Here's a fossil tooth. I think it may be a prehistoric elephant of some type. I'm leaning toward Tetralophodon. Mastodon was suggested in the fossil forum, but i don't know...
The other is some sort of nodule, I guess. Thunderegg of some sort? Found about a dozen slabs at the bottom of a crate. Not primo, but kind of interesting. I think it could cab nicely:
Any thoughts are appreciated

WARNING: I'm definitely not an expert so take what my guesses are with a grain of salt That aside, I'd guess it's more of a partial mammoth molar shape. I looked at this post [ link] and saw that certain types of mammoth resemble the shape pretty well toward the narrower portion of the tooth. Also I'd guess that the ridges may be more or less connected depending on wear/how old the animal is. Maybe this will help get you to the right place even if it's wrong

The second photo might be a piece of wood.

The second one does sort of look like a thunderegg/geode. Looks like it has a rhyolite covering on it. At 12 o'clock (top, under your finger), and 3 o'clock (at the right side of the slab), you can see a tannish matrix at the "notches." Not typical red rhyolite, but could be rhyolite all the same. stephan , what does the outside of one of the balls look like? Oops, never mind. You said they were already slabbed. Maybe another one has a little more of that matrix?

Mastodon, have wider plate between crown points on the back molars. Now i only know the local Oregonians. Mammoth have closer crown points on the top.
Though the elephant teeth change do to feed & and what there is to be found.
Oregon last cave record is about 4700 Bp. time.
And they have 7 rows of new teeth in the gum line waiting to to replace the worn out ones, from grinding hard feed.

Maybe another one has a little more of that matrix? That's kind of what I was thinking... sort of a pale rhyolite. The edge of the slab if lumpy, almost like bark, further reinforcing that.
