Stenotholus

narrow dome

• stenos · Greek · narrow
• tholos · Greek · dome

The name combines the Greek words for "narrow" and "dome" (tholos), referring to the relatively narrow, domed skull roof of this bone-headed dinosaur. The genus was erected for a species originally described as Stegoceras kohleri, and the dome shape was one of the features used to separate it from Stegoceras.
