The Early Cretaceous (Bucovinian Nappe) deposits have been mapped only on the external flank of the Rarău Syncline, where they form a coarse clastic succession (breccias, conglomerates and sandstones) with very poor fauna. New paleontological data are added through the present paper, the most important regarding the Tethyan ammonite Olcostephanus (Olcostephanus) guebhardti (KILIAN, 1902). This is the second species quoted in the “Muncelu Sandstone and Conglomerate” which can be used to confirm the age of the studied beds. Several observations concerning the breccias and their relation to the subjacent and suprajacent layers are also made.
