  1. If you know anything about modern white sharks, how big are teeth of this size? The size is 58mm. How big was this great white shark? Are great white shark teeth of this size large?
  2. Hello all, I'm brand new to the forum and was hoping for some help identifying this tooth. It was found on the beach by my daughter in Cabo Pulmo area of Baja Mexico. She's excited to find out of it's a sharks tooth. We were not able to find anything close to similar through an internet search. Any help would greatly be appreciated!
  3. Just went to the natural history museum and found these in the display. I REALLY don't think this is great white shark? Might be in the same line (Otodus seems very similar) but I'd rather check with you guys before I ask the museum if they're sure that's what it is, lol.

  10. Hi All, I will be grateful for identification of late cretaceous (probably Maastrichtian) shark teeth found in Nasiłów, Poland. I know that some of the roots are missing and genus may be hard to identify but just the family will be enough in such cases. Thank you!

    Scapanorhynchis texanus?

    Hi everyone. I found this Upper Cretaceous shark tooth in Ramanessin Brook near Holmdel, New Jersey on Sunday. It is a little over half an inch wide. It appears different than any of my other Cretaceous teeth from New Jersey. My best guess- the common goblin shark: Scapanorhynchis texanus lower lateral. Most of my other goblin shark teeth (and there's many of them) are anterior and upper laterals. I do have some other lower laterals, but the blades are less slanted and taller. Still, they are the closest in resemblance. Or could it be a different species altogether? Any insight would be helpful. Thanks, and Happy Holidays! Sorry about the poor photo quality.
  12. Found this hastalis shark tooth in a florida creek was just wanting to share, but also wanting to ask whats the biggest lesser great white tooth people have found or personal found. Ive only been fossil hunting for two years but this is my personal best hastalis tooth its about 2.7 inches.

    Macrorhizodus praecursor

    M. praecursor is a relatively common find in vertebrate lenses of the Castle Hayne Formation. Leriche (1905) believing the species to be an Eocene version of the much younger Oxyrhina desori (Isurus desori) erected Oxyrhina desori praecursor. Leriche (1942) erected Oxyrhina praecursor americana for teeth with slightly different root and blade characteristics. These were placed into Isurus (White, 1931) and eventually a new genus, Macrorhizodus by Glickman (1964). Both praecursor and americana were accepted as distinct species (White 1956, Ward & West 1990, Zhelezko & Kozlov 1999 and Case & Borodin 2000a). Ebersole, Cicimurri & Stringer 2019 determined through studies of the extant Isurus oxyrhynchus that these different characteristics are attributable to heterodonty and placed americana as a junior synonym of praecursor. References: Ebersole, Cicimurri & Stringer, 2019.

    Shark tooth ID

    Wondering if anyone could ID this tooth from a south carolina creek. I found it a while back during a creek walk im more or less new to fossil hunting but im hoping its a worn down Parotodus benedini tooth. thanks
  15. Hi there. I found this on a field trip to a private quarry in Midlothian , TX (just south of Dallas). It was in limestone / shale in the ATCO formation, where there’s lots of shark teeth and fish bones. I’m pretty sure it’s been compressed as most of the shark spines I’ve seen are much more round and this is pretty oval shaped. Does anyone have any guesses as to species? Thanks in advance!

    Composite sets

    Hey been busy collecting teeth! I have refined my Obliquus set a bit. And tried to put together a couple of Serratolamna ascheroni sets as well. Any feedback, critique or advice on more references or other examples would be welcome.
