中国非海相侏罗纪沉积中广泛记录有化石木，分布于9个省、18个地点。目前已记录的植物有17属33种，主要隶属于松柏目、苏铁目和本氏目。从地层学上看，化石木在下、中、上侏罗纪的不同层位之间变化;主要出现在Aalenian-Bajocian、Alonian-Calovian和Oxfordian-Tithonian层段。中国侏罗纪森林主要分布在北方植物区系省，而南方植物区系省则很少。植物多样性和解剖学特征，特别是生长轮特征的分析，揭示了北方植物区系区系早、中、晚侏罗世时期气候条件具有明显的季节变化。
Fossil woods are widely recorded in the non-marine Jurassic deposits of China from nine provinces and 18 localities. About 33 species referred to 17 genera have been documented, which are mainly ascribed to coniferales, cycadales and bennettitales. Stratigraphically, the fossil woods vary between a variety of horizons in the Lower, Middle and Upper Jurassic; the occurrences predominate in the Aalenian-Bajocian, Bathonian-Callovian and Oxfordian-Tithonian intervals. Jurassic woods are mainly distributed in the Northern Floristic Province in China, whereas they are rare in the Southern Floristic Province. Diversity and anatomical characteristics, especially the growth ring feature analysis implies climatic conditions with distinct seasonal variation in the Northern Floristic Province during the Early, Middle and Late Jurassic periods.
