Your own link below implies this is an open debate; that it is at least arguable that the CHLCA is a species that would be correctly classified in Pan i.e. a chimp.
Yep, indeed i read it as well, there is not enough evidence to claim that for sure, but taxonomy is difficult even for living species on earth today. I thought, let's suppose for the sake of the argument, that Pan are different species.
I strongly recommend "You're Basically The Hagfish of Reptiles..." [1]. It will make your head spin.
