Take a trike (lvl. 20+), and a stego (lvl. 20+) while on a parasaur (lvl. 30+) and you got this. Trike died, but took most of the initial damage. Stego delivered great damage and survived, parasaur is more of a distraction. Or you can shoot from your mount (highly recommended) Also received a T-REX hat skin so I can wear the skull on any helmet or hat. Looks pretty dope. Hope this helps!!

I just encountered one I killed it with my sabertooth and that was a close call my sabertooth almost died. But still we survived

Get a spino level 5 or higher with stats straight into attack

Best way to get this item is killing a Alpha Raptor. I-It's that easy....

Just shoot 15 arrows with a crossbow when he is busy with an Argentavis dead body, then go fight like a sigma boy with a sword and a shield (and at least 300 HP). So easy right ?!
