What is "kryptops"

Kryptops (meaning "covered face", in reference to evidence that the face bore a tightly-adhering covering) is a genus of theropod dinosaur from the Early Cretaceous of Niger. It is known from a partial skeleton found at the Gadoufaoua locality in the western Ténéré Desert, in rocks of the Aptian- Albian age Elrhaz Formation. This dinosaur was described by Paul Sereno and Stephen Brusatte in 2008, with a single species to date: the type species K. palaios ("old").
