Brides have been known to use tools and there are a few species of prey dropping birds out there that drop their prey on the ground to crack it open.
Now I’m not suggesting that there was a bird capable of picking up a rhino but possible capable of picking up individual bones and dropping them or like crows picking up rocks and dropping them on the carcass.
The former is actually a thing:
The bearded vulture has learned to crack bones too large to be swallowed by carrying them in flight to a height of 50–150 m (160–490 ft) above the ground and then dropping them onto rocks below, which smashes them into smaller pieces and exposes the nutritious marrow.
- dogma1138 9y agoBirds ffs iPhone, brides using tools isn't that impressive i think.
- pavel_lishin 9y agoSure, but the article makes it sound like these are very specifically hand-tools - but I didn't read any of the actual research. And as I recall, the Pacific is one of the places where some pretty damn big birds live, probably big enough to crack open big mammal bones with just their beaks.
