It was a member of the Hesperornithes, flightless toothed seabirds of the Cretaceous. Among these, it belonged to the Hesperornithidae, along with Hesperornis, the well-known namesake genus.^[4]

Description

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 even subarctic areas.

The species is described from three associated cervical vertebrae, one caudal vertebra and two femurs.^[3]
