    Florida Coast Fossil Plant?

    Hi! I found this oddball fossil on Caspersen Beach in Venice, Florida. It’s nearly 2 1/2” long with serrations on two sides. It’s got my curiosity up.
  2. While out on one of the small "islands" off the coast of Wrightsville Beach, Wilmington, North Carolina- yesterday morning I found this tooth. I have quite a few teeth and various fossils but something about this one feels different. I'm sure everyone says that but I have gone through various shark i.d. questionnaires and can't get a specific conclusion. I've had suggestions from an ancient "cow shark" type species (I think bc I answered "yes" to present cusplet) but there is clearly one and it doesn't appear another broke off- which makes me think age is a factor (as in this could've belonged to a juvenile as opposed to an adult). The back is not completely flat but no serious pronounced shapes, the root is large and in tact with no visible foramen (in human biology a foramen is basically a hole so I'm making the same assumption or odontological guess) and there is not a nutrient line, crown and neck present, serrations continue on both sides of the tooth (I am including two copies of the same photo to show the original with a shadow; but if magnified the serrations are more clear and then a clearer shot that unfortunately didn't 'cut' the black shadow from the serrations. A genus I keep finding is Carcharhinus and hopefully someone has some ideas. Cheers! Becky

    Three tooth fossils

    These teeth fossils are from an auction Lot and sadly they have been battered around - the curved tooth has had the tip recently broken (and lost!) and another has been snapped. The vendor knows nothing about them, he bought them as part of a large mixed pot of other stuff. The curved tooth has beautiful serrations on both the inner and outer edge. The other two teeth have a ridge running down the inner and outer edge. I love the form and ‘sculpting’ of them, but fossil teeth aren’t my thing. Any ideas?

    Unknown Serrated Moroccan Shark Tooth

    I was going through a number of common Otodus teeth for sale at a local rock show and found one with large serrations on the sides. Doing a little research showed two types of serrated shark teeth from Morocco. Otodus sokolovi and Palaeocarcharodon orientalis. The tooth is 3 1/2 cm long on the diagonal. Sorry for the poor photo. My camera isn't the best but you can make out the serrations. Can anyone identify this?

    Carcharodontosaurus or Deltadromeus tooth?

    Hi, I am new to this forum. I have had an interest in dinosaurs since I was a little kid, but this has "matured" in recent years. Recently, I got a tooth as a present. It was bought as a Carcharodontosaurus tooth, about 19 mm long (0.75"), at a large exhibition/museum in Kalmar, Sweden. But since the creator of the exhibition managed to lable a (flattened) Mosasaur scull as a Carch as well, I am not too confident in the identification. The tooth is small, but pretty. Did it belong to a juvenile Carcharodontosaurus, a Deltadromeus, or something else? I would be grateful for any help on this. At the moment I do not know where it was found originally.

    Serrated Otodus tooth from morocco

    Recently bought this Otodus tooth from morocco. The tag said that this is a Otodus sokolovi, but I don’t know what is the difference between auriculatus and sokolovi or maybe thay are the same species? Besides, if we don’t know where the teeth came from, what is the difference between auriculatus and angustidens?

    Small shark teeth from SC

    Just acquired a small shark tooth, but not sure about the species. Need some help with identifying this one. It is serrated but not so obvious. I think it might be hammerhead, lemon shark, or carcharhinus sp?
  8. I’m not sure what species this is, but I think it’s more like chubutensis than megalodon.

