Laquintasaura is a genus of Venezuelan ornithischian dinosaur containing only the type species Laquintasaura venezuelae. The species is the first dinosaur to have been discovered in Venezuela.[1][2][3] Found in the Lower Jurassic, Hettangian, La Quinta Formation from which it takes its name, the bipedal species was about a meter long and 25 centimeters high.[2][4] L. venezuelae, which is believed to have lived in herds,[5] was primarily herbivorous, although it may have also eaten large insects and other small animals.[4][6]

A phylogenetic analysis by Baron et al. (2017) recovered Laquintasaura as the sister-taxon to Scutellosaurus, within the clade Thyreophora.[7]
