SYSTEMATICS AND BIOSTRATIGRAPHY OF THE PONTIAN CANDONIDAE (OSTRACODA) FROM THE EASTERN BLACK SEA REGION (NORTHERN TURKEY)

Year, pages: 2003, 21 - 40

In this study, 33 species (ten subgenera and one indet. subgenus) of Candonidae have been taxonomically determined from the eastern Black Sea region of Turkey. These are Candona, Caspiolla, Caspiocypris, Pontoniella, Bakunella, Lineocypris, Reticulocandona, Typhlocypris, Metacandona and indet subgenus. Five species are described as new namely: Candona (Caspiolla) ataensis, Candona (Pontoniella) turcica, Candona (Lineocypris) bafraensis, Candona (Caspiocypris) trabzonensis, Candona (Reticulocandona) stanchevae. Candona and its subgenera are dominant fossils in the sedimentary record of the Eastern Black Sea during the Pontian. These localities could be described as the "Candona Sea" due to this fact. The “Candona Sea” extended along the North Anatolian coast from the Sinop Peninsula to the Trabzon (Arakli) area during the whole Pontian and contains few endemic species. On the basis on the environmental properties of Candona and the other identified Ostracoda species, this aquatic environment could have had oligohaline (0.5–5 ‰) and mesohaline (5–18 ‰) salinity conditions in Pontian. This “Candona Sea” was located on the southern border of Paratethys bioprovince and it has connections directly with Pontian, Euxinian and Caspian Basin bioprovinces during this time interval.
