Check out the deleted scene that was recently released from Marvel’s Eternals, and it gives some insight into the history of Earth, the Eternals, and the Deviants. In fact, it’s revealed in the scene that Dinosaurs were actually Deviants, and it’s implied they were wiped out by the Eternals.
The scene features Lia McHugh‘s Sprite and Kit Harrington’s Dane Whitman walking around London’s Natural History Museum while Dane’s girlfriend Sersi (Gemma Chan) is giving a presentation on apex predators. It’s during this scene that Sprite starts dropping bombs on Dane and telling him, but he is confused by the mind-boggling information that she’s sharing.
