Ascendant shotgun and keeping your distance. I kill them in the icelands by baiting them out into the water while I stand on the ice. Or by shooting them while standing on a cliff where you can't be reached but after getting its health down it'll run away, chase and shoot while maintaining distance.

They are dropped by alpha rexes (the rarest creature in the game) and the skull can be put on a trophy wall mount!

I just beat a lvl 90 alpha rex with a 191 rex so if you can get lucky and hit it while knocking it back it becomes a walking in the park

Bringing my giga to kill one wish me luck

Alpha versions of any dino are not to be taken on with over confidence. A level 15 Alpha (anything) is worse to fight than a level 150 version of the same dino.

i came at a level 2 one of these with three spinos thinking it was gonna be easy next thing i know my armors broken and all my spinos are dead:(

Alpha Rex panning not I am 90 level

I'm in 86 level but I cannot see 1 alpharex

Just tried a alpha rex level 20 with a level wyvern 210 and he almost killed me so dont go into them with a lot confidence as me 😭
