Those in dinosaur research might well be aware of a joke SVP abstract a few years back that claimed Stegosaurus was a cursorial biped. That however has nothing on this report from 1920 that describes this substantial animal was a glider, using its plates for wing. As far as I can tell it’s quite genuine. It’s also awesome. Go read.
My hat is tipped in the direction of John Hutchinson and Jeff Martz for this.
