| rdfs:comment | - Coronosaurus is known from two bone beds located in the upper unit of the Oldman Formation, of the Belly River Group. Most of the ceratopsid material, if not all, from BB 138 in Dinosaur Provincial Park, Alberta, and the MRR BB near Warner, Alberta, was referred to C. brinkmani. Bone bed 138 is located approximately fifty kilometers from Brooks, Alberta, in the Oldman Formation and 14.6 m below the contact with the Dinosaur Park Formation. It was excavated by Philip Currie between 1996 and 2000.[3] The MRR BB located approximately 180 km southwest of BB 138, is also from the Oldman Formation. These bone beds date to the middle Campanian stage of the Late Cretaceous period.[1] Both the specimens and the precise localities are archived at the Royal Tyrrell Museum of Palaeontology, in Drumhel

| abstract | - Coronosaurus is known from two bone beds located in the upper unit of the Oldman Formation, of the Belly River Group. Most of the ceratopsid material, if not all, from BB 138 in Dinosaur Provincial Park, Alberta, and the MRR BB near Warner, Alberta, was referred to C. brinkmani. Bone bed 138 is located approximately fifty kilometers from Brooks, Alberta, in the Oldman Formation and 14.6 m below the contact with the Dinosaur Park Formation. It was excavated by Philip Currie between 1996 and 2000.[3] The MRR BB located approximately 180 km southwest of BB 138, is also from the Oldman Formation. These bone beds date to the middle Campanian stage of the Late Cretaceous period.[1] Both the specimens and the precise localities are archived at the Royal Tyrrell Museum of Palaeontology, in Drumheller, Alberta. The holotype of Coronosaurus is TMP 2002.68.1. It is a large adult-sized parietal with an almost complete midline bar and a partial posterior bar with left P1–P3 processes and the partially eroded right P1-P2. The specimen lacks the extreme anterior margin of the midline bar that forms the posterior wall of the frontal fontanelle and the paper-thin lateral margins that define the medial margins of the supraorbital foramina. Other significant specimens according to Ryan & Russell (2005) include TMP 2002.68.3 (a parietal), TMP 2002.68.10 (a postorbital), and TMP 2002.68.5 (supraorbitals).
