possible petrified palm nut

[jimm]

I found this at the Siskiyou Pass near the border of Oregon and California. It was in 2 pieces when I found it - that fit together. In this same area I found lots of petrified wood including petrified palm wood and other petrified wood both large and small. Could this be a petrified palm nut? The length of the 2 pieces together is over 15 centimeters and the diameter where it broke is over 6 centimeters.

I forgot to mention that it came from the Oregon Hornbrook Formation (Siskiyou Pass near the California border) -- 100-85 Ma

Saginite mineralization?

Just the cross section looks like palm wood of some sort. The only reason that I think that it isn't is the shape of the entire piece before being broken. It looks far too wide to be a palm nut.
