I have been using this website to help educate myself and identify theses teeth. I believe all teeth on the right of the penny are the sameness; Lemon Shark. I also believe that all the teeth are the same to the left of the penny. My initial thought was Copper Shark. After going through this website I was thinking Thresher Shark. Any help or confirmation with thes would be much appreciated. This is the link https://www.floridamuseum.ufl.edu/discover-fish/sharks/fossil/shark-tooth-id-guide/#q23

If I had to guess on some of these the top 2 on the left are lemon, far right is a hemi, and bottom left is a hammerhead not sure about that or any of the others any help would be much appreciated

Hi. Can anyone pony me in the direction on what type of shark teeth these are. That seem to be all the same type. Thanks for any feedback. Mark

Hi. Me again. I feel like I post something everyday asking for help. I really have learned so much from everyone here the past month. So a big thank you. So I believe based on research and past post that the first group of teeth are bull shark because the location of the nutrient pore on the lingual side is below the bulge in the root. The second picture I believe is also carcharhinus but not bull because instead of a nutrient pore on the lingual side there is a transverse groove. So that leads me to the question what type of carcharhinus has a transverse groove? I hope on the right path in my thinking. Boy I hope so or this post will be embarrassing. Haha. Thank as always for any feedback! Mark

My friend joined me for a weekend of black water diving. She found a couple massive heart-breaker megalodon teeth her very fist time! Perfect conditions all weekend long made it a great time on the water.

Found at a site in Charleston. Would love help to ID

Hi are these bull shark or dusky shark teeth. How in the world to you tell the difference? Thanks for any feedback!

I believe these are all Hemi’s not confident about the top row far right one. Any feedback would be much appreciated. Thanks!!

Holly smoke! now I know why I should have listened to my teachers when I was in school. I am so far over my head in this fossil and rock thing that my eyes hurt thinking about it. I do mostly river hunting here in VA. and until I came across this site my life was normal, now I'm not sure about anything. It seems now I have more questions than answers. Walking the banks of the James river looking for arrowheads I always seem to come home with more different looking rocks than I do arrowheads. Picking up rocks that look like they may be arrowheads but are not got me to wondering. One question is, is there a fossil hunting for dummies thingy anywhere? One of my sons likes to look for shark teeth and I go with him some times to walk the river banks. One of my questions is, do all real shark teeth look like the pretty little black and grey colored things he always brings back or could a tooth be completely turned to stone like river rock you see along the bank of a stream. Also is it possible to find a tooth in a sediment layer, like so called mud rock that is shaped exactly like those pretty ones that everybody else finds but is just a blob of the same material that its encased in? I was digging a couple buckets of of that sediment layer to use for planting material when I noticed something strange looking in the soil. It was getting dark and we had to leave to get back. A day or two later when I dumped out one of the buckets I noticed bone fragments and what looked to be parts of some kind of vertebrae. Out of the three buckets I collected there was over a bucket full of these bone like pieces and a lot of pieces that had the shape of teeth but were just a mass of the grey sediment looking material. Hopefully I will get to go back to the site later to find out what I have destroyed and to see what else may be there.......but more carefully this time I promise. I'm going to try and get some pics of some of the things but my camera battery is dead and I have to get a new one. When I do post pictures it will be in the fossil ID page.

Found these on the NJ beach this summer. Just looking for confirmation that I ID them correctly. Thank you in advance for any feedback.

