First Pluto. Now T Rex?
Did all dinosaurs have “feathers”? | Our feathered friends | The Economist
... Taxonomically, the very definition of a bird was until recently an animal that has feathers. Now, taxonomists argue that since birds are descended from dinosaurs they should be classified merely as a subgroup of the Dinosauria. But if feathers truly are the diagnostic criterion, then perhaps things should be the other way round, and Stegosaurus, Triceratops, Diplodocus, Tyrannosaurus and their kin should no longer be thought of as terrible lizards, but as overweight, flightless birds.
It must stop now.
While triceratops was from the Cretaceous one does appear in the movie Jurassic Park.
