Canadaga (meaning "Canadian bird"[1]) is aflightless birdgenus from the LateCretaceous. The single knownspecies isCanadaga arctica. It lived in the shallow seas around what today isBylot andDevon Islands inNunavut,Canada. Its fossils were found in rocks dated to theCampanian[2] to mid-Maastrichtian age, about 67 million years ago.[3] It was found in theKanguk Formation
It was a member of theHesperornithes, flightless toothed seabirds of theCretaceous. Among these, it belonged to theHesperornithidae, along withHesperornis, the well-known namesake genus.[4]
C. arctica is one of the largest known members of the Hesperornithes, reaching a length of 2.2 metres (7.2 ft).[2] It also represents one of the last known members of the lineage.[1] Unlike its relatives which are mainly known from subtropical or tropical waters, this species seems to have ranged in temperate or evensubarctic areas.
The species is described from 3 associated cervical vertebrae, one caudal vertebra and twofemurs.[3]
