What is "asprosaurus"

Asprosaurus is an extinct genus of anguimorph lizard from the Late Cretaceous of South Korea. Named in 2015 from the Boseong Bibong-ri Dinosaur Egg Site, the type species Asprosaurus bibongriensis is the first Mesozoic lizard to have been discovered on the Korean peninsula. Because Asprosaurus is known only from fragmentary material, its relationships with other lizards are uncertain. However, features of the lower jaw suggest that it may be a member of a clade (evolutionary grouping) called Monstersauria, which includes the living Gila monster.
