Hello everyone, I am a bit late to post this as my trip was over a week ago (13 oct) but better late than never I guess. For this trip I had gone to west Qatar, which is on the other side of the country but only about an hours drive. (Pic from previous trips) About the area: It is entirely composed of lutetian rocks, and the valleys in-between the hills are mostly composed of eroded remnants of the midra shale formation, and leaving big teeth concentrated at the surface. The hills are of a different formation, I am not sure what the name is but only invertebrate fossils can be found on them. I had been to this locality thrice before with no luck (0 teeth were found, only 1 stingray barb) so this time I thought to try out some UV hunting at night. So far all my teeth finds were only sourced directly from a bulldozed mound of midra shale fm rocks, where big teeth, especially odontaspis, serratolamna, galeocerdo and pristis rostral denticles are rare so my main goal was to find some of these. Heres how they looked under UV light: All my finds: The biggest one (top left) is about 3.5 cm (for scale). All these were found within an hour of surface searching, but the myliobatis mouthplate, posterior odontaspis tooth, the sphyrna tooth embedded in matrix and the thing in the lower right corner was found from the bulldozed midra shale area(the one I referenced earlier) which is around 10 minutes away from the surface hunting area. My best finds: 1. Pristis lathami (I joined 2 fragments I found using some clay(temporary), I am not sure if both pieces are associated or not) 2. Odontaspis winkleri 3. and 4. Serratolamna 5. Myliobatis mouthplate 6. Posterior odontaspis 7. Eotrigonodon 8. Pycnodus sp. Cf. mokattamensis 9. Dugong bone (prorastomus?) 10. Propristis schweinfurthi 11. and 12. Galeocerdo latidens 13. Shark vertebra I did not expect this level of preservation from surface finds, especially the 11th, 2nd and and 1st one and many of the other finds in the previous picture, so I think I got very lucky with finding a recent exposure I am unsure what this one is, its the same size as the myliobatid jaw and I guess its some sort of crusher teeth jaw Also for some reason, when looking at my pristis rostral denticle from below, it does not show that indented flat region, maybe because it only shows up when its more larger? Close up of the myliobatid mouthplate shows the interlocking structure of the teeth, I always wondered how the teeth stuck together Well thats the end, thanks for reading!

***Need professional help with Paleogene/Eocene shark teeth identification***
Morte posted a topic in Fossil ID
Hello everyone!)) Need help of paleontologists and paleoichthyologists with identification of eocene shark teeth from Russia. I'm not professional, just a fan and rooky, so I choose possible species options for every tooth, according to books and scientific publications which I have. Hope I make right something at least. Be glad and thankful if somebody will help me figure it out)).- 3 replies

This tooth was collected from one of the Monmouth County, NJ, mixed Miocene/Eocene sites. The curved shape makes me want this to be a Parotodus benedeni, but it could just be a weirdo Odontaspis, Carcharias, or one of the other more common types of sharks. Would love to hear what you all think.
