This paper deals with the preparation of cuticles of Paleozoic plants and has two main objectives: 1) Summarize the conventional techniques, responding to the increasing interest shown by South American paleobotanists in the study of cuticles of fossil plants; 2) Present some unconventional aspects of these techniques, according to our own experience in studying cuticles of Lower Permian fossil plants of the Parana Basin. This is useful, as the preparation of cuticles, especially those found in Paleozoic sediments, presents various particularities according to the diagenetic and postdiagenetic conditions to which the cuticle was exposed.
