The pig Propotamochoeurs palaeochoerus from the upper Miocene of Grytsiv, Ukraine

Abstract

The suid form Grytsiv (= Gritsev) in Ukraine belogs to the genus Propotamochoerus. This genus was not yet known from the Miocene of eastern Europe. The Grytsiv suid is described and its significance is discussed within the paleobiogeographical and stratigraphical framework of the genus Propotamochoerus. Grytsiv is geographically situated between three areas with different species of the genus: W. Europe (P. paleochoerus), China (P. hyotherioides) and the Indian Subcontinent (P. hysudricus). In Europe, P. palaeochoerus is replaced at the MN 9-10 boundary or early in MN 10 by a different species of Propotamochoerus with affinities with P. hyotherioides or P. hysudricus. The fossils from Grytsiv extend the known range of P. palaeochoerus eastward into Ukraine.

El suido de Grytsiv (= Gritsev) en Ucrania pertenece al género Propotamochoerus. Este género todavía no se conocía en el Mioceno de Europa oriental. Se describe el suido de Grytsiv y se discute su significado dentro del marco paleobiogeográfico y estratigráfico del género Propotamochoerus. Grytsiv está situado entre tres áreas con diferentes especies del género: Europa occidental (P. palaeochoerus), China (P. hyotherioides), y el Subcontinente Indio (P. hysudricus). En Europa, P. palaeochoerus fue substituido en la transición MN9-10 o a MN10 por una especie distinta de Propotamochoerus con afinidades con P. hyotherioides o P. hysudricus. Los fósiles de Grytsiv extienden su distribución geográfica conocida de P. palaeochoerus por el este hasta Ucrania.

The suid remains from Alhambra are described and assigned to Conohyus simorrensis. Conohyus is well known in Spain from late MN5, or zone E, MN7+8, or zone G and MN9. The material from Alhambra folls the gap in the Iberian record. The Iberian record shows that Cononhyus evolution occurred in a larger area that extends from Western Europe to Anatolia. We present an overview of the European and Anatolian localities with Conohyus.
