I have found a piece of petrified wood that I have ID'd as Paraphyllanthoxylon, thought to be a large common tree during the tropical Cretaceous.  Very near it, I found a piece of petrified wood that is from the genus Quercus, very modern looking.  the two shouldn't be found together as I understand their temporal distribution.

 

Does anybody have a time range for when Paraphyllathoxylon is thought to have existed?  I can't find an age range in any of the literature I have looked through (far from an exhaustive search).

The range is Cretaceous - Miocene-Pliocene.
