And given that the skeleton of _Moeritherium_ is far more like the legged
sea-cows than most reconstructions suggest, you can make
the argument that Proboscidea is "neoterrestrial" (from an amphibious rather
than aquatic ancestor).
Of course, none of this actually represents evidence of secondarily flightless
