  1. I found this his big tiger shark tooth at a local rock shop today. The tag says Eocene but no location info is provided and the store worker had no idea. It looks modern, but the enamel has chipped back a bit as if fossilized. Was wondering what you guys thought? cheers!
  2. Pachygaleus lefevrei
  3. Nice fresh specimen.
  4. Hey guys, Just wanted to show my new addition to my small collection a 4.85 inch Meg tooth from Hawthorn Formation, Sth Carolina. I really like it because of its natural glossy dark grey color and I also upgraded to a larger tooth. Thanks for looking guys
  5. Hello Everyone, I've been working to fill this antique machinist's tool box with my shark tooth collection for a little over a year, and it's finally shaping up nicely. Most of the teeth and fossils are self-collected and most of them are from the area around Charleston, SC. Hopefully I'll need a larger cabinet a year from now. Thanks for having a look! The case itself - The broken/B-grade teeth- Misc. fossils (non-shark) - Carcharocles angustidens, Isurus hastalis, Isurus desori, Isurus retroflexus - Alopias and Parotodus - Hemipristis and Carcharodon carcharias - Larger angustidens & Carcharocles megalodon / Teeth from other locations- Pathologies, oddities, juvenile/posterior angustidens & megalodon - Large angustidens & megalodon -
  6. Last week I got the opportunity to go fossil hunting in an abandoned Lower Carboniferous/Mississippian marine limestone quarry near my home in Fife, Scotland. The quarry exploited a bed known as the Charlsetown Main Limestone. It is from this bed and the overlying beds of shale that I have collected the majority of my Lower Carboniferous marine shark and cartilaginous fish fossils from various sites across the Midland Valley of Scotland. I try to check the site as regularly as I can as new material is constantly being washed out of the spoil heaps, but the overall area where fossils can be collected is very small. I hadn't found anything worth keeping on the last few trips but on this occasion I found a nice near complete Cladodus mirabilis tooth on the first block of limestone I picked up, needless to say I was pretty chuffed! This tooth was found on the bank of a flooded section where the lapping water is eroding the side of a spoil heap and in the past Ive found two partial Cladodus striatus teeth here as well as lots of well preserved inverts like crinoids and brachiopods. Ive decided next time I go to take equipment for sieving the mud on the bank and bed of the pool for fossils, so hopefully by using this method I'll soon have lots more nice finds from this site to show! The flooded section with the Charlestown Main Limestone and shale layers above exposed (photo taken last summer):
  7. NSR is dry and footprints everywhere but I still had a great day. The Mosasaur Angular with shark feeding marks & possible shark tooth embedded is my favorite.
  8. This tooth was found in a Miocene area a while ago. I thought Mako at the time and didn't give it much more thought. I have recently seen some makos someone else has found over the last couple years and they don't seem to have the bulk of this this. This one is 2" long but a nice 1/2" thick. Any help with ID is appreciated.
  9. I picked up this paleocarcharodon tooth from the auction site a couple of weeks ago. It was misidentified as auriculatus and has no collection data at all, but was only $10 or so, so I bought it. Because of the faint serrations, it looks like an early paleocarcharodon to me, which is why I wanted it. There is some restoration to the root lobes, which is never ideal, but the blade and cusps have not been touched. My questions are; 1. Do you agree with my assessment that it is an early transitional paleocarcharodon? 2. It looks like a typical Moroccan tooth to me, which is certainly where it originated, but would anyone know if it is safe to presume more detailed data or is this tooth common from multiple localities? cheers!
  10. I've had this fossil keychain since I was a kid and I'm not sure exactly what species it belongs to. It's 1 1/2 inches long and wide it has serrations and the back is flat. Based on the size and shape I either believe it to be a really small megalodon tooth or a megalodon ancestor from the carcharodon's. But that's just my guess what do you guys think?
  11. In your opinion, what is the weirdest fossil vertebrate? I would like to see pictures! I will start out with the Helicoprion shark!
