Since nobody talked about it

The underwater caves on the "TheIsland" map are THE best way to obtain quality rex saddles, if you don't have that option I have a few recommendations:

Valguero: There a easy cave with no dinos where you can get 2 Yellow Loot Drops, 2 Blue Loot Drops and 2 Red Loot Drops, just make sure you have a flyer, a perfect one would be the Pteranodon

Ragnarok: Do runs in the ice cave, but make sure to grab the Loot Drops in the area before you grt into the actual caves, just lure the bears down the cliff if they agro on you

Abb: Well, basically just the Loot Drops sadly.

Extinction: Yellow, Red or Purple OSD, I recommend the Red one though

Gen/Gen2: Honestly, Pay2Win, just do the missions

Scorched Earth: Desert drops

Crystal Isles: Land drops located in the snow biome

Hope that this helped a few people, and it will take some time to get the saddles, just do not give up, it'll be worth it.

Rex saddle is L.V 74. And it's pretty easy to make.

taming rexex is easy but the only problem here are saddles. from few other comments I can tell that you can get rex saddle blueprint from ice cave and underwater caves.

(hope that helps)

For fiber best is sickle

For hide and animal or an axe

And for metal ankylosaurus or an pick

I got 5x Rex now and im only lvl 58.and my only tips for bigginers dont tame rex when your lvl is only 10+ or 20+ cause its gonna be hard to grind you to unlock the saddle my only tip is grind first before you tame it.i wish it helps.up it.so i can help other begginer s😀😀😀

I think something good to get fiber is a therazinosaurus with his wiggly fingers

Tame a Rex closer to level 74 because it is easy to get a satle

It will be easy for me to get the metal cuz I’m only lvl 53 and I have 7597 ingots I will give you a tip go to east zone 1 you will see a small herbivore island and tame a sarco and get to that island I recommend to get a good weight sarco and then just farm and you will get a lot of ingots just from that island I got 2000 METAL ingots

Swamp cave in the redwoods on the Island map seems to have a high chance of having really good rex saddles/BP in the red drops in there

On multiple different servers I always seemed to get a BP

If you want hide for this killa just a carno and just farm alot

Haha

Hide is easy I have thousands of it allosaurs are great to just go and kill brontos for their hide.

I hunt rex for games. And claim arma and bunch of stuff i mean i'll have everything for this dino im just not ready to tame one them yet. But they make a game fun to hunt im already lvl 78. Find 8 of them and shoy them all

I have 3 Rexes now, and i’m only level 68. I guess i’m just a fast developer!

How to get killed by Rex

1:insult it

2:and you die

Or just punks it and become a Rex food

Rex my ferite dinosoure

Thanks

If you have a tapajara latch onto Mountain or the crossbow Trank then feed prime meat I have a level 23

Normal map east near the winter biome

Please note that if you see a really big "rex" and you scope in on it and it says "giganoto" or something like that, if you can tame it. Then put a rex saddle on it (doesn't work)

Your dead BTW

My ark survival evolved into rex saddle

Bro most of the comments are not helpful look on gen 2 or loot loot crates for good sadle bps then you have a Rex for the boss fights.

For some reason I have to travel over 3k meters from my base to find a rex the only rex spawn point that ik is near the snow biome that's the only spot I can find ankys or rexes
