  1. Location: Missouri Geological map states that the area is Pennsylvanian Found in a rock pile left by construction workers that blasted out the rock. I have found a few teeth in the area such as Petlodus, Orodus, and a few others. Previously posted on r/FossilID they gave some good insight, but I am curious to what other enthusiast think. I know its some sort of Holocephalan but I was told it could be something from Eugeneodontida I have also found another fossil near it, but i did not want to assume they were from the same shark, or if it was from a wild more modern animal Size reference, with right side having flash on while the left does not.
  2. Hey guys! It’s been a while since I’ve been active, it’s good to be back My roommate and I took a trip out to Oglesby, IL today for his first fossil hunt! We found some nice brachiopods, but the absolute winner for me were two associated shark teeth (I think). It might be a cladodont, but sharks are really out of my spectrum, so if anyone could help I’d be quite appreciative!

  3. What is this?

    I was digging in the sand and found this in Avalon, New Jersey. It looks like half of a shark vertebrae. But I’m not really sure! If anyone can provide any identification and further info I would really appreciate it!
  4. Hi all, I'm hoping some of the resident experts here can help confirm or correct my IDs of the three fossil shark teeth and what I believe is a cetacean lumbar vert shown in the pictures below. I found these recently on a beach along the Calvert Cliffs in Maryland (Miocene exposure). Thanks for your help! For the shark teeth, I believe the the two on the left are both Carcharodon hastalis (though am more confident in my ID for #1) while the one on the right is possibly Isurus oxyrinchus though may also be Carcharias sp. All three have worn roots so I realize that may complicate the IDs. See pictures further below for scale bars and labial and side views of these. From pictures online, I believe this is a cetacean lumbar vertebra. The "bumpy" surface in the two lefthand photos also signifies that the epiphysis is missing, and thus this came from a juvenile, correct? Is it possible to further identify this as from a particular species or genus? Thanks in advance for your help!
  5. I was in big brook early Saturday. After the storm Friday the water was higher faster and murkier than usual. I was walking down stream trying avoid stepping on and tripping in some of the big stones. I avoided a roundish one but noticed some lines on it. Looked again and the lines were not just random. It was 3-6 inches below the waterline and I bent over to look at it more closely. It was a turtle shell. It was bigger than my pan it looked to be complete. Omg! I was so excited. Fossil or modern? I figured modern but was just fine. My concern was that it would have innerds att attached but ok I would clean whatever needed. So I went to gently tip it over to look with my trowel and it MOVED!!! Upstream!!! Touched it again and it moved against the current a bit faster. It had never dawned on me that it was alive. And so I went on to the usual big brook finds and the memory of my greatest find of my lifetime ... almost
  6. I kayaked for five miles on a day with a heat index of 108 degs and found some killer stuff. The Paleo Dalton point made my day. Rare to find mosasaur in this creek but I still managed to find a few verts. The big nautilus was beat up but looks good in my rock garden. The old bottle is a duraglas bottle from 1953.
  7. Carcharodon hastalis

    Hi everyone, I have here a tooth being sold. The merchant identifies it as Carcharodon hastalis. Based on confirmed photos of Carcharodon hastalis, I have many doubts. My main reasoning is that the angle between the start of the root and the rest of the tooth seems far too steep. Carcharodon hastalis, to me, seems to have rather straight edges; this one appears way too curved. This is why I believe the merchant may have misidentified their tooth. It's 19 mm long, and supposedly found in Chile. I'd appreciate any confirmation, and apologies as these are the only two photos provided by the merchant.
  8. Hi. Along with most of the fossils in my collection, this tooth was also found on the beach on the north end of Amelia Island, Florida. I am not having any luck in identifying the shark.
  9. Carcharodon hubbellii?

    Trying to get a ID. I was wondering if this was a Carcharodon hubbellii? Or what species it maybe. Thanks in advance
  10. Hey everyone, I am new to the forum, but have been searching for and collecting shark teeth for years. I found this tooth earlier today, but didn’t know for sure what kind of shark it was. My first thought was a Great White but it is smaller than some of my other great white teeth I have found or seen. It does have serrated edges. Any help is appreciated and thanks in advance!
  11. 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!
  12. Hi all, I have a shark fossil from Hakel, Lebanon that is unidentified I presume it is of the Scyliorhinus genus. I was hoping someone would be able to tell me what species it is. It measures approximately 13 inches Thank you
  13. Carcharodon Plicatilis?

