Monodactyl Equids from Konso, Discussion
mardi 3 octobre 2017
Discussion
Gen Suwa et al., 2003 distinguish an earlier fauna, with endemic bovids, prior to 1.7 Ma, followed by “an influx of external elements…most likely related to a general East African trend of climatic drying†, resulting in “the post-1.5 Ma characterized by newly occurring taxa (…)

The material from Konso comprises one beautiful cranium and many limb bones most of which are unfortunately fragmentary. The whole is not homogeneous.
Most limb bones suggest the existence all through the sequence of a robust Equus. Only those from Interval 5, KGA 12 have (…)
