Looks like a cross section of a fossil sponge or coral. I have one similar, but darker in color.

It came from Central Oregon the slab is 12" by 11", the slab was cut off a 50# piece, interesting that it starts at a 12" size on the bottom and goes to a cone like point similar to some Tempskya I have, yet there is no cell structure of wood or fern that I can find under the scope....I couldn't find anyone at the Quartzsite or Tucson shows that could ID it......ratzzzz

Hmmm. I usually think of Central Oregon as wood country, not dino or marine fossil country but Oregon was covered by the sea in the mesozoic. There is a possibility that this is wood that was mostly decomposed before it was agatized like a lot of our south Texas wood is. As such, it's more of a cast and shows little if any remaining internal structure. Some of our Texas stuff has bark/wood patterns on the outside but internally, is simply unconsolidated moss or other agate or jasper. No wood grain or other structure visible at all. It could be a coral or sponge too I suppose as I can't see what the intact exterior would look like but it still as kind of a woody look to me. Was it found in a marine sediment area of Oregon or in one of the wood areas? I suppose that would be the determining factor to consider ....Mel

It seems to radiate out from the center eye. Fern is a possibility.

I'll post a picture of the intact end tomorrow, maybe that would help, Thanks for the input and with all your help the answer is hopefully close.....

Yup, looks like a sponge. And man, what a monster.

Well now that is as good an identification as I've heard about this thing, never could figure out what the outside represented, it makes sense now....thanks so much for the input. Not sure if I'll leave as a specimen now or cut it up....what would you all do?

You know, the fossil does look like a huge stovepipe sponge in those last pics and some sponges have a lot of calcium and silica on their skeletons so would fossilize well.
