    Is this a fossilised bone?

    I just went fossil hunting today and found this. Is it a bone or just a rock? If so what is it? It is found in Beaumaris in Victoria. A majority of fossils are 6-5 million years old. I have theories as to what it is if it is a fossil, but I am unsure. I was thinking a an extinct penguin upper wing bone or a Pelagornis shin bone, maybe even a seal metatarsal. This is a link to a list of fossils found in Beaumarishttps://www.bayside.vic.gov.au/sites/default/files/2021-08/beaumaris_fossil_book_museum_victoria.pdf Personally, I am sceptical as to whether it is a bone but my Mum and Dad believe it is.

    Yorktown Formation Seal Jaw

    From the album: Fossils

    One of my favorite Lee Creek finds, a nice seal jaw with 5 teeth. This must have been a fairly young individual because there is almost no wear on the teeth.

    What is this bone?

    I found this bone on a beach in California. My questions are: 1. What is this bone and how old it is. 2. is the break that is fielded up with sedimentary rock was present in the original bone? If so, is it the way the bone is or it is a result of an injury? 3. Are the lines on the bone bite marks? it is around 6 by 6 cm. Thanks!
  4. Hello everyone, I need your advise. I just bought a 5" megalodon tooth that was dipped in seal oil (buyer says that this was for protecting it). I searched everywhere, talked to many people. I understand that oiling was a bad idea. I tried to clean it with warm water and soap. I would not try some substance more agressive. What should I do more than that? That oil is indeed that bad for fossils? Why is oil that bad for fossils? How can I clean it better?
  5. Its been a minute since I've posted About 20 years ago while doing research online for fossil preservation I read somewhere that curators used "B-72" as adhesive and consolidate. so I did some digging and found a supplier that offered up free samples. I ordered some and after it arrived we were moving and it was packed away. the next couple of places I lived didn't afford me the space to do my hobbies and prep my fossils. Much time has passed and I am now able to haul out some of those fossils and work on them. I dug out the "B-72" I had ordered years before and started to look up info on how to properly mix my "B-72". Low and behold I didn't realize that there are other products that use the same handle "B-72". I now see its "Paraloid B-72" or "Butvar B-76" that are most commonly used for this purpose. So what's the difference?, and can this "Butvar B-72" be used? Is there or could there be any negative or undesirable effects from this stuff? will it ruin my fossils? If it can be used, does one dilute it the same as the other products? what W/V % should be mixed for consolidating vs using as an adhesive? Thanks for any input
  6. Several months ago, someone found this tooth and I was told it was seal. But when I was doing some research on a seal molar found yesterday by someone, the seal canine looked different. I no longer have access to the tooth, but I have a few photos. These also came out of a Gainesville creek. (On private land)
  7. Hello - I recently acquired these two Mastodon jaw bone & teeth pieces and was wondering how best to "preserve / seal" these. They are pretty solid but I want to make sure that they don't get chalky or start to flake. Does anyone have a recommendation on what to do? I appreciate your input. Thank you. Tom
  8. Hey all, it's been a decent year for marine mammal paleontology: I wrote my yearly blog post reviewing all of the new studies that came out. Check it out below: https://coastalpaleo.blogspot.com/2023/01/2022-in-review-advances-in-marine.html Also - some selected images of the more spectacular marine mammal fossils described this year:
  9. Hi! I found this bone on a remote, virgin beach in northern Iceland just the other day. I’m completely green when it gets to those topics and have thus no idea what it can have come from. Possibly a piece of a large fish or seal vertebra? Any ideas? Can anybody help me identify the bone?

    Thoracic vertebra from a pinniped?

    Hey everyone, I found this vertebra back in April on the Zandmotor (Netherlands, most likely late Pleistocene in age). I believe it's a thoracic vertebra from some pinniped, but I'm not sure. I've been comparing it to several vertebrae online, especially using the Osteology section in the Idaho Virtual Museum website (which is quite good, perhaps a useful resource for some of you!). Unfortunately, I am not finding any satisfying matches. The different seal thoracic vertebrae I am seeing look most similar, but they all appear to have a less wide corpus than my specimen. I'm really hoping to be able to put a species name on this specimen; I know it's not complete, but I feel like enough of it is there to be able to make a confident species guess. But I will settle for a less specific ID if necessary. So, what do you guys think? I'm looking forward to hearing your opinions! Best, Max EDIT: just realized there are no size references on my photos, sorry! The vertebra is 8cm wide at its widest point and 5cm long. The corpus is 5.5cm wide and 3cm high.
  11. I'm going through my vertebrate collection and making sure the labels are correct before I start forgetting everything haha. I have here two small bones that I found from the Lee Creek Mine in NC. I collected the white one from the Pliocene Yorktown Fm, a marine fauna. The brownish one was collected from mine spoil, so it could range from Miocene-Pleistocene. I have them tentatively identified as marine mammal phalanges, but these are somewhat out of my comfort zone. Thoughts? I"ve tried to show the two bones from all angles. If better or additional photos or needed, please let me know Thank you in advance!

