Giant Beavers at carriable by the Argentavis. I use mine to pic up Beavers and move them away from their dams all the time. Is is the quickest and fastest method of obtaining thousands of cementing paste without any bother from the beavers. UPVOTE so that others can see and use✌️
Getting a massive TLC update in March 2018. The saddle will act as a mobile smithy, Argentavis will be able to carry with Talons as well as with its beak, reduced carry weight on obsidian and a few other unannounced resources (similar to the mammoth and wood), and will also gain a Rapid HP Regen upon eating (likely from devouring corpses and not specifically food from inventory). Like so people can see!
