I'm publishing the English-language description of _Dinotyrannus_ in
_Mesozoic Meanderings_ #2 third printing, now that Gakken's dino mag has
folded. Molnar (1980) distinguished the holotype from _Tyrannosaurus_, and
suggested it was a large adult _Nanotyrannus lancensis_ (then called
_Albertosaurus lancensis_).
