Benthic foraminiferal biostratigraphy of the Jurassic platform carbonate succession in the Bolkar Mountains (southern Turkey)

The stratigraphic distribution of benthic foraminiferal and dasycladacean algal taxa in the Jurassic platform carbonate succession of the Bolkar Mountains permitted to recognise five zoned and two subzones in the Jurassic (Bajocian to Tithonian), These are in ascending order: J1-Bosniella croatical/Riyadhella regularis zone (Bajocian); J2-Redmondoides Iugeoni/R. of. rotundatus zone (lower Bathonian) comprising J2a-Paravalvulina complicata subzone in its middle part; J3-Paleopfenderina trochoideal P. salernitana zone (upper Bathonian-Callovian) comprising J3a-Satorina apuliensis/Kilianina blancheti subzone in its lower part; J4-Kurnubia ex.gr. palastiniensis zone (Oxfordian-lower Kimmeridgian); J5-Clypeina jurassica zone (upper Kimmeridgian-Tithonian). This biostratigraphic scheme corresponds to those for the peri-Mediterranean Jurassic platforms, except for J2 zone and J2a subzone which are first time introduced from the Bolkar Mountains Jurassic succession.
