  1. A trip report from a busy week that started with combing through some drilling cores of the Rochester Shale that were being dumped from an old project. No major finds, which was what I expected. I did happen to find a nice Dalmanities pygidium and a few brachiopods that look neat. This weekend I was down in NJ visiting family and took a stop to Big Brook on Saturday. Thank you to a kind member of this forum for giving me hunting advice. Saturday was very rainy, but the rainwater washing the sand off the gravel bar was helpful in my search. I am not familiar with a lot of these fossils, I have tried my best to use online resources to ID what I have. Finally, this week I am in the southern tier near Olean and working near a stream that is on private property. The stream is loaded with brachiopod fossils, hoping to grab a nice piece that hasn't been weathered and stained. A lot of pictures below, ID help is greatly appreciated. 1. Rochester Shale cores drying, revealing some weaker fractures. Finds from Big Brook: I tried to organize these from left to right for ID help 2. Vert and turtle shell piece? 3. I tried to put everything small I did not know in this picture. First tooth in row 2 and the last tooth in row 4 are ones that I am especially having trouble with. Each item here has some feature that is telling me that it is more than just a rock, but I could be wrong. 4. Best teeth that I found, very happy with these. 5. Hoping row one is coprolite. Row two could be other bone pieces? 6. Ray teeth, sawfish and other unknowns 7. Bones? 8. Bone looking r ock? 9. Crab claw and a few other unknowns. No serrations or teeth-like features on these unknowns. 10. Concretions? Southern Tier Field Pic 11. According to maps I am in the Late Devonian, Conneaut Group. Someone told me small sea stars can be found in this similar looking southern tier fossilized strata. Not going to hold my breath.

    Type of shark(s)?

    Found these two teeth on the beach at Tybee yesterday. Thinking maybe bull sharks, but I really don’t know. Thanks!
  3. Hello all, Found some nice fossils. Around Vaals in Limburg (the Netherlands), Cretaceous sediments occur. The Kalksteen van Vijlen (Vijlen chalk), Orsbach Kreide (Orsbach chalk) and Kunrader Kalksteen (Kunrader chalk) or Vetschauer Kalksteen are present. Fossils from these sediments consist of belemnites (Belemnella (Pachybelemnella) sumensis (Jeletzky, 1949) and/or Belemnella (Pachybelemnella) cimbrica (Birkelund, 1957), some forms are described as Belemnella ex gr. sumensis/cimbrica and Belemnitella sp.), sea urchins (Echinocorys sp. including Echinocorys scutata (Leske, 1778) and Cardiaster granulosus (Goldfuss, 1829), oysters (Pycnodonte vesicularis (Lamarck, 1806), shark teeth (for example Carcharias sp., Cretalamna lata (Agassiz, 1843) and Pseudocorax affinis (Münster in Agassiz, 1843) and other fossils. Many fossils are from the Vijlen Chalk (early Early to early Late Maastrichtian). Fossils from the Vijlen 0-3 and Vijlen 4-6 (Vijlen chalk) are approximately between 70.6 and 69.3 million years old (the basis of interval 0 of the Vijlen Member could be dated at 70.6 Ma). Lithology and bioclast contents for intervals 5 (upper part) and 6 of the Vijlen Member at Mamelis (Mamelis 62D-78) have indicated an age of 69.7-69.3 mya. Including the latest part of the late late Maastrichtian (Formatie van Maastricht), fossils can be between 70.6 and 66 million years old.

