    Agatized bone?

    I picked up this curious, largish piece at an estate sale. I have no formal --or informal! -- fossil knowledge but have always collected interesting rocks and frequently have a few in my pocket. The owner had labeled this item as being from NE-central Oregon and they had mounted it with fence wire to a board. (It obviously struck them as interesting, too.) Judging from other items, the family did some elk hunting. I thought they might know bone when they saw it. Thanks for any help!
  2. We went camping last weekend out at Delintment Lake in eastern Oregon. We went to check out the ammonite fossils. It was a great place! Kids loved it. Here are some of our finds. Interesting area because you could dig in one area and it was really loose compacted clay and in another area less than a mile away it was hard slate type material that really needed some work to get it to split. Naturally the slate material had the more robust ammonites.
  3. So, I'm starting a small reference (already have most of the books specifically on Oregon fossils by local authors), and have just added "Microfossils" by Armstrong and Brasier (somewhat expensive book). I've found and downloaded (using my libraries access to academic journals) a couple of thousand pages of research articles on The Keasy (K) and Pittsburg Bluff (PB) formations (as well as those formations that are similar in species). Since the depths of the K and PB formations are from 10,000 feet (or greater) for K, and up to and including shoreline for PB, there are a significant number of

    Fossilized finger/toe

    I believe i have found a fossilized toe/finger, you can see in the cross section of what looks to be exactly what you'd expect if you cut a finger off.. You can see the meat of the finger with the bone in the center but you can also see the density/thickness of the bone as well as the bone marrow.. We found it in the Willamette River years ago and thought it was quartz or something until a friend pointed out the resemblance of a finger.. What do you guys think?

    Heliolites Coral ?

    Howdy, I was wondering if anybody could tell me what they think about these rare coral fossils that I find on the Oregon Coast. They are agatized and take a nice polish. Thank You

    Help with ID - found on Oregon coast

    Hi — we are new to this and are wondering about this find…. Our 3rd grader says petrified wood with amber. Grandpa thinks it might be bone. Someone else suggested palm wood. Maybe someone here can help us get a more definite ID? Picts are from an IPAD / IPhone. Found in Southern Oregon on the beach. Thanks everyone…

    Stain or soft body fossil?

    Thanks for looking.... I have put this piece in the junk pile twice, But I keep pulling it out. Found in SW Oregon, Western Cascades, Miocene, Little Buttes Volcanics. Measures about 30mm by 25mm, Here is a link to the site it was found, in fossil hunting trips. The piece was already split open on the ground and I did not look for other pieces, Because it looked like a stain?

    Tooth fossil? Help identifying

    Hello I was wondering if anyone could help identifying this fossil. It was found around Eugene Oregon. Thanks

    Oregon Coast trip finds.

    We got back recently from a trip to the Oregon coast. We went fossil hunting a bit north of Newport. Here are a few of our finds. We have never hunted on the coast for fossils. It was in very soft matrix and they were loaded with small concretions. We brought a bunch home and cracked them open and found many had shells.
  13. The Long-Lost Tale of an 18th-Century Tsunami, as Told by Trees Local evidence of the cataclysm has literally washed away over the years. But Oregon’s Douglas firs may have recorded clues deep in their tree rings. Max G. Levy, Wired Magazine, September 29, 2021 the paper is: Dziak, R. P., Black, B. A., Wei, Y., and Merle, S.

