  3. Shark presentation

    Today was time for me to give my Shark presentation at the Onandaga County Free Library, in Syracuse, New York. Originally I was to do a presentation on sharks, for the kids in the morning, and a second presentation on New York trilobites, for adults, in the afternoon. Due to the death of a friend, I had to cancel the trilobite presentation to attend to funeral services. But I gave the presentation on sharks as I did not want to cancel that, and let the kids down, who had registered for this event with the library, in advance. I really enjoyed giving this presentation today. While I never claim to anyone about being an expert, I do enjoy sharing the knowledge that I do have, with others. There were about 16, of the 23 kids, who had signed up for this, as well as their parents. Not a large group, but that's ok. I talked a bit about sharks of the past, modern sharks, shark fossils, and how and where to find them. I only had an hour to talk, and the time seemed to fly by, but the smiles on the children's and parents faces made it rewarding. At the end of the discussion I gave each kid 2 sharkteeth and 2 stingray plates to take home.They all seemed very pleased with that. The teeth I gave away were all from my recent hunt from Cookie Cutter Creek, as I had plenty. The highlight was when one of the children approached me after the talk. She looked at me and whispered " You know, you talked just a little too much". I had to chuckle. I told her how much a appreciate constructive criticism.
  4. Big Brook Treats

    I wanted to post a couple pics from this weekend. I found a few teeth and things I am happy with. I could use a verification on the identities though. Thanks for looking!! Andy I think these 2 teeth are both Cretolamna Appendiculata. A very nice fish vertabra? And finally my favorite bivalve to find in the brook. I can't identify it for you though. It reminds me of the giant clam that tried to eat Batman and Robin back in the 60's.
  5. Hey everyone. I’m new to this forum and pretty new to hunting anywhere other than the beach, but I’ve been venturing out to Summerville and a few creeks in the West Ashley area. I’ve found pretty much nothing except for a broken meg tooth in a well known creek in Summerville. I’m not asking for anyone’s specific hunting spot, but does anyone have some insight on other areas besides the Sawmill Branch creek?
  6. Finally another fossil hunt!

    I’m quite busy these days, so it’s been a few months but I finally found a few hours to dart out and get a hunt in at brownies on Saturday. There had obviously been a myriad of collectors who braved the cold prior to me, so I wasn’t expecting much. However, I did end up with a few decent specimens. It feels good to get out into nature and climb over some trees once in a while. Despite my muted expression, I had a blast!
  7. Scapanorhynchus

    I want to tap into all of the expertise that is on this site again! I am doing research on a faunal assemblage of the Coniacian age from north central New Mexico. It is quite a large grouping, with over 12,000 teeth from over 25 species. I am currently working on scapanorhynchus, and am looking for some guidance. Some of the teeth have labial plications, and Cicimurri et. al. argues that this is most likely due to ontogenetic reasons. However, this paper is the only one I can find that even mentions labial plications on Western Interior Seaway scapanorhynchids. Do you have any thoughts about this? Any and all help will be greatly appreciated!

  9. I was reading a book about fossil fishes and there was a chapter dedicated to sharks and their cousins. Apparently there were chondricthyan scales found in the Late Ordovician and Early Silurian rocks. Since I hunt the Late Ordovician Georgian Bay formation in Toronto, Ontario and various Early Silurian formations in Hamilton, Ontario, what are the chances of me coming across these scales? Should I keep my eyes open and what should I look for?
  10. Sorry this is my first time in Morocco and I’ve never fossil hunted abroad if possible could any1 tell me what the teeth are (apart from the mosasaur one) and if the 2nd photo is a fossil or not

  13. New Jersey Modern Sharks

    Hey everyone, I recently walked on a beach near Keansburg, New Jersey, and came across an unusually large amount of dead animals. There were mostly crabs (blue crabs and spider crabs), baby shells, and jellyfish lying on the beach. However, I came across three small sharks. Does anyone know what factors might be responsible for the dead animals, such as rising water temperatures? If anyone knows what type of shark (I believe it is the smooth dogfish, Mustelus canis) and jellyfish that is, please comment. Thanks everyone, Joseph Jellyfish: Shark #1 body (with a fish behind it) Shark #1 dentition: Shark #2 remains: Shark #2 dentition:
  14. Does anyone know where I can find on the web a chart or table that lists shark species versus geologic time? I have searched but just can't find one. It would also be helpful if the table would show lineage as is presently believed to be accurate. Thanks!
  15. Help Identify Shark Teeth

