I have one rex and im trying to find out what level you get the saddle im only lever 28 so that really helps

For fiber best is sickle

For hide and animal or an axe

And for metal ankylosaurus or an pick

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

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.

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

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

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

Haha

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