With his 2014 assignment of skull CMN 8801 to Kosmoceratops sp. and his naming of a new species of Pentaceratops (P. aquilonius), both from the Dinosaur Park of Alberta, Longrich argued against the idea of distinct northern and southern dinosaur provinces, since the two genera were now known from both southeastern and northern North America.
