Dinosoars used to be widespread around the whole Earth and on every continent millioons of years ago. Many were found in Antarctica and penguins thought "How can a creature that is cold blooded survive here?" Later it was found that Antarctica used to be warmer when they lived though it got colder until it was very cold like it is in the present day. This made Herbert borrow Jervis Tech's Time Machine and he went there. He found bones from them.
