I have a 4" x 6" x 0.6" slab, collected in Arizona or New Mexico by my grandfather in the 1960s. It was cut and polished, now a pen holder. I can clearly see the cellular structure. Is it possible to determine the type of plant/tree this was? I can do this for living trees, but I'm lost with trees from millions of years ago. Also, there are some microscopic features that appear to be roots that were growing through the wood before silicification. Any thoughts or comments on these? See bottom left of 4th photo. Finally, are there are resources I can use to answer these questions? Researchers, experts, etc whom I might contact? Thanks for your help.

Trying to get input on this form I found in sediments from the Calvert Formation. This test batch is from a mudstone, broken up and reduced through no. 20 and no.120 testing sieves. The close up is using a 40/0.65 lens
