New information on Brindabellaspis stensioi Young, 1980, highlights morphological disparity in Early Devonian placoderms [PDF]
Royal Society Open Science, 2018 Acid-prepared specimens of the placoderm Brindabellaspis stensioi (Early Devonian of New South Wales, Australia) revealed placoderm endocranial anatomy in unprecedented detail.

Early Gnathostome Phylogeny Revisited: Multiple Method Consensus. [PDF]
PLoS ONE, 2016 A series of recent studies recovered consistent phylogenetic scenarios of jawed vertebrates, such as the paraphyly of placoderms with respect to crown gnathostomes, and antiarchs as the sister group of all other jawed vertebrates.

Placoderms from the Lower Devonian “placoderm sandstone” of the Holy Cross Mountains, Poland with biostratigraphical and palaeobiogeographical implications [PDF]
Acta Palaeontologica Polonica, 2017 The siliciclastic sequence of the Lower Devonian of the southern part of the Holy Cross Mountains in Poland is renown for abundant vertebrate fossils, including ostracoderm, sarcopterygian, acanthodian, chondrichthyan, and placoderm remains. Study of the

New findings in a 400 million-year-old Devonian placoderm shed light on jaw structure and function in basal gnathostomes [PDF]
Scientific Reports, 2017 Arthodire placoderms have been proposed as the sister group of Chinese ‘maxillate’ placoderms plus all the more crownward gnathostomes. These basal groups provide key information for understanding the early evolution of jaws.

Reappraisal of the Silurian placoderm Silurolepis and insights into the dermal neck joint evolution [PDF]
Royal Society Open Science, 2019 Silurolepis platydorsalis, a Silurian jawed vertebrate originally identified as an antiarch, is here redescribed as a maxillate placoderm close to Qilinyu and is anteroposteriorly reversed as opposed to the original description.

Ecomorphological inferences in early vertebrates: reconstructing Dunkleosteus terrelli (Arthrodira, Placodermi) caudal fin from palaeoecological data [PDF]
PeerJ, 2017 Our knowledge about the body morphology of many extinct early vertebrates is very limited, especially in regard to their post-thoracic region. The prompt disarticulation of the dermo-skeletal elements due to taphonomic processes and the lack of a well ...

Vascularization and odontode structure of a dorsal ridge spine of Romundina stellina Ørvig 1975. [PDF]
PLoS ONE, 2017 There are two types of dermal skeletons in jawed vertebrates: placoderms and osteichthyans carry large bony plates (macromery), whereas chondrichthyans and acanthodians are covered by small scales (micromery).
