No, but we can look at various factors of things and make an educated guess. For instance, we know by looking at the general structure of Tyrannosa There's no way to know for sure, however the other theropod dinosaurs that did survive have excellent color vision that is Birds, for the most part What is the formula for calculating solute potential? Is there planets in the Triangulum Galaxy?
