What did araucaria species like Woodworthia resemble in life? Where can I find a good example of some paleoart reconstruction of one?

Additionally, how did the element chromium cause the fossil’s green colour?

Whoops, I was referring to artists who draw reconstructions of extinct organisms. I should have specified, sorry.

They were probably araucaria like most other tree species at the time.

Definitely not tree ferns or calamites.

The closest approximation we have to Triassic conifers we have around today are Monkey Puzzles trees. Having done a bunch of work in the Chinle, I also have a bunch of petrified wood from that time period.

Chromium causes the coloration that it does because of the available energy states of the atoms trapped within the crystalline matrix. when hit by EM waves, the valence electrons involved with the bonding will emit a photon of a certain proportional wavelength to maintain their most stable energy state.

What about possible tree ferns or cycads?
