The collection of this bone was part of an operation by the Southeast Sichuan Geological Team to salvage paleontological materials during construction in a residential area, and it is now accessioned in the Chongqing Municipal Bureau of Planning and Natural Resources.

[1] The specimen was first mentioned in a paper describing the fossil assemblage of the type locality (named the Yuzhou Biota), which represents a lacustrine ecosystem.

[2] After being announced in December 2024 as a non-finalized preprint, Yao et al. (2025) described Archaeocursor asiaticus as a new genus and species of early ornithischians based on this fossil specimen.

[1] Using histological methods, Yao et al. (2025) determined that the holotype femur likely belonged to an early adult individual that had not yet reached somatic maturity.

[1] In their phylogenetic analyses, Yao et al. (2025) recovered Archaeocursor as an early-diverging member of the Ornithischia, branching crownward of heterodontosaurids as the sister taxon to Eocursor.
