Measurements: 150 x 108 x 11 mm
Description: An interesting slab of (?)petrified wood, sliced and polished on one side.
We bought this piece along with a batch of other mineral specimens, and are not sure what it is, or from where it originates.
A tiny piece (8 mm in diametre) of the upper edge is loose, and we tried to dislodge it, but it only wiggles. Forcing it may cause damage to the rest, so we left it. Thinking of a clock, it lies between 1 o'clock and 2 o'clock if you look at the first image.
