  1. First Trip to Ernst Quarries

    Hello all my fellow fossil lovers! This is my first post on here for a while, I've been lurking around and admiring everyones finds. But y'all have motivated me to actually get out and start hunting! I will be driving up with my girlfriend from Los Angeles to Ernst Quarries in Bakersfield, CA on March 28th. For people who may not be familiar, this is part of the infamous Shark Tooth Hill, dated to the Miocene at 12-15 mya. It is a pay-to-dig site, and not too bad at $40 for a full day of digging. Is anyone on here planning on going that day or have been recently? How does the quarry look like after all the rain we have been having? Does anyone have any tips on what extra tools that are helpful to bring? From what I have read on here, a Pickaxe is helpful for exposing the bonebed. I will also be purchasing my first Estwing Geologic Hammer (the 22 oz with pick end) for the occasion and also to celebrate finishing my semester of Paleontology. Some brushes are also helpful for cleaning up the teeth in matrix too. Anything else that is suggested? Please feel free to share your Ernst Quarry experiences and advice, if you do feel so inclined I will update the thread with pictures of the results - hopefully we will be able to find some goodies
  2. Fake or Real Megalodon?

    I work at a fossil and mineral store and they own a 3.5 - 4.0 inch megalodon tooth (the basal of the tooth is broken slightly but its still beautiful) The serrations are smooth but visible, the bourlette is defined and a darker color than the enamel. However I have my doubts about buying it. They went to a fossil show in Colorado years ago and bought it from someone at a stand (none of my employees or boss are "fossil savvy".) I'm worried about spending $ on a fake megalodon tooth. I work this Saturday and will upload photos of me holding it from the case before I decide to buy it. I saw no seams on it from a possible mold but it just seems too cheap for the size. Its color is all black, which is a good sign but those can be easily faked too. I know, nobody can determine until I post a picture, However I did want to ask if there was any specific way people use to identify if a megalodon is fake or real? I heard megalodon teeth are cold to the touch and the plastics are slightly warmer.
  3. Shark tooth ID

    Hi All Can you please help me get the accurate ID of this tooth from Sahara of Morocco. Thank you Malek
  4. Shark tooth from Nieuwvliet

    Hi all, Here’s a cool little shark tooth I got from a super nice lady during the fossil fair in Harderwijk last weekend. She found it on the beach of Nieuwvliet-Bad in Zeeland (Netherlands). I’m trying to ID it but having some trouble doing so... looks most like a Striatolamia macrota but the shape of the tip of the crown seems off, and mine doesn’t have any cusps (and doesn’t appear to have had cusps now worn off either). Anyone have an idea? The tooth’s age is ambiguous, from Pliocene to early Eocene (all ages are found on the beaches of Zeeland), but seeing that she mostly found Eocene species nearby (ie Otodus auriculatus) this is one has a slightly higher chance of being Eocene too. Thanks in advance! Max
  5. I’ve heard of fossils at all of these beaches and they’re all quite close to either other, so I was wondering if anyone knew which one’s the best as far as quantity and quality are concerned (at this time of year as well).
  6. Hello, today for trade I’d like to offer a very rare and big Russian Cardabiodon tooth. These are very rare sharks and you definitely don’t see them very often. For trade I’m looking for dinosaur material or large shark teeth (mainly Megalodon teeth, Mako teeth or Great White).
  7. Is this a megalodon tooth?

