Greg Paul did a drawing once of an alternate history with no K/Pg catastrophe,
in which armless tyrannosaurs hunted neo-hadrosaurs
in the Cenozoic grasslands, with herds of horned non-ceratopsid ceratopsians in
the background. If memory serves, the drawing was in
a book review of Dougal Dixon's Alternate Dinosaurs book in Evolutionary Theory.
Don't know if that picture is on the web anywhere.
