Do missions if you’re not the exact level or you can get loot drops you have a 1% of getting it or it just random. Hope it helps

I tamed one before I got a saddle and I waited so long to ride it

A good way I found to get chitin is farming the scorpions with a axe you get like 120 -140 each

Works as a smithy but you can’t repair things in it

Kill trillobits and you will get a lot of chitin

Kill bugs to get the most chitin

a good way to get metal is to breed a pack of argentavis and make them follow you when you go to farm metal because they have a metal weight reduction so you can carry more and don't forget to get a ankylosaurus for more metal

don’t bring your bird in to a sticky situation

Tame a saber and cave or look for bugs they get around 40 chitin per kill

If you need chitin but u can t find trilobites just head to a cave and kill some araneos and scorpion
