Silurian The Silurians , also known as Earth Reptile s , Eocenes , Psionosauropodomorpha , Homo Reptilicus , Homo reptilia and Reptilia sapiens , were a species native to Earth that pre - dated human ity . Technologically advanced , they lived alongside their aquatic cousins , the Sea Devil s . Unlike other species , Silurians showed an important intraspecific variation , with vast differentiation between breeds , such as the number of eye s , the formation of their pupils and the colour of their skin . Biology . Physical appearance . The Silurians were an extremely varied species , with different subspecies and appearances ; there were at least ten or eleven Silurian variations . Whilst many of them appeared similar , there were subtle differences which were attributed to caste . There were also clans or families with differentiated physical characteristics , some suited for environments of extreme cold or high plateaus . ( PROSE : " The Scales of Injustice " ) In general , they were humanoid reptilians with scaly crests on their head . There were also distantly related to the Sea Devil s . ( TV : " The Sea Devils " ) They were genetically divergent enough to create problems for the offspring of matings with Silurians . Offspring suffered from biological problems including sterility and a shorter lifespan , due to cellular degeneration . ( PROSE : " The Scales of Injustice " ) Some Silurians become darker green when blushing . ( TV : " The Name of the Doctor " ) In at least one alternate reality , there was a human - Silurian hybrid . This demonstrated that mating between the two was possible . ( PROSE : " Spiral Scratch " ) Anatomy . Silurians were cold blooded and could only survive at warmer temperatures . They were sluggish and slow when cold . ( PROSE : " Blood Heat " , TV : " The Hungry Earth " ) Silurians had a hunter ' s anatomy , with powerful muscles and hollow bones . Though they were taller than human s , they were also lighter and faster . According to one account , Silurians were incapable of crying , ( PROSE : " Blood Heat " ) although another account showed Silurians did indeed cry . ( PROSE : " Doctor Who and the Cave - Monsters " ) The typical lifespan of a Silurian was 200 to 250 years , ( PROSE : " The Scales of Injustice " ) though some lived up to 300 years . ( TV : " Cold Blood " ) Silurians had an organ analogous to the human pituitary gland . ( PROSE : " Burning Heart " ) They had a greater lung capacity than a human . ( TV : " Deep Breath " ) Nanjura fruit s were toxic for them , but not lethal . ( COMIC : " Supremacy of the Cybermen " ) The reptilian Silurians hatched from egg s . ( PROSE : " Doctor Who and the Cave - Monsters " ) Third eye . Silurians of the " scholar caste " possessed a third eye on the forehead . ( COMIC : " The Lost Dimension " ) The three eyes provided them with a triple - faceted form of vision . ( TV : " Doctor Who and the Silurians " ) The third eye also allowed them to use a variety of telepathic powers . The Silurians used their third eyes to communicate with other Silurians in a process known as " linking " . The third eye would glow along with their emotions , becoming brighter when they were angry . They could sense the presence of other Silurians , even at great distances . Silurians could control the minds of other creatures . ( PROSE : " Blood Heat " ) They could hypnotise and coerce humans through a link to a primal part of a subject ' s mind , though stronger wills could resist this control . ( AUDIO : " Bloodtide " ) The third eye was capable of harming organic beings , killing them or leaving them unconscious . Alternatively , they could revive a human that they had rendered unconscious with the third eye . Energies emanating from it allowed them to burn through walls and create tunnels . ( TV : " Doctor Who and the Silurians " , PROSE : " Blood Heat " ) According to one account , the offensive capabilities of the third eye was a beam of burning radiation . ( COMIC : " Twilight of the Silurians " ) The Silurians also employed their third eye in less destructive tasks , such as activating their technology , opening passageways or creating forcefields to trap prisoners . ( TV : " Doctor Who and the Silurians " ) Not all Silurians had these third eyes , ( TV : " The Hungry Earth " ) primarily the ones belonging to the " warrior caste " . ( COMIC : " The Lost Dimension " ) Jastrok bitterly implied that these Silurians once had working third eyes but they had lost it over time . ( AUDIO : " Call