Ventral Thoracic Neuromast Lines of Placoderm Fishes
Nature, 1965IN the past forty years, following Stenso's1 pioneer work on the arthrodire Macropetalichthys, much information has come to light in support of the view that the Palaeozoic placoderms and the still surviving elasmo-branchs and holocephalians are more closely related to each other than to any other group of fishes2.

Placoderm fishes: diversity through time
1991Abstract The placoderms, with 250 genera, constitute a small but much diversified group of bony fishes. They are sometimes classified as stem-group osteichthyans and, together with the acanthodians, are the earliest true jawed fishes. They are found in the mid-Silurian, but flourished in the Devonian reaching their greatest diversity in ...

Placoderm branchial and hypobranchial muscles and origins in jawed vertebrates
Journal of Vertebrate Paleontology, 2003Abstract Muscle morphology in the Placodermi can be inferred by comparison to extant gnathostomes (Chondrichthyes (Actinopterygii + Sarcopterygii)). Examination of the chondrichthyan hypobranchial musculature suggested a comparable musculature for placoderms, including the coracomandibularis and coracohyoideus, acting separately to depress the mandible
