Tubonasus (meaning “tube nose”) is an extinct monospecific genus of long-snouted [1] arthrodire placoderm from the Early Frasnian stage of the Late Devonian period, found at the Gogo Formation of Kimberley, Western Australia.
Tubonasus is interpreted as a pelagic pursuit predator, and had the ability of swallowing prey whole. Like other camuropiscids, it has an elongated rostrum, streamlined body, and narrow infragnathals. [2]
Tubonasus is a member of the family Camuropiscidae under the superfamily Incisoscutoidea, which belongs to the clade Coccosteomorphi, one of the two major clades within Eubrachythoraci. [3] [4] The cladogram below shows the phylogeny of Tubonasus: [4]
