In the area of the Central and NW Bohemia, Czech Republic, the fossil wood is quite abundant, found in different states of preservation and present from Paleozoic (Pennsylvanian), through Mesozoic (Upper Cretaceous), to Cenozoic (upper Eocene to lower Miocene). So, this small area is ideal to demonstrate various aspects of the fossil wood analyses, including anatomy (unifacial vs. bifacial cambium, formation of tyloses and its significance, early vs. late wood, unambiguity of scientific terminology, stem vs. root wood), taphonomy (completeness of fossil record, influence of environment on mode of preservation, influence of preservation on wood anatomy and preservation potential, discrepancy between the record of wood and other organs), systematics (stem vs. crown group, wide concept of fossil wood genera, "mosaic" species, wood of extinct plants), and palaeoclimatic reconstruction (definition of "wood type," subjective vs. objective methods). The majority of the studied woods were thin-sectioned following the standard techniques and observed with a compound light microscope.
在捷克共和国中波希米亚中部和西北部地区，化石木材相当丰富，从古生代（宾夕法尼亚纪）到中生代（上白垩纪），再到新生代（上始新世到下中新世）都有发现，保存状态各异。因此，这个小地区非常适合展示化石木材分析的各个方面，包括解剖学（单面 vs. 双面形成层、侵填体的形成及其意义、早材与晚材、科学术语的明确性、茎木与根木）、埋藏学（化石记录的完整性、环境对保存方式的影响、保存对木材解剖结构和保存潜力的影响、木材与其他器官记录之间的差异）、系统学（茎木与冠群、化石木材属的广泛概念、“镶嵌”物种、已灭绝植物的木材）和古气候重建（“木材类型”的定义、主观与客观方法）。研究中使用的大多数木材都是按照标准技术进行薄片制作，并使用复合显微镜进行观察。
