- When Albertadromeus was named, Brown and others additionally named a brand new subfamily, Orodrominae, for thescelosaurids extra intently associated to Orodromeus than Thescelosaurus (group consists of Oryctodromeus)
- Thescelosaurids are neornithischians that lived within the Early to Late Cretaceous in Asia and North America. A couple of of them are identified to be burrowers