to Arms " ) Cyber - conversion . On the prehistoric Earth , some Silurians were upgraded with cyber - technology , becoming Cyber - Silurian s . ( COMIC : " Supremacy of the Cybermen " ) Culture . The Silurians were generally a peaceful race . Their highest laws forbade outright warfare except for defence . ( TV : " Warriors of the Deep " ) There was also great importance placed on the species ' pure eugenics , which was believed to be their most important principle and most sacrosanct belief . Breeding between a Silurian and a Sea Devil was considered a crime punishable by death . The eggs of such a union were usually crushed and the parents executed . ( PROSE : " The Scales of Injustice " ) The Silurians were led by a Triad . ( TV : " Warriors of the Deep " , PROSE : " The Scales of Injustice " ) According to one account , the Triad were made up of the main leader , the " Second " and a Science Adviser . ( PROSE : " The Scales of Injustice " ) The majority of Silurian warriors appeared to be female , just as the females were the more aggressive in some species of lower reptile . ( TV : " Cold Blood " , " A Good Man Goes to War " ) Silurians communicated by telepathically linking through their third eyes , as well as by body language . Though they could use words , they generally only used speech for effect , when talking to children or to species without telepathic linking abilities . Silurians had little in the way of literature , since their mind linking abilities were a more effective method of transferring ideas . ( PROSE : " Blood Heat " ) A Silurian of advanced age would festoon the third eye with pearl s as a form of decoration . ( PROSE : " Blood Heat " ) Some Silurians kept early hominids as pets . ( PROSE : " Doctor Who and the Cave - Monsters " ) Whilst in the future , some used the term " Earth Reptiles " , others called themselves Silurians , insisting those that accepted the name of Earth Reptiles were pathetic assimilationists . ( PROSE : " Burning Heart " ) Around the 1970s , however , some Silurians , who wanted humanity to be wiped out , used the term Earth Reptiles to describe themselves by . ( PROSE : " The Scales of Injustice " ) They worshipped a Lizard God . ( PROSE : " The Crystal Bucephalus " ) Their myths included Urmungstandra , a devil god ( PROSE : " The Taking of Planet 5 " ) and the Great Old One s , including in their ranks Azathoth , a deity revered by the Silurians long before the rise of humanity . ( PROSE : " All - Consuming Fire " ) They wrote the Necronomicon . ( PROSE : " White Darkness " ) Madame Vastra swore by a Goddess . ( TV : " The Name of the Doctor " , " Deep Breath " ) The Third Doctor mentioned that along with literature , the Silurians had art , sport and games — a complete civilisation . ( PROSE : " The Scales of Injustice " ) Silurian poetry was composed of optical illusion s and mathematics . ( PROSE : " The Insidious Ideas of the Danger Thinkers " ) Relationship with other species . Humans . The Silurians did not think much of humans , considering them to be mere apes and despising them for destroying the terrestrial environment . ( TV : " Cold Blood " ) Humans had an instinctive fear of Silurians , known as the race memory malaise . ( PROSE : " Blood Heat " ) Technology . The Silurians made many advancements unknown to the human s . Genetic modification . The Silurians had advanced genetic capabilities . They brought species back from extinction , including many dinosaur s . ( PROSE : " Blood Heat " ) They could modify species , as they did with the Myrka . ( TV : " Warriors of the Deep " ) They created a genetically engineered plague , which they once used against early humans who invaded their crop settlements . This disease was highly virulent and was used as a form of " pest control " . ( TV : " Doctor Who and the Silurians " ) Despite this , they had problems with Silurian / Sea Devil hybrids ' deficiencies . ( PROSE : " The Scales of Injustice " ) They also altered primitive apes to make them breed more often and to improve their flavour when eaten ; using these techniques , they ultimately ended up creating the ancestors of humanity . ( AUDIO : " Bloodtide " ) The Silurians processed their own food and didn ' t rely on harvesting animals or plants ( PROSE : " The Scales of Injustice " ) except in times of famine . ( PROSE : " Blood Heat " ) The Silurians could bio - program soil , causing it to react to certain events and respond , generally by dragging people underground . ( TV : " The Hungry