  1. Need help identifying these teeth. Some look so similar and I can’t be sure which shark they’re from. I am an armature enthusiast! thanks in advance! You guys are great!
  2. WOW, what a day! Today I had the pleasure of finally meeting @Jared C after over a year of reading his trip reports and admiring all of the incredible finds he's made exploring the Cretaceous formations of Central Texas. We have a lot in common: both of us are pursuing a career in paleontology, are both (almost) the same age, and are both attending universities in-state that are only an hour and a half away from each other. Needless to say, I can't believe it took us this long to finally go on a hunt together. Jared drove up from his new place in College Station this morning to meet me at my apartment and from there we set off in search of an exposure of the Eagle Ford formation I wasn't sure existed. Last spring I became very active in the geology society here at Baylor, and as a result I found a treasure trove of old literature published by the university in the '70's and '80's. More than a few of the many booklets, articles, and papers I searched through contained almost exact directions to several interesting locales that were apparently known for producing vertebrate material, specifically shark teeth. I cross referenced Google Maps, marked the spots likeliest to be the ones I had read about, and then....did nothing. I was a little too busy with school work at the end of last semester to have the energy to go scout out new locations with a high probability of finding nothing, and so I sat on the information I'd found. Flash forward to earlier this week when Jared and I were talking to each other on Instagram about the incredible plesiosaur tooth he recently found and the topic of the exposure I had read about got brought back up. It wasn't long before he had made plans to visit and help me do some legwork in a formation he was much more familiar with than myself. Just after noon we arrived at the spot. Getting to the location I had predicted to be the exposure was incredibly easy, and in no time my hunch was proven right when we found ourselves facing a steep wall of grey shale. It's worth saying now that I'm a believer in luck, specifically as it relates to fossil hunting trips. Almost all of my best finds have been found when I was with other people. With Jared being so notorious here on the forum for the insane rarity of some of his finds, I had high hopes that some of that luck would rub off on me today - and it seems like it did! Less than a minute after arriving at the Eagle Ford exposure I spotted a Squalicorax falcatus tooth lying on top of some loose shale. I was incredibly excited, as the only shark teeth I've ever found coming fresh out of the formation they originated from is the Grayson that's exposed most famously at the Waco Pit. Even better, finding a tooth this fast meant that that there must be a lot more to be found. Jared congratulated me on the find and the two of us immediately started scanning the shale for a line of shell hash that might indicate more teeth. After what could only have been two or three minutes at most, I laid eyes on my best find to date. Sandwiched between a couple of roots and a thick layer of sandstone was a line of tooth sockets extending directly back into the wall of shale. If I thought I had been excited by the shark tooth just a few minutes prior, I was wrong - NOW I was excited! After several exclamations of "oh my god I found a jaw!" Jared hustled back over to where I was standing and confirmed that yes, my eyes weren't deceiving me. We took a bunch of pictures from several different angles of the bone as it was without being disturbed in case it turned out to be a significant find or if there was articulated material covered up by the shale. Here's a view of the shale wall with my gardening knife marking the spot just below where the jaw was located: After examining what portions of the jawbone we could see that were already exposed, Jared ruled out marine reptile pretty fast. That left bony fish as the only real contender. Based on the shape of the jaw and the differently-sized sockets, I reasoned that we had a Xiphactinus on our hands. With a tentative ID, probably as many pictures taken in the span of a few minutes as possible, and the exact location marked on my phone, all that was left to do was excavate the fish. This proved to be incredibly challenging. Shale is a lot easier to separate and break apart than something like limestone, but unfortunately it's also more similar to soil - roots surrounded the fossil on almost all sides and would be a pain to remove. Jared's pocketknife and the serrated edge of my gardening knife were both pretty blunt, but after several minutes' worth of sawing away we were able to remove the offenders and clear away some of the overburden in the process. What was immediately clear was that what was exposed wasn't a jawbone, but instead the maxillary, with what seemed like a fair amount of the skull and facial elements attached. Traversing the rest of the exposure to find more shark