Ornitischian revenge! Edmontosaurus regalis uses its sheer mass to knock and hold down an Albertosaurus while the nasty beak punishes the reckless theropod.
Because hadrosaurs are more than mere cannon fodder and, at the end of the day, size matters.
As much as I love coelurosaurs, I do love these types of works in which hadrosaurs are shown defending themselves as that would be more realistic than them going down without a fight.
Thanks! yeah, it makes no sense that such heavily constructed animals are taken down without even putting a fight. All adult hadrosaurs were stronger and heavier in general than any contemporary tyrannosaurid; they certainly weren't dinosaurian sheeps.
What really grinds my gears are dromaeosaurs taking down hadrosaurs hundreds of times their own size in only packs of few. In fact, I came up with a conclusion that the only reason some people think T. rex is a scavenger is because of this raptor cliche.
That's even worse. There's not enough pictures of 20-70 Kg dromaeosaurs receiving a deadly reality check from some multiton ornithopod. Heck, even something twice its weight could kick the butt of any dromaeosaur. Not to mention how dubious is this pack hunting theory alone...
It's funny how this argument is brought out so often, since juvenile and sub adult speedy tyrannosaurs were probably a much tougher competition for any adult Rex than any deinonychosaur, pack hunter or not. We even have healed bite marks that prove how they went after living prey (and most important of all, usually failed).
