The Third Doctor and Sarah Jane Smith acknowledged the Tyrannosaurus rex as one of the species which died out.

History of the impact[[edit] | [edit source]]
Anticipation[[edit] | [edit source]]
By accounts in which the late Cretaceous coincided with the Age of the Silurians, this impact was anticipated by some of the Earth Reptiles.
The Sea Devils who lived on Earth during this time survived the extinction event by plunging their aquatic colonies into a state of hibernation. (COMIC: Clara Oswald and the School of Death [+]Loading...["Clara Oswald and the School of Death (comic story)"]) Other accounts presented the Silurians going into hibernation in anticipation of the coming of the Moon, (COMIC: Clara Oswald and the School of Death [+]Loading...["Clara Oswald and the School of Death (comic story)"]) and in other eras preceeding the evolution of homo sapiens. Historians observed that different tribes of Silurians entered cryogenic suspension at different times to avoid numerous disasters over the millennia, (PROSE: The Monster Vault [+]Loading...["The Monster Vault (novel)"]) with account suggesting that the Silurians and some dinosaurs survived the impact event.

Impact[[edit] | [edit source]]
When the Neomorph Cybermen (AUDIO: The Ultimate Cybermen [+]Loading...["The Ultimate Cybermen (audio story)"], etc.) attempted to bombard Earth with Briggs's freighter in 2526, Adric tried to change the freighter's course but the control system was damaged by a Cyberman. Adric had no choice but to redirect the freighter through time to crash it into prehistoric Earth rather than 26th century Earth. (TV: Earthshock [+]Loading...["Earthshock (TV story)"]) By one account, Adric was rescued at the last minute by the Tremas Master, who later tried to use the captive Adric as leverage in a revenge scheme against the Doctor. (PROSE: The Cyber Files [+]Loading...["The Cyber Files (novel)"])
By most accounts, the impact occurred in the region that would become Mexico, creating the Chicxulub Crater. (PROSE: The Dragons of Prague [+]Loading...["The Dragons of Prague (short story)"], Cat's Cradle: Time's Crucible [+]Loading...["Cat's Cradle: Time's Crucible (novel)"], The Gulf [+]Loading...["The Gulf (novel)"]) However, one account showed the freighter as having crashed into West Africa.

After his death, Adric's consciousness was put in the Nethersphere by Missy. (PROSE: Seb [+]Loading...["Seb (short story)"], The Secret Diary of the Master [+]Loading...["The Secret Diary of the Master (short story)"])
At one point while discussing the impact event which killed the dinosaurs, Iris Wildthyme acted shiftily while remembering the time she had visited the Yucatán Peninsula, suggesting she had some involvement with the event.

