #3, 4 & 5 and bottom right tooth appear to be some species of pre-megalodon. Still need to know general location and geology to make a definitive ID. I will say, the tooth on the top row, second from right (tooth #4) has very interesting morphology on its left side, at the top of the blade. Not sure I've seen a cusplet like that. @sixgill pete @ynot @Plax Don't know much about history Don't know much biology Don't know much about science books.........

First one on the bottom row does not look like a meg to me, but the other two on the bottom row do look like megs. Definitely two great whites in the middle top row, maybe a chubutensis top right?

magicalmrmerlin Posted November 27, 2018 Author Share Posted November 27, 2018 Thanks very much for your help SailingAlongToo. These teeth have been sitting in a box in a mixed box of fossils someone's garage for years, so it is virtually impossible to know exactly where they all came from. I am guessing the majority come from Morocco, other than the meg ones. I have others in my cabinet from the same person, so I might post some more photos here in due course.

Unsure about the rest. Sand tiger ID looks right to me. Top row middle tooth looks like an angustidens or chubutensis to me, but I’m no professional Link to comment Share on other sites More sharing options...

Top row- angustidens or chub, followed by 3 auriculatus? Last tooth on the top row almost looks like a benedini, but those don’t have serrations and yours looks like it does.

Tidgy's Dad Posted November 27, 2018 Share Posted November 27, 2018 Yes, nice Moroccan shark teeth from the phosphate deposits, probably from Khouribga. Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...

As a note to the poster, it really helps with the id process when you add numbers to your photos for each tooth when you post a large number of teeth for identification. Also your lighting could have been better because of shadows and bright spots in your pictures. Your lighting distorted the tooth colors and made some tooth features that are important for an exact id difficult to see. Flash can add shadows and bright spots that hide important tooth features. Strong natural lightning works well in most cases. Luckily most of your teeth are pretty distinctive so the pictures were adequate to id most of them.

Unsure about the rest. Sand tigers are correct. 2 middle bottom look like Otodus. Top 3 on the right look like Paleocarcharodon orientalis. Bottom right something in the meg lineage possibly. Need better pics of that one front and back.

Daniel_63 Posted December 1, 2018 Share Posted December 1, 2018 Hi, I read a lot of thing but on my opinion, to give the best identification for fossils, it is very important to give the site (or the country, or the town) and the the period + Age + formation. If you are these informations I sure that it will be easy to help you. Link to comment Share on other sites More sharing options...
