    Fossil id (Calvert MD)

    Hi! First, thank you to everyone who responded to my older post asking for fossil hunting tips- I used as many as I could and I found some great stuff! Here's what I found and can't ID myself from my latest trip to Flagponds (Calvert MD). I was thinking 11 might be snaggletooth shark, and 19 and 20 looked like they might be from some kind of white shark though I'm not entirely sure? In addition to those I'm especially interested in identifying 1, 3, 4, 5, 8-9, and 13 but haven't been able to so far. I'd appreciate any help identifying these and the other teeth I have pictured! 36-48 are

    Calvert Beachcombing Tips?

    Hi guys! So I'm planning to go back to one of the Calvert County beaches to try my luck again- I haven't had any success with finding teeth bigger than about a quarter inch and I'm hoping to find something a little bigger next time. My current technique is to dig up sand from the water and sift through it super carefully- should I switch it up and try something different to find big teeth? If so, does anyone have any recommendations for how to find them? And, final question, which beaches are good for finding larger specimens? I know Purse and Matoaka are good for quantity but I don't know whi
  3. In the last couple of months my son and I have purchased some unprepped Lebanese fossil fishy's. There are four known species of guitarfish from the Lebanese provinces of Hakel and Hajula. Rhinobatos maronita is one of these; this species was fist described in 1866 by Pictet and Humbert. Some purty dang cool stuff but the guy we are buying from does not know how to wrap and send fossils over seas! Our last shipment came in many pieces! Not good. My son is working on him to make it right? Aside from that Im going to do what I can to fix things. First up is one side of what I think is

    Calvert County Fossils

    Hi everyone! I went to Flagponds in Calvert County MD a few weeks ago and came back with my biggest *actual* fossil haul so far (I posted here my first time with about 50 barnacle pieces)! I know there are a few ray plate fragments in here, and I've included what I think are bone pieces although I'm not entirely sure. Anyway, I'm having a lot of trouble identifying my shark's teeth, so any help with this would be greatly appreciated! I'll post numbered photos of my finds with this. If anyone needs a zoomed in, clearer or different angle pic I'm happy to provide more. (Advance apologies for the
  5. Hey there folks, I am cataloging some specimens I collected back in 2008 from the Bergstrom Formation of the Navarro Group in Travis County, Texas. I have some great papers on the invertebrates but not the vertebrates. The age is Maastrichtian. In particular I have a rather nice Enchodus tooth and some small, but well preserved, shark teeth I am trying to ID. I have the Walton & Farrish book and have visited Oceans of Kansas but they are still not getting me where I want to be. Thanks up front, Erich

    Fossil Shark ID help please.

    Hi folks. My turn to ask for ID help. I’m more of a dinosaur tooth and fossil guy. My friend gifted me these fossil shark teeth. Can you take a look and help me with these? I own a couple Meg teeth and other Shark teeth, but these are giving me a little trouble, or I’d like verification. The first two (A) and (B) have a bourlette, but proportionately large serrations like a Great White. Except GW teeth don’t have bourlettes. I believe (C) and (D) May be Carcharocles hastalis. Are they? I believe (E) is a Mako. But what species? Lastly, is
  7. Not sure where this belongs, but for those of you that are shark fanciers I recently found that the definitive guide, "Sharks of the World: a fully illustrated guide" by David A Ebert, Leonard Compagno and Sarah L Fowler with illustrations by Marc Dando is being published with 80 additional pages in October. If you have been looking for a copy you may be aware that the 2013 edition currently sells for a ridiculous $600 to well over $1000. (Best I can find right now is $591) You can preorder a copy of the new expanded version now
  8. Mysterious event nearly wiped out sharks 19 million years ago By Yasemin Saplakoglu, Live Science, June 3, 2021 "It's unknown whether the ancient sharks died off in a single day, weeks, years or even thousands of years."

  9. Last summer I posted a trip report about finding some Pennsylvanian black shale in a river bed in East Central Illinois http://www.thefossilforum.com/index.php?/topic/106753-628-illinois-black-shale-trip-w-listracanthus/. I was able to visit the site again once more in the fall last year when the river was running much lower and collect more and larger pieces of the finely bedded and fissile shale. Since then I have been slowly splitting and going through the rocks I brought home, and finding many interesting fish parts- that is definitely the dominant fauna presen

    Shark Teeth St Augustine Florida

    Ok I was lucky to find these shark teeth in St Augustine last week. But help with identification please. My guesses are Mako top left followed by Sand Tiger and lastly a small Great White? Or could that be an extinct Mako? Thanks for your help.
  11. Are Isurus praecursor and Macrorhizodus praecursor synonyms? I have conflicting accounts on this and would like clarification please. Thank you, Bellamy

  13. 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!

  15. Good evening to all participants! I have accumulated a lot of local (from Ukraine) material - I decided to sort it out, and recurring fossils, or not of interest to me, offers you an exchange. Everything in the photos is one lot. Consists of: 1. Tile from Carboniferous period with fern print; 2. A fragment of the armor of a armored fish Podolaspis Lerichei of the Devonian period; 3. Tile with Silrian brachiopods and tentaculites; 4. Mollusk of Neogene; 5. A small fragment of a fossilized araucaria of the Carboniferous period with quartzite crystals; 6. 2 fragments of orthocer

    Shark Tooth ID - Florida

    Please help ID any of these sharks teeth that were collected from the west coast of Florida (near Venice) this past weekend. Based on my research, the top two rows look like Sand Tiger and the bottom two look like Lemon. Would this be correct or are there any that look out of sorts?

    Shark Tooth ID - Florida (Part 2)

    Please help me ID these shark teeth that were found on the west coast of Florida (near Venice) over the past weekend. My belief is that the top row could be Great White and/or Megalodon (very nice serration on the largest/first one), the second row is either Bull or Dusky, and the third row is Hemipristis (Snaggletooth). As for the fourth row... the jury is still out. I am most intrigued by the third/tiny one (from left to right). It looks different from anything else I have ever found. Very compact, lots of detail, and oddly shaped. Any ideas???
  18. Hey all!!! Been a long time since I posted on the actual site. I'm doing Christmas in Bonita Springs, Florida this year and would love to do some shark tooth hunting. I'm not familiar with Florida fossils at all. SO! I'm starting my research and thought I would take in any recommendations to work around. let me know and I'll share!!! Thanks!
  19. Can anyone please help me in identifying this tooth? I’m leaning towards an extinct sub species of the great white however I cannot be sure.. any input would be greatly appreciated

    Shark Tooth Found

    I found this tooth at my normal overburden site, at work, it is the best shark tooth i have even found. Looking at Shark tooth I.D guides my guess is that this is a Auriculatus tooth. What do you all think?