I have always loved history and old things from the past. I have been a Civil War relic hunter on and off for 40 years or so. I don't get to do that much anymore because pretty much all the land I used to hunt has been bought up by the Government or the Civil War preservation people and you can no longer hunt there. A couple of my old hunting buddies got me into Native American point hunting along the banks of the James and Pamunkey rivers and for awhile that was fun but all they wanted to do was hunt the same spot over and over looking for that perfect point. We would hit a bank and everybody would take off walking the shore line and most of the time when they got back I was still right in the same spot scratching along the bank with a bag full of rocks, not many points but a lot of rocks that looked like arrowheads, to me anyway. Every now and then they would come back with that perfect point and the bragging would begin and they would always give me a hard time about my bag full of rocks. After awhile I had collected a pretty good sized rock pile and decided to make me a rock garden in front of my shop. While moving all those rocks to their final home I began to notice some strange markings on some of them and after looking closer I noticed how much some of the sharper pointed rocks looked like teeth from some kind of animal or fish. I had found shark teeth before walking the banks of creeks and streams but most were tiny little things, some of these I was finding were much larger and looked like regular rock rather than the normal looking shark teeth we more commonly found. When I would try to explain my thoughts they would laugh and just tell me to, 'drink another beer, and you will think more clearly in the morning'. LOL I then decided I'd find me a new hobby but ever time I walked by that rock garden I would always see something different than I had saw the last time I looked. One day on an outing with my oldest son I dug up this rock that really looked weird it was covered with mud but I could tell there was something different about it so I threw it in my bucket. Yeah, I'll admit I am hooked as I no longer carry that little bag tied to my belt loop I now carry along a couple 5 gallon buckets. Besides, that little bag would get so heavy it was hard for me to keep my pants up. Anyway, when I got home and dumped out my buckets on the ground so I could wash off some of the mud and as soon as I sprayed that one funny looking rock with the hose this shape of what looked like a snake popped out like a neon sign. Once clean I could tell that the rock was a sedimentary type rock by the layers that it showed. There were some dark layers and in-between were some white layers. Anyway, the top of the rock that had the white rocks on it looked like it had been carved away to make the shape of a snake. Boy!! I really got laughed at when I let the boys know what I thought I had found. They decided there was no amount of beer that would ever make me normal. In my limited knowledge about fossils I knew that when a fossil forms only the bone or more solid parts of animal would fossilize and become rock so I knew, or I thought I knew that the whole snake would not be presented the way this one was. So I decided that some poor Indian one day stumbled onto this rock and a light bulb went off in his head and he said to himself, "you know Tonto, you haven't given the little lady back at the Tee Pee a present in a long time. Maybe I'll sketch up a picture of a snake on this rock and give it to her for her birthday. Then she can replace that awful looking picture of her mother she has hanging on the Tee Pee wall. Old Tonto was always thinking of ways to keep the peace back at camp. Sadly, he probably should have been paying more attention to his surroundings cause along came a big ol bear and he jumped out of the woods just as Tonto was putting the finishing touches on his masterpiece and ate him in one big bite. Thankfully, the bear spit out that rock right there on the edge of the bank before he headed off back to high country. I'm going to post a pic of this rock for you guys to take a look at and hopefully someone can tell me if my thoughts are anywhere near something that could be possible.

Other things I found today at Big Brook besides the bones I posted

Hi. Found these this summer on the beach in NJ. Have no idea what they are. Any help will be much appreciated! Mark

Sharktooth Hill Trip Report Part 1 – building the sifting table Hi everyone, After my first trip to Sharktooth Hill in June, I was hooked. I immediately started making plans to return and, this time I’d come better prepared. This forum has provided an amazing source of ideas and helpful people and inspired me to build a sifting table for my next trip to STH. A huge thanks to those who have helped me by answering questions, providing pictures and ideas, and helping me troubleshoot. I gathered as much info as I could and then tried to combine all the best ideas into one contraption to fit my needs. I’m excited to try this beast out next week! It’s big! The screen is 37.5” x 21” and the table stands about 4 feet tall but I will lower it if the height proves too high to load easily. I don’t want to sacrifice “wobbly-ness” though, because I’m hoping that’s going to do a lot of the sifting work for me. Plus, my son and I are 6’5” and 6’4” so a tall table should be ok. I used SCH 40 PVC and the 2 rectangular bases are glued while the 4 legs are removable to allow for compact storage/transport. In limited testing everything stayed together but I’ll bring some PVC glue with me in case I need to solidify it in the field. I'll also bring my PVC cutter for “disassembly” for the way home if need be. The bottom tier is ¼” mesh and has 6 “T” brackets to make sure it stays on top of the PVC frame. I bolted on a handle to allow it to be shaken one- or two-handed. There are no pointy parts on the inside (trying to avoid bleeding as much as I did on my last visit to STH). The top tier is ½” mesh and sits inside the bottom tier. Corner braces in the bottom tier (see above) allow the upper tier to sit low enough that it won’t dislodge but high enough that the contents can move freely across the bottom mesh. Initially I was disappointed that the large size and my inability to “tighten” that mesh caused it to sag noticeably once it was loaded up with soil. I remedied this with the addition of an adjustable bracket along the midpoint. But then when I put the top tier inside the bottom tier I realized I’d created a teeter-totter (doh!) and had to chisel out a groove on each side to allow it to fit in there. I’m very excited to go give it a try and I hope you all find this pre-trip report interesting. I’m happy to answer any questions and/or accept suggestions for improvement. And thanks again to all the helpful people on this forum whose previous pictures, design notes, and conversations encouraged me to attempt this (and make this post). I’ll send a follow up trip report after I get home. Cheers!

