AB Microcodium is a calcitic microfeature, mainly interpreted as root calcification products of terrestrialplants on carbonate-rich substrates, that is abundant in Paleogene successions of the peri-Tethyan realm.In the Betic Cordillera most of Microcodium appears as reworked in calcarenites interbedded in pelagicsedimentary rocks. In this study we analyse outcrops with in situ Microcodium aggregates located inSierra de la Pila (Internal Prebetic, Murcia province). Microcodium appears on top of Lutetian (MiddleEocene) platform limestones and shows: 1) cylindrical morphologies showing «corncob» colonieslongitudinally, and «rosette» structures in transverse section, and 2) individual or plural globularmorphologies, similar to «rosettes» in section. Microcodium is interpreted as developed in calcic paleosols,related with a seasonal semiarid climate, before the boundary Middle-Upper Eocene and the importantclimatic change marked with the beginning of the transition from the extreme global warmth of the earlyEocene «greenhouse « climate to the present glaciated state
