A New Transitional Anthropoid from North Africa?

Readers might recall from our discussion of afrotarsiids that some paleontologists now incorporate this group within the radiation of mostly Asian stem anthropoids known as eosimiiforms. Well, in July, several members of the same team that discovered the early afrotarsiid fossils described a new putative early anthropoid from the middle Eocene (~40 Ma) of Tunisia (Marivaux et al. 2014). They further suggest that this fossil may represent a transitional form linking eosimiiforms and the simiiform radiation of crown and advanced stem anthropoids.

This group of three known species was first assigned to the tarsiidae, but is now often argued to represent a group of early stem anthropoids. For my overview of the certain members of the Tarsiidae, see Part I.