I’m pretty sure this report is going to get pretty wordy but I hope you all enjoy reading it! A few weeks ago a friend and I made plans to head down to Manasota Key for a day of fossil hunting on the beach. I left my house just before 7 AM and drove down to her house in Tampa. After transferring my things into her car we left her house just after 8 AM. We took I75 south until Venice Beach at which point we started driving on smaller roads. The plan was to check out any housing developments under construction or other construction sites we came across that weren’t posted. At the first housing development we stopped at there was a mix of completed houses, ones in the process of being built, and empty lots without a single no trespassing sign in site. We drove around the community a bit looking for a place to stop and ended up hunting around the edges of a retention pond. We didn’t find much beyond a few small shark teeth and bone fragments. After about 15 minutes we got back into the car to look for another spot. We could see an area that was still in the freshly bulldozed stage and start driving around trying to find the best way to get over to it. We found a spot in a cul-de-sac but there was one of those portable trailers that are used as offices for construction crews sitting there that made us a little nervous even though it looked to be unoccupied so we moved on to see if we could find a different access point. While we were driving around we came across an empty lot with lots of exposed piles of dirt and bits of rock so we stopped to poke around. That turned out to be a much more productive site the then first one although it was also a lot more muddy! While we were exploring it and dropping small shark teeth, turtle shell, and bits of bone another car pulled up near ours. Needless to say we got a bit nervous thinking it was someone official coming to tell us to leave. It turned out to be one of the contract workers that sprayed for insects and he stopped to see what we were doing. Turns out he had just started fossil hunting himself and he stopped just to talk about fossils! After he left we continued looking around and trying not to get too muddy although at one point I did sink down into the mud to my ankles and ended up falling onto my knees. Our best finds for that site was the large section of modern soft shell turtle shell my friend found and a dolphin ear bone I found. After a while we got back into the car to continue looking for an access point to the bulldozed area without success. Finally we headed back to the cul-de-sac and just try from that point. Unfortunately by the time we got there it was starting to rain so I put on a rain coat and walked out a little ways to see if was even possible to get over to the large piles we could see in the distance while my friend waited in the car. By this time the rain had changed from falling gently into a downpour and ground was becoming a quagmire. I could see that it was possible to get the piles but to do so we would have to go down a steep bank and across a construction rode that was rapidly turning into a muddy swamp. After getting back to the car we decided it just wasn’t feasible to get to the piles at that time and headed off to find lunch. One our way to a local restaurant we passed a shopping center under construction and decided to come back to explore it after we ate. Once we had finished eating the rain was down to a drizzle so we headed back to the shopping center construction site. Once we got there though we realized there were quite a few people working on the site and didn’t feel comfortable stopping. So we drove through the parking lot and stopped at the entrance to a side road. As we sat there discussing where to go next a dump truck passed us heading out to the main road while a second one headed in the opposite direction. We rather quickly decided to follow the second truck beyond the shopping center and into what looked like some type of complex or housing development that was in the process of being worked on. The section we were in had plenty of small trees and there wasn’t any bulldozed area but we figured that the truck was likely to lead us to a section we could look for fossils in. We followed the truck as far as we could but they it joined another truck in driving back into a section that wasn’t accessible to us. In disappointment we poked around the gravel road a little before turning around to finally go to the beach. As we pulled up to a stop sign at a two way road that would lead us back to the main highway we just happened to look off into the distance and spotted something that made us very excited, very quickly. Not too far down the road we could see the top of what looked to be an immense pile of limestone rubble and dirt towering over the areas short trees. We were quick to drive towards it and discovered the truly huge pile sitting in an empty lot surrounded by overgrown vegetation right off the main road. And there wasn’t a single no trespassing sign to be seen! We were so excited to start exploring that all we grabbed as we got out of the car were our buckets and hats before heading straight for the pile, completely forgetting about things like water bottles, sunscreen, or phones. The empty area leading up to the pile was littered with shells, bits of worn bone, and small sharks teeth. And the closer to the pile we got the bigger the teeth got! We rather quickly split up to search different areas. I tend to be a more methodical searcher than her so I move much slower while she is able to cover much more ground. I hadn’t managed to get too far down one side of the pile before I came across the biggest Mako tooth I’ve ever found and the color of it was fantastic. It quickly was put into the plastic container that I always carry in my bucket to keep my best finds separate from any large rocks or bone chunks I pick up. After that I keep wandering around and end up making my way over to a line of smaller piles were I find some nice sting ray barbs and a broken sea urchin spine. No while I’m collecting the nicer fossils for myself I’m also picking up all kinds of broken bits of bone for my parents to use in a sidewalk mosaic project that are planning for this fall. I get nearly to the end of the pile when I spot what I think is either a worn bit of bone or shell casting mostly buried in the dirt. But when I start pulling it out I realized that I had just found my first intact, decently sized Megalodon tooth! At this point I can’t start grinning while yelling for my friend and holding the tooth in the air for her to see! It is shortly after this point that I began to realize what a mistake it was to leave the car without a bottle of water as I was starting to feel rather ill. The two of us decided to retreat to the car and sit in the air condition for a while, drinking water and comparing our finds. About 15 minutes later we couldn’t resist returning to the piles to look for more fossils although this time we remember to grab both fresh water bottles and our phones. We still forgot the sunscreen though! Even though we searched around for about another hour and found more smaller shark teeth neither of us made any other big finds. At shortly after 5 we decided to call it a day and start the long drive home. We never did make it to the beach but it was fun and productive day. Because I forgot my phone in the car most of the day the only picture I took of any of the sites was of a strange looking plant I came across towards the end of the day. Below are pictures of my finds after I cleaned them up. It will probably take several posts to share them all.

