I found lots of petrified wood in the lower part of the Miocene Chalk Canyon Formation north of Phoenix. The layer is mostly sandy and pumaceous. Does anyone know what the siliceous 1mm long elongated spheres are or how they formed? Could they be fecal pellets, fungi or other fossils. I have seen similar structures associated with California Miocene palm wood. @paleoflor

 

Penny is 19 mm across.

My goal is to leave no stone or fossil unturned.

Ran across this from TFF,  sorry I didn't know how to link to the post.  It's about termite coprolite,  eggs and termite balls, fungi that mimick eggs. Just a thought.

Thanks, I saw the same FF post. I did not see any pellets that were hexagonal on my piece. 
 

I wonder if this could be petrified lichen. They are hard.

Are you quite certain you haven't already answered the question ?

Hi, sorry so late chiming in. This is the first time in a long time I've had a chance to sit down and look at poop. I would say those are fecal pellets. A while back I spent a lot of time looking at rotten wood under the microscope in order to try to identify which type of critters left which type of pellets. Those look a lot like millipede poop. These donations were made by a lovely smoky ghost millipede named Bertha (R.I.P.) She would leave piles of them on and beneath the wood she was eating.
