I literally find hundreds just chillin on trees in the redwoods. It's really helpful to make a tree platform and just wait until one lands on your tree and then shoot it with tranqs. It's much easier then trying to shoot one from the ground, and trying to find it once it's knocked out.
Make sure you DON'T mistake them for Micros. These dudes run. I've accidentally killed one thinking it was a micro. Always use a spy glass to tell which is which. Finding these cute lil fellas is hard especially with all the thylas and terror birds around. To tame them you'll need Chitin so go kill some ants or dragonflies and then boom you have a lil buddy you can love forever, well y'know until they die or you quit.
I found one when exploring the lake/river in the redwoods, it was getting dark so I decided to rest beside a cliff for safety when I heard a scream and seen a white blurry past me, luckily it was running face first into the rocks so I threw a bola and smacked it with a club until it went to sleep, now I have a really cute parachute lizard bird.
Alright, so basically I found one of these in the wild and REALLY wanted one. But with all the fun things in the Redwoods willing to take out anything that looks at them... Well you get the idea. But when I went to a dungeon and saw a Eerie one I wanted it SO bad. So I killed that one took its creature implant, revived it at one of the obelisks and tamed that glory bird up. Now I have a light up parachute!
Hello, I am the archaeopteryx lord's wife archaeopteryx lady, and I just want to inform all of you that he has killed many of innocent people because they were hurting the archaeopteryxes to knock them out. I think this is unfair for all the innocent people who just want to tame an archaeopteryx.