Earth " ) Medicine . They were capable of advanced decontamination , removing diseases and poisons from the body . ( TV : " Cold Blood " ) Weaponry . Silurians generally relied on their third eye for defensive purposes , using technology to enhance their power . ( PROSE : " Blood Heat " ) They used Silurian battlecruiser s , which were organic in structure , for transportation and offensive purposes . ( TV : " Warriors of the Deep " ) The Silurians found in Wales used guns reminiscent of Sea Devil guns which could fire fatal energy beams . They also wore armour and used special mask s that covered their faces and allowed them to scan objects . ( TV : " The Hungry Earth " / " Cold Blood " ) Miscellaneous technology . Silurians had cryogenic technology which they used to preserve their civilisation when they believed the Earth was in danger . ( TV : " Doctor Who and the Silurians " ) These had alarms for when the colony was threatened . ( TV : " The Hungry Earth " / " Cold Blood " ) They could use gravity bubble s to travel to and from the surface . ( TV : " The Hungry Earth " / " Cold Blood " ) They also had mechanical airships , which Bernice used and found to be of high quality . ( PROSE : " St Anthony ' s Fire " ) They had some holographic technology . ( PROSE : " The Scales of Injustice " ) They could modify the atmosphere , increasing the temperature in certain areas . ( PROSE : " Blood Heat " ) They had the ability to disperse the Van Allen belt using a molecular disperser , which would have left Earth defenceless against cosmic radiation in an attempt to exterminate humanity . ( TV : " Doctor Who and the Silurians " ) Silurians could create force field s to trap an entire village , controlling the amount of light that got in ( effectively making it night ) . ( TV : " The Hungry Earth " ) They also had wrist device s , ( TV : " Warriors of the Deep " ) and flew in aeroplane s ( PROSE : " Doctor Who and the Cave - Monsters " , " The Scales of Injustice " ) and sophisticated spaceship s . ( TV : " Dinosaurs on a Spaceship " ) Silurians also travelled in car s , ship s and submarine s . ( PROSE : " The Scales of Injustice " ) They invented candles which could induce lucid dream s , allowing people to communicate across time and space . ( TV : " The Name of the Doctor " ) They used sonic lantern s to corral dinosaur s . ( TV : " Deep Breath " ) History . Dominance . The Silurians were the original masters of Earth . ( TV : " Doctor Who and the Silurians " ) Both the Silurians and Sea Devils were led by the Triad , their " custodians " . ( TV : " Warriors of the Deep " ) In the early era of their rule , there were many stories of the rise of their civilisation . One noted legendary warrior chieftain was Masz K ' ll of the Third Dynasty , who fought against his evil alter - ego , the legendary Two - Faced Lizard . Another figure was Panun E ' Ni , who was the leader of the Southern Clan and conquered much of the world , which he ruled cruelly for a brief period until his defeat at the hands of Tun W ' lzz . Following that event , the previously imprisoned and cast out tribes came together in a new , more unified civilisation that ate their foes . Whether these were folk stories or historical facts was of no importance to them , as they inspired the Earth Reptiles for a millennium , with many of these writings left within their Hall of Heroes . ( PROSE : " The Scales of Injustice " ) In this era , the Silurians co - existed in groups of clans that lived alongside the original ape primitives that were developing on their planet . As a lesser species , these hominids became the primary livestock of the Silurians . In order to improve their flavour , a Silurian scientist by the name of Tulok began to genetically engineer the apes . This led to a faster breeding cycle as well as intelligence , creating early " Homo sapiens " . For his genetic crimes , the Silurians banished Tulok and his creations to die in the coming cataclysm . ( AUDIO : " Bloodtide " ) These primitive , ape - like men began to hunt in packs and attacked the Silurians . ( COMIC : " Twilight of the Silurians " ) They also began to prey on the crops of the Silurians , leading the Earth Reptiles to use plagues to exterminate them . ( TV : " Doctor Who and the Silurians " ) The Silurians were also afflicted by the plagues of the red leech . ( TV : " The Crimson Horror " ) At the height of their civilisation , the Silurians lived in cities of metal , and had uncontested dominion over the planet . ( COMIC : " Twilight of the Silurians " ) They had as many political factions as mankind would have . ( AUDIO : " Call to Arms " ) However , this era was cut short . Some of their scientists , such as Doctor Wolik , calculated that a small planetoid was destined to draw the atmosphere away from Earth when it passed very close to it , preventing the surface from being breathable , ( PROSE : " Doctor Who and the Cave - Monsters " , COMIC : " Twilight of the Silurians " ) wiping out " all life " . ( TV : " Doctor Who and the Silurians " ) Others , such as Nagara , believed it to be a simple scare story , while Soron ' s figures showed it would miss Earth completely , ( COMIC : " Twilight of the Silurians " ) although the government had ordered the construction of shelters where Silurians would remain in suspended animation ( PROSE : " Doctor Who and the Cave - Monsters " , COMIC : " Twilight of the Silurians " ) when the small planetoid first appeared . ( PROSE : " Doctor Who and the Cave - Monsters " ) The planetoid appeared either two ( PROSE : " Doctor Who and the Cave - Monsters " ) or twelve years before the great hibernation took place . ( PROSE : " The Scales of Injustice " ) Either way , the hibernation process took a while with different clans , sub - species , and factions hibernating at different times and places . ( AUDIO : " Call to Arms " ) The Third Doctor repeated the claim to Marc Marshall that the Silurians built the shelters when they thought the planet would " suck away " Earth ' s atmosphere as it rushed by . ( PROSE : " The Scales of Injustice " ) Conversely , the Fifth Doctor recalled that the Silurian astronomers predicted that Earth was about to be " struck " by the planet at the time , ( PROSE : " Warriors of the Deep " ) and the Eleventh Doctor described the trajectory of the planet the astronomers had predicted as a " crash course " . ( TV : " Cold Blood " ) When the planet was days away from causing the calculated catastrophe , the Silurians agreed to take refuge inside their shelters , so their civilisation could survive the coming disaster and reclaim their world once the danger had passed . ( PROSE : " Doctor Who and the Cave - Monsters " , COMIC : " Twilight of the Silurians " ) One group of Silurians decided to leave Earth in order to escape the disaster . Boarding the Silurian Ark , a spaceship carrying Silurians and several species of dinosaur , they placed themselves in suspended animation , with the ship programmed to bring them back to Earth long after the effects of the upcoming disaster had dissipated . ( TV : " Dinosaurs on a Spaceship " ) The Silurians were divided on the matter of a mating between the land castes and aquatic castes . Normally , such matings were forbidden , and any offspring were killed along with their parents . However , facing the threat of a global cataclysm , they allowed a colony of such hybrids to remain in their Shelter under the island of L ' Ithe . With the rest of the Silurian race , they took part in the great hibernation . ( PROSE : " The Scales of Injustice " ) The Silurians sealed themselves in their underground hibernation unit s , ( TV : " Doctor Who and the Silurians " ) along with a male and female of all the more useful reptile animals , ( PROSE : " Doctor Who and the Cave - Monsters " ) and planned to suspend their lives until the atmosphere returned , ( TV : " Doctor Who and the Silurians " , COMIC : " Twilight of the Silurians " ) by using a device on the ground above each shelter containing the hibernation units which would automatically trigger a massive amount of electricity to wake the Silurians once the atmosphere returned to normal . ( PROSE : " Doctor Who and the Cave - Monsters " ) However , they were unaware the dangerous planetoid that they predicted would draw away the atmosphere was instead drawn into Earth ' s orbit and became the Moon . As a result , the Silurians were never revived , as the atmosphere was not drawn away for it to return to the planet . ( TV : " Doctor Who and the Silurians " ) Although the atmosphere was never completely drawn off and the creatures on the surface did not suffocate , many mammal ian life forms perished , while others survived , due to the great forces caused by the Moon ' s appearance creating cyclones and tidal waves . ( PROSE : " Doctor Who and the Cave - Monsters " ) During millions of years of hibernation , the reactivation machinery of the hibernation units deteriorated . ( TV : " The Sea Devils " ) Despite their intentions