  1. I've not had a chance to post my finds here in a while but over the past few months I've found some new specimens of Lower Carboniferous/Mississippian marine shark teeth I wanted to share! These were collected at various sites in the Midland Valley of Scotland from the Blackhall Limestone, an extensive formation with interesting variations in fauna at each different locality. Ctenoptychius sp. Anterior tooth in lingual view, 6mmx7mm.
  2. Hello, here I am again with a second tooth that a friend of mine bought few days ago. It's a quite small one but, for its price, it was a good purchase. The seller described it as belonging to a juvenile Carcharocles Megalodon (Miocene, Florida) but there're some doubts about that. What is your opinion on it? Does it belong to a Carcharocles Megalodon or to another specie (such as a Carcharhinus sp.)? Thanks for all the suggestions. (that's the only photo I have, if another one is needed I'll ask for it)
  3. Hello everyone, I've had an idea for a while now to write and illustrate a guide on the fossil shark species of SC and how to find their remains. I really am not sure where I would like to begin, but my brainstorming process apparently involves a certain amount of doodling. These pages represent studies for how I might like certain parts of the guide to look, though all text will be typed in the final product. I am looking for any feedback - critique of the artwork, topics you'd like to see covered, additional information, etc., etc. enjoy! Here's a page that started for a mock-up for the specific species Hemipristis serra. I also drew a representation of Isurus desori on the bottom... A page dedicated to Carcharocles/Otodus megalodon (as I imagine him) And a portion of a simple tooth guide (not really sure how to incorporate this yet) - And thats most of what I've got so far. What do ya'll think?
  4. What is that thing?

    Good evening TFF friends. I have found the following fossil few time ago in amakusa, japan. It is a cretaceous formation (santonian) called himenoura formation. It is a small round fossil of only 2 to 3mm. It has a conical shape with kind of regular growth circle. On the picture you cannot see it but it is covered with enamel. It is kind of common fossil in the part of the formation where cretalamna' s tooth are abundant. Could it be a kind of dermal dentical or is it something else? Thank you very much for your help. David From above. There is still some matrix on the upper part but the fossil is perfectly round.
  5. Hi I was wondering if anyone could help me with the location of this Meg tooth. I know color alone prob won’t give me an exact location but I was hoping someone would be able to narrow it down to a couple locations. Also was $47 a good deal for this tooth? I know the forum doesn’t allow appraisals but I’m not sure if this question is considered a appraisal. If so then please ignore this part. Thanks for any help.
  6. Hi, I need ID help with six shark teeth found in Morocco. I'm thinking the two in the middle are Otodus, but I'm no expert.
  7. Extraordinary Common Teeth

    Hey guys, I've been off the radar for awhile .. work you know .. been working on Siggraph for those of you who are familiar with software development. Just wanted to start a new topic here .. This one is right at 3.00" - 7.62cm C. carcharias Bahia Inglesa Formation South of Caldera Provincia Copiapo III Regio de Atacama Chile
  8. Today's Massive Desori Mako!

    Hello Everyone! It's been a minute since I've had the pleasure of finding any fossils worth posting here, but I was lucky enough today to squeeze in a couple hours of hunting. I noticed several sets of footprints around my usual hunting site - others had picked through the material recently. Undeterred, I made my way along the river visually scouring every square inch of exposed grey-brown Oligocene formation and gravel. Im glad I stuck with it because I was rewarded with several nice (albeit small) teeth from the extinct mega-tooth white shark, Carcharocles angustidens as well as a slew of smaller teeth. Then, just as I was ready to start hiking back to the car, I noticed the root of a VERY large mako tooth sticking out of the ground. When I pulled it up I was reminded of the sword in the stone..it just kept going and going. At a little over 2.8" it's one of the largest Isurus desori teeth I've ever personally seen. It's in great condition with exceptional color to boot. Thanks for taking a look and as always... Happy hunting! SOSC
  9. Here's a sample of my favorite teeth and artifacts. Most are personal finds from the Northeast Texas area.
  10. Mystery Petalodont

    I found this little tooth a few months ago in the Coal Measures (Westphalian A) of Scotland in a fresh/brackish water deposit and thought it might be a Janassa sp. of some sort but now I'm not so sure, the only other Petalodont genus's I'm aware of in the British Coal Measures are Ageleodus and Ctenoptychius but they both have multicuspid crowns, the tooth is in labial view and is 11mm across. Any thoughts would be greatly appreciated!
  11. Shark tooth from Florida

