Cyber-dinosaur

Cyber-dinosaurs were species of different types of dinosaurs subjected to partial cyber-conversion. They were created by the Cyber-Silurians. (COMIC: Supremacy of the Cybermen)

Some dinosaur species, such as Triceratops, were used by Cyber Silurians as mounts. Others, such as Tyrannosaurus rex, were used for combat. Pterosaurs were deployed inside Cyber-Arks to spread technology to other planets. Unlike those used the Silurians, the cybernetics could be affected by a sonic screwdriver.

Similarly, there have been dinosaurs on Mondas that were cyber-converted by the Mondasian equivalent of the Silurians called the Lizard Kings. (COMIC: The Dead Heart)
