Dating Late Pleistocene Missoula Floods (Channel Scablands, Oregon, Washington)
Oxytropidoceras posted a topic in Geology
Below is a great lecture about dating the Missoula floods and the Channel Scablands that they created. Dating the Ice Age Floods Nick Zentner, Central Washington University CWU's Nick Zentner presents 'Dating the Ice Age Floods' - the 22nd talk in his ongoing Downtown Geology Lecture Series. Recorded at Hal Holmes Center on March 7, 2018 in Ellensburg, Washington, USA. Yours, Paul H. -
Greetings! I am completely new to fossil collecting but adore Keichousaurus and have spent a lot of time combing through old Fossil Forum posts about authenticating and preparing these fossils. Looking forward to learning more and hopefully finding some gorgeous specimens!

I am working on some fossil mounts as gifts and was wondering if anyone could help me Id or had an idea of what these leaves are. The first two are the same kind of leaf I believe. The two taken without the ruler: image three 2 inches, Image four 2 1/2 inches! These all come from around Burns in Eastern, Oregon. A HUGE thank you! Nyla

Hi all. I was was hoping to get help with this one from the community. It was found in-stream near an outcropping of Pittsburg Bluff in Clatsop County, Oregon, and downstream of some Astoria Formation, both marine sediments. I have found mollusks and arthropods in the same collecting area, usually in very hard concretions. To my knowledge no marine vertebrate fossils have been found within the Pittsburg Bluff Group so if it is vertebrate I'm thinking it came down from the Astoria Formation southwest of the area. It looks and feels like bone, and is extremely porous (tongue sticks). Or it may just be a pseudofossil. Either way, thank you for the help.

What I believe to be a carpus of the major chela of a ghost shrimp. Not an unusual find for me, but this was found near an exposure of Pittsburgh Bluff formation where previously I have only found them in Astoria formation.

Missoula Floods might have been 80 percent smaller than currently estimated

I was on the Oregon coast near Newport and found this really odd looking rock. I've scoured the internet and have seen nothing like it. Even the Google image search feature came up with nothing. Help!!!

Any Ideas on this?

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. My personal favorite, a Macoma with a nice golden luster, all mounted up. M I was hoping to find a cetacean vert, but I was only there for a few hours, so I didn't put the time in that it would likely require to find such a thing. I was stoked to find such stellar bivalves, but I wanted to come home with something other than just clams. A shop in Lincoln City afforded me that opportunity, and after dropping $30, I got my hands on a nice Dichocrinus from Carboniferous Iowa. In Lincoln I also found a dead Pacific mole crab, Emerita analoga, which I think makes a great wet specimen.

Hello, I found some fossil teeth on a friends ranch in Eastern Oregon and was hoping for some help with ID. The area has been described as Mascall Formation (16 Ma) from the Miocene, however there aren't any detailed geologic maps of the region and I suspect some areas may be closer to the Pliocene. The teeth were found as float material from several places. I think #1 or #2 may be Merychippus or Pliohippus (horses) and #4 may be Equus (horse). #1-3 were all found in the same general area and I am fairly confident it is Mascall Fm (Miocene). However, #4 was found in another area and appears to be Equus. Since Equus is from the Pliocene, I am thinking it could be from the younger (Pliocene) Rattlesnake Fm or an undescribed strata. I am a little more unsure about #3 and think I could be a rhino or similar large mammal. Thank you for your help,

Astoria Formation Fossils From Oregon Coast
RainBoKatchr posted a topic in General Fossil Discussion
I have been an avid collector of Astoria Formation fossils from the Oregon coast for a number of years, and plan on putting up a web page that shows every known invertebrate species from the Newportian stage of the Astoria formation (plus as many vertebrate and plant species as possible). In my collection I am still short by a dozen or so invertebrate species out of the nearly-100 described in the literature, although I have also found a dozen or so that AREN'T in the literature, and plan on describing and naming them if they are indeed "new" species. So I was wondering if there were any fellow collectors that have unusual stuff that they could share photos of. One of my recent finds was a conifer cone (shown below), although I don't know what genus and species it belongs to (does anybody know?).

Hello! New to the forum here as I have some young fossil enthusiasts at home. We just returned from a trip to E. Oregon where my kids were hunting for fossils in an area known for mammal fossils. Can anyone tell me if they think this is a modern bone or a fossil? It seems to have stone fused in the middle and feels slightly heavier than a regular animal bone.

I have a couple fossils that I thought could were petrified wood. I found them around 15-20 years ago near sunset bay on the Southern Oregon Coast. They were both loose on the ground. My friend thinks that they look more like bone than wood, any thoughts? Thank you

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!

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?

New guy from the Oregon Coast! Hello all!
Oregon Coast Agates posted a topic in Member Introductions
Hello all! My name is Eric and I've come here to learn more about fossil finds specific to my region, The Oregon Coast. I do not claim to be an expert in this area but I love rockhounding (specifically agate hunting) but have developed a love for fossils as well. I'm fascinated by the things that wash up on our shoreline and discovering the amazing history in this area. I would love to get some help identifying some of the things we find along our coast, and potentially offer insight to other on some of the marine fossils I am familiar with. Thanks!- 8 replies

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…

All of these came from Oregon or Washington State. My kids tell me they're just rocks... I know for sure that quite a few of them are more then just plain rocks ..right?

Hello, I’ve been picking up beautiful agates and hunting rocks my whole life and just recently really got interested in learning the names and properties of rocks and gems. Looking for all the help I can get on the best books to help identify rocks and minerals Etc as well as help with identifying a few pieces I’ve found on the beach. Happy to have found this site as I believe I can also absorb some knowledge just by listening to the discussions going on on the boards.