    Thoughts on cave bones?

    Hi all I have been looking through some of my cave finds and want your thoughts on two specimens that look much older than the other bones. All these bones where found in one cave that could have possibly been inhabited by humans as recently as 370 years ago, before colonialism. I have found some ostrich egg fragments as well as sea shells in the upper soil layer, this might be an indication of human activity, I have also found evidence that the site was occupied by scavengers and predators like the lynx and leopard at some points. The site is approximately 1.5km from the nearest coast and around 200m above sea level (could be higher) cave fossils, including hominid fossils dated at 35,000 years old have been found in the surrounding mountains. (made an edit on age from 80,000 changed to 35,000, this could change again as I was just reading some conflicting reports on the area, varies from middle to late pleistocene with some early to middle holocene in the mix) These jaw bones where found in a compact layer at around 300mm below the looser 100mm of topsoil. Jaw specimen 1 is probably a juvenile Papio ursinus (chacma baboon) jaw 2 is from a Cape fur seal, they feel much denser than the bones from the top soil layer, but are not permineralized (like stone) I would like some thoughts on the idea of these being pleistocene material?

    Weird sea mammal bone

    Hi guys, I found this bone on the Bulgarian shore of the Black sea, near Balchik. In the region there have been found the remains of cetotherium sp., dolphins, seals, flamingos and others. I am wondering though what exact bone it is and of course of what. I thought that it may be a part of a fin or something like that, but I failed to find a photo of a bone like this. Any help for the identification will be very much appreciated! And happy soon to be new year!!
  14. heres a link to a newly described fossil seal that we have been finding bones and skulls of here in taranaki, new zealand for the last 15 or so years. https://www.google.com/search?client=opera&hs=0U9&biw=1496&bih=754&tbm=nws&sxsrf=ALeKk01vc72KwYUUtagYwhLgRk96jWpnXQ%3A1605241533476&ei=vQquX5veHM7w9QPNhoLgBQ&q=new+zealand+fossil+seal&oq=new+zealand+fossil+seal&gs_l=psy-ab.3...33364.36178.0.37013.5.5.0.0.0.0.554.1364.0j1j3j5-1.5.0....0...1c.1.64.psy-ab..0.0.0....0.uRROVU4bIrg

    Seal or Walrus?

