Abstract:The cuticular features important for identification and classification of fossil plants, and they are also helpful to reconstruct palaeoclimate during geological history. How to better obtain the characteristics of cuticle features for the fossil plants with cuticles, which is especially important to choose the appropriate experimental technology. In this paper, three different methods 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 coalbed or coal-accumulating period, and the HNO3 maceration method is suitable for the fossil plants in gray-white or diatomite mudstone. This study summarizes the effects of three methods to fossil plant cuticles in different geological ages, and aims to provide more effective experimental approaches for studying the cuticular features of fossil plants.
