Doctor explains dinosaur extinction cause
Plot Beats
The narrative micro-steps within this event
The Doctor discusses the extinction of dinosaurs with Tegan and Nyssa, explaining the impact of an asteroid on Earth's ecosystem.
Tegan questions the possibility of one asteroid causing the extinction of all dinosaurs, leading to a scientific explanation from the Doctor.
Nyssa and the Doctor further elaborate on the effects of the asteroid impact, including the prolonged storm and temperature drop.
Who Was There
Characters present in this moment
Controlled intensity masking urgency beneath the lesson
Crouched with chalk-like precision, the Doctor draws a broad outline of a bulky hadrosaur while framing the asteroid’s apocalyptic aftermath with sweeping, didactic authority. His voice slides between pedagogical calm and mounting gravity as he visualises dust clouds blotting the sun.
- • Educate the companions about mass extinction events
- • Prepare them to grasp ecological fragility
- • Knowledge of cosmic threats can guide protective action
- • Future catastrophes can be anticipated and mitigated
Initially incredulous, reluctantly moved by the imagined fate of the dinosaurs
Standing with arms crossed, Tegan listens with sceptical intensity, pressing the Doctor on the plausibility of a single cosmic event exterminating every dinosaur. Her questions pivot from doubt to quiet empathy by the end.
- • Challenge the Doctor’s explanation to test its validity
- • Stay alert to the underlying sounds of danger nearby
- • Claimed disasters require overwhelming evidence to be believed
- • Empathy for vanished species underscores the lesson
Composed yet quietly attentive to the escalating environmental stakes
Adjacent to the sketch, Nyssa reinforces the Doctor’s points with precise scientific detail, adding the notion of displacement and prolonged climatic disaster. Her measured tones frame months of darkness and plunging temperatures as inevitable outcomes.
- • Clarify the chain of ecological consequences triggered by the impact
- • Collaborate with the Doctor to deepen the lesson
- • Environmental systems exhibit cascading vulnerabilities
- • Precise data anchors understanding of catastrophic events
Objects Involved
Significant items in this scene
Initially absent, Nyssa’s rough pencil sketch of a vegetarian dinosaur was fashioned quickly in loose soil outside the TARDIS, becoming the visual anchor for the extinction lecture. It remains crudely detailed—bulky frame, downturned muzzle, grinding teeth—while the Doctor and Nyssa annotate it verbally to map Earth’s doom.

Doctor warns against E-space planKey Dialogue
"DOCTOR: It's size. It was gigantic."
"TEGAN: But how could one asteroid wipe out all the dinosaurs? It just isn't possible."
"DOCTOR: The impact would have caused millions upon millions of tons of earth and rock to be fragmented and then hurled up into the atmosphere, enveloping the whole planet."
