I looked for an old post because I think I looked for info about Cycad fossils before... Anyway, here are some pictures. Please let me know if you have any idea what these are. Or if they are not Cycad cones. Most pieces are 1 to 2 inches across. thanks again

Those do look like some pieces we've gotten from our club's raffle table at the meetings. Obviously not a source for top-quality specimens since they're donated bits, so we don't have anything that looks like your first photo.
The shape and color of the others is similar to what we have.

Definitely outside my normal wheelhouse although I love petrified cones for their structure. I guess my question would be the core of the cone. Are Cycad cones that different from all other cones in that there is no core? Again if Cycad cones are solid fibers then that would explain it. In searching the web for Cycad cones I didn't find any that resembled it. I looked for an example in my book of petrified woods and it does have an image of an uncut specimen, which I might add looks a lot like your upper left example it did not have any cut views. It's a pity I don't have Walt Wrights Email as he could lend very considerable knowledge to the question where I can not.

The American Sycamore is a common tree that has round balls of feathery seeds slightly larger than a quarter. Guess I will chase that for awhile.