to punish Tulok , the renegade Silurian scientist instead sabotaged a number of the hibernation chambers and destroyed them . ( AUDIO : " Bloodtide " ) The Arkive tried to attract the Silurians to Saturn in order to repair itself . Though the Silurians noticed one of Saturn ' s moons being destroyed , they were too busy preparing for the disaster to investigate . ( PROSE : " The Wheel of Ice " ) Awakenings . Over the millions of years since their rule , many of the Silurians ' prominent structures such as the Hall of Heroes were lost to erosion and plate movement which erased any traces of their ancient civilisation . ( PROSE : " The Scales of Injustice " ) After millions of years , some of the Silurian hibernation unit s were activated and opened . In 102 , a number of Silurians were part of the Alliance of the Doctor ' s worst enemies that imprisoned the Eleventh Doctor in the Pandorica . ( TV : " The Pandorica Opens " ) Charles Darwin and the HMS " Beagle " expedition , along with the Sixth Doctor and Evelyn Smythe , encountered a rogue Silurian group in the Galápagos Islands . The leader of this group was Tulok , responsible for creating humanity ' s prehistoric ancestors via a forbidden breeding program . ( AUDIO : " Bloodtide " ) Prior to 1888 , a group of Silurians was awoken by the digging of the London Underground . This led to the death of several navvies . Vastra , a skilled Silurian warrior who had been awoken by their digging , wanted revenge . The Doctor convinced her to live peacefully in London . In 1888 she resided with her human partner Jenny , although she fed on human criminals . Then , she and several of her soldiers were called up by the Doctor to fight at the Battle of Demon ' s Run . ( TV : " A Good Man Goes to War " ) Vastra subsequently became the leader of the Paternoster Gang , protecting the Earth of that era from threats . ( TV : " The Snowmen " , " The Crimson Horror " , " The Name of the Doctor " , " Deep Breath " ) In 1892 , the Silurians led by their leader Vekkis found a piece of the Eternity Clock to reclaim Earth . They planned to use the power of the Clock to pump toxin to wipe out the human race . The Eleventh Doctor and River Song destroyed the toxin and took the Eternity Clock . ( GAME : " The Eternity Clock " ) Jules Verne and the Doctor once encountered Silurians and a giant squid . This incident was worked into " 20 , 000 Leagues Under the Sea " , though the Doctor had some difficulties convincing Jules to remove the parts with the Silurians . ( PROSE : " Peacemaker " ) In 1903 , after receiving a wealth of information from the future , Grigori Rasputin saw beings which lived beneath the surface of the Earth . ( AUDIO : " The Wanderer " ) In the late 20th century a group of Silurians were awakened from hibernation by the energy from the nearby nuclear power research centre at Wenley Moor . After disagreement between Okdel L ' da and Morka over a course of action , Morka won out , killing Okdel , and the Silurians tried to reclaim the planet from human ity by releasing a deadly virus . This plan was prevented by Dr Liz Shaw of UNIT and the Third Doctor , when they had the cure mass - produced . After this plan was thwarted , they tried using their molecular disperser to destroy Earth ' s van Allen belt , so that the sun ' s radiation would burn the humans to death while allowing the cold - blooded Silurians to survive , but Liz and the Doctor stopped them again when they overloaded the disperser and the facility ' s reactor . Despite the Doctor ' s best efforts to broker a peaceful solution , the Silurian base was bombed by UNIT by order of Brigadier Lethbridge - Stewart . ( TV : " Doctor Who and the Silurians " ) While the third and eleventh incarnations of the Doctor stated in some accounts that this tribe had all died , ( TV : " Doctor Who and the Silurians " , " Cold Blood " ) according to another account , the Third Doctor said they were only entombed . ( PROSE : " The Scales of Injustice " ) Shortly afterwards , a second base was awoken in Oregon , and was likewise dealt with by UNIT . ( PROSE : " The Devil Goblins from Neptune " ) Following this , the Silurian - Sea Devil hybrids Baal D ' jo and Tahni kidnapped the human boy Marc Marshall , and took him to their shelter under the island of L ' Ithe to experiment on him . They intended to prolong the hybrids ' short lifespan , but Baal later allowed Marc to be returned to the British mainland when Marc ' s presence in the shelter no longer suited the hybrids . When the shelter ' s leader Chukk was killed by a C19 agent , Baal and Tahni ' s power - hungry mother Auggi D ' jo took over and intended to take back Earth from humanity . Her fleet was pushed back by UNIT on the Kent coast . Baal and Tahni took over the shelter , while Auggi escaped in her battlecruiser . Liz offered to continue to help the hybrids find a cure for their condition . ( PROSE : " The Scales of Injustice " ) In the aftermath of Wenley Moor , UNIT began a search for any other colonies using a device invented by the Doctor . Mike Yates was involved while Benton trooped around the country . Standard protocols were to keep an eye on the Silurians and make sure they stayed asleep and alive . Some colonies would awaken over time but , when seeing how many humans there were , opt to return to hibernation . ( AUDIO : " Call to Arms " ) In 1983 , Sarah Jane Smith and K9 , while visiting Warren Martyn ' s archaeological expedition in Egypt , discovered an underground city of Silurians and Sea Devils . Sarah Jane opened diplomatic relations with them . On her return to England , she contacted the Brigadier , who wished to make amends for his earlier mistakes . ( COMIC : " City of Devils " ) By 2003 there were Silurians serving as part of UNIT , in particular Imorkal , who worked with Liz at Tranquillity Moonbase located on Earth ' s Moon . ( PROSE : " Eternity Weeps " ) Some years later , Sir Alistair helped the Silurians try to finally make peace with the humans , though the general public believed it to be a stunt involving men in rubber suits . ( AUDIO : " The Coup " ) Later , the Silurians aided UNIT in finding a cure for a plague . ( AUDIO : " The Wasting " ) In late 2010 , a fossilised Silurian egg was discovered by the Pharos Institute . Sarah Jane went to the institute to take a look at it . ( TV : " Sarah Jane ' s Alien Files episode 6 " ) In the 2010s , a Silurian was a resident of the hidden trap street in London which housed lost aliens on Earth under the protection of Mayor Me . As with the rest of the inhabitants it appeared cloaked in human form through use of the lurkworm s . ( TV : " Face the Raven " ) In 2020 , a Silurian city in Wales was awoken by a mining trial led by Nasreen Chaudhry and Tony Mack . ( TV : " The Hungry Earth " ) The giant drill had attacked the Silurians ' oxygen pockets . ( TV : " Cold Blood " ) The Silurians took corpses from a graveyard for study , as well as Mo Northover and later Amy Pond as living subjects . Eventually they contained the village in a force field and captured Elliot Northover . Alaya came to the surface and was captured . While the Eleventh Doctor and Nasreen travelled to the Silurian city to negotiate her return for Mo , Elliot and Amy , Alaya was guarded by Tony , Rory Williams and Ambrose Northover . ( TV : " The Hungry Earth " ) The Eleventh Doctor and Nasreen were captured , while Amy and Mo escaped . After an abortive rescue attempt , the Doctor was able to convince the Silurian leader , Eldane , to negotiate with Amy and Nasreen for the future of both their races . Back on the surface , Ambrose tried to help her family and threatened Alaya , accidentally killing her just as the group were summoned to the city . She also set the drill to start burrowing again in fifteen minutes . Alaya ' s death , and Ambrose ' s threat to the city , was received badly , especially by Alaya ' s sister , Restac , who tried to kill all the humans in retribution . Eldane managed to lead the Doctor and his friends to a laboratory . He released a deadly gas into the city , forcing Restac ' s troops to return to their hibernation . The Doctor stopped the drilling by destroying the drill with an energy pulse , which also sealed off the city in a cave - in . The timer was set for a thousand years to permit a second chance at negotiation . ( TV : " Cold Blood " ) Circa 2084 , a group of Silurians allied themselves with the Sea Devil s to invade Sea Base 4 . They attempted to launch nuclear weapon s to provoke a war between the two major power blocs . They were killed when the Fifth Doctor , perceiving no more peaceful option , flooded hexachromite gas in order to kill them . ( TV : " Warriors of the Deep " ) Post - contact . At some point after the 2084 incident , a human colony faced a devastating war against the Earth Reptiles . Humans developed a doomsday device which they placed in a base around the moon colony , designed to scour the surface of the satellite . To combat this , the Earth Reptiles