  4. In 2lbs of Peace River micro matrix, I found 415 shark teeth, of which 90 seem potentially identifiable. Here they are in different categories. Grid lines are spaced 1mm apart. I can get additional views of any teeth as warranted. A: Based on my experience with larger teeth, would call A1 as hammerhead. A2-A5 share many shape characteristics, but are they Rhizoprionodon? B1-B14 Carcharhinus, I believe. C1-C21 seem like lemon, Negaprion. D1, D2: posterior Galeocerdo tiger shark? E1-E5: These may all just be mostly-root fragments of Carcharhinus, and reflect a common pattern of breakage? But they were a "type" that emerged in the sorting. F1, F2: Snaggletooth G: This group contains a very common morphology I found, a blade with a single cusplet on the posterior side of the tooth. Most have roots that look broken. So maybe we're dealing with a lot of Carcharhinus that all broke in a similar way? Most of the blades show little or no sign of serrations, but maybe that's weathering (or juvenile teeth?). I am pretty unsure about these. G8 and G9 seem somewhat sand tiger like. Are many of these G teeth Rhizoprionodon? H: the odd singleton teeth. Some of these may be too weathered to ID. H1, H6 have similarities to some thresher teeth I have found. H2 seems potentially sympheseal H3 contortus? H7,8,9? lemon? too weathered to ID? H4 interesting cusplets, but I have little sense of ID H5 seems like it could be a sand tiger H10 lemon? H11 Carcharhinus with no serrations on the blade? H12 interesting, but ?? H13 interesting, but ?? H14 sand tiger? H15 thresher? H16 interesting, but ?? And for the sake of completeness, here are all the teeth I deemed not worth trying to ID: If you see anything worth closer inspection in there, I'll grab photos:
  5. I want these to stay pristine as possible. I’ve seen modern teeth age badly. I don’t want this. Please help! special teeth
  6. A lot of it is in the title post. A bit of backstory about myself, I grew up in South Carolina and spent a lot of my younger years shark tooth hunting out of boredom that turned to a fascination. I then had the misfortune of moving to southern Pennsylvania, and have not done anything of the sort for roughly 30 years. Of course I kept some of the better things from the finds as a child, a few of which being larger megalodon teeth, etc. I have two sons that have recently developed a fascination with the teeth and the species This led me to looking on the Internet to see if there’s anywhere in the relative vicinity of my world where they might be able to find something at their own. That led me to the Calvert Cliffs formation. Of course, reality being a working parent and time being expensive this is not something I will be able to do with any sort of regularity and I’m wondering any advice anyone can give on how to go about perhaps landing them in the right area. My assumption is more work to get off the beaten path having less time hunting, would be the ideal as opposed to going places that are picked over with more consistency. I’ve heard things about Plumpoint and taking large, southern walks along bayfront Park area. In essence, I would prefer a hike or a kayak trip if it would let me in the space with more potential, and again, I will go down and fly blind but always like to ask questions as you never know who might point to the right direction
  7. My wife and I just returned from a trip out west (western USA for our international friends) which featured a trip to the famous Miocene site near Bakersfield; Ernst Quarry or Sharktooth Hill, whichever name you prefer. As most of you know this site it well known for the rich fauna of sharks teeth, marine mammal bones and other related items and has been written up numerous times on TFF going back over the years. We had originally planned this trip a year ago, but a family emergency caused us to reschedule. So we decided to try again this year and picked late April to try and avoid the "rainy" season and beat the start of the summer heat. One out of two isn't bad - haha. We had beautiful blue skies but unfortunately had an unseasonably early heat wave that had the temps climbing into the upper 90's! My main goal of this trip was to find some of the beautifully preserved, richly colored, good sized sharks teeth (Mako's being the most common) that I have seen millions of pictures of and read dozens of trip/ID reports about here on the Forum. It seemed with a diligent amount of work digging and sifting, I was sure to come away with a bagful of beauties! This is where my caution part comes in. We had a good trip, but the results were no where near our expectations. I have been fossil collecting for over 40 years and have had plenty of down days/visits/trips, but when we walked away with maybe a dozen teeth and the largest complete one at just over an inch long from a site that represents supposedly one of the richest around after a whole day of steady digging, suffice it to say, we were a bit let down. We worked steadily throughout the day, tried several different spots and outlasted everyone. As the day heated up most of the folks were gone by very early afternoon, we had the place to ourselves for the last couple of hours before we bailed out just after 4 pm (the car thermometer read 99 when we left). We had to be out by 5. From what I saw of about half the other collectors that I talked to, were similar results, a modest number of teeth, nothing very large. Someone may have found a ton of great stuff, but I did not hear or see it. So, my caution is not that this place is not good, don't go: no, not at all. It is to keep your expectations realistic. There is no doubt I oversold this to myself. I found some nice teeth as you will see below, just not the size or quantity that I thought was the norm out of here. It could be I had a down day, it could be I didn't know the best