If we're getting this silly...
It is now apparent that, like the defenses of the South American ground
sloths, ankylosaurs had some manner of bony armor under their dense layers of
feathers. (Oh, yeah, and the keratinous tail club was a predator-distraction
device covered with feathers that served as a display structure, a heat-
dissipation device, and were used in brooding, all of these features of
being derived from that of the ancestral arboreal ankylosaur which leaped
gracefully from tree to...well, the ground).
