New Data on Dental Morphology of Hipparion tchicoicum Ivanjev, 1966 from Western Transbaikalia, Russia.

ABSTRACT

Morphological features of the teeth were studied in the three-toed horse Hipparion tchicoicum from the Pliocene of Western Transbaikalia (Russia). Several diagnostic signs of the Chicoi hipparion were described for the first time to provide criteria for distinguishing the taxon among other fossils of three-toed horses and estimating their real diversity at the final stage of their distribution in Inner Asia.
