    Shark teeth ID help

    Hi. I'm a final year undergraduate student doing my dissertation on sharks. There are a few teeth I found which I feel I should be able to identify given some features preserved, and I don't want to just leave them as indet. They were found at Walton-on-the-Naze, UK, from the lowermost London Clay Formation, Eocene (Ypresian) in age. All photos show teeth in the best view that I could capture with me camera/have most of the specimen in focus. Scale bar on the right = 1cm. For all teeth they are in lingual (left), labial (middle) and mesial (right) views where applicable. Apologies for the lateral photos being so blurry, didnt get the chance to run them through focus stacking Thanks in adavance. Also, if people want to ask me any questions on the disso feel free to.

    Morocco 2023 Geology Trip

    I was fortunate enough to be able to visit Morocco last year in May and tour the wonderful geology of the country. This will be a very short recap of the experience because frankly there are just too many things to share. For starters, the culture is fantastic. Morocco consists primarily of the Berber people and they are some of the friendliest people I've encountered. Very welcoming and ready to share some tea with you. Tea is by far the most common thing you will drink in country. I'm quite certain there were days that I had tea at least 8 separate times, and the tea was fantastic. If you've never had Moroccan tea then you are missing out (the mint tea in particular is wonderful). The cuisine is beyond amazing, and there honestly wasn't anything in country that I didn't like. Trying to replicate some of the foods has been a challenge (my tagine is getting close), but I suppose that just means I'll need to return some day. The country is also very safe throughout. As a solo female traveler, I felt comfortable at all times and was not concerned. However you should know that few people speak English. The most common languages people know are Arabic, French, and Berber, so there was some language barrier but as with most things, it was doable. My arrival to Morocco began in Marrakech where I was met by my guide who drove me out of the city, through the Tizi n'Tichka mountain pass at 2200m in elevation. Eventually we made our way to Tamdahkte and I stayed at a wonderful riad that was (as I would come to find out) quite open air just as most riads and buildings are in Morocco. On the way we stopped at a salt mine and walked through.

    Nautilus from Oman

    Hello, I managed to obtain this nautilus from the internet. The former owner told me she got it 60 years ago from an employee from Shell. He took it from the desert in Oman. He told her, there where many more fossils to find there, but that the accesibility was very complicated. She could'nt tell me the age from the deposits. So I tried to google some information. At first, looking at the pictures I thought about a jurassic nautilus. But the more I am diving in to search the possibilities and the fact that it is quite slender for a nautilus I'm leaning towards a Eocene nautilus. Deltoidonautilus would be a possibility. It is 27 cm. Can anyone help me with the ID, or pherhaps put me on a good path to find it? Greetings Walter

    Eocene shark teeth ID?

    Good morning everyone, I think a couple of people of this forum already posted some of their finds from the Arabian peninsula (Saudi Arabia/Qatar) here but here are some shark teeth that I’m struggling to ID. mom thinking that those might be some kind of Brachycarcharias? Thank you guys for your help!

    Hypsiprisca sp.

    Juvenile Priscacara can be easily distinguished from juvenile Hypsacantha by their distinctly rounder body shape. Grande distinguishes two forms of Hypsiprisca: Hypsiprisca hypsacantha (originally described by Cope in 1886 under the name Priscacara hypsacantha) and a second yet undescribed, closely related form Hypsiprisca sp. H. sp. is more common than H. hypsacantha: H. sp. are mostly very small individuals less than 60mm long. Quotation L. Grande (2013): "The second species that remains undescribed differs from H. hypsacantha in being more slender-bodied and having a more convex posterior tail fin margin (H. hypsacantha has a very slightly forked tail margin)." References: Whitlock, J. (2010). Phylogenetic relationships of the Eocene percomorph fishes †Priscacara and †Mioplosus Journal of Vertebrate Paleontology Volume 30 – Issue 4, pages 1037-1048.

    Nice Little Ric from Today

    Went to my private pit today for about an hour to gather some micro material. While there I walked around just a bit picking up 30 or so loose teeth. Some Striatolamia, Galeocerdo, Anomotodon, Abdouinia among others. Also 2 Hexanchus and this realy nice little Otodus auriculatus.
  10. It was too cool and windy, for 2 hours of walking and looking for surface finds in a great wide open area 2-4-24; but I guess I heard that old siren's call again?
  11. I found this tooth a while back in a small private agricultural marl pit I have been hunting for a few years. It is Eocene Castle Hayne Formation in eastern North Carolina. This pit has produced roughly 26 species of Eocene sharks, including multiple Hexanchus, C. auricualtus up to 3 1/2 inches; sea snake verts, large amounts of Pristis fossils among other items. It also has yielded multiple archaeocete whale teeth and verts. I originally thought this was a small whale tooth, but it just didnt seem right to call it whale. In Oct. at the annual NCFC Fossil Fair in Hickory N.C. I had it on display. Retired Smithsonian Paleontologist Dave Bohaska said he thought it was "sea cow" He took multiple pics of it, but I am still awaiting his replies. I have been doing some research on line when I came upon this archived thread. What do you guys think? @siteseer @Boesse Adding pics in next post