  12. Hello Everyone! I had the foresight to take my camera with me on my hunt yesterday. Before you ask - no, I didn't get a ground shot of the mastodon tooth. To be completely honest, I didn't know what it was until I got home...I probably wouldn't have even picked it up except that I noticed some symmetry. Anyway, I snapped a few shots of some decent shark teeth. Nothing too impressive, but steady finds all the same. enjoy - Here's a neat little whale tooth -
  13. I'm wondering if this is a small benedeni tooth and if not what is it? It's 1.2" long. cheers!
  14. I'm not sure what type of tooth this is, I found it in Venice, Florida. I've been thinking that it is a mako shark or extinct mako shark tooth, not exactly sure though
  15. Going through a bucket I brought home last night I found this nice little Ptychodus tooth. Looks like P. mammillaris?
  16. Spent a couple of hours at Post Oak Creek and boy was it a popular place to be today. There were families everywhere. Spent some time on my own before a guy showed me his piece of a tooth he was proud of and asked me if I had found any teeth there before. I asked him if he had been out to the creek before and he replied that he hadn't. I offered some help and before long I was surrounded by a couple of different families. I helped them find a few teeth to get them started for which they were all grateful. Found a few really nice Ptychodus and let them "find them" as well as a really nice Squalicorax that I let them find and keep. I hoped it would help me with the fossil gods but not so much. Didn't help the juju. Spent an hour and a half walking further up the creek hoping for some untouched ground but that was not to be had. Found a few small nice teeth and rest shards. Always just happy to be digging.
  17. This is a fragment of shark tooth (?) I collected yesterday. Hoping someone will recognize the unique texture and be able to associate it with a known taxon. This is from the Big Clifty Formation in Indiana (Mississippian: Chesterian). Ruler increments in photo are 0.5 mm.
  18. A new study led by the American Museum of Natural History (AMNH) provides the strongest evidence to date that sharks arose from a group of bony fishes called Acanthodii (‘spiny sharks’). Analyzing a well-preserved fossil of Doliodus problematicus, a sharklike fish that lived 400-397 million years ago (Devonian period), John Maisey and co-authors identified it as an important transitional species that points to sharks as ancanthodians’ living descendants. http://www.sci-news.com/paleontology/sharks-acanthodians-04706.html
  19. I found this shark tooth yesterday in the first chalk bench of the Fort Hays Member of the Niobrara approximately one foot off the contact of the Carlile Shale (my first keeper from the Niobrara). I was able to prepare it as best I could this morning and realized it doesn't have a root. This was my first matrix prep of a fossil and I'm pretty pleased with how it turned out. I was hoping someone could help me identify it. I think the photos look at the lingual side of the tooth. Also - since it's imbedded in chalk, it is beginning to separate from the matrix. Does anyone have suggestions for helping affix it to the matrix? I would superglue it but don't want the glue to affect the overall appearance of the enamel. Thanks!
  20. My wife and I are traveling north from FL to PA on April 3. Would anyone be willing to point us to a nice locality is SC? We will only have one day (Monday April 3) so no vacuuming of the site will occur! I can reciprocate with access to the Ernst Quarry in California. PM or email to tngray <at> nautiloid.net
  21. So with much reading of the helpful info here on TFF, I was able to put some of the knowledge into practice and finally found a whole megladon! Thank all you contributors very much, (esp ShellSeeker & Sacha for your reports & photos). Myakka is a bit closer to me than Peace River but I can see several reasons why this river is not as inviting. Much more wild life (3 Snakes & 1 gator), the river has drastic depth transitions (knee deep to over your head in 6"), it is usually turbid (tidal effects?). Much of the fossil material has become embedded in the limestone so they aren't as pristine. Below is about 6 hours total effort (about 3 hours heavy digging). Thank you TFF! Calvin
  22. I took a long 8 - 10 mile hike at NSR. The weather was beautiful and wildlife abundant. I saw hogs, deer, beaver, hawks, ducks and geese among others. I picked up a nice variety of fossils. I really like the Xiphactinus jaw with replacement tooth showing. I sat down to take a break and found 4 shark teeth in one area. The little fossilized turtle scute is also cool.
  23. Lower Lutetian ("glauconie grossière"), possibly reworked.
