Veres János: A bükkábrányi 8 millió éves mocsárerdő (Múzeumi Mozaik 7. Miskolc, 2007)

chemical, biologic, or physical activity which affects the remains of the organism. How these remains of the bisophere, living organisms become particals of the litosphere, the world of fossils. There are number of examples of fossilisation in local paleobotanical and archeological records. For instance the 20 million­year old special fossil remains of footprints and tree trunks of Ipolytarnóc. There was a same kind of expectation in Bükkábrány as well so the awe that followed can easily be imagined when not the anticipated fossilized tree remains but instead the real tree trunks were uncovered. Taphonomy studies post-mortem processes but other circumstances have to be taken into account too like to biostratinomy of the place that had been present there well before the burial. The variation in the age of trees, young sapplings, dying old decayed tree trunks, drift wood, tree stumps, ground growth, pollens, wildlife perhaps. In other words all the effects that had happened in the forest in its existance before its burial. Normally the process of fossilization or fossil diagenesis begins immediatelly after burial and conception of the biosphere into the litosphere. This very process has never occured in Bükkábrány the absence of which allows us to get a much clearer picture and defying the forces that shaped this region in geological history. For starters perhaps, lets see a few examples of how fossils of ancient organisms remain through the processes of taphonomy. The most common is fossil diagenesis which is basically the foundamental complexity of all the processes that occure after burial. In cases there are some extreme chemical­biological ones that may result in drastic taphonomical changes and unique preservation. Sometimes water assumes a significant role in these like in the case of Bükkábrány. The abundance or lack of water can, in fact, cause extreme processes in preservation. Examples are the mummification process in really dry environments or the aenerob processes in airtight,
