Late Silurian

Late Silurians were a Silurian subspecies identified by historians who had been allowed access to the "Monster Vaults" of the databanks in the Doctor's TARDIS. (PROSE: ) One such Silurian, Vastra, was identified on sight as a warrior by Early Silurians, who she recognised as being of the "scholar caste". (COMIC: )

History
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: )

In the 2010s, a masked 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 lurkworms. (TV: )

In 2020, a Silurian city in Wales was awoken by a mining trial led by Nasreen Chaudhry and Tony Mack. (TV: {{cs|The Hungry Earth (TV story){{) The giant drill had attacked the Silurians' oxygen pockets. (TV: {{cs|Cold Blood (TV story)}}) 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: {{cs|The Hungry Earth (TV story)}}) 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: {{cs|Cold Blood (TV story)}})
