A chimaeroid mandibular dental plate from the nearshore upper Oligocene Sooke Formation west of Victoria, Vancouver Island, British Columbia, is described here as a new genus of chimaerid fish (Holocephali, Chimaeridae), Canadodus suntoki, gen. et sp. nov. The new genus differs from mandibular plates of both Recent and Cenozoic Chimaeridae (Chimaera, Hydrolagus) in having a more robust plate with a massive symphyseal tritor filled by laminated whitlockin, the presence of a large compound median tritor and a small inner tritor, as well as the absence of solid whitlockin in the dental structure. The chimaerid individual is estimated to have measured nearly 1 m in total body length. This is a first record of a Paleogene chimaeroid fish in both British Columbia and Canada and only the second record from the Oligocene of the northern Pacific. In addition, the species Chimaera gosseleti Winkler, 1880, is transferred to the genus Harriotta, resulting in the new combination Harriotta gosseleti (Winkler, 1880).

来自不列颠哥伦比亚省温哥华岛维多利亚市以西的近岸上渐新世苏克岩层的下颌骨下颌盘状牙板在这里被描述为新的类ma科鱼类（Holocephali，Chimaeridae），Canadodus suntoki，gen。等。十一月 新属与最近的和新生代的ma科（Chimaera，Hydrolagus）的下颌板不同。）在具有更坚固的钢板的情况下，该钢板具有由叠层的whitlockin填充的巨大的共生三叉戟，在牙齿结构中存在较大的复合正中Tritor和较小的内部Tritor，并且没有固体whitlockin。据估计，该类哺乳动物的总身长约为1 m。这是不列颠哥伦比亚省和加拿大的古近代类chi鱼的第一个记录，也是北太平洋渐新世的第二个记录。此外，物种Chimaera gosseleti Winkler（1880年）被转移到Harriotta属中，形成了新的Harriotta gosseleti组合（Winkler，1880年）。
