RE: Ancient raptors likely feasted on early humans

Tommy, maybe you forgot the New Guinea Harpy Eagle, Harpyopsis novaeguineae

(see e.g. http://www.baldeagleinfo.com/eagle/eagle6.html for an overview; I
don't know if 'Buteonine or Harpy eagles' are considered a clade, and I'm
surprised they ever were assumed to form a natural group, considering their
fragmented distribution)

There used to be one of these in an aviary at Taronga Zoo, Sydney, in the
mid-70's when I used to spend a lot of time there (I'd walk a few miles to
get there nearly every weekend in 1976, often Saturday and Sunday), and I
always stopped in to spend a few minutes or more with this spectacular and
vocal but rather lonely bird.

Of course New Guinea has no monkeys, but plenty of arboreal possums and tree
kangaroos which are more or less ecological equivalents (and probably taste
similar).  If Harpyopsis is really part of the same radiation as 'Harpies'
in the Philippines and Africa, there must have been similar species right
across southern Asia not too long ago.  They seem to need really big patches
of forest; it'd be worth looking for those fossils in Borneo and Sumatra.
