Found a large boulder that had recently tumbled down a rocky hillside on a rock hounding trip near Elma Washington. The boulder measured about 4 x 4 x 3 ft. and consisted of compacted fine-grained sandstone or siltstone. However, there was a dark seam running through it. On closer inspection this darker material was encased in the fine sediment and looked like cells. We estimated this cell material made up around 30 percent of the rock structure. The seam expanded in certain areas. Here is a crude drawing. We used a rock hammer to break off a small chunk. The rock was very hard, and it took quite the effort to collect that small sample The small sample we collected weighed a little over 1 lb. So, the rock boulder would have roughly weighed 500 or more pounds. Bringing the sample home, I cut a small piece and then polished it using a lap. The material polishes up nicely and looks like cells. About a month later we brought a rock club to the site and the rock was gone! It had to have weighed hundreds of pounds yet there was no trace of the boulder. The group did find some small gastropods, so the trip was worth it—but what happened to the boulder and what is the material we collected. The site is in the Lincoln Creek Formation about 38 to 16 million years old and is at a high elevation.

I found this in an area near my home earlier tonight, that is full of concretions, and fossil snails, clams, crabs, etc. I believe that it's either a Great White, or a Megalodon tooth. I think that it's a megalodon! It's roughly 2 11/16" from top to bottom, and 2. 1/8" wide, at it's widest point. Just looking for information? Thank you.

Found this in a ditch in porter Washington. I think it could be bone. Is the brown on the outside some kind of skin and is the middle bone marrow? Would appreciate any information. Thank you
