Atlascopcosaurus (/ˌætləsˌkɒpkəˈsɔːrəs/) is a genus of herbivorous basal iguanodont dinosaur from the Early Cretaceous Eumeralla Formation of Australia.

[1] The type specimen, NMV P166409, was found in 1984 at the Dinosaur Cove East site on the coast of Victoria, in layers of the Eumeralla Formation dating from the early Cretaceous, Aptian-Albian.

[1] Although the rest of the skeleton is unknown it can be inferred from closely related species that the genus represents a small bipedal herbivore.

The specific name, loadsi, honours William Loads, the state manager for Atlas Copco at the time, who assisted during the dig.

[2] Because the teeth are not species-specific and the maxilla fragment is little informative, Agnolin et al. (2010) treated it as a nomen dubium, even though they noted similarities with the elasmarians Anabisetia and Gasparinisaura from Patagonia.
