Titanokorys[1] is a genus of extinct hurdiid (peytoiid) radiodont (a grouping of primitive stem arthropods which lived during the early Paleozoic) that existed during the mid Cambrian.

[1][4] Titanokorys is distinguished from other Burgess Shale radiodonts because of its large anterior sclerite(head covering carapace, or H-element) and a pair of spines on the anteroventral sides.

The species name "gainesi" honors the American geologist Robert R. Gaines, who was instrumental in the discovery of new fossil deposits in the Burgess Shale in 2012.

[1] This study was based on twelve specimens that came from the Marble Canyon area of Tokumm Creek in the northern part of Kootenay National Park in British Columbia.

[1] Only disarticulated head sclerites, frontal appendages and oral cone (radiodont mouthpart that somewhat resembled a camera aperture[7]) have been discovered.

Hurdiids can be distinguished from other radiodonts by the rake-like frontal appendages which each bore a single row of elongated endites with only anterior auxiliary spines, alongside the combination of enlarged head sclerites and tetraradial mouthparts (oral cone).

[1] It is presumed that the animal dug up the sediment with its huge protruding carapace and guided the prey into its mouth with the front appendages to form a cage-like structure.

[1] Titanokorys is a relatively rare find at Marble Canyon, because of this it is thought that this fossil site possibly occurred near the edge of the species range in life.

[1] Due to the depth of the Marble canyon site In comparison to the Cathedral Escarpment, Titanokorys, and the contemporary fauna most likely inhabited a mesopelagic environment.

The fauna in the region included the hymenocarine pancrustaceans such as Tokummia and Balhuticaris, the primitive chordate Metaspriggina, and the isoxyid arthropod Surusicaris.
