    Alaska Fossil Sites

    Hoping to head up to Alaska this next summer and would love to hunt for fossils. Does anyone know of a list of sites to start looking? Thanks!

    Quaternary mammal fossil?

    I found this bone in Interior Alaska down river of some bluffs that I know have produced mammoth bones and other Pleistocene age fossils. I am curious if anybody can identify this bone and whether it is really from the quaternary or is it more recent. There is crystallization in the holes in the bone and it feels more dense than a normal bone would. Be thankful for any thoughts and information.
  4. The snow has arrived at the elevations that I like to hike covering up the fossil beds now. These pictures are from one of my last hikes in the Talkeetna Mountains and as you can see these are oversized fossils. The ice axe next to the clam is 30". Kobuk and one to the bigger ammonites measured at 65 cm diameter is another whopper. Ok, now a Where's Waldo picture. How many ammonites do you see in the picture? I have the answer and they as still are all still there in the outcrop, some are broken. The answer is nine ammonites. Until next year happy fossi
  5. Hi everyone, I recently came across online Alaskan fossils. Specifically they are a Polar Bear and Walrus tooth from St. Lawrence Island, Alaska. There doesn't seem to be much of a consensus on the age ranges for those teeth, and having those would be useful to me. According to a geological map, St. Lawrence Island, Alaska, is Quaternary at its earliest: https://alaska.usgs.gov/science/geology/state_map/interactive_map/AKgeologic_map.html. That already puts me at a range of 2.6 million - 11,000 years, pretty wide. Initial research suggests polar bears evolved maybe 150,

    Is this a fossil?

    I have here a polar bear tooth from St. Lawrence, Alaska. I was told it was fossilized, Pleistocene to be precise. The seller had other similar teeth available on offer, in darker shades, claiming they were all fossilized and simply preserved in different ways. Ultimately, I chose this one. As far as the literature goes, it has been argued that the polar bear does go back to the late Pleistocene: Ingólfsson, Ólafur; Wiig, Øystein (2009). "Late Pleistocene fossil find in Svalbard: the oldest remains of a polar bear (Ursus maritimus Phipps, 1744) ever discovered". Polar R

    Polar Bear Tooth

    I have here a tooth that a merchant claims to be a fossilized polar bear tooth, found on St. Lawrence Island, Alaska. To me, it looks like it could be sea lion. Any idea? \ Then again, here's a (replica) grizzly bear tooth that looks similar to me, too:
  8. Here is the next part of my north slope trip pictures. After camping for two days I headed west and stopped on the Canning River to fish for char. The gravel bar I landed on had pieces of fossil coral and the river cut bank was of the same Kingak Shale with some large concretions. The view out of the plane shows the Ignek valley, east and west. After fishing headed west and stopped at the Kavic Camp for fuel, bring cash as avgas is $12 a gallon and glad to get it! Saddelrochit Mountains

    Ammonite ID Help

    I have studying ammonite anatomy and nomenclature as well as the local geology where I have been hiking. Today I rough prepared several ammonites and feel like I can make an educated attempt to name 2 of 3 that I worked on. I am reasonably certain they are from member three of the Matanuska Formation in the Talkeetna Mountains. I have shared some pictures of where I found one on the snow at the bottom of an avalanche so pictures of that one first as it is new to me. In my effort to learn these will describe why I believe it is Gaudryceras tenailiratum; wide umbilicus, course ribs, rounded vent
  12. Ok, tired of AK Hiker getting all the glory for Alaska finds hehe Made a run to my local fossil spot yesterday (which includes about 3 miles driving down the beach). Try to only go down when the tide is falling to 1, give more time to explore, and 2, more time to escape when the tides rolls back in. We can have between 8 - 28 feet of tide change! During big high tides the water is to the bluff. Some of the driving is loose sand / gravel so want to make sure if accidentally get stuck have time to get the car dug out before it takes a salt bath! We're searching through
  13. Hi all - in the hopes of attempting to reach a wider audience, and anyone who has collected possible sea otter fossils, I'm sharing the first two posts from my blog "The Coastal Paleontologist" in a short series on sea otter paleontology and evolution. The first one is mostly a bit on sea otter biology, and the second is the first one that really deals with the paleontology aspect. The third (and fourth?) posts will deal with what the limited fossil record can tell us about sea otter evolution. The sea otter fossil record is quite poor, and I'm hoping that some of you may have found some fossi
  14. Wishbone Hill by Sutton, Alaska is an old coal strip mine area so unfortunately a lot of trash, motorized recreation and shooting. Did I mention shooting? On the drive in will pass where trees have been shot so much they have fallen down, I should have taken a picture of that as for about an 1/8th of a mile 50 trees have been cut down by bullets. My wife, dogs and I did an eight mile round trip day hike first with the strip mine visible in the background. There is road access to the mine area and fossil collecting is allowed. Wishbone Hill with the notch in middle for
  15. There are brown bears to watch out for. As requested some scenery pictures from a previous trips in the Talkeetna Mountains, Alaska, USA . As I get more versed in the strata and fossil nomenclature will include with the posts and finds. Notice the snow still present in June of last year and I am ready to get out again weather permitting which was a no go this weekend so sat and read numerous post on TFF for my education. Love the site and will figure out the decorum and how to interact as this is new to me.
  16. Hello! I am taking a trip up to Alaska to visit my dad. He really wants to go and apttempt to find some fossils. The goal is something other than plant species, something like gastropods, ammonites, etc. We will be anywhere from Wasilla, Ak area to Seward during our trip. Any spot suggestions would be greatly appreciated! Thanks guys!

