Dental and horn core/antler morphology is discussed for some representative lower and middle Miocene pecorans in a review of the phylogeny and early zoogeography of the modern Old World families. Giraffes and bovids are more closely related than either is to deer. Andegameryx, Walangania and Teruelia are related to giraffoids plus bovoids together; Amphimoschus and Hispanomeryx are a probable sister group of bovoids; Propalaeoryx is the sister group of the giraffids plus climacoceratids. Procervulus and Lagomeryx may be closer to modern deer than are Stephanocemas and Dicrocerus but all are included in the Cervidae. The horn structure of Palaeomeryx has resemblances to giraffids, but its teeth and postcranial bones are more like cervids and it is placed in the Cervoidea. Pecorans seem to have evolved in Eurasia and there gave rise to deer. By the early Miocene some pecorans had entered Arabo-Africa where they gave rise to giraffids and probably bovids. The relationships and zoogeography of the early bovids Eotragus, Homoiodorcas and Caprotragoides are likely to be important for later bovid history. |
