The Neogene Alibonca, Küseyin, Parçikan, Boyaca formations and the Mamaar volcanic unit occur at Arguvan (Malatya, Eastern Anatolia). Nine species of ostracods were identified and assigned to four genera in samples collected from the Küseyin and Parçikan formations. The faunal content in these units was characterized by few ostracod species and abundant individuals. Most samples contained fewer than nine species. Ilyocypris bradyi, Ilyocypris gibba, Candona parallela pannonica and Heterocypris salina are described in the Küseyin Formation. Cyprideis pannonica, Cyprideis anatolica, Cyprideis torosa, Ilyocypris gibba, Candona angulata, Candona neglecta, Candona parallela pannonica and Heterocypris salina are described in Parçikan Formation. Cyprideis, which has ecophenotypic ornamentations (smooth, punctuated, reticulated or nodes), is the dominant genus in the Parçikan Formation. Lithological features and fossil contents of the Upper Miocene units suggest that the Küseyin Formation was deposited by a meandering river and the Parçikan Formation was formed in a shallow lacustrine environment associated with swamps. The ostracod assemblages have been correlated with ostracod species of the Tethys and Paratethys regions. Cyprideis pannonica is observed in the Paratethys and Tethys bioprovinces. Cyprideis torosa, Ilyocypris gibba, Ilyocypris bradyi, Heterocypris salina, Candona angulata, Candona neglecta Sars are known in Europe and the Tethys bioprovince.
Abstract
The Neogene Alibonca, Küseyin, Parçikan, Boyaca formations and the Mamaar volcanic unit occur at Arguvan (Malatya, Eastern Anatolia). Nine species of ostracods were identified and assigned to four genera in samples collected from the Küseyin and Parçikan formations. The faunal content in these units was characterized by few ostracod species and abundant individuals. Most samples contained fewer than nine species. Ilyocypris bradyi, Ilyocypris gibba, Candona parallela pannonica and Heterocypris salina are described in the Küseyin Formation. Cyprideis pannonica, Cyprideis anatolica, Cyprideis torosa, Ilyocypris gibba, Candona angulata, Candona neglecta, Candona parallela pannonica and Heterocypris salina are described in Parçikan Formation. Cyprideis, which has ecophenotypic ornamentations (smooth, punctuated, reticulated or nodes), is the dominant genus in the Parçikan Formation. Lithological features and fossil contents of the Upper Miocene units suggest that the Küseyin Formation was deposited by a meandering river and the Parçikan Formation was formed in a shallow lacustrine environment associated with swamps. The ostracod assemblages have been correlated with ostracod species of the Tethys and Paratethys regions. Cyprideis pannonica is observed in the Paratethys and Tethys bioprovinces.
