Nasal architecture in <i>Procynocephalus wimani</i> (Early Pleistocene, China) and implications for its phyletic relationship with <i>Paradolichopithecus</i>

Procynocephalus and Paradolichopithecus are large Eurasian papionins from the Middle Pliocene to Early Pleistocene. The two genera are regarded as being phylogenetically close, but their phyletic position is still disputed, in particular regarding to which subtribe, Papionina or Macacina, they are close to. Many fragile structures of the nasal region are well preserved in the type specimen of Procynocephalus wimani from the Xin’an locality in...
