Abstract :
This paper presents first a discussion on the status of the subdivisions of the European Neogene mammal chronology and second, it synthesizes all available magnetostratigraphic data from Europe to provide chronological framework for mammal localities, mammalian events and mammalian biochronologic units of the European Neogene. e of the lack of their rock equivalents, the subdivisions of the European Neogene, based on mammals, have not attained the stage status in terms of reliability, except the Vallesian and Turolian. Therefore they are designated as the European Land Mammal Ages (ELMA). ostratigraphic data on mammal-bearing deposits in Europe is still scarce in time and space; consequently, it is not yet possible to correlate accurately all ELMA and MN zones with the geomagnetic polarity time-scale (GPTS). Nevertheless, several studies dealing with mammal localities (and their deposits) around the Oligocene/Miocene boundary, in the middle and late Miocene provide reliable correlations of some ELMA and MN zone boundaries. Thus, the calibration of the Oligocene/Miocene boundary at the base of Chron C6Cn.2n is in agreement with its age in marine deposits. The well-known Hipparion Datum (Astaracian/Vallesian boundary) is now dated as about 10.8 Ma, occurring slightly above the base of Chron C5n.2n. aper also reviews magnetostratigraphic correlations of some late Miocene and Pliocene mammal localities in the Paratethys area. Taking into account the chronological assessments in other parts of Europe for some key mammalian events, new correlations with the GPTS have been proposed for these localities. Thus some new ages are suggested for the late Miocene and Pliocene Paratethys stages.
