ID requested on possible petrified wood (maybe bone?) found in Tennessee Cumberland Plateau

[Rdwills]

Hello everyone. I recently moved to central Tennessee on the Cumberland Plateau where I have been enjoying hunting stone points in the creeks and woods. I recently found some chunks of what I thought might be petrified wood and would be grateful for ID help. Here are the details per the ID TIPS post:

 

Date: Found February 2023

Location: Van Buren County, Tennessee USA

Site details: bank of a small creek in close proximity to a spring

Found with: a few stone points and stone point fragments and some smaller pieces of possible bone or petrified wood

Dimensions: longest side approx. 79mm, width approx. 65mm, thickness approx. 45mm. 

Weight: 5 oz/142 grams

 

thanks for looking and for any help.

This looks like petrified wood to me.  It looks like it may have iron oxide on it, giving it a strange appearance in places and causing a lot of that rust color.

 

Compare to these examples.
