[1] The type specimen of Helioscopos, given the designation DINO 15914 (previously DNM 15914), was discovered at Dinosaur National Monument from a locality called "Quarry #317".

[2] However, the specimen was re-examined in 2023 by a team of authors including Dalton Meyer, Chase Brownstein, Kelsey Jenkins, and Jacques Gauthier in the same publication that they named the new genus Limnoscansor.

[1] The genus name also mirrors the extant lizard species Phrynocephalus helioscopus (commonly called the "sunwatcher").

[1] In their description of Helioscopos, Meyer and colleagues conducted a phylogenetic analysis to determine the evolutionary relationships of the new taxon.
