High temperature electron spin dynamics in the organic superconductor (TMTSF)2ClO4 (tetramethyltetraselenafulvalenium-perchlorate) was studied by means of EPR measurements. Distinct temperature dependencies were observed from the line components attributed to the highly conductive stacking direction and the transverse plane, respectively. In particular, while the stacking direction component shows a metallic behavior in the whole temperature range investigated, the other component shows an apparent dimensional crossover at around 160 K.
