If this is true it's news to me: most sources state how strong the
cassowary crest is. It's also interesting that the crest serves as a
tool: the Perrins and Middleton bird encyclopedia includes an
observation of a cassowary using its crest to overturn soil when
searching for food!
It would not be realistic to apply _this_ function to crested
non-avian dinosaurs, seeing as they generally have forelimbs for the
job (especially crested theropods). Recalls somewhat the
recent suggestion that _Parasaurolophus_ dug stuff up with its crest