spots to dig, it could be the quarry just does not produce like it used to, it could be that I just didn't move enough dirt to support my expectations, it could be a lot of things. But when I raised my expectations to high levels on a trip half way across the country that this was the focus of, I guess I kind of set myself up. Keep it real!!! I mostly bring this up as I often see on here that people would love to go here, it is on their bucket list, etc, etc. Again, I'd encourage you to visit, just keep your expectations in line, dig as much as you possibly can, and you will probably find the mother lode! Ok, enough of my blathering. The trip was fun, we did find some nice teeth, the preservation of them is excellent for the most part and I am working my way through some matrix I brought back which contains some very cool little teeth in there. Here is what we found: The whole kit and caboodle with my tentative ID's scribbled on the paper towel. I will follow with close ups of most of them. This was actually the first tooth we found, just an edge sticking out of the chunk of matrix (on left). On the right is after a bit of prepping so you can see the whole tooth. I think I'm going to do a bit more shaving down but leave this in the matrix. The round object by the root is just a pebble that was in there. I also found another small sharks tooth as I was removing matrix that is no longer in the picture. These Cosmopolitodus hastalis are the most common tooth found in the Round Mountain Silt from what I read (and my 1 day experience). These Cosmopolitodus planus (Hooked or Curved Mako) were neat and more the size I though we would encounter. Unfortunately, neither of these are complete. These tiny ones we managed to see as we were sifting. Since my napkin writing I have learned they are indeed a Carcharhinus, but the species seems to be an ongoing topic of discussion (not uncommon for this genus from what I have found). In the matrix I am picking there are lots more of these but that will be a topic for a future Micro post. These three are some of my favorites, very neat little teeth. Since the napkin writing, I have found the the upper sharks tooth may not be Hemipristis but rather a Hexanchus upper anterior. If anyone can corraborate from this picture that would be great, otherwise I'll probably make an ID post for a couple of these items to sort them out. These small ones are also nice. I see I did not take a picture of the most diagnostic side of the Squalus, but it does have the finger like extension to below the root on the other side. I also have found several more of these in the fine matrix. And lastly for this group a neat little bone that I believe is a cetacean periotic. I saw another post in which @Boesse identified a similar looking one as Aulophyster morricei, but there were some differences between this one and that post which I don't know if its due to simple variation within the bone or it is a different animal. Again, if I can't get a confirmation or different ID based on this one picture, I'll be happy to create an ID thread. We also found a lot of bone, I brought home a bag full of some of the bigger chunks I found in one area. I only recognize some rib fragments (second pic) and a possible beat up vert (third pic in middle). I'm not sure what the rest of the fragments represent. And finally, just a quick bit on the matrix I brought back. I did a quick sieve separation in the field just to have a mix of different sizes. This turned out to be a waste of time as the matrix was too damp to properly sieve. When I got back home and had water available, I was able to quickly run it through a small series of sieves and get down to some pickable matrix. I used a window screen (about 12-14 mesh) and a 40 and 60 mesh sieve. 95% of the matrix was fine silt (hence the name of the Formation) and went through the 60 mesh and therefore contains nothing that I'm going to spend time on (60 mesh is 0.25 mm, too small for me to try and pick with the equipment and dexterity that I have). The material caught on the 13 mesh contained almost all the sharks teeth but only represented a small baggie of the couple gallon bags of matrix I was able to fit in my luggage. You can see in the picture below the small bag of matrix to the right and the little beaker contains about 26 cm3 of fossil material picked (about 17% of the bag volume). This is mostly small fragments of broken bone but there are lots of shark and ray teeth in there as well as a few other items (future post in Micro section). I have only looked at the 40 and 60 mesh material a little bit. The 40 has a few very small ray teeth, and some fish teeth (and more broken bone fragments). I have not seen much in the way of identifiable fossils in the 60 mesh material yet. That is all for now, thanks for following along. I appreciate any thoughts or comments on my ID's or anything else. Mike
  8. My 9 old and I are headed to the Outer Banks for adventuring and he really wants to find shark teeth. Anyone willing to share some beaches? We'll only be there a few days, so I'd rather not waste time beach combing every beach. Lol We're staying in Kill Devil Hills, NC.
  9. My 15-year-old daughter and I dove Venice, FLA, on the 28 and 29 of March, and here’s our 2 day haul (6 dives). We had a great time. Some of the dugong ribs have possible bite marks as well. Doing it again in September!
  10. Hello All, First time posting. Joined up due to a fellow fossil hunter's request that I do so. Went out to Big Brook Preserve this past Sunday (4-23-23) and came away with a good selection of the usual suspects but one stood out. A nice Mosasaur tooth seen at the top of the pics below and in my hand in the following pics. Thanks for looking and thank you Sam for the company, the friendly conversation and helping with the fossil id. Happy Hunting everyone!