    I have here a tooth from Charleston, SC, a river find. I've narrowed it down to a white shark, and based on this guide I'm torn between Carcharodon Plicatilis and Carcharodon Carcharias. I'm leaning towards the former. Could anyone please provide confirmation?
  14. Ramenessin brook trips

    Hi all, about two months ago I asked about ramenessin or big brook being better. Here are my finds from about six two hour hunts at ramenessin brook, and searching gravel I took home, it’s more fun searching there but bringing some home and searching through it is better than not looking at all. The best finds are a couple of 1-1.5 inch shark teeth, a small croc tooth, a rat fish jaw, a small shark vert, a very water worn sawfish tooth, a burrow with invert fecal pellets, two ammonite fragments, shell casts, a small shark tooth I believe is a nice angel shark tooth, a drum fish tooth, an Enchodus tooth with jaw attached, and some shark teeth with really nice colors! If anyone could confirm the angel shark tooth is really an angel shark tooth @The Jersey Devil @Trevor @hokietech96 @frankh8147 @Darktoothit would be greatly appreciated!
  15. Otodus tooth or something else?

  16. Last weekend I decided to take a short drive to Vermilion County, IL and get outside for a little bit. I haven’t been able to do any fossil hunting since COVID-19 reached our shores, so I had a few iffy sites less than 40 minutes from home in mind as I was driving. The first two proved fruitless, but I decided on a whim to take a new road over a local river in hopes of finding some exposures there. The river was running high with verdant growth all around and dragon and damselflies filling the air. As I looked down from the bridge I saw sandy shore, concrete bridge abutment, and then a small section with some intriguing rocks scattered along the river’s edge. Once I made my way down to river level, I found that the black rocks visible above were pieces of black shale and coal. I was excited! I had been thinking of black shale since collecting some on an ESCONI trip last year and reading @connorp’s posts about black shale finds. This shale was much more fragile and bedded than the Mecca Quarry Shale I found last year, so I was able to split it easily by hand. I was too excited, so I forgot to take any in situ photos (I took the ones above on my way back to the car). Before too long, I spotted the unmistakeable shape of a dermal spine from the iconic black shale chondrichthyan fauna Listracanthus hystrix- a strange shark relative covered in spiny denticles. I spent about 30 minutes searching this small exposure and turned up several more Listracanthus, the inarticulate brachiopods Lingula and Orbiculoidea, fish scales, and some mysterious spine fossils. Unfortunately, almost everything was tiny (less than 1 cm) and I don’t have a macro lens for my phone yet, so photos of most of them will have to wait. Here is everything I kept after trimming the matrix down: I will share some more pics of the best Listracanthus in my next post.
  17. NJ shark tooth

    Hi, I found this tooth at ram brook and was wondering what type of tooth it is, it doesn’t appear to have cusps, which is making me wonder what type of tooth it is. It’s about .75 of an inch.
  18. Unidentified shark tooth

    Hi all, I bought this tooth last year on a road trip, and was wondering what what type of tooth it is? It is about one inch long. I don’t know any other details though. But I was if anyone could still identify it for me? TIA
  19. Well, I have just found out that a prehistoric shark I have always been fascinated with can actually be found in my home state! Unfortunately....I no longer live there! I would love to get my hands on one just to bridge this nostalgia with a piece from home and am happy to work out a trade or the like as necessary. So if anyone has a Stethacanthus shark tooth from Oklahoma and they are interested in trading, please message me! I unfortunately have hardly anything in the way of fossil shark material, but I might have something else that could be of interest. If there's any other obscure shark teeth from Oklahoma I don't know of (besides Barbclabornia and Orthacanthus), I'd be interested to learn more on them as well Always learning new things!
  20. Helicoprion Shark Fossil?

