To the person from 2022 asking how these aren’t an early game tame, well now they are surprisingly!, I mean , if you have a pteranodon on Fjordur and go to the swamp to quickly gather some auric mushrooms for them, and fly out and go to the small aberration cave that requires no hazard suit all you have to do is find a Featherlight,

and hope there’s no rock drakes near it, ( They spawn in there as well as Ravagers, Megalosaurs,Scorpions

idk about anything else dangerous, that’s all I’ve seen that attack, unless you count roll rats that attack if you steal their gems

So in Fjordur they are technically early game ig
