If I could go back in time I would go to the cretaceous period to see the dinosaurs. I would try to see if they were warm or cold blooded. I would go at the end of the cretaceous period so that I could see what killed the dinosaurs- a volcano, asteroid, disease, or something else. I would try to see what dinosaurs really looked like: feathered, scaled, furred, plain skin, a combination of them, or something else entirely. I would also try to bring back an egg or small dinosaur but that would be very hard with the parent dinosaurs taking care of them. Of course, I could not see any dinosaurs at all, or I could walk right into a dinosaur’s mouth.
