[7] Finlayson made a guest appearance as herself, in the episode 48 ("Das dunkle Geheimnis der Neandertaler", 2012) of the first season of the Austrian television series Terra Mater.

She explained to journalists that Gibraltar was once "a Mediterranean Serengeti" where "deer, wild horse and cattle grazed on the savannahs and were stalked by a strange mix of predators that included Spotted Hyaenas, Leopards, Brown Bears, Wolves and Lynxes.

In short, the message was "that the Neanderthals were 'thinking people' and that they were able to extract from the environment," for example "by cutting the feathers and inner bones from the birds of prey they captured, leaving them with the outer shell, and using them as ornaments as has been the case in other cultures across the world.
