  1. 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.
  2. 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!
  3. 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
  4. 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.
  5. 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.

  7. Crabs, seals and shark bites

    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).
  8. 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
  9. Seal tooth

    So a while back, like a year and half or two years, I found one of our more prized fossils in a creek. I had no clue what it was - I mean I knew it was a mammal, but it certainly wasn't a dolphin or anything like that. Later at a PPS meeting, Bobby and Sarah ID'd it as a true seal, p1 premolar. I later decided to showcase it by doing a painting and mounting it along with a drawing of the dentition to show where it goes. Such a great tooth and I've not found any more since. *note: the painting is of a modern day gray seal - it was the closest in dentition that I could find
  10. 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!
  11. Does anyone have a decent photo or 3 of the earbones to a seal or similar pinniped?
  12. Seal or porpoise tooth?

    Found this at Calvert Cliffs. My first thought was a porpoise tooth, but is it possibly a seal? Thanks!
  13. Greetings, fossil folks. After posting an ID question the other day, and getting all excellent responses, I figured I had done my single"drive-by" post, as I just don't have any other fossil material to share. Then I flashed on a fossil that has been residing in the same place, my mom's walkway, for what may amount to a mere 1/500,000 of its life, or approximately 50 years. My folks bought their house back in the early 1970's. I was 15 or 16 at the time. The hardscaping was done with a lot of flagstone. Exposed on the surface of one slab, was a tooth of some sort, with more than 1/2 of its enamel intact. I recently showed it to my girlfriend, who thought it was pretty cool, and wondered why nobody had liberated it from the flagstone. I guess nobody had ever really thought about it. Anyway, I'm curious as to what type of creature it may have been from. My GF was thinking shark, but I have always thought it must be something else, as it looks rather canine to me, and doesn't seem to have any serrations on the edges like shark's teeth I've seen. That said, the base does seem more shark-like. So, my friends, what is it? Many thanks in advance for your help. My apologies for not including a scale reference in the image, but the length is ~30mm and the width of the base is ~27mm. I hope that helps. BTW, if folks here think it's worth saving, please offer advice on what to do to preserve it. Cheers.

  16. Whale And Porpoise Teeth?

    I have two teeth shown below. The long skinny ones I have been told are whale teeth and the other I was told is a porpoise tooth. I found images in a book showing it may be a wolf sized dog, a seal or or possible a whale shark. Anyone have any opinions? I have a few of both in a display shot in the last image. Thanks in advanced for the input!
