Why is the discovery of new dinosaurs important?

because discovering them, or finding traces,fossils, or any biological remains about the dinasour makes the scientist unlock the mystery of past era, and also to know how they live at past (were humans doesnt have great intelectual capacity).and it lets the humans of this era understand it better than what they would have by some one just telling them in person it also help scientist put 2 and 2togetner and so one day they can come up ona true theory on how dinosaurs died and what caused it
