The studied material is represented by 8 pieces of silicified wood, four of them found in the Cristian area, on the Fabricii valley, and four in the Holbav area, on the Maiului brook, in the Lower Jurassic continental deposits with pyroclastic character considered of Sinemurian- Pliensbachian age, most probably Pliensbachian. All the studied samples are trunk or thick-branch fragments, having decimetric size, dark to black color and, by magnifying glass or even by naked eye, regular fibrous structure without vessels can be seen, clearly suggesting a conifer wood. The specimens having field-numbers: 1015, 1016Cr, 1018Cr, 1019Cr, 1020Cr, 1027, 1042, 1043 belong to "Grădinaru Collection", and are deposited now in the collections of the Geological Institute of

The interradial bundles have 1-10(12) radial regular rows of tracheids and density is 992- 1444(1518) tracheids per mm2. Tangentially seen the tracheids are usually unpitted, or rarely pitted (in specimen 1019) with small round pits (d=8-12 μm) with small apertures (d=4-5 μm), in a single row arranged, slightly irregular, locally as two opposite pits.

In fact, generally, the pitted areas don't cover integrally the tracheidal wall. The pits have round borders of 18-22 often flattened when contiguous (d/D=0.65-0.88), and round or tilted to lying elliptic apertures of 7.5-10/2-3 μm (in specimen 1019). None crassulae or helical thickenings have been seen, but sometimes a brown content is present

It has relatively thin vertical walls relatively similar to those of the tracheids and sometimes with simple pits, irregularly arranged on 1-2 rows. The horizontal (terminal) walls are thin and smooth or slightly nodular and, inside the cells, resin content or plugs or granules, and sometimes small polygonal crystals are present (specimens 1015, 1019).
