New evidence of conspecificity between Hipparion primigenium melendezi Alberdi, 1974 from Los Valles de Fuentidueña (Segovia) and Hipparion concudense concudense Pirlot, 1956 from Concud (Teruel, Spain)

Abstract

This paper reports a morphological and biometric comparison of Hipparion primigenium melendezi from Los Valles de Fuentidueña (Segovia) and Hipparion concudense concudense from Concud (Teruel) to investigate their possible conspecificity. Comparisons with other Spanish (La Roma 2, Puente Minero, Milagros, Las Casiones and Venta del Moro) and Eurasian (Höwenegg, Germany; Pavlodar, Kazakhstan [small form]) material were also made. Based on their morphology, and on bivariate and multivariate analysis to establish size similarities, the Hipparion remains from Los Valles de Fuentidueña and Concud were both determined to belong to Hipparion concudense. However, differences in both dental morphology and limb slenderness could suggest differences at the subspecific level.