teeth no longer seemed like the direction the day was headed, but to say I didn't mind would be an understatement! During the hours we spent crouched amongst the loose shale, slowly chipping away at the earth around the fossil with a dental pick and a knife, I was immensely glad that I had waited to explore this location with someone else who knew what they were doing when it came to articulated remains (and in this formation no less!), as I had never come across anything like it before. Jared's knowledge from his mosasaur excavation and time spent in the Hell Creek was a lifesaver. Thankfully he had also decided on a whim this morning to bring Paraloid pellets and acetone which saved us a trip to the local Lowe's. After a while it became clear that there wasn't an end to the fish in sight and more overburden shale would need to be cleared out of the way before we continued any farther. Jared produced a roll of aluminum foil from his backpack and we got to work wrapping what was already exposed. Once protected by the foil, the risk of falling shale damaging the fossil was greatly decreased. Once the overburden was cleared it was time to get rid of some more pesky roots. Distinguishing between shale and bone became increasingly difficult as the hours wore on. In many places the bone was the exact same color as the shale that surrounded it. As a result, a couple of pieces were broken off by accident, however, videos were taken explaining where they came from before they were glued back into place. After a while Jared and I both needed a break and some time to stretch our legs. We ended up following the exposure further away from the direction we came from. I followed Jared, and so I squinted my eyes to try and see if I could spot a shark tooth he might have overlooked. That's why I was so surprised when I found an ammonite right next to the snakeskin he'd just been examining. Jared had just started walking away again when I pulled the ammonite out of the shale, flipped it over, and spotted a tiny Ptychodus tooth clinging to the underside of it. After getting home and pulling the tooth out of the matrix tonight, my best guess is that it's a posterior tooth from Ptychodus anonymous, one of the more common species from the Cenomanian; although decurrens is also a possibility. On our way back to the dig site Jared spotted a large slab of limestone with some really eye-catching gastropod internal molds. I wonder why they all seem to be facing the same direction? Finally, after several more hours spent uncovering and preserving the sections of bone we could see, the sun was beginning to set and that meant it was time to leave. The chances of getting the skull out in one piece before we left were looking very unlikely. Jared had initially been optimistic and I wanted to be as well as I knew the forecast for this upcoming week looks like multiple days of rain. Unfortunately it just wasn't doable. We both decided it would be best to cover up the bone still in place with tinfoil and take the assorted loose fragments with us. I took another look at what he had exposed and did a quick mockup later of what the portion of the skull I think we uncovered today looks like (although it's debatable whether or not the orbital is part of that portion just yet): All-in-all, today was one of the best days of fossil hunting I've ever experienced, made even better by great company, amazing finds, good weather, and excellent ice-cold lemonades from Sonic after Jared and I headed home. Some time this week I plan to speak with the paleontology professors at Baylor that I know personally and get their opinion on what should be done next. There is obviously more bone to be found than just what Jared and I were able to uncover today, and I don't have the equipment or the expertise needed to do it properly. Luckily I know quite a few graduate geology students who would be more than willing to help. With the direction of a professor or two we should be able to get the fish out in one piece. I'll make sure to keep everyone posted! I know this is just the sort of thing that I'd be waiting every week to hear more about. Until then.... - Graham
  3. Last summer I posted a trip report about finding some Pennsylvanian black shale in a river bed in East Central Illinois http://www.thefossilforum.com/index.php?/topic/106753-628-illinois-black-shale-trip-w-listracanthus/. I was able to visit the site again once more in the fall last year when the river was running much lower and collect more and larger pieces of the finely bedded and fissile shale. Since then I have been slowly splitting and going through the rocks I brought home, and finding many interesting fish parts- that is definitely the dominant fauna present, disarticulated and scattered fish remains. I have also found frequent inarticulate brachiopods, one piece of woody material and a few small poorly-preserved spiral shaped invertebrates- they could be gastropods or Spirorbis. In this thread I’ll be sharing my finds from the above-mentioned site, as well as any other ones I may find in my explorations in Illinois and Indiana.

