Jerry W. Posted February 28, 2020 Share Posted February 28, 2020 Some petrified wood found in northwestern New Mexico, San Juan Basin, Upper Cretaceous, Kirtland Formation a couple of weeks ago. The cut slabs are from a log about 6-inches in diameter and my best guess is conifer only because most everything else in that area turns out to be conifer, specifically, Cupressinoxylon sp. Any other opinion about species would be welcome. There are several nice agate bands running through the length of the log and are clearly visible here. The first slab is dry and the second is wet. 2 Link to post Share on other sites
Tidgy's Dad Posted February 28, 2020 Share Posted February 28, 2020 Very nice and I love the blue agate bands too. Link to post Share on other sites
FossilNerd Posted February 28, 2020 Share Posted February 28, 2020 I can’t confirm or deny conifer, but that is a beautiful piece. Love the banding! Link to post Share on other sites

Rockwood Posted February 29, 2020 Share Posted February 29, 2020 Can you show us a surface that represents a transverse section ? Link to post Share on other sites

Here is a longitudinal shot of the complete collected specimen showing the dissected portion. Unfortunately, no bark from the wood was also fossilized. From studies of that area (about 10 miles away), there was once a conifer forest close by enveloped by a bog or swamp. Such a thing would ordinarily rid the submerged trees of their outer bark.

Tidgy's Dad Posted March 1, 2020 Share Posted March 1, 2020 I think @Rockwood has quoted @Moozillion's post and then deleted everything except the part of @Jerry W.'s post that he wished to quote. But he didn't realize it would leave the time and poster listed as being Bea's (Moozillion's). 2 Link to post Share on other sites

I'm glad I'm not the only one who makes computer errors! If only these dang machines would do what I WANT instead of what I TELL them to do!!! Link to post Share on other sites

Commenting on the genus/species is not really possible with only macroscopic images. In fact, based on the photographs you present here alone, one wouldn't be able to conclusively confirm you're dealing with a softwood. You may be able to get further on your own, using a hand lens and comparing the wood microstructure to reference materials, like the InsideWood database: https://insidewood.lib.ncsu.edu/search.
