These magnifications are from a thin slab of silicified palm fossil. I wet sanded the slab with 320 and 800 grit paper. Karate Kid's Mr. Miyagi would be proud of my sanding work!
Fossil was photographed wet to enhance the contrast. Have not tried polishing it yet.
This fossil appears to be of the genus Palmoxylon and was found in Texas. It is from the Eocene.
Thanks to Herb for the fossil.