    Perhaps Myrtaceae?
  14. I have been collecting a locality in SC that is Eocene (Priabonian) in age. I have found a squalid tooth (I personally find it most favorable to Squalus weltoni) and 3 squalid-like teeth, however I have no idea what these could be. Unfortunately, the deposit is not kind to the fossils contained therein so they are quite beat up and missing the enamel. The definite squaloid tooth is the bottom one on the graphic, and the other 3 (top and middle in the graphic and the standalone) remind me of a squaloid at first glance, however don't appear to be. There is only one paper on the selachian fauna of this deposit, and there are no teeth comparable to these in said publication. The age is Eocene, Priabonian and locality is in Aiken, SC. The standalone is the same size as the top one in the graphic (~5mm). Any potential leads welcome!

    Squatina sp.

    This specimen was collected from a locality in Aiken, SC that I discovered in mid-2023. This locality adds to the very limited known exposures of fossiliferous Dry Branch strata in the Aiken region. Squatina are an uncommon find in these exposures, and finding one of such quality even more so. It can be seen how the glossy enamel has been leeched away leaving the dentine core, something discussed in Cicimurri and Knight's (2019) publication. In the aforementioned publication the authors tentatively assign the species to Squatina prima "...specific identification is tentative because of the small and imperfectly preserved sample". Because their identification was tentative I will refrain from making a specific identification. References: Cicimurri, D. J, & Knight, J. L. (2019). Late Eocene (Priabonian) elasmobranchs from the Dry Branch Formation (Barnwell Group) of Aiken County, South Carolina, USA. PaleoBios, 36.

    Notorynchus sp.

    Cow sharks are quite uncommon in this deposit, and even moreso it is exceedingly difficult to find one of good condition due to the nature of fossilization. The only species known from this deposit is likened to Notorynchus kempi by Cicimurri & Knight (2019), however they refrained from making a definitive classification due to lack of specimens and poor preservational quality. References: Cicimurri, D. J, & Knight, J. L. (2019). Late Eocene (Priabonian) elasmobranchs from the Dry Branch Formation (Barnwell Group) of Aiken County, South Carolina, USA. PaleoBios, 36.
  17. Looking for thoughts of what this might be. It was found in Bastrop County, Texas and was found in a formation I can only date to the Eocene. It was surface collected after eroding from a layer of ironstone, the specimen being much denser than ironstone. Although likely not the case, the wavy straw-like structures (that are approximately 1mm in diameter) remind me of the coralloid roots found on a cycad or the vascular structure of a palm. There do appear to be rings or layers visible in the cross section. The scale shown in the photograph is in inches. I appreciate any and all attempts to identify. GB

    Boverisuchus sp.

    From the album: Eocene

    Boverisuchus sp., South TX Lutetian, Eocene Jan, 2024 Upon first glance, one could mistake this for a non-avian dinosaur tooth due to its serrations and compressed shape. You would be in good company as many early paleontologists made the same mistake. As it turns out, this terrestrial Eocene croc may have filled a similar niche to what was left behind when small theropods went extinct. To make this animal extra weird, it had hoof-like toes and appears well adapted for running down prey like dog-sized four-toed horses. Formerly known as Pristichampsus, the genus Boverisuchus was recently resurrected to encapsulate the running crocs found in North America.

    Chinatichampsus wilsonorum

    From the album: Eocene

    Chinatichampsus wilsonorum, South TX Lutetian, Eocene Jan, 2024 Well I hunted a new site this weekend and I must say it's pretty spectacular. This is the find of the day for sure. Chinatichampsus is my best guess. This genus was described recently from the Eocene of the Chinati Mountains in West Texas. The teeth I found exhibit a wide degree of heterodonty and fearsome serrations. Posterior teeth are bulb shaped and gradually become pointed moving anteriorly. This tooth was somewhere in between the extremes.
  20. Hello, Another weird fossil found in Al Ain close to Jebel Hafeet. It's very detailed and tuberculated all over. Looks similar to some crab pieces I've seen.
