I freely admit, I googlized this, as my knowledge of dinosaurs is very limited, but the Stegosaurus would be my choice as it’s recognized as the friendlist, and it’s herbivorous. I guess the last thing the world needs is the return of a dinosaur, but if it happened I’d want the most compassionate one I could find.

Down in the valley together
Down in the valley with love by our side
Down in the valley together
My imposition crucified