    hello all, it's been a while since I've been on. I hope you are all doing well in these trying times. I recently purchased a series of large mammal phalanges from Lee Creek. They're clearly Yorktown (Pliocene). While they seem to resemble seal phalanges, they're awfully large (14-15 cm). I'm wondering if they are walrus instead? Does anyone know if the last Smithsonian Lee Creek volume (Vol 4) is available online as a pdf? Alternately, are there easy "tolls" that I can use to distinguish, or does anyone feel comfortable making a distinction? Thanks!
  16. Hi all - I did not have time in January when I normally write these up, but thanks to Covid quarantine I managed to get some time last month and write up a comprehensive review on my blog of every single 2019 paper in marine mammal paleontology. Enjoy! https://coastalpaleo.blogspot.com/2020/05/2019-in-review-advances-in-marine.html
  17. Amazing day yesterday! @sharkdoctor and I spent all day at the Calvert Marine Museum’s collection sorting through and cataloging pieces of his collection either loaned or donated to the Museum. When I say amazing fossils, I mean it. Crabs, birds, whale material, possibly a new species of seal, teeth, turtle plates, and more. @sharkdoctoris a really cool guy because he focuses all on adding to science and not just trying to grow his own collection. Plus, he’s so informative! After completing the cataloging of his collection we proceeded to catalog some of Bretton Kent’s world class shark tooth collection. The incredible John Nance took us through the museums archives, showing us the only Hexanchus from Calvert, 3 inch makos, Gomphothere Teeth, rare species of shark, a whole crocodile, and other innumerable fossils that would be any collectors dream to have. Thank you John Nance, @sharkdoctorand the whole fossil community for building this up.
  18. Found this partial tooth a few years ago in some Holo-Pleistocene marine sediments on Oahu, Hawaii. There is also the chance that it is more recent, as there had been some dredging in the area, though I haven't seen any evidence at this location. Approximately half of this tooth is missing. What remains is half of the crown and one root lobe. It is 17 mm in maximum dimension. My guess is carnassial. Seal? Canid? Appreciate any and all input.
  19. In January, @Metopocetus and I met to do some map work and go through some old documents in search of productive exposures of the Eastover Formation (which generally lies on top of the Calvert Formation in Maryland and Virginia). Like all good fossil hunters, we met at dawn to do a little fossil hunting first. The wind chills were below zero (F), but there was a blowout tide. We each found a fossil shell or two and some cool pictures of interesting ice formations along the Chesapeake Bay (below) and then retired, thoroughly frozen to a warmer spot to do our map work. Working with some 50 year-old publications and field notes, we identified a passing mention to a tiny layer within the Eastover Formation that MIGHT have fossil crabs and a concentration of vertebrate material. Within a few weeks, @Gizmo and I had worked ourselves into a lather over the possibilities. The sites are remote. They are basically not documented in the modern literature and none of us could find any published record of crabs from the Eastover Formation. It sounded like a good chance at finding a new species. We found ourselves completely convinced that we could do the impossible: 1) drive hours to a waterway that we had no experience with, 2) use 50-year-old information to find the sites and 3) then identify the crabs in anonymous clay beds in shallow, freezing water On February 12, I met @Gizmo at our favorite meet-up in the pouring rain and air temps around 40F. We spent a tense couple of hours on the road wondering if hurricanes, weather or riprap had erased the sites. Just a bit after dawn, we put the boat into the water and set out into a cold and gray day. Within an hour we had checked several potential locations and found the sites to be almost exactly as described. Within two hours we identified two nearly complete crabs as well as a pile of other goodies ranging from shark teeth to random fish vertebra. However, we were pretty bummed out that we had only picked up two complete crabs on the beach. While the tide was out, we worked in clay slicks in shallow water to find more. On a hunch, we kept every nodule that we found. We couldn't see through the mud and clay, and the clay was nearly waterproof when wet. Impossible to clean the nodules. Plus, the water was just way too cold. Near the end of the day, Gizmo found a megalodon tooth and several nice makos. Soon after, we found an associated set of vertebra that I kept for trading. Anonymous vertebra and skeletal associations are fairly common in VA, but I hold onto them sometimes to use for trading with other collectors or for donating to classrooms. At the very end of the day, I stumbled on two seal bones, a humerus and metapodial, in the clay underwater. We quarried them quickly in the freezing water and scooted back to the ramp just before sundown. In cleaning up the nodules, I quickly found that the dried marl washed right off. In the course of an hour of cleaning I found 25+ crabs that were largely intact, as well a seal astragalus. In all, we ended up with several coprolites, several pounds of fish, seal and whale bones, a variety of shark teeth, and an ecphora. The little association of dolphin sized vertebra turned out to have some surprises. Three vertebra, with one complete, one with broken processes and one that has been sheared by a large shark bite (on the right). The sheared vertebra was buried in the clay underwater, but came out without any damage. The bitten surface is sheared smooth ( a modern break would be jagged) and has the profile of a large tooth (still trying to figure out how to get a profile+tooth photo).

    STH Confusion

    I have recently been blessed to acquire some excellent Shark Tooth Hill (STH) marine mammal teeth. Not totally happy on not knowing what exactly I have, I am reaching out to STH experts to enhance my knowledge and understanding (but mostly to identify these fossil). One TFF member who has extensive knowledge of STH is @ynot because he sent me matrix and micros from STH. So, Tony please invite other STH enthusiasts to assist here. After spending time looking at the Pinnipeds: Seals, Sea Lions, and Walruses teeth, both fossil and modern, I am confused about a lot of things: Here is one of my teeth to ID: Seems easy, 25 mm Seal molar.... or is it ? On a $$ForSale website , I see this STH Sea Lion tooth -- molar ? that at 1.25 inches looks the same.. So do Seals and Sea Lions have the same/similar teeth only larger? Here are 3 teeth where I would be pleased with confirmation, identification, alternate possibilities. Is this incisor an incisor or a molar ? Is it the approximate size of a seal incisor? A harbor seal's incisors for comparison. Here are the canines of a Weddell Seal... At 38 mm, Can this canine be Seal, maybe lower jaw.... Lots of questions, Hopefully will trigger a good discussion.. Jack
  21. the Most complete skull I’ve found to date. Both bottom mandibles seem to have all of the teeth and possibly only missing 2 premolars out of the top. Skull looks to be all there and possibly some other bones judging from some broken cross sections but who knows! I’ll upload more photos in the comments. The rock is 45.5 cm long 36cm wide the skull measures 26cm I’ll continue work progress as time goes she may take a while!
  22. Does anyone have a decent photo or 3 of the earbones to a seal or similar pinniped?
