The highly porous material offers a large and protected surface area for microbial colonization.Original article: www.researchgate.net/publication/236896931_641_-_Biotreat...Above image shows a pumice stone (note 1), which is a volcanic rock.The pumice stone was made up of numerous fossilized wood cells (note 2), some of which are marked with red arrows/red lines.Red arrows point to transversal sections of wood cells. Red lines mark longitudinal sections of wood cells (mostly wood fibers).For comparison with recent plant fibers and vessel elements, see www.flickr.com/photos/fossil_lin/54353883128/in/dateposte...Another example: wretchfossil.blogspot.com/2025/03/wood-cell-remains-in-pu...Note 1: Wikipedia article on pumice: en.wikipedia.org/wiki/PumiceNote 2: an album on Wood Cells on Earth: www.flickr.com/photos/fossil_lin/albums/72177720296071690Added on May 17, 2025: Vessel elements on Earth range from 15 to 800 micrometers in diameter, according to ChatGPT 4o.An album regarding Wood Cells on Earth: www.flickr.com/photos/fossil_lin/albums/72177720296071690An album regarding Wood Cells from Mars: www.flickr.com/photos/fossil_lin/albums/72177720309621950 |
