    Hexanchid tooth ID

    Hey, going through some finds of last year i came across this tiny Hexanchid tooth. 0,9cm x 0,5cm, Miocene/Pliocene, Antwerp area, Belgium I've seen Hexanchid posterior teeth before and they look quite different.. (from the book 'Neogene Sharks of Antwerp' by Stephane Knoll) Could mine be juvenile Notorynchus or Hexanchus? Thx, Dries
  2. Hey hi Everybody! I like the unusual teeth. And posterior teeth are some of the most unusual in any given species. So I thought I would start a thread for posterior shark teeth of any species. To kick it off..... Here are some from Shark tooth hill (round mountain silt). I think these are Carcharodon hastalis and (?) planus. The smallest one is just under 1/8th inch wide. So, if You have any posterior shark teeth - please post pictures here. Thanks, Tony
  3. Today I went to a nearby creek in north Florida and came across these fossils that I need help identifying. 1. Definitely posterior. Maybe bull, lemon, or hammerhead? 2. I don't know if I've seen this before, at first I thought small hastalis, but then I noticed what appears to be a cusp on the left side. (it's just on the tape measure so you can see the cusp better.)3. Turtle, but I was wondering with the odd shape if it was possible to tell where from.Thanks!
  4. I found my smallest posterior angy yesterday (9 mm total height and about 3 mm crown height). One cusp is quite mangled, but I don't know how it has stayed together (and feels solid) if it was broken. My first guess was that it is damaged, but I wonder if it could be pathological. It appears in the first two pictures to have root material over the cusp area. Thoughts? Thank you!

  7. Hey everyone, Can anyone help me identify these two small juvenile posterior shark teeth that I recently found in Charleston, SC? Megalodon? Angustiden? Great White? Too hard to tell? thanks in advance!!

    Isurus retroflexus posterior tooth?

    After I remarked that the little tooth below (found on Morris Island, South Carolina) looked interesting on his trip report thread, forum member @Family Fun kindly gifted it to me, asking only that I help identify the species and share the result. My assessment is that this is an Isurus retroflexus posterior tooth, but hopefully others here can either confirm or correct that ID. This tooth has a non-serrated crown that is still fairly sharp and to my eyes at least has the raised labial platform indicative of I. retroflexus. There is a single cusplet on one side. Thanks for your help with this one, and thank you @Family Fun for your generosity! (Unfortunately, the tooth split down the middle on its journey to me, which is the crack you can see in the photos, but I was able to glue it back together.)

    Prognathodon posterior teeth

    Hi again I have a question what did prognathodon use it’s posterior teeth for I was just looking at a skull and they seemed different do they have a different use then the other teeth? @Troodon
  10. This tooth is a lower from the final tooth position (most posterior) on the left side as indicated by the bulge on one side of the tooth and lack of overlapping facet. The lingual face of the tooth is shown in the photo as indicated by the distinct delineation of the crown enamel and the root (less distinct on the labial surface). Teeth in a more anterior position have overlapping facets on both edges (with the symphyseal having both facets on the lingual face). The stratigraphic information for this locality is questionable and so is specified vaguely. The environment is marine shell hash that may span late Miocene-Pleistocene. Dr. Richard C. Hulbert, Jr. from FLMNH had this to say about the locality: There are two “formations” found near the surface in that area of the state. One is the middle to late Miocene Peace River Formation. The other “formation” possible is has been informally called the Okeechobee Formation by Tom Scott, and consists of the sandy shell beds formerly called the Caloosahatchee, Bermont, and Fort Thompson formations. On the geologic map of Florida published by the state’s geological survey it is not designated a formal name and is instead listed as Pliocene/Pleistocene shelly unit. Even if found in situ within the Plio/Pleistocene unit, such specimens could be reworked out of the Peace River Formation. If you are finding them in modern creek alluvium, it will be difficult to be sure which is their original depositional unit.