The Cloud[[edit] | [edit source]]
- Main article: The Cloud
The impact displaced earth and rock into the sky, creating a storm known as the Cloud that enveloped the planet (TV: Earthshock [+]Loading...["Earthshock (TV story)"], AUDIO: The Adolescence of Time [+]Loading...["The Adolescence of Time (audio story)"]) and lasted for months (TV: Earthshock [+]Loading...["Earthshock (TV story)"]) or years. (AUDIO: The Adolescence of Time [+]Loading...["The Adolescence of Time (audio story)"]) It blocked out light and heat, causing the reptiles to die from the temperature drop. (TV: Earthshock [+]Loading...["Earthshock (TV story)"])
The impact also "cracked open" the planet and released "forces, powers, things that had been trapped in the Earth since the beginning". As a result, the Earth Reptiles gained psychic powers, wild fields formed in the skies which allowed for floating islands, and the Wyrm was released from the centre of the Earth. While the Silurians and Sea Devils remained on the surface, the Chicxulub fled to the skies to avoid the Cloud which choked the planet. (AUDIO: The Adolescence of Time [+]Loading...["The Adolescence of Time (audio story)"])
Madame Vastra believed that the Myrka had gone extinct during this time, but they had in fact survived and would be utilised by surviving Silurian tribes. (COMIC: The Lost Dimension [+]Loading...["The Lost Dimension (comic story)"]) She also recalled having last seen the Crimson Horror, which had plagued the Silurians during this time. After finding one in 1893, the Eleventh Doctor suggested returning it to the Jurassic era. (TV: The Crimson Horror [+]Loading...["The Crimson Horror (TV story)"])
At some point in his life, Jack Harkness had to survive on dinosaurs, which he recalled were the "only source of pre-killed food protein after the asteroid crashed". (TV: Fragments [+]Loading...["Fragments (TV story)"])
Aftermath[[edit] | [edit source]]
One history book indicated that some dinosaurs survived the extinction event, eventually evolving into the Silurians and Sea Devils by the Age of the Silurians in the Eocene era. (PROSE: A History of the Universe [+]Loading...["A History of the Universe (short story)"])
Other realities[[edit] | [edit source]]
In the 19th century, the Fifth Doctor attempted to use Block Transfer Computation to redirect his TARDIS to him. He subconsciously appeared to Adric on the freighter as a ghost just before he died and fed him numbers for entry into the computer, creating a bubble universe in which Adric survived the freighter's descent to Earth.
Adric tamed the giant scorpions on prehistoric Earth and built and ruled a City of Excellence using Block Transfer. In this timeline, the giant scorpions flourished and caused the extinction of reptiles through overhunting. He extended his own life and lived for five hundred years, hoping to get revenge on the Doctor for not saving him as well as to take Nyssa as his wife. When the Doctor and Nyssa finally arrived, the scorpions turned against Adric to prevent him from leaving, and thus destroying, the bubble universe. Adric learnt his lesson and, after helping Thomas Brewster pilot the TARDIS back to the Doctor and Nyssa, finally died.

Legacy[[edit] | [edit source]]
Señor 105 believed that whatever had caused the Chicxulub Crater brought alien influences with it, which periodically reawakened and caused supernatural events around Mexico, New Orleans, and the Bermuda Triangle. (PROSE: Iris Wildthyme y Señor Cientocinco contra Los Monstruos del Fiesta [+]Loading...["Iris Wildthyme y Señor Cientocinco contra Los Monstruos del Fiesta (short story)"])
The Fifth Doctor told Tegan Jovanka that her ancestors were at a "very primitive" evolutionary stage when the dinosaurs died out. (TV: Earthshock [+]Loading...["Earthshock (TV story)"]) With the dinosaurs extinct, the creatures that would eventually become homo sapiens continued to develop and evolve. (PROSE: The Whoniverse [+]Loading...["The Whoniverse (novel)"])
By an account by which Adric was saved by the Master, the Celestial Intervention Agency interviewed him as a firsthand witness of the extinction event. (GAME: City of Gold [+]Loading...["City of Gold (game)"])
The Twelfth Doctor once corrected a history book at Coal Hill School which had a couple of pages "giving all sorts of daft theories" including "stuff about meteors and asteroids and comets" which were "all complete rubbish". He replaced this with the story of Adric's death. (PROSE: A History of Humankind [+]Loading...["A History of Humankind (novel)"])
In 2367, the Eleventh Doctor noted that the dinosaurs aboard the Silurian Ark, then in the possession of Solomon, would be very valuable given their supposed extinction. These dinosaurs were saved by the Doctor, who housed them on the planet Siluria. (TV: Dinosaurs on a Spaceship [+]Loading...["Dinosaurs on a Spaceship (TV story)"])
Other accounts of the extinction[[edit] | [edit source]]
The Second Doctor believed that the dinosaurs had been made extinct by the First Ice Age, with this seemingly being confirmed by his encounter with Jurassic apemen who were also made extinct by the Ice Age. Before encountering the apemen, Jamie McCrimmon believed that the dinosaurs had been made extinct by constantly fighting each other to death. (PROSE: The Dragons of Kekokro [+]Loading...["The Dragons of Kekokro (short story)"])
An omniscient life force once relayed the truth that the dinosaurs had been killed by the greatest Dalek War Fleet ever assembled. A Dalek Vault was built under the future site of London at this time. (COMIC: Invasion! The Enemy Within! [+]Loading...["Invasion! The Enemy Within! (comic story)"])
