Fragmentary but associated dinosaur bones collected in 1930 fromthe Pine River of northeastern British Columbia are identified here asoriginating from an ankylosaur. The specimen represents only the secondoccurrence of dinosaur skeletal material from the Cenomanian DunveganFormation and the first from Dunvegan outcrops in the province of BritishColumbia. Nodosaurid ankylosaur footprints are common ichnofossils in theformation, but the skeletal material described here is too fragmentary toconfidently assign to either a nodosaurid or ankylosaurid ankylosaur. TheCenomanian is a time of major terrestrial faunal transitions in NorthAmerica, but many localities of this age are located in the southern UnitedStates; the discovery of skeletal fossils from the Pine River demonstratesthe potential for the Dunvegan Formation to produce terrestrial vertebratefossils that may provide important new data on this significant transitionalperiod during the Cretaceous.
