The other ferugliotheriid genus, Fusuamys (a pun on Chibcha fusuamuy, "maize", and Greek mys, "mouse") is represented by two hyrax-sized species, F. gameri and F. kosemeni, distinguished by aspects of the ankle articulations and more lophodont teeth in the former's case. Larger than Funzaiomys, Fusuamys was more cursorial (being the only local herbivore to be specialised for running) and had more lophodont dentition, suggestion a speciation towards browsing. It likely occupied a mid-sized herbivore niche alongside the smaller Glyptoguy species, with F. gameri in particular showing adaptations for climbing; overall, a comparison to our hyraxes or goats is not to far off, if less capable of eating grass. Fusuamys shows several similarities to Australian ferugliotheriids, suggesting that it might have been yet another kigration from the south; however, it is less similar to Patagonian and Antarctic taxa that existed in between, offering a puzzling mystery. Are members of this clade yet to be discovered in southern South America and Penguinland? Or does it represent an older ferugliotheriid lineage largely displaced to the fringes of their former range? Another possibility is that these similarities are just convergent evolution. Who knows.
