Dinosaurs first appeared shortly before mammals did.
Dinosaurs pre-date humans therefore there were no humans prior to the Dinosaurs.
It is believed that dinosaurs came before bats.
Before dinosaurs, there were creatures that were half reptile and half mammal, but Dinosaurs were the complete first.
the mammoth did not exist first before the the dinosaurs, in fact it existed after the dinosaurs extinction.
Humans never ate dinosaurs. Dinosaurs died out 60 millions of years before humans were around.
Dinosaurs emerged some time before the first true lizards, though there were reptiles that resembled lizards long before the dinosaurs.
Dinosaurs came before birds, because dinosaurs later on evolved into birds, therefore, making birds come along LATER then the dinosaurs. However dinosaurs were far from the first creatures on earth.
Dinosaurs never had a chance to eat human beings. The dinosaurs became extinct before humans (and mammals) evolved. Birds are believed to be the most direct descendants of dinosaurs and carrion birds eating human flesh happened before history was documented so we do not know the answer.