dispatched Quarra to infiltrate the base and take it over . However , she was unaware of an entertainer called Jen Yates who was not on the crew count , and this last survivor managed to activate the weapon , killing everyone in the colony . Though Quarra killed Jen , the shock of the event led to Quarra taking on the entertainer ' s personality to shield her from the truth . She believed that she was now human and that she was guarding the weapon alone in case the Earth Reptiles won the war . After a visit by the Seventh Doctor , Quarra remembered the past and killed herself by walking onto the surface of the moon without a spacesuit . ( PROSE : " Cold War " ) In 2367 , Solomon sent a distress signal to the Silurian Ark . Realising that there were valuable dinosaurs on board , he and his robots slaughtered the Silurian crew . Unable to pilot the ship to his destination as it required two pilots with the same gene - chain , the Ark headed back to Earth where it was detected by the ISA . The Doctor formed a gang to investigate the ship after learning of the situation and to save the ship from being shot down by the ISA . As the ship came under threat of destruction , it was piloted to safety by Brian and Rory Williams who had the same gene - chain as they were father and son while the missiles were tricked into destroying Solomon ' s ship instead . In the aftermath , the dinosaurs were taken from the Ark and transported to a new home on Siluria by the Doctor and Brian . ( TV : " Dinosaurs on a Spaceship " ) By the 26th century , the inter - species conflicts appeared to have come to an end . Silurians and Sea Devils were accepted into Earth society , and the term " Earth Reptile " was apparently popularised among humans . ( PROSE : " Love and War " ) During the 29th century , when solar flares were threatening to engulf the Earth , the Silurians built a spacecraft , surreptitiously attaching it to the bottom of the humans ' own . After takeoff , a Dalek attack caused the Silurian ship to break away from the humans . ( GAME : " Evacuation Earth " ) In the 30th century , the Earth Reptiles were part of the Earth Empire , considered full members of the government as an Earthborn species . ( PROSE : " So Vile a Sin " ) In the year 3020 , one thousand years after the encounter at Cwmtaff , Eldane ' s clan were scheduled to reawaken and unite with human ity and their Earth Reptile cousins . ( TV : " Cold Blood " ) In the 32nd century , it became illegal to trade in Earth Reptile pituitary analogue extract on the planet Dramos . ( PROSE : " Burning Heart " ) In 3110 , a Silurian was running the Musée d ' Orsay when the Eleventh Doctor visited it . ( PROSE : " The War of Art " ) Around the 52nd century , a group of armed Silurian warriors resembling those from Wales were called upon by the Eleventh Doctor to help him in the Battle of Demon ' s Run to rescue Amy Pond . Many of these Silurians were killed by the Headless Monks . ( TV : " A Good Man Goes to War " ) In the 91st century , a Silurian actor starred as the protagonist of a film adaptation of H . G . Wells ' " The Time Machine " spoken in haiku . ( PROSE : " Synthespians™ " ) In the 101st century , the Earth Reptiles were part of the Union . ( PROSE : " The Crystal Bucephalus " ) Parallel dimensions . When Avalon was created as a shelter for the Catuvellauni , some Silurians were unintentionally brought there as well . Their descendants were known as the Fair Folk . ( PROSE : " The Shadows of Avalon " ) The Silurians of Mondas . Lizard King s were the Mondas ian counterparts of the Silurians , much as human s and the Mondasian s were identical . ( COMIC : " The Dead Heart " ) Behind the scenes . Dating issue . The era of the Silurians have never been consistently or clearly dated . Naming issue . Another name given in " Blood Heat " , " Psionosauropodamorphae " , translates as " psychic lizard - foot shaped " . This may be intended to suggest a connection between the Silurians and the sauropod family of dinosaurs , though this seems unlikely given the near - total lack of physical resemblance and the comparatively small cerebral capacity of most sauropod dinosaurs . " Homo reptilia " , one of the suggested names used in " Doctor Who and the Cave - Monsters " , " City of Devils " , " The Hungry Earth " / " Cold Blood " and " Dinosaurs on a Spaceship " , cannot be a scientific term . The rules governing the use of prevent any two separate groups within a kingdom ( " i . e . animals " ) from using the same genus .
