    This study summarizes the final results of magnetostratigraphic and biostratigraphical investigations of the Tithonian/Berriasian boundary (J/K) limestones at the locality of Puerto Escaño, Spain. Suitable physical properties of the limestones studied, a favourable geological setting and rich microfossil assemblages (calpionellids and ammonites) at Puerto Escaño (magnetozones M20r to M18n) allowed a systematic collection of new data from the original synoptic section, which now has the character of a high-resolution profile across the J/K boundary. Two reverse subzones detected within magnetozones M20n and M19n are named the ‘Kysuca Subzone’ and ‘Brodno Subzone’, respectively. The positions of the individual events of tintinnoid biostratigraphy (mainly calpionellids) relative to the global magnetic polarity timescale are precisely defined.
