An in situ late Miocene (Pannonian) fossil forest preserved as wood has been uncovered at Bükkábrány,
Hungary. Excavation within the open-pit mine revealed 16 stumps that ranged from 1.8 to 3.6 m in diameter
at the base and up to 6 m in height preserved atop a 16 m thick coal seam. A relative change in the elevation of
Lake Pannon appears to have drowned the forest about 7 Ma ago. Sand deposited as part of a prograding delta
covered the landscape and preserved the trunks in a waterlogged condition. Forest stand density was 36 stems
per hectare. The trees grew 3 to 16 m apart. Their diameter at breast height ranged from 137 to 248 cm. Stem
basal area varied from 3.46 to 8.44 m2 per tree, yielding a forest basal area of 240 m2/ha. The tree height was
probably 44 to 52 m and the stem volume ranged from 44 to 125 m3. The total biomass of 1400 t/ha is estimated
for the Miocene Bükkábrány forest. The net annual primary production was in the range of 2.8 t/ha.