    Alaskan Bivalve or Tooth?

    Hi everyone! First time posting here. I went out over the weekend to do something outdoors during the quarantine (easy to do in Alaska) and went to a spot known for marine fossils (especially sea lilies) on the Little Nelchina River here in Alaska. I was picking up fossils on an eroded cliff side above the river when I noticed this laying on top. My question is, is it a bivalve or tooth? I don't notice a hinge line or umbo if this is a bivalve, but this may be due to the deteriorated condition and the fact that I am a rookie at this. It appears to be broken in half, with the inside showing bla

    Tooth ID

    Hi guys and gals, I've been having a heck of a time figuring out what kind of tooth I found. I live on Kodiak Island and while beach combing, in a somewhat discreet spot, I happened across it. Please see pics...any help is very appreciated.
  19. Greetings! I spent my career as a research paleontologist with the U.S. Geological Survey (Menlo Park, California) and the California Academy of Sciences (San Francisco), specializing in Cenozoic marine mollusks of the North Pacific and Arctic oceans. My summer fieldwork for 34 years was in Alaska, Siberia and northern Canada up toward the North Pole. Several times I had the indescribable thrill of being the first collector, perhaps the first human being, to visit a remote fossil site, reached by bush plane or helicopter. I was often dropped off to spend the day alone at remote sit
  20. This paper came out today. For those who saw my post of the palm leaf in both Alaska and the Smithsonian... this explains what I was doing in Fairbanks. I was up there for a total of five weeks stretched out over five winters. Yes, Winter in Fairbanks. I was hoping to see minus 40 degrees, but it never quite made it. I am "a fossil preparation specialist worked in two-week stints over the course of several years to get the fossil cleaned up and ready for study" https://news.uaf.edu/new-thalattosaur-species-discovered-in-southeast-alaska/?fbclid=IwAR0f-Lg4vDgE5MVu

    New Alaskan Thalatosaur

  22. Hey everybody, I’m new to the forum and was hoping some of you have some thoughts on a few rock/fossils I have. I found all three of them on a gravel bar on a river in Interior Alaska. I believe the geology of the area is mostly quaternary. I believe the first specimen is part of a mammoth tooth. (A friend of mine found a mammoth scapula on the same stretch of the river.) A sedimentologist at the university in town is also leaning towards the opinion that it’s part of a mammoth tooth. I’ve never seen mammoth teeth have that type of coloration before though. The second sample looks to me like i

    Denali hwy fossil

    Found this a few years back. Didn’t know what it was so I took it to the local rock hounding club the retired geologists that attends said he didn’t know what it is and suggested possibly fossil due to the holes. the rock is oddly lightweight about 4 inches by 6 inches.
  24. Last week took a short drive (11 miles of road and 3 on beach) to our local fossil area. 99.9% of our finds are plant parts. Mostly Alder and Willow leaves with some Meta Sequoia tossed in. Some times a birch leaf will find its way in. In the right rocks I've found a number of what I believe are alder cones as well.. After I get back home I'll start working on IDs. Unfortunately the literature is scant but was given one that has some local info. Some planes will have single leaves in good shape. While others are stacked on top of each other but the leaves are damaged. It looks lik