    Cretaceous Shark Tooth?

    Anybody can identify this Tooth? Found in cretaceous, turonian sandy-limestone in Poland (Tyniec, Cracow). I think it's a Shark Tooth, or other fish but I don't know which exactly.

    Shark Teeth ID Request 3

    Hi all, I have these 2 teeth that were given to me several years ago, I'm unsure what they are but think they are the same species. Could someone please ID? Many thanks, Amy

    Possible Parotodus benedeni tooth

    Hi all, A longer time ago I found a thick shark tooth from the Tertiary (about 3 cm long). From the Netherlands. It looks like a Parotodus benedeni tooth (a very thick rooth and thick tooth overall). It looks like the one on this site: LINK Perhaps other opinions?

    Miscellaneous Bones

    All found along the beaches anywhere between Onslow Beach and Holden Beach, North Carolina. If you would like more pictures of anything please let me know, thanks. The shark tooth is strange to me because I thought it was a fragment but the serrations on both edges make it seem otherwise like a newly grown tooth? I have plenty of shark teeth and no problem identifying them but this one stumps me. As far as number three goes, I thought it was a piece of turtle shell but my geology professor thought it may be a very worn tooth, however he wasn’t sure.
  10. Howdy! I recently went to Post Oak creek, and ended up with more matrix than I can immediately use. Rather than let it sit unsearched, I figured it was worth a shot to post some up for trade here. Each bag has a pound of material in it, and they have proved to be very productive. I’ve found numerous ptychodus teeth, a (poorly preserved) lobster carapace, shark and fish vertebra, various bones, coprolites, and of course, lots of other shark teeth. So there’s lots of different things that can be found. I’ve got around 25-30 lbs I’d be willing to trade. I am primarily interested in vertebrate material, but I’ll also look at ammonites, and really anything else since I’ve finally gotten back into collecting again.
  11. Hello, I've heard that some locations are better than others for finding specific species. My favorite shark teeth to find are those of the snaggletooth shark, so I was wondering if anyone knows where I might be able to focus my hunting in order to find the serrations of my dreams! I live in PA, but am willing to drive as far as Virginia if I have time and money. So far I've found baby H. serra teeth at Matoaka, but as I'm a new fossil hunter I haven't had a chance to check out other sites yet. Any recommendations? Thanks!

    Why no Ptychodus in NJ?

    Teeth of the shell-crushing shark Ptychodus sp. are fairly common in the Late Cretaceous deposits of Texas and are also found in Alabama and Kansas (and maybe other states). However, Ptychodus seems to be completely absent from the Late Cretaceous deposits of New Jersey. Why is this? One explanation I can think of is differences in age- the Late Cretaceous formations at Big Brook and other famous NJ sites are Campanian or Maastrichtian, while my understanding is that the Late Cretaceous deposits of Texas and Kansas are a bit earlier. So perhaps Ptychodus became extinct after the Texas/Kansas/etc. formations were deposited, and just before the New Jersey formations? Or was there some subtle difference in the environment between those other sites and New Jersey? All theories are welcome; theories solidly backed by fact, or that have been published by professionals, even more so. Thanks.

    Cretaceous of Limburg

    Hello all, Today I found some very cool (and rare) Cretaceous fossils in Limburg (The Netherlands). Belemnites, one sea urchin (Echinocorys sp.) and 2 rare Phragmocones (from Belemnites) were also found (two on the left corner). And also sharkteeth! Can anyone help me with identifying the shark teeth? (max size is 1 cm). Kind regards, Ruben

    Megalodon!

    Hello all, I made two drawings (and edited both of them) of a O. Megalodon (Otodus Megalodon) shark. The first one is a pencil drawing (black-white) on a original white background (made it coloured, blue). The second one is a Megalodon smelling whales. Enjoy! Perhaps other people can post here their Megalodon drawings/paintings. Kind regards, Ruben

    Fossil id (Calvert MD)

    Hi! First, thank you to everyone who responded to my older post asking for fossil hunting tips- I used as many as I could and I found some great stuff! Here's what I found and can't ID myself from my latest trip to Flagponds (Calvert MD). I was thinking 11 might be snaggletooth shark, and 19 and 20 looked like they might be from some kind of white shark though I'm not entirely sure? In addition to those I'm especially interested in identifying 1, 3, 4, 5, 8-9, and 13 but haven't been able to so far. I'd appreciate any help identifying these and the other teeth I have pictured! 36-48 are possible bones and bone fragments which I thought might have some potential for ID. If different angles or views are needed for any of these I'm happy to take more pics! Lighting in my house isn't ideal so these are the best I could do without taking pics of each bone/tooth individually. Oh they posted all out of order, sorry about that!

    Calvert Beachcombing Tips?

