结果总结和正在进行的进一步研究。在布克布拉尼出土了7马化石林，以木材的形式保存下来。由于潘农湖水位突然上升，淹没了森林，并将其掩埋在三角洲的砂体中，因此得以保存。水的饱和持续了700万年，使得木质材料得以保存，矿物沉淀最少。作为地球上已知的以木材形式保存的最古老的森林，布克布拉尼化石森林值得专门研究，概述如下。•植物化石的分类：木材（Martina D OLEZYCH），叶区系（Lilla H able, Boglarka E RDEI），花粉区系（enikerm AGYARI）•树木年代学-树木的年龄，它们的相对年龄，古环境变化（气候，季节性，干旱，洪水），森林结构：树木的尺寸，社会结构，与最近的森林比较（Miklos K AZMER）。•环境变化的碳同位素记录(Boglarka E
Summary of results and further studies in progress An approx. 7 Ma fossil forest has been excavated at Bukkabrany, preserved as wood. Preservation was made possible due to a sudden rise of level of Lake Pannon, drowning the forest and burying it by the sand body of a delta. Water saturation lasting for 7 million years allowed preservation of woody material, with minimum of mineral precipitation. Being the oldest known forest on Earth preserved as wood, the Bukkabrany fossil forest deserves special study, outlined as follows. • Age of the coal bed and forest (Imre M AGYAR ) • Taxonomy of plant fossils: wood (Martina D OLEZYCH ), leaf flora (Lilla H ABLY , Boglarka E RDEI ), pollen flora (Enikő M AGYARI ) • Dendrochronology – age of the trees, their relative age, palaeoenvironmental changes (climate, seasonality, aridity, flooding), forest structure: dimensions of trees, social structure, comparison with recent forests (Miklos K AZMER ). • Carbon isotope record of environmental change (Boglarka E
