Uquiasaurus is an extinct genus of iguanian lizards represented by the type species Uquiasaurus heptanodonta from the Late Pliocene of Argentina. Uquiasaurus was first described in 2012 on the basis of isolated snout and jaw bones within the , the namesake of the genus. These bones were preserved in a midden of predatory bird pellets and are part of a microvertebrate assemblage that includes the bones of rodents, marsupials, frogs, birds, and other lizards, one of the few to document the mixing of North and South American faunas during the Great American Interchange. Phylogenetic analysis indicates that Uquiasaurus is part of a clade (evolutionary grouping) of iguanians that includes the living families Liolaemidae, Leiocephalidae, and Tropiduridae. Below is a cladogram from Daza et al. (2012) showing its phylogenetic relationships:[1]
