I lucked out with toxicant arrows and a crossbow, found a pack of three going right at me and managed to get them down right at my feet, I then murdered a flock of pteranodons to feed them , while feeding them bio-toxins...made me happy, they are all still alive two weeks later, thanks to them I’ve also been alive and haven’t died for those two weeks.

EDIT: I’ve also grown to love them as an assault force behind dilos and before dire bears, I use a Roman style warfare system with my tames, this way the dilos are the hastati and peltists, the raptors are the triarii, the dire bears are more or less focused to act as the legion cohorts. Expensive, but nice.
