Beastmen really are quite the interesting species. WFRP3 really only implies a few things for their herd. Ungor, Gor, minotaur, and Bray shaman. I think some expansion should be mentioned (and probably statted up as well) of the following for GMs considering using such creatures in their games:
Centaur
Gave (mutant babys that turn into beastmen)
Turnskin (mutants of all kinds fall into this category)
Dragon Ogre (spoiler to BFP)
Hag Tree
Herdstone
* The "Gave" and Turnskins are from "The Lost and the Damned" supplement that people have been talking about on rpggeek. The Hag Tree has been around for a while, but came up again when I was reading an old White Dwarf and bore mention again.
"Tailored" Beastmen per chaos power:
Khorngor
Pestigor (nurgle)
Slaangors (including slaancentaurs)
Tzaangors
Centaur warloks
Chaos Spawn (those beastmen and mutants fallen completely to chaos and safe enough to have around the herd)
Monsters to include: chimerae, cockatraices, dragons, eagles, giatns, gorgons, griffins/hippo', hydra, jabberwock, manticore, spiders, scorpions, chaos-treemen, wyverns, chaos hounds, rats, warhounds
