Petrified ? with silicates ? ID needed

It is a petrified wood piece. You're correct that the replacement is with silica. Most fossil wood is preserved with some silica polymorph (minerals with the same chemical composition but different crystalline structure).

It is a piece of petrified wood that is likely silicified.

More precise identification involves specialized

expertise and technique as the below paers indicate.

 

Silicified wood is common in parts of Alabama and Mississippi.

I do not have references for Alabama, but some references

for Mississippi are:
