Dr. Oliver has three dinosaur species names on the board: Stegosaurus, Brachiosaurus, and Brontosaurus, as dinosaurs from a prehistoric era. Brontosaurus in reality never existed, it was conceived when a museum mixed up two different dinosaur skeleton's and they believed they discovered a new species. As an expert on Dinosaurs Tommy should have known this.
When Dr. Oliver goes to morph, he doesn't insert the key into the morpher. Instead, the key runs across the top of his morpher so he technically shouldn't have been able to morph.
