Abstract: A large sample of hipparion fossils, collected by D. Kovachev from the late Miocene localities near the village of Kalimantsi (SW Bulgaria), is stored in the Assenovgrad palaeontological museum. In the absence of data on the exact location for most specimens, it is difficult to make a correlation between the fossils and the stratigraphy of each of the known localities. The specificity of Cremohipparion mediterraneum skull morphology and its stage-of-evolution provide information about the probable chronologic range of the localities near Kalimantsi. Based on this information, we estimate the age of the Kalimantsi localities to be correlative between the age of Hadzhidimovo-1, or end of the early Turolian, to about the age of Pikermi, or the middle Turolian. This correlation supports previous assumptions based on the entire fauna appearance.
