Fallacosteus is an extinct monospecific genus of arthrodire placoderm from the Early Frasnian stage of the Late Devonian period, found at the Gogo Formation of Kimberley, Western Australia. As with almost all other camuropiscids, F. turneri had an elongated snout that may have enhanced its hydrodynamic streamlining.[1][2]
Etymology
[edit]The generic name translates as "deceptive bone," in reference to its extreme similarity to Camuropiscis. The specific name turneri honors Sue Turner.[1]
Phylogeny
[edit]Fallacosteus 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 Fallacosteus:[4]
