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]

Phylogeny

[edit]

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]