    Venice Shark Tooth ID, Please

    Hello, newbie here! My son found this on our property in Venice, Florida. Our home backs up to Alligator Creek (original headwaters for Lemon Bay). Just moved to Florida this summer, so I have other posts to make as well - hoping you all will share your knowledge so that I can get better at knowing when I see something special and, overtime, learn how to identify some of these things myself (besides basic teeth like Lemon Sharks lol. Initial guesses on this were great white, baby meg (seems too small, but the shape and characteristics seem right), dusky, or extinct mako (just trying to do my part of researching first, but I am going in circles on it). Both sides are serrated from top to bottom. Couldn't get a shot at a good angle to show that the tooth is quite thick in the middle (rises to a clear high point in the middle when looking from left to right). Thank you all in advance!! Images in order: 1. Front 2. Right 3. Left 4. Left 5. Back (sorry, didn't realize it was blurry when I took it)

    Tooth Id

    Hey! Both of these teeth were found in the horseshoe canyon in the same place. I was thinking Albertosaurus but I don't know(They are serrated if you couldn't tell from the photos). Any ideas? (sorry for the low quality images)

    Beach fossil?

    Hello. I'm new here. I have read the guidelines for posting a fossil for ID and I hope I'm following them. I've had a good deal of trouble getting a decent photo of this with a scale, proper lighting, etc. I found this while looking for shark teeth on Hilton Head Island, South Carolina, April 19, 2010. Low tide, low surf, low wind. Good shark-tooth hunting day. Could this be a fragment of a large shark tooth? Thank you.
  12. Here is one of two serrated Spinosaurus teeth I recently acquired. Let me know what you think! The tooth is from Kemkem and is about 3cm in lenght. The serrations are very small, but still visible with the naked eye as I spotted this one on a fossil fair some time ago.

    Serrated Unknown (Croc?) Tooth

    Hola folks, Just picked up an itsy-bitsy, teeny-weeny tooth from the gift that keeps on giving; Morocco. It was sold as a juvenile Spino tooth, but I'm thinking there's a better chance of it being croc? I liked the look of it, so bought it anyway. Location given: "Hamada gu Guir, Kem Kem Basin, Morocco." Not sure if you can pick out from my crummy photos, but there are definitely denticles present on the carinae, running all the way from tip to base of the crown. There is also fluting present on both the labial & lingual sides of the tooth, running the full crown length. The cross-section appears to be roughly oval, though could be considered circular (it's hard to tell with the shape of the base). Denticles most noticeable in this one: Profile of denticles can also be (kind of) clearly seen on the right side of the tooth here: And a couple more shots: With the lingual curve and denticles, I'd assume croc from this part of the world, though I've read that labial/lingual curves can be found on Baryonychidae....if only haha! Any input on narrowing down exactly what it might be would be much appreciated.
  14. The piece measures to be .5 inches by .65 inches and I barely noticed the worn serrated edge, anyone have an idea what it is ?
  15. This was apparently published in September 2018, but it slipped past me and I’m posting it here in case it slipped past my fellow thresher lovers. The allusive serrated giant thresher has been named Alopias palatasi. Of course if you like Trigonotodus better, it is Trigonotodus palatasi. Now when I add one to my collection in the far far future, I can finally put a good label to it! Here is the description: https://www.researchgate.net/publication/327871783_Kent_Ward_2018_Alopias_palatasi
  16. Happy holidays everyone. I would greatly appreciate help identifying the following specimen. It was collected in the Santa Susana Mountains of Simi Valley, Ventura County, California. It came from the Saugus or Pico Formation. Saugus is late Pleistocene to late Pliocene while Pico is middle Pleistocene to Pliocene. My uncertainty regarding the exact formation arises from the fact that (1) it was float material already weathered out of the formation it came from and (2) based on limited research and knowledge, I believe there has been a lack of consenus regarding differentiation of the two formations (see recent work by Richard Squires et al. in Valencia and R. Squires in Newhall). I assume it is marine since all of Pico is marine and Saugus is non-marine to marine. At first I thought it was a shark tooth when I picked it up but I threw that thought out the window when I realized it had three serrated edges. Measures 22 millimeters long and 6.5 millimeters wide. It is 4 millimeters tall on one end and 9.5 millimeters tall on he end that has the needle structure. There are three to four 'bumps' on both long sides on the end with the needle. The bumps look evenly spaced. I can and will do my best to provide additional info if needed.
