Tyrannosaurus Drip by Julia Donaldson and David Roberts

The duckbill dinosaurs are peace-leaving herbivores while the blood-thirsty T-Rex and his gruesome bride are the complete antithesis. So what happens when the egg of a Duckbill dinosaur accidently makes its way into the nest of a grizzly T-Rex? The T-Rex siblings cruelly name the hatchling ‘Tyrannosaurus Drip’ because he refuses to take part in their blood-thirsty antics. But they have underestimated this plucky little herbivore who uses his large brain to overpower the cowardly T-Rex family.
