The funny thing about this bird was scientists used it as an argument against the monophyly of the palaeognaths - basically ostriches were giant, flightless cranes.

So was this a wetland bird or a grassland bird?

With didactylous feet - grassland!

Ah, because didactylous feet would have little area to spread out the weight to prevent sinking into soft mud. But prefect for directing thrust efficiently with reducing drag.