    Hi everyone! I am new here. I found many shark teeth this past weekend in the Venice Florida beach area. I was able to identify all but these five teeth. Can anyone help me? I had not been to look for shark teeth since I was a kid and had forgotten how cool it was! I am hooked now and I want to go to the Peace River and the Carolina beaches to look for some Megaladon teeth! Thank you so much for any help you can give me! Jodi :-)
  16. Sharks Vertebras

    I received these vertebras form a lady that lives in Colonial Beach, Va. and close to George Washington's Birthplace. I was told they are sharks vertebras but I am doubtful. Can someone identify them? I'll post the other vertebrae in the next post.
  17. Best Teeth of the Month

    Hi everyone! I've had quite the month here in Wilmington, NC. After some recent dredging, I've been scouring the beach (often multiple times a day) for any good finds. As far as beach hunting goes, this is by far the most productive month I have ever had, with some of my all-time best teeth coming out of Wilmington. I'm really excited to share some of my finds with you guys. The teeth pictured are only the best ones found from April 20th to May 20th, 2018. There are many more not pictured that did not "make the cut". If anyone has information about any of my teeth or would like an alternate angle of a particular tooth, please reach out! Happy Hunting

  19. Shark teeth ID

    I have these shark tooth fossils which I purchased for about $5 in Florida. I tried my best to group them according to appearance, but I'm not sure how well I did. They all need IDs.
  20. awesom 11,3 Mb I just received a postcard from my retinae:"enjoying the Bahamas,won't be back anytime soon,you &*&(((()_+&@W" "And you may tell yourself :"This is not my beautiful fossil""
  21. Hey all, im posting this in hopes some of you shark folks may be able to help me out. I have a shark tooth in a concretion from the west coast. I have decided im going to prep this one myself and leave a backing of matrix on the ventral side of the tooth. So my question is, is it possible to tell the ventral/dorsal from what little is exposed already. This is probably a carcharodon sp. tooth but i really wont be sure until i am able to prep it. I have compared this tooth to some megs and white shark teeth i have in my collection and im kind of leaning in one direction already but i really don't know that much about shark teeth so i would be interested to hear other opinions. I took some photos and added A and B as to distinguish the sides. Any ideas or advice is much appreciated. Nick
  22. White sharks teeth fossils?

    Every now and then on the forum someone posts a cream colored meg, or some other type of white sharks tooth. I just thought it was cool and moved on, but after finding two white sharks teeth myself (one below) I started to wonder how this could be. I extremely doubt it’s the original enamel, though I’ve doubted true things before. Would this be because of a certain mineral? Perhaps plant acids, such as in lightning strikes? Just from wear? Are there multiple factors?
  23. Hey everyone, I was just wondering what exactly intermediate teeth were and also what the difference between symphyseal and parasymphyseal teeth is. The small fourth tooth in the upper jaw of Carcharias taurus is marked as an intermediate. Thanks for any help!

  25. Added three new teeth in recent times to my collection of exotic meg teeth, I'd like to share since there,s not to many images from these localities out there, the photos maybe in shabby quality because I pulled them directly from my Instagram page to save time. 1) This partial tip of a meg was found in the Chiba prefecture of Japan! Acquiring this, even just a fragment was a real pain in the butt as megs from Japan are extremely scare. 2) Even though its not a Meg of course but still being the closest ancestor, this 3.1inch chubutensis tooth was found at a land site in Lecce, Italy with gorgeous color! 3) This tooth measuring 4.1 inches came from new site in Bangkalan City, Java, Indonesia. A majority of the megs here were found with absolutely terrible preservation so this one is one of the best out of the bunch! A few more pics of these teeth can be found on their posts on my page at https://www.instagram.com/nyislandfossils/ if its ok to post this here.
