  1. Heres a fun thread for those to show off their widest and fattest looking megalodon teeth fossils in thier collections. I'll set the tone with the widest fat boy in my collection, I don't have digital calipers but it measure roughly 5.4 inches wide by 6.1 inches long. When I close my hand together it looks even more monstrous. Share yours and join the wide boyclub Got the idea while thinking about what the widest megalodon tooth ever found measures, if anyone does know do share in this thread!
  2. These are some bits of coral and a shark tooth I found on the beach at Myrtle Beach, South Carolina, this morning. Obviously there's not much geologic context, so I don't expect much, but can anyone tell me more specifically what they are? Or how old they are (are they even actually fossils?)? The scale bar in the shark tooth photo is about a centimeter.
  3. Processing some micro-matrix from a creek here in Florida and I've come across a number of tiny chondrichthyan (assuming shark) teeth that are rather odd and defy my efforts to classify them (not really all that difficult). You can see from this gallery of 9 teeth that they tend to have fairly thick wide roots (when they are not eroded away). The enameled crown is wide at the base and has a single cusp that is curved becoming nearly parallel to the root base. Often, these oddly shaped smaller teeth end up being odd symphyseal (or parasymphyseal) teeth of a more common species since teeth in t
  4. I've got this unusual shark tooth from a Florida creek that has side cusps. At just over a centimeter in length it is way to small to consider any of the megalodon ancestors with side cusps. Also, no real serrations apparent on this tooth though it is a bit water worn. The root doesn't really look right for a Sand Tiger Shark (Carcharias taurus) tooth (not even one of the more blade-like posterior teeth). Those have very thick bulbous roots that still show some of the U-shape of the anterior teeth. https://en.wikipedia.org/wiki/File:Carcharias_taurus_teeth.jpg Ric
  5. I just bought this megalodon tooth online, and I was wondering if someone could help me out and see if it’s real. My main concern are these notches/dents on the sides of the tooth (close to the root). It kind of makes it seem like it’s been molded. I’m not sure if this is natural or not.

    Angi or Rik shark tooth?

    Purchased on Etsy as a angustiden…but I now believe it might be a subariculatus. South Carolina origin. Thoughts?
  7. As promised, my second trip report covering my day trip last October to the two most famous Pennsylvanian-aged fossil locales in Texas is here! That same Saturday after visiting Mineral Wells and finally finding my first trilobites I made the hour drive north to Lake Jacksboro. For those who don't know, the Lost Creek Dam on the southeastern side of Lake Jacksboro was constructed from earth dug out of a borrow pit a short walk away. As the lake and its dam happen to sit on top of the Finis Shale Member of the Graham Formation (although there is debate that , which dates back to th
  8. Is this shark tooth Benedini or Mako? I found this tooth on the beach, north Florida area. The back of the tooth has mineral/rock buildup that I haven't removed yet (and not sure how I would remove it)
  9. The genus Centrophorus sp. represents a very interesting group of sharks within the Centrophoridae (Squaliformes), which can be found up to about 3000m below the sea surface. The largest representatives of this group reach a body length of 170cm. Not only because the sharks of this group are among my favorite sharks, but also because fossil finds of this species are extremely rare, I decided to write about this topic and compare fossil and recent Centrophorus species with each other, as well as collect the known information about them. The modern genus Centrophorus has been repeatedl
  10. I'm looking to buy this Great White Shark Tooth and I just wanna make sure its real. If someone could help me out I would super appreciated it.
  11. Hey everyone, just joined the forum to ask for opinions on this item. I was out on my Native American Reservation in Parker, Arizona and walking along the beach of the Colorado River outside of our Casino. I stopped to find some cool stones in the water and came across this thing that I immediately thought resembled a shark tooth. I’m no expert, but things like this tend to pop up out in Arizona. I reached out to a department at the Los Angeles Natural History Museum, seeing as they are only a 20 minute drive from where I live, but I haven’t heard back from them yet. Any thoughts?

    Corolla NC Shark Tooth ID?

    We don't get a lot of shark teeth in Corolla NC. So far we have a juvenile great white, sand tigers, lemon and bull. Can you help me identify the one I found this weekend? Is it a bull shark? Also, what causes the beautiful rust colored tip? Thanks, everyone!
  13. Sunday morning we went to Stratford Hall to do a fossil hunt with the Natural History Society of Maryland. The weather was not on board with the idea lol. It was barely above freezing and quite windy. Also tip for everyone if you buy waterproof winter gloves from Amazon double check they are waterproof. 3 out of our 4 pairs were, my oldest son's gloves were leaking at the fingertips. Also it turned out our hand warmer packs wouldn't activate when we opened them. Even though we didn't stick it out long we did find a pair of worn shark teeth and a pair of ray teeth pieces. After we got dri
  14. Found these teeth several days ago on Bolivar Peninsula,TX (Holiday Beach subdivision). My understanding is that shark teeth can be difficult to ID down to exact species, but am curious nonetheless (my guess for the bigger one was bull, other two mako or lemon). Thanks in advance for any expertise!

    Shark tooth ID

    While getting together some fossils for the rolling auction I came across this tooth I had bought a few years ago. I dug around on my folder of screenshots I take of fossils listings, so I don't forget what information the seller provides and it was pretty devoid of info. It was sold as a megalodon tooth. No location or any other info...yeah I know that would be handy... I assume but the looks of it, it probably came from the Carolinas or Florida. On to my observations. Seems to be no serrations on it. It looks like a nutrient pore in the center of the root on the lingal sid

    shark tooth or rock??

    Hi! So I know absolutely nothing about fossils, but my dad and I were looking for shark teeth at Fossil Beach in Westmoreland State Park yesterday, and we came up empty handed except for this weird looking rock. At first we thought it was just a rock in the general shape of a shark tooth, but upon closer inspection we noticed that it looks glossy and about the right color in a few spots (especially on one side) and there are some lines in the rock that look sharktooth-esque. It has holes in the top and on the side that are each about a centimeter deep, so we were wondering if it were possible

    Megalodon tooth

    From the album: Shark Fossil collection

    Beautiful Meg tooth with razor sharp serrations.
  18. @caldigger post on finding two pieces of the same tooth reminded me of the tooth I found in New Zealand many years ago. The site is closed now, so I don’t think there is a chance of finding the root. But is there anyone on here that could accept this challenge? I’ll pay of course! Tooth overlying picture of complete tooth of same size and position showing the missing root. The slightly trickier bit is on the back where the root/enamel transition is partially missing. Scale bar = 2 inches total. A few more images of the tooth;

    Shark tooth ID

    Can anyone tell me what type of shark this came from? I found it in Caspersen, FL. It’s 3/4in.
