I found this on the beach of the puget sound near a very high eroding bluff. It’s about 2 inches in diameter, with a distinct center and spiral shape. Does anyone have any ideas about what it might be?

A few odds and ends I picked up on Sunday from Twin Beach, Washington. The Burke Museum Paleontology Database is still down (PLEASE BURKE, GET IT BACK ONLINE!!!), so I can't really ID the snails right now, but one of them is clearly a moon snail, and if I had to hazard a guess, the big one is maybe some sort of spindle snail? Prepping it was very easy and zen. And of course a Callianopsis clallamensis ghost shrimp that the beach is so well known for. Till' next time!

Hello all! In my hunt to find crab concretions I started out at the beaches of the Olympic Peninsula. I wanted to share what I have found! I have gone three times so far and the close to six hour round trip was a bit rough, but very well worth it and I can't wait to learn and discover more. I am struggling to find crabs, but I am continuing my research and hope to figure something out soon. If there is anyone that could point me in the right direction that would be greatly appriciated as well! The first concretion I opened, It took no effort to crack. I speculate it could be a piece of bone? Wood? A super lucky find, I cracked this open after returning home and found leaf fossil concretion! I believe that these are not common on the olymipic peninsula?? I think they are Oak? Quercus? I believe a bivalve? I was confused with this one, could this be a parital crab carapace? Or the shell of a snail? And lastly this claw. Is it shrimp or crab?

Can anyone recommend sources for identifying fossils we find on Murdock Beach on the Olympic Peninsula, Washington? Thank you.

This fossil was found yesterday on Murdock Beach, Olympic Peninsula, Washington. It is about 1" x 2". We've been there many times but never found anything like this before. Actually, my kids found many fossils that weren't typical of what we 'usually' find. Any help with identifying it would be much appreciated. Thank you.

Weather was pretty decent Monday-Tuesday, so I thought a trip back out to the Peninsula would be nice. Twin Beach is good place to find marine Oligocene fossils. I read a paper recently that proposes that the fossils here may have been part of a 300+ meter deep sea shelf community that was slowly uplifted. Callianopsis clallamensis ghost shrimp claws, extremely common here. Regret cracking this one, would have looked really good prepped. Many of the shrimp fossils have calcite crystals that have formed inside them. Lucina hannibali clams, next to the trace fossil shrimp burrows, probably the most common fossil at the beach. A Lirracassis sea snail! But obviously it either weathered out or someone beat me to it. Luckily I found my own! Here it is after I prepped it out. I'm really new to prepping, but I think it turned out pretty well. I think I used too much paraloid, it's a little shinier than I would have liked.

Hello, I am a newbie here and hoping to get some help IDing some what I believe to be fossils I found at Murdock and the Twin Rivers beaches (both are along the strait of Juan de Fuca coastline). These beaches are well known for having lots of concretion fossils. From what I’ve heard lot of sand shrimp, clams, and sometimes even whale or other mammal bones. Pic 1 &2:I think this giant rock is a fossilized whale vertebrae... I had one other person who is a fossil expert say that but looking for second opinions. Pic 3: Smaller fossilized bone? Pic 4 &6: my biggest interesting mystery!! Is this fossilized kelp, Crinoid or something else???? Pic 5& 9: curious what the cylinder long fossils are... many of them are hollow in the middle and have calcite/quartz crystals inside. I read another persons post about those strange tubes possibly being burrow tubes for mud shrimp. I originally thought crinoid stems or kelp tubes. Thoughts? Pic 7: Just a nice example of a concretion with a claw (crab or shrimp) round in this area Pic 8: Sea slug? I have no idea... Pic 10 & 11: Again I am wondering if it is a bone (my initial reaction) or if it’s fossilized kelp? Thoughts? Thank you for any help you can provide! I am teaching my sons who I homeschool along with myself as we get more into rockhounding and fossil hunting! -Holly

Hi all! I am completely new to fossil collection, and have started it only because I had an assignment for a class. Now, however,after visiting couple of fossil sites and getting pictures of what I found, I got excited and curious. I searched internet but only get lost. So my main question is whether at least one of my finds is a fossil, or all of them are rocks? Pictures and information about location below. 1. Alki Point, Seattle. Found it in a shale. About 3 cm long 2. Alki Point, Seattle. Found it in shale. White rings in shale about 3 mm in diameter: 3. West coast of Olympic Peninsula,WA found it on the beach near Cape Alava 4 cm wide, 2.5 high 4. Find it near Clallam Bay, WA. 6 cm long, 3 high

Hello, I am a rank amateur in the field of geology, but have a bit more than a passing interest. I stumbled across this forum after a google search for concretion images sparked by a friends posting of a find in Hawaii.