    Hello, I apologise but i am quite new to fossils. I found this today at Walton-on-the-Naze in England, in the sand below the cliffs, and i wondered if anybody could help me confirm whether it is a megalodon tooth? It seems very different to the ones i have seen online, so i am not sure - but i understand teeth come in all shapes and sizes. I will be very happy if it is, especially because it was still quite high tide when i went and i had to wade through water to get to the beach (getting my feet soaked in freezing sea water in the process! ). Thank you
  8. I had a fun hike at the North Sulphur River Texas yesterday. I figured it would be picked over but I found a pretty remote spot with my 4x4. The one sawfish tooth I found in a small creek a few days before. Everything else is from yesterday. It was a great day for Cretaceous coprolite (Poo). @GeschWhat The one coprolite is full of fish verts, bones and fins.
  9. Am asking obo a friend of mine. I personally have no interest in this item for myself. But thought I would ask here anyway as I couldn't give him an answer. Is the tooth genuine? Is the ID correct? This is the only photo he has sent me.
  10. I currently live in Tacoma Washington State ( Not D.C ) I am moving to north Carolina to rent a house and start a life with my soon to be wife. However, for the next year as I complete college, is there anywhere in Washington state where I can find shark teeth? So far I have found nada. I heard Point no Point is good for fossils and shark teeth according to a post called "Best Beach for Shark Teeth: 6 well known places to search (not allowed to post links) However after a quick search on Macrostrat and older geologic maps I have found nothing of interest in the entire area and the islands across from it. I imagine the best beach to go would be one with exposed fossiliferous sediments on cliffs that get battered by waves. If anyone knows of any places or even a simple "Yes, they exist here" would be helpful. It seems there is no info online.
  11. Last week I was on holiday in the Netherlands/Belgium for a short time and I had the chance to visit the area of Antwerp to find some shark teeth. Too bad the weather wasnt good (I think it rained the entire day). Nevertheless I found some teeth and I have to say that I am kinda satisfed with the result! I almost sieved the whole day so my body still hurts a bit The material I searched in comes from the Miocene, Pliocene and was washed up from the extension of Churchill dock in Antwerp. Here are two "in-situ" pictures: A nice tooth on the sifter: Pictures of the nicest teeth: A nice dolphin tooth with enamel (4 cm long): A dolphin ear bone: (a little bit more than 2 cm long) An Isurus retroflexus tooth (3 cm long): And an 4.2 cm long Cosmopolitodus hastalis: (I am not sure if I determined this one right ...) I think I will post some more detailed pictures of other teeth in the next days! Thanks for watching
  12. The weather has been so nice here lately that I decided to go for my first bike tour of the season yesterday. I don't like to over strain myself on the first trip, so I chose a site in the woods on the edge of a village about 10 kilometers away as my goal, knowing very well that I could spend a couple of hours scratching away in the sand and grit with my pen knife in the search for small shark teeth in the Miocene Burdigalian exposure. I have some idea what 3 of them might be, but I'd nonetheless appreciate confirmation or correction of my assumptions. I'm however not at all sure what the last 2 might be since I see just too many possibilities and am hoping that someone could set me on the right track. @MarcoSr @Al Dente @fossilselachian @Woopaul5 I'll number them for convenience's sake. Thanks in advance. 1. Mitsukurina lineata ? Goblin shark lower lateral ? 10mm. long. I think that the next 2 are both Carcharias acutissima ? Sand Tiger upper anterior ? 2. 19mm. 3. 25mm. 4. 11mm. 5. 16mm.
  13. Hello everyone! I figured I’d show everyone all of the cardabiodon and Cretoxyrhina I own! To start off here are my two cardabiodon. The left one is a Cardabiodon ricki from the Malii Prolom Quarry in the Ryazan Region of Russia. I’m not too sure how old the tooth is. The second tooth is a Cardabiodon venator from Kansas.
  14. Pennsylvanian tooth

    Hi, I found this tooth the other day near Starved Rock, Illinois. Pennsylvanian deposit, Livingston limestone. I can't seem to find a match. It's missing some bits, any ideas from the paleozoic shark experts? It measures about 7mm
  15. Shark vertebrae

    Hello, I'm new to this forum and I come here to ask for your help. I am graduating in Biology and my final paper is about identifying species of shark vertebrae from an archaeological site. The thing is nobody from my lab knows how to work with it and I spent the whole last year trying to work with these centra but I realized it is a really hard work, almost impossible. I come here to ask if any of you know some good papers about shark vertebrae that could help in my work, or anything else that could help me in this situation. I'd be so thankful!
  16. I finally found my first creek spot all on my own using maps. I recognize some of these teeth but the Hemis look a little different from what Im used to finding. Also are the tooth chunks from Megaladon teeth because if so then am I in the right spot to find full Megaladon teeth? Oh and i found this other odd fossil that Im pretty sure is a piece of alligator armor.
  17. Hi, my daughter found this in the ocean off of Sanibel Island, Florida US. We tried comparing it to shark teeth, but it doesn't seem to match any that I've seen. Hopefully someone here can solve our little mystery! Thank you for looking! I am going to attach the other photos in subsequent posts because I am getting an error that I am only allowed to upload 3.95MB, and each photo is only around 1mb so I am not sure what I am doing wrong.