    Good afternoon, I would like to start off with saying that I know very little about fossils and Geology so please excuse me if I make any errors or misstatements. Recently I purchased approximately 10 cubic yards of rock from a local business to use for landscaping around my property. The business has claimed that the rocks they sold me were excavated from in or near the banks of the Snake River in Southern Idaho. I unfortunately do not have a more exact location but I would be willing to possibly follow up with the business if more information is needed. With the help of some friends we were able to determine that scattered throughout the 10 yards of rock I received were Agates, Jasper, Opal, Amber, Star Garnets, and small fish and crustacean fossils with some even appearing to be in a preserved state encased in a soft yellow translucent amber. Knowing some of the types of rocks I received, the general location of excavation, and a brief history of rare fossils that are found within Idaho I was stunned when I came across the specimen pictured below. Most notably the spiral tooth-like feature is what drew me to this rock and made me take a closer look. There are very distinctive features that appear to be eye holes, nostrils, gills and of course the famous spiral tooth pattern. The internal structure looking through the eye is a completely opaque white substance that resembles a mix of opal, amber, and other silica material. The silica based specimen appears to be sitting on top of a hard rock stone. Sunk into the very bottom of this stone is a 2nd spiraling tooth-like feature which I only guess could be the other set of teeth. After coming across this rock and with the little stated knowledge that I have on these subjects I took to the internet to attempt to research Helicoprion fossils and in general shark fossils. As many of you are probably already aware besides teeth it is very rare to find any fossilized portion of a shark of any species let alone a possible intact skull from one of the rarest sharks out there. The overall size of the specimen is also a little concerning as my understanding is that the Helicoprion shark was a rather large shark and was likely somewhere between 3-5 meters at full growth. After doing the research on whats out there and based off of what I already know I still remain rather skeptical that this is what I'm claiming it to be but at the same time remain hopeful that this is a fossil of some sort as I am having trouble coming up with an explanation for the content that this rock is made of among others in the rock pile and for a reasonable natural explanation for spiraling patterns. This is 1 of 3 rocks that I've found thus far with spiraling teeth-like features. The other 2 are made of similar material, resemble some similar structures, and share distinctive features other than the spiral such as eye holes, nostrils, jaw lines, and ect. The major difference between the 3 is the specimen that is pictured here is larger, more intact, and displays the most features. I appreciate any feedback that I can get because of the pandemic college campuses are closed and it has made it hard to get in contact with people who could possibly help me. I would like to have as much knowledge on what this possibly is before jumping in the car and driving to the nearest Natural History Museum which is over 3 hours away from me. I would hate to do something like that if this is only just a "cool" rock. I have many more pictures if needed displaying all of the features mentioned and many more as well as pictures of other specimen found in the same rock pile just let me know if they are needed or wanted and I can message them or make another post with them.
  21. Hello everyone, Curious if anyone knows the difference between Xenacanthus and Orthacanthus shark teeth? Particularly as it concerns shark teeth from the Permian site in Waurika, Oklahoma? Have quite a few shark teeth from there and am unsure how to determine which is which. There's also Barbclabornia, to complicate matters! Any help would be appreciated (and yes, I have seen the rhynie chert website on them, but it doesn't show/tell the difference between the three kinds)
  22. NJ shark tooth

    Hi all, I found this tooth in a Monmouth County stream and was wondering what type of shark it is? I would have thought cretalamna appendiculata, but it has bourlette, and I don’t know any shark teeth in the navesink formation that have bourlette. It is about 3/5 of an inch. @The Jersey Devil @Trevor @Darktooth. TIA
  23. mystery shark jaw

    Hey there! I need some help identifying this shark jaw that I received as a gift a few years ago. All I know about it is that it came from Isla Mujeres, Mexico. Its about 23 centimeters in width and about 8 centimeters from the top of the mouth to the bottom, my apologies for how gritty the pictures are, my phone camera is not the best.
  24. These are mostly South Carolina River finds, with a couple of Moroccan specimens mixed in. The Megalodon teeth are all natural, ranging from 3” to the 4” range. The shark vertebra go up to about 3.5” in diameter. I have more elsewhere as well. And more Megalodon teeth. LOOKING FOR: I am open to all offers. I am especially interested in matrix pieces of different kinds, unprepared fish, but again I am very open to all sorts of offers.
  25. Bite marked bone?

    I found this in Polk county, Florida a couple months ago and while looking through bones recently I found a couple things I hadn’t noticed and one of them was this small bone fragment that I think has a bite mark in it. It is almost exactly 3/4 inches.
