Megatherium is easy tame and theri isn't bcz theri also take so long! So tame a Megatherium for fiber!

Tame a Moshops if at start of the game and just harvest some bushes. If not, then get a lot of Gigantopithecuses and put them on wondering. Then just wait.

Use the therinzs tickle attack will running. I get ove 1k in a few seconds

When going to a swamp, bring a therizino to get an easy 100k fiber in minutes, I did this for about 15-20mins and I made over 859k and a good amount of rare flowers and rare mushrooms

Therizino is the best at gathering fiber.Mine gathers like 1000 from 7 bushes

Use a asc sickle with a mantis with half levels into movement then half into anything u want

Press C or Right Stick on the Gigantopithecus and you’ll easily get a ton of fiber per bush

On aberation you need big quantitys of fiber for ziplines so I suggest you use a dire bear for getting shrooms for recipes and spore immunity, and fiber of course. IMPORTANT to maximize your fun and travel use the zip lines while your riding a ravager/giagantopithicus

Use a therein, they get less per bush than a sickle but do the delicate attack while running and you will get over 1k in a few seconds

Oh fiber I'm always running out of it Moschino please just come back I need that fiber

Zinos may be rated 3rd on here but they are the best for gathering fiber, max out points to delicate harvesting for better results

Set a moschops in a closed area with lots of plants, you're welcome

I think the best fiber harvester is the Moschops. I had one who could get 150 out of one bite with standard settings.

Use a sickle to harvest bushes it gives u lots fiber in about 30 seconds

On mobile, I take a dire bear, double tap and hold to do repeated attacks, and just run through the jungle. Just make sure to dump the berries as they fill up your weight easily, and beware of raptors.

If you are just starting of the first thing you should do is tame a moschops.

if you do not have a tamed dinosaur that is good at collecting fiber , you can easily craft a sickle tool, and they are great for collecting fiber if you dont have a dino for it!

Moschops can gather fiber, but if they are far away from your tames (even if its on neutral), anything attacking it, even compys will kill it. Moschops NEVER fight back, they just run. I have one and some foolish dilos attacked my dinos, so we easily slaughtered them. Unlike the others, the moschops just ran away. Neutral aggression? More like coward aggression.
