Pre-Adamite creatures and dinosaurs

We have narrations about creatures lived on this earth before the creation of Adam (AS). Many of our Ulama thought that the response of the Angles when Allah (SWT) informed them : I am creating a Human being on the earth, when they said: Do you want to create on the earth a creature who will do wrong and shed blood? It seems that the angles have witnesses creatures on the earth who used to do wrong and shed blood. Wassalam.