    Are These Shark Teeth?

    Hey guys, I'm new to this site and forum. I was just at Tybee island in Georgia and found these on the beach. I was wondering if someone can tell me if these are shark teeth. I've found some down in Venice beach in FL before but these look different. Almost as if the root broke off but the curiosity is killing me. Any help would be greatly appreciated!
  12. Yesterday another fossil hunt in Late Cretaceous sediments (early early Maastrichtian, perhaps some fossils from the late late Campanian are also present but possibly only early early Maastrichtian (earliest Maastrichtian). These sediments and the Formation itself is around 70-68 and/or 71-67 million years old. Found some black, brown and light coloured belemnites (often broken parts of the rostrum and one broken one embedded in chalk), some very small shark teeth (1mm-1 cm), and one big sea urchin in chalk (Cardiaster granulosus (Goldfuss, 1829). My girlfriend found the sea urchin and was very happy because it is the first Cardiaster sp. she found. All of these organisms lived in the Cretaceous sea that covered Europe between 70 and 66 million years ago (including during the end of the Cretaceous, the late late Maastrichtian).

    Late Cretaceous fossils

    Today: fossil hunting in Cretaceous sediments of the Netherlands. Very good weather (warm) and good finds. Including one belemnite phragmocone (internal cast)! These fossils are from the early early Maastrichtian or latest late Campanian (70-67 mya and/or 70-68 mya). Names are included. Only the brachiopod/bivalve I don't know the species name.

    Ozan Formation Sharks

    I have been trying to finish up my ID's of small teeth I collected last year from Moss Creek in Texas (near the North Sulphur River). This material is Upper Cretaceous, Campanian and I have found at least a dozen genera of sharks with Cretalamna, Scapanorhynchus, Pseudocorax and Squalicorax being the most common forms. I'm going to start with seven teeth that I think may be the same but I can not put a name to. I have been through the references I have specific to this formation or age, elasmo.com, and many very helpful posts on here, but I am still at a loss. In Welton and Farish, they look most like Microcorax crassus, but those are supposed to be somewhat older, and even then there are still some differences. They may be posteriors of one of the more common forms, but I have not found a good match yet, so I'd appreciate some help. I'll tag a few a the folks I know are usually pretty good with this stuff: @Al Dente, @MarcoSr, @ThePhysicist, @fossilsonwheels and a couple I know have collected here recently: @EPIKLULSXDDDDD, @Ironhead42 I do not see any serrations or nutrient grooves on any of them. My pictures from above did not come out very well, so I'll just post a couple (with matching numbers from above) that I think show the patter most of them have (flat on the one side and quite convex on the other with a more expanded root). Thanks for any advice you can offer. Mike
  15. I have read a couple of articles about people finding fossils in Aiken, SC. I will be presenting at a conference down there in April and will have a few hours to attempt some hunting. Not asking for specific locations~ but if you have hunted in Aiken, did you find fossils in creeks? surface hunting? I'm going to begin scouting locations online, but I figured I should put these questions out there to narrow down my search! Thanks! Shannon
  16. Hello everyone! I have recently been working on a project which includes precisely identifying shark teeth from the Campanian of the middle east. digging in the literature just made it clear that its REALLY messy. There is one promising resource however - Henri Capetta's guide to all mesozoic elasmobranch teeth. Does anybody here have the book or know someone who may have a copy? It would be a TREMENDOUS help! Book: Cappetta H. Chondrichtyes II. Mesozoic and Cenozoic Elasmobranchii: teeth Handbook of Paleoichthyology 3E, second edition,Schweizerbart, Stuttgart, 1–193, 2012. Here are some images of the finds, Welcome to share ideas on them too Dolev
