However, the fact that many ornithodirans, from pterosaurs to ornithischians
to modern birds have/had horny beaks may indicate that the presence of a
horny covering over part of the jaws (the premaxilla?) might have been a
primitive character for the Ornithodira
(dinosaurs+pterosaurs+"lagosuchians"). This is purely speculation, of
course, but some sort of beak on _Tyrannosaurus_ is not *completely*
BTW, _Tyrannosaurus_ was a five-ton *dinobird*.