    Hi guys! So I'm planning to go back to one of the Calvert County beaches to try my luck again- I haven't had any success with finding teeth bigger than about a quarter inch and I'm hoping to find something a little bigger next time. My current technique is to dig up sand from the water and sift through it super carefully- should I switch it up and try something different to find big teeth? If so, does anyone have any recommendations for how to find them? And, final question, which beaches are good for finding larger specimens? I know Purse and Matoaka are good for quantity but I don't know which are best for finding big fossils. I'm still very new to tooth hunting so any help would be appreciated!

    Calvert County Fossils

    Hi everyone! I went to Flagponds in Calvert County MD a few weeks ago and came back with my biggest *actual* fossil haul so far (I posted here my first time with about 50 barnacle pieces)! I know there are a few ray plate fragments in here, and I've included what I think are bone pieces although I'm not entirely sure. Anyway, I'm having a lot of trouble identifying my shark's teeth, so any help with this would be greatly appreciated! I'll post numbered photos of my finds with this. If anyone needs a zoomed in, clearer or different angle pic I'm happy to provide more. (Advance apologies for the broken down photos, these teeth are really tiny so I had to take multiple pics to make them visible)
  19. Hey there folks, I am cataloging some specimens I collected back in 2008 from the Bergstrom Formation of the Navarro Group in Travis County, Texas. I have some great papers on the invertebrates but not the vertebrates. The age is Maastrichtian. In particular I have a rather nice Enchodus tooth and some small, but well preserved, shark teeth I am trying to ID. I have the Walton & Farrish book and have visited Oceans of Kansas but they are still not getting me where I want to be. Thanks up front, Erich

    Fossil Shark ID help please.

    Hi folks. My turn to ask for ID help. I’m more of a dinosaur tooth and fossil guy. My friend gifted me these fossil shark teeth. Can you take a look and help me with these? I own a couple Meg teeth and other Shark teeth, but these are giving me a little trouble, or I’d like verification. The first two (A) and (B) have a bourlette, but proportionately large serrations like a Great White. Except GW teeth don’t have bourlettes. I believe (C) and (D) May be Carcharocles hastalis. Are they? I believe (E) is a Mako. But what species? Lastly, is (F) Carcharocles angustidens? Sorry, no locality info on any. Thank you all for looking.
  21.

    Shark Teeth St Augustine Florida

    Ok I was lucky to find these shark teeth in St Augustine last week. But help with identification please. My guesses are Mako top left followed by Sand Tiger and lastly a small Great White? Or could that be an extinct Mako? Thanks for your help.
  23. Are Isurus praecursor and Macrorhizodus praecursor synonyms? I have conflicting accounts on this and would like clarification please. Thank you, Bellamy

    FLORIDA FOSSILS I HAVE FOUND SO FAR

    heres some photos of finds i have found at my local creek in pinellas county, FL decent finds for what was left behind, theres a lot to be explored over in the area and its a good site so im gonna work it for a while and see if anything important shows up
  25. Good evening to all participants! I have accumulated a lot of local (from Ukraine) material - I decided to sort it out, and recurring fossils, or not of interest to me, offers you an exchange. Everything in the photos is one lot. Consists of: 1. Tile from Carboniferous period with fern print; 2. A fragment of the armor of a armored fish Podolaspis Lerichei of the Devonian period; 3. Tile with Silrian brachiopods and tentaculites; 4. Mollusk of Neogene; 5. A small fragment of a fossilized araucaria of the Carboniferous period with quartzite crystals; 6. 2 fragments of orthoceras (found together with a tile with tentaculites); 7. A selection of teeth and vertebrae (most of the Cenomanian fish): 7.1. 3 Enchodus teeth (2 large ones are glued from fragments, and the largest (light) one is also smeared with a children's felt-tip pen), Cenomanian. 7.2. Ptychodus teeth (light - Cenomanian; found personally, and dark ones got by exchange); 7.3. 2 undefined teeth of the Cenomanian fish and good teeth of a shark from Malin, Zhytomyr region (by the way, dark teeth of Ptychodus are from the same place); 7.4. 2 Pycnodus teeth - Cenomanian. 7.5. - A bag of Cenomanian fish vertebrae - about 50-60 pieces. Perhaps some of this will interest you. What is interesting to me: first of all, on marine reptiles and dinosaurs, and also offhand, I am interested in the teeth of megalodon, Crinoids and ammonites. Surely I missed something - I ask you, do not hesitate to write to me in private messages - i will glad to talk. Best regards, Svetlana
