Abstract:The cuticular features are important for identification and classification of fossil plants, and also helpful in reconstructing palaeoclimate during geological history. It is important to choose the appropriate experimental technology for obtaining better characteristics of cuticle features for the fossil plants with cuticles. In this paper three different methods namely Aqua regia and NaClO maceration method, NaClO maceration method, and HNO3 maceration method were used to obtain cuticles from fossil plants of different geological ages. The results show that the Aqua regia and NaClO maceration method is suitable for the fossil plants in sandy mudstone. The NaClO maceration method is suitable for the fossil plants in mudstone of coal bed or coal- accumulating period, and the HNO3 maceration method is suitable for the fossil plants in gray- white or diatomite mudstone. The three kinds of maceration methods used in this paper can either be selected according to the specific conditions of fossil materials in the study of plant cuticles or all three methods can be tried at the same time to obtain the best experimental results. This study summarizes the effect of three methods on fossil plant cuticles in different geological ages, and aims to provide an effective experimental approach to studying the cuticular features of fossil plants.