    Visited the Oregon Coast

    I recently visited the coast of Oregon and was able to beach comb along the Oregon coast from about Florence to just a bit north of Newport- an area spanning a short stretch of about the middle coast of Oregon. My sister lives along the coast there and she also loaned me her spare vehicle, "Greg the Van", for my adventures. I was particularly interested to visit Agate Beach located a little north of the Yaquina Bay area for agate and fossil hunting and I found a few interesting things from around there. The trip was planned late and I didn't have time to do a lot of self-education about t

    Beverly Beach Bivalves

    Recently got back from a trip out to the Oregon coast. It wasn't with the expressed purpose of fossil hunting, but I was in the area, so I spent a couple of hours at Beverly Beach breaking some loose rocks (digging into the Astoria Formation itself is strictly prohibited). A large Pecten with my hand for scale. Too big to keep. A couple of Anadara. A miniscule but well-preserved naticidae, or moon snail. A Katherinella, which I still have to remove from the matrix.
  16. Salutations FF! Sometime next week I'm planning to come down to the Central Oregon Coast (Sort of around the Newport area). I'm planning on hitting Beverly Beach, Agate Beach, and South Beach in hopes of finding some shells and with the blessing of the fossil gods, maybe an aturia. Was wondering what kind of experience people have had at these beaches, and if there are any other places worth hitting in the area.
  17. My wife found this fossil while we were digging for ammonites up by Delintment Lake in Oregon. I believe this area is from the Jurassic period. Thanks for any help. I will post other pictures of the ammonites we found. Also, maybe someone can tell me if there are ammonites under these raised round pieces that we brought home. Figured I would give it a shot at trying to uncover them.

    Fossil Polypore

    I found this specimen digging in the Hampton Butte area of Oregon. It was found with typical pieces of petrified wood from the area. It looks very much like a polypore/conch. I know fossilized mushrooms are very rare but I’m stumped as to what else it could be. Thanks for the help!
  19. My daughter found this seed pod Sunday at the John Day Fossil beds in Oregon. Pretty cool. Found a lot of seeds by themselves but this one is the actual pod. Just thought I would share it.
  20. I found this fossil on our ranch near Plush Oregon a few weeks ago. It is the 2nd complete bone fossil I have ever found. The first was allegedly a camel cannon bone. I would like to make a post on it later but this one really grabs my attention. The length is 1 3/8" (34.925 mm) and the larger width is 1/2" (12.7 mm) and the smaller width is 3/8" (9.525 mm). I found it in a small dry alkaline lakebed. I have found fragments from there for a long time. People just call them camel bones but there has never been anything identifiable. The last picture is of the fragments you usually fi

    Clarno Wood Dig

    While out wandering with friends in Clarno vicinity (the town, but probably also the formation; well away from the Palisades and on public land open to rockhounding and collection,) we came across some really vibrant, bright petrified wood, quite unusual for the area. The source tree looks like it's encased in a coarse ash or tuff, with a "shell" of harder material. The wood looks agatized but is still very brittle, too brittle for lapidary application but gorgeous for display; lot of opalized areas and mineralization. I tried to get back far enough to get a solid round but was unsuccessful (r
  22. This was located approximately 20 miles from Lost Forest, Fossil lake area in SE Oregon on some property my folks own. Sorry the ruler isn't lined up better but you can get a good idea of the size. Any help identifying is appreciated. Thanks!

    Moolack Beach, OR - Possible Bone?

    Hi, Was down beachcombing Oregon after the recent storms and stopped at Moolack to look for fossils. I'm generally familiar with the bivalves and other invertebrate fossils that are present. However this particular specimen has me scratching my head. It appears to be in the same hard mudstone that most of the invertebrate fossils are in, however there are many grey look-alike rocks on the beach and this one has obviously been tumbled for a while with the other beach cobbles. It is about 4 inches (long axis), and 2x2 inches (short axis, on end). I've seen toredo wood, wh
  24. I think I've found my "home" here. I have well over 50 pieces (a couple are large - 10-25 pounds) of formation that I've collected over the last three months to "investigate". Mostly sandstone and what I think is deep water mudstone (thought it was shale at first but no layering). Will try the Hydrogen Peroxide to dissolve the sandstones but am at a loss for the mudstones. the mudstones are extremely hard but contain lots of micro deep water (>200 meters) fossils. Any advice? I've included an image in the what I think is a softer mudstone higher up in the Keasy. This is juvenile
