Abstract The Pachyrhinosaurus lakustai quarry on Pipestone Creek near Grande Prairie, Alberta, Canada, is a monodominant bone bed with well-preserved fossil bones that are predominantly completely disarticulated. Nearly every element within the skeleton is represented. Identified bones were grouped by transportability of the bones present using a previously published classification system. Just over 70% of the bones were classified within the most transportable group, indicating a fluvial allochthonous accumulation. Orientations produced by utilizing the bone bed maps indicate that there is no single directionality to the bones.