Hi. I posted these two teeth yesterday but the picture was horrible. Any thoughts on what they are. I think one is a Mako. Any feedback is much appreciated. Thanks. Mark

Hi. First I would like to apologize in advance if I am stepping out of bounds with this ID request. Feel free to tell me if this is not appropriate. I am just really getting into this and trying to separate my collection of 800+ teeth by species. I think I have handle on the different types of tiger shark teeth but now I need help with these so I can get pointed in the right direction. Thank you so much in advance for any feedback and please tell me to go pound sand if this is a crazy pic. Mark

Hi! My name is Michelle Huddleston. I live in Holly Springs, North Carolina. My husband and I have been collecting shark teeth for the past 9 years. We have a little over 10,000 shark teeth which most are small. These were collected at Myrtle Beach, SC. We want to up the game and start doing river hunting and quarry digging so we can find bigger teeth or unique colors. I did some research over the weekend. Looks like Summerville, SC is a hot spot but we don't know where to go. I found some quarries we can go to so that is set up. Anyone have a place we can go find megalodon teeth at? That is the one tooth we don't have yet. Thanks! I look forward to being in this group.

Here are two anterior teeth which have been a challenge to ID. @Al Dentebelieves these teeth may be both be from an odontaspid shark, Tethylamna twiggsensis (Serratolamna koerti). I believe they may be from two separate families: The larger tooth from a sand tiger shark, Carcharias sp., while the smaller is a lamnid as Al Dente suggests. The options are Lamnidae or Odontaspididae. Are these two teeth from the same family, or are two different shark families represented by these teeth?

For whatever reason, I find these as interesting as a pristine specimen. Perhaps because the tooth was actually used, like stamp collectors like cancellation marks? How about you? Do you have any interesting photos of feeding damaged teeth (of any species) to share?

C.carcharius lower found on Topsail Island, NC. Approximately 2.5 cm slant height (juvenile?) Appears to have cusplets. Why?

Hi. These are a little worn down. They are all about an inch long. Any feedback is much appreciated. Thanks! Mark

Can anyone help ID these two shark teeth. I inherited my Grandfathers collection and I am trying to group them into shark type. I believe these are all tiger shark teeth. If you anyone can take a quick glance and confirm that would be much appreciated. Thank you in advance for any comments. Mark
