Upper member Bidahochi Formation, 5 Ma

[Knickpoint]

Thanks for looking.  I found this bone as float from a gravel deposit in northeastern AZ, part of the Bidahochi Formation.  Could be from the deposit itself, 5 Ma, or eroded into the formation from Triassic bedrock.  
 

 

 

 

Thanks again!

Looks like a phalanx bone to me.

Is it light, or is it fossilized?

I’d say fossilized,
