Bugenasaura infernalis

Bugenasaura was a plant-eating dinosaur from the famous Hell Creek Formation of South Dakota, and although modestly-sized it was big enough to cause something of a stir. It was initially described as an "unidentified species of Thescelosaurus" in 1976 by William J. Morris who interpreted deep ridges on its jaws as large cheek attachment points, and these, plus a flared out beak, are what Peter Galton pounced on when he christened this specimen the "large-cheeked lizard" in 1995.
Clint Boyd revisited the now-named Buganasaura in 2009 and described it as wonderful. However, he was talking about Thescelosaurus — "the wonderful lizard" — and he handed the remains back to their rightful owner. Bugenasaura infernalis is now Thescelosaurus again, but not a unique species of it.
Etymology
Buganasaura takes its name from the Latin "Bu" or possibly the Greek "bou" (both words mean "huge") plus the Latin "gena" (cheek) and the Greek "saura" (female form of lizard).
The species epithet, infernalis, is derived from the Latin "infernus" (the lower regions, aka hell), which is a reference to its discovery in the Hell Creek Formation.
Discovery
The remains of Bugenasaura were discovered in the Hell Creek Formation of Harding County, South Dakota, USA. The fossils which formed the holotype (SDSM 7210) consisted of a partial skull, two partial vertebrae, and two finger bones.
