For the purposes of this list, a "Homo Reptilian story" is one in which one living, authentic Silurian or Sea Devil plays a part within the confines of the story, outside of flashbacks to previous stories and cliffhangers that lead into the following story. Stories like Frontier in Space, The Pandorica Opens and The Wedding of River Song are also not included due to Homo Reptilians' cameos being of little consequence to the plot of the story. Stories featuring MadamVastra of the Paternoster Gang are only included on the Paternoster Gang story template.
