Petrified Wood, (Pullisilvaxylon)?

[SPrice]

Not knowing petrified Wood species well, I searched the web and specifically TFF and came upon Marco Sr.'s fabulous thread and collection of pet.wood. 

 

I only have a few pieces and all are close enough in appearance to be the same species, if I'm guessing correctly.  And that would be Pullisilvaxylon arizonicum.

Anyone have a confirmation or another correct species?

Thanks, Steve

 

I cut 3 or 4 slabs off and gave the large piece to my son. He moved into a house his uncle bought for the college kiddos to be  closer the University and left it behind so I snagged it for the pics and ID.

The below quote is from a webpage (see below link) of the National Park Service for Petrified Forest National Park in Arizona:

 

 

"The park paleontologist comments that every single log would have to be thin sectioned and that sample examined microscopically to determine its genus and species as you just can’t tell with the naked eye. Identification of the tree species requires microscopic examination of thin sections of the xylem tissue. Based solely on the xylem structure of permineralized wood (including resin canals, rays and tracheid pitting), and without seed cones or DNA evidence, it is difficult to be certain which trees in the park are related to what living trees in our world. Some have suggested that the name “Agathoxylon” be used, but eventually that name will experience the same issues as Araucarioxylon."

Unfortunately, the above quote makes the point that petrified wood can't be accurately identified from life-size pictures.