    Here I am with a new fossil. It's nothing special but where I live sellers usually have only shark teeth from Morocco / North Africa. I'm not an expert in the "shark teeth identification" field and I can only make hypothesis about the specie it belonged to. Suggestions? What are the diagnostic characters that can be observed in it?
  12. I was in a local Barnes & Noble last week and was happily shocked to see that a second edition of "Oceans of Kansas" had been released (came out in September). The first one (Everhart, 2006) was a great surprise in its own right. If it had been just a faunal review of the various layers of the Niobrara Chalk, it would have been interesting enough but it covered even more oceans than that. A seaway covered much of Kansas over much of the Cretaceous but it wasn't the same cast of characters from beginning to end. Various organisms evolved, co-existed, and disappeared across that time and the book is an excellent guide to the fossils found and studied up to the mid-2000's. The second edition looks to be a must-have as well. http://www.iupress.indiana.edu/product_info.php?products_id=808653 It's the only thing on my list to Santa. Jess
  13. Shark tooth ID

    My friend has always had this tooth in his collection that he found in gravel that was in a garden in Paris, it is obviously a shark tooth but we have no clue as to what species it is. And it would be helpful if someone could tell me what species of prehistoric shark it is.
  14. I was thinking that this is a Cow Shark para-symphyseal, but upon taking the pictures and zooming in, I am not as sure as I would like to be. Please refer to the following three closeups. The slant length is about 5.57mm. -Bill H.
  15. I found this yesterday, November 26, down at Venice Beach, FL near the fishing Pier, along with an assortment of shark's teeth, coral and other interesting things. It looks like a tooth to me but I didn't think it was a shark tooth. Does anyone know what it is from? Thanks in advance! I'll have to post separate posts for different angles; I guess my files are large.
  16. I have been finding a lot of inclusions in a batch of coprolites from the Smoky Hill Chalk that assumed were bits of cartilage. One of the newer specimens from that batch had a piece of the material in question on the surface; enabling me to view it from the side. They look like little teeth, so now I don't know what I have. I have one other specimen that has a couple of the little tooth-like structures intact (one that I posted a while back that has possible Ptychodus tooth fragments). Is this skin with denticles, cartilage, a skull part or some sort of tooth plate? As always, any help is greatly appreciated.
  17. North Texas Creek Hunts

    I managed to get in 3 hunts on my 14 days off from offshore this time. I found more artifacts than fossils but I did manage to find a nice Mosasaur vert, shark teeth and a really old coke bottle. This is a mix from Post Oak Creek and one more creek that I hunt. I gave away all the teeth except for the perfect ones to my buddy since it was his first time ever hunting.
  18. Need to ID this Tooth

    Found this tooth in Bakersfield, in the Round Mountain Silt formation on Nov 12, 2017. From looking at the diagrams on this site, I think it could be megamouth shark tooth. But I am not sure, since I think that is not a tooth found in that formation. Any comments or ideas are appreciated.
  19. Gray shark tooth

    A tiny tooth of an Abdounia minutissima. Bought from an old collection. The site at which it was collected, the Egem quarry, is now unfortunately closed. I have had some confusion to the family: on fossilworks.org, in the order Carcharhinoformes, it says that Abdounia is a subtaxa, while it's already a genus. It goes straight from Order to Genus, and it doesn't cite any family. If anyone knows more about this, please feel free to send me a PM and I will edit the post.

  23. Moving to Tampa!!!

    My wife just got a job in Tampa so we're headed South from Connecticut!! I can't wait!!! Any fossiholics there and could maybe show me around when I get there? I've been to a couple beaches down there and found a bunch of sharks teeth but I want to go bigger. I want to get scuba cert and go exploring. I can't wait!!
  24. I found this tooth a few days ago, while walking around a limestone quarry in Cardenas, Cuba. I was digging through discarded pieces of limestone blocks, threw a large piece and the stone split showing me this beautiful tooth. It measures 5.015". This tooth is my nicest personal find and one of the nicest teeth I have seen come out of Cuba. I usually buy my teeth and consider myself super lucky to find this myself.