  19. Sand Tiger shark

    From the album Fossil Collection

  20. I got this tooth and didn’t realize it had restoration done to the tip. I don’t collect restored teeth so am offering it up for trade for other shark teeth. Let me know what you have, I’m open to offers. Especially interested in (but not limited to) Cretaceous teeth.
  21. Hey all! This week my colleagues and I published a paper we spent most of the last decade sweating over. It is an exhaustive report of all known late Miocene-Pleistocene records of teeth of Otodus (aka Carcharocles) megalodon teeth from the west coast in an attempt to estimate the date at which O megalodon went extinct. Aside from some conspiracy theorists who will wait until they die and not see a live 'meg', we all know it's not living today as there is not a shred of positive evidence indicating its existence. We know it's around in the Miocene, and the early Pliocene. Did it survive into the Pleistocene? End of the Pliocene? or become extinct sometime earlier? These questions require serious thought because it has direct implications for whether or not O. megalodon went extinct at the same time as a bunch of weird marine mammals or if it was killed off by a supernova known to have occurred 2.6 Ma. An earlier study pooled fossil occurrences from around the globe and statistically reconstructed a mean extinction date of 2.5 Ma, with significant error (~3.6 Ma to 100ky in the future being the max and min extinction dates). We found that in the California record, reliable occurrences are only found in early Pliocene rocks. All examples of late Pliocene or Pleistocene teeth were either poorly dated, reworked from Miocene rocks, had poor provenance, or are completely missing (and never photographed) and therefore the identification cannot be confirmed. We thus predicted a 3.6 Ma extinction date. To test this, we re-analyzed the dataset published in 2014 but chucked a bunch of bad data and exhaustively re-researched the stratigraphy of each locality and corrected about 3/4 of the dates in the remaining dataset, and added our new California records. When we analyzed this corrected dataset, our margin of error (the time between the max and min extinction dates) shrank from 3.6 million year long interval to 900,000 years; *probably* extinct by 3.6 Ma (mean extinction date), definitely by 3.2 Ma (min extinction date), and possibly as early as 4.1 Ma (max extinction date). This extinction therefore precedes the 2.6 Ma supernova, as well as the Plio-Pleistocene marine mammal extinction (which in all likelihood was not a mass extinction or an extinction event, rather just a period of higher extinction/origination rate). About 4 Ma is when fully serrated Carcharodon carcharias teeth show up in the North Atlantic, indicating when the two overlapped, however briefly. We think this biotic event matches best - the mechanics of exactly how this was driven are to be figured out by someone else, but perhaps adult Carcharodon outcompeted juvenile O/C megalodon prior to becoming gigantic. Some analyses of Otodus lineage growth rate is going to be necessary. Here's the open access paper here: https://peerj.com/articles/6088/ Here's a blog writeup I did for PeerJ here: https://peerj.com/blog/post/115284881293/early-pliocene-extinction-of-the-mega-toothed-shark-otodus-megalodon-boessenecker/ Excellent summary in Nat Geo: https://www.nationalgeographic.com/science/2019/02/megalodon-extinct-great-white-shark/ CNN: https://www.cnn.com/2019/02/14/us/megalodon-extinct-earlier-scli-intl/index.html Fox News: https://www.foxnews.com/science/megalodon-shocker-huge-killer-shark-may-have-been-wiped-out-by-great-whites Forbes: https://www.forbes.com/sites/melissacristinamarquez/2019/02/14/great-white-sharks-may-be-the-reason-why-giant-megalodon-shark-is-extinct/#6a06986a6486 Daily Mail: https://www.dailymail.co.uk/sciencetech/article-6700495/Giant-50-foot-long-predatory-shark-went-extinct-one-million-years-earlier-previously-thought.html
  22. Shark jaw attempt

    Since I am finished with my shark vertebrae cluster I have decided to start on a shadow box for my otodus obliquus tooth set but my daughter insists on a jaw. So here I am trying to make a jaw but oh boy it's not easy since I have never done anything like that. The fact that I am working only with photos doesn't help much either but what you would not do for your kids :). Did enyone here made a jaw before? Any suggestions? I am not trying to scientifically reconstruct an otodus jaw, I am just after a nice display piece.
  23. Shark centrum modern or fossil?

    Just got home from a day trip to the corpus Christi area, very tired so might be a bit loopy. Found this on a shoreline sort of near the lighthouse park in Port Aransas, given the environment I don't know if it is actually a fossil that was maybe dredged out of the channel or modern. I think it is a shark centrum but I've never found one before so I could be wrong. Scale was a last minute thing, it's 28 mm long. Around an inch and an eighth.
  24. Bawdsey Trip - Tooth ID??

    Headed down to Bawdsey in Suffolk for a few hours. The beach has built up loads covering up the best big teeth grounds, still managed to find a few. Got the Striatolamia macrotas from the bottom of the shingle ridge and also a fish vertebra? (Can anyone confirm). The rest of the teeth were all from the red crag layer. Also found a possible cow shark tooth which i have never found! (Please say it is!!!) And some other fossil, i have found a lot of these previously but never as large. Apologies i cant take any better photos due to using my phone! If anyone can help with identifying these that would be marvellous! Thanks for reading guys and girls!
