%X Species discrimination by charcoal analysis is possible, because the wood anatomical structure remains almost intact after carbonization process. Studies in this area are rare and directed to paleoecology and paleoetnobotany. Thus, this study aimed to characterize anatomically the carbonized wood of Copaifera cf. langsdorfii Desf. and Dipteryx odorata (Aubl.) Wild., proceeding from north region of Mato Grosso state, in order to provide information to manage its illegal commerce. From each species were carbonized ten samples with dimensions of 2 x 2 x 5 cm in muffle furnace, in stage program and highest temperature of 450¡ãC for 30 minutes, for seven hours. Final temperature applied does not change anatomical structure from both species, allowing its differentiation. The crystals formatremained without alterations, being visible little split.
