• outcrop-level geographic resolution
When: Sivik Formation, Middle Miocene (16.0 - 11.6 Ma)
• Vatsev and Pirumova (1983) identified the Sivik Formation as Middle-Late Miocene based on the diatomaceous floral composition of the sediments. Vatsev (1999) gave the age of the Sivik formation as Middle Miocene. Ognjanova-Rumenova (2003) determined the age of the top layers of the Sivik Formation through analysis of the diatom assemblages as late Miocene. Based on the total content of the macroflora from all the layers of this formation, Bozukov (2002) determined the age as Middle Miocene; this date was also confirmed by pollen analysis and is adopted here (Ivanov, 2004, 2012, 2013). Since the fossil insects were not from the upper part of the Sivik Formation, their age should be considered as Middle Miocene.
