Holocene New Zealand (Haast's eagle, Eyles' Harrier, NZ Longfin Eel. The first two extinct due to people)
I want to have most predators as female, because a. female predators are more BA (bigger, faster, smarter) than males and b. I am sick of portraying predators as masculine when the reality is the opposite.
