Observations on the postcranial anatomy of Hoplitomeryx (Mammalia, Ruminantia, Hoplitomerycidae) from the Miocene of the Apulia Platform (Italy)

摘要

The untypical ruminants of the Apulia Platform (central and southeastern Italy), originally accommodated in the genus Hoplitomeryx, have been recently revised. The Scontrone (Abruzzo, central Italy) representatives were included in a new genus, Scontromeryx, with the addition of a new species, Scontromeryx mazzai. In contrast, the Gargano ones were left in Hoplitomeryx, but also in this case with the addition of three new species, Hoplitomeryx devosi, H. macpheei, and H kriegsmani, described on postcranial remains and based on body mass calculations and using a size class scoring technique. The results of the present study show that Scontromeryx is invalid, that S. mazzai is imperfectly defined, and that H. devosi, H. macpheei, and H kriegsmani from Gargano are based on dubious body mass calculations and size class scoring.
