Re: Gastornis bone isotopes indicate herbivorous diet



Even if largely herbivorous, I'm sure it wouldn't have hesitated to use that 
beak on any potential 
nest robber, or anything attempting to make a meal of the bird itself.

Plenty of modern herbivores are also not averse to eating the occasional bit of 
meat (deer killing 
and eating birds, cows snacking on rabbits, hippos scavenging from carcasses, 
etc). Mineral 
deficiencies in particular can cause herbivores to seek out animal prey - and a 
large bird that layed 
large thick-shelled eggs might just have had a craving for bones (alive or 
dead) at certain times of 
year to gain that extra bit of calcium.
