Rutiotomodon is an extinct genus of trilophosaurid allokotosaur from the Middle Triassic of Germany.

It is known from two jaw fragments: a right maxilla and a referred partial dentary that bears similarities to that of Trilophosaurus buettneri.

'Tytthos' is the Greek for small (a reference to its diminutive size of 50cm long) thus making the name for this species (Rutiotomodon tytthos) mean 'small wrinkled cut tooth.

[1] In an analysis that was part of the species being named, Rutiotomodon was found to be more derived than Teraterpeton, in an unresolved polytomy with Coelodontognathus, which was recovered as a trilophosaurid.

[1] Sues has suggested that Rutiotomodon may have had a small beak whilst the jaws had tightly packed teeth with broad crowns for crushing plant matter.
