How big can a walking fish be? A theoretical inference based on observations on four land‐dwelling fish genera of South Vietnam [PDF]
Integrative Zoology, Volume 17, Issue 5, Page 849-878, September 2022., 2022 Modern amphibiotic fishes use various walking techniques but are smaller in length than half a meter, whereas extinct tetrapodomorph fishes of Devonian ranged from 0.5 to 2.5 m. Could they walk out of water, and how did they walk if they could? This study argues that, in recent ichthyofauna, snakehead is most appropriate for modeling walking technique ...

Revision of asterolepidoid antiarch remains from the Ogre Formation (Upper Devonian) of Latvia [PDF]
Estonian Journal of Earth Sciences, 2020 The Frasnian (Upper Devonian) antiarch Walterilepis speciosa was first described in 1933 (as Taeniolepis) on the basis of a single specimen. The newly collected material has allowed the head to be described in a more detail, especially the nuchal and ...

Loss in the making: absence of pelvic fins and presence of paedomorphic pelvic girdles in a Late Devonian antiarch placoderm (jawed stem-gnathostome) [PDF]
Biol Lett, 2018 Within jawed vertebrates, pelvic appendages have been modified or lost repeatedly, including in the most phylogenetically basal, extinct, antiarch placoderms.

Histology of "placoderm" dermal skeletons: Implications for the nature of the ancestral gnathostome [PDF]
J Morphol, 2013 The vertebrate dermal skeleton has long been interpreted to have evolved from a primitive condition exemplified by chondrichthyans. However, chondrichthyans and osteichthyans evolved from an ancestral gnathostome stem-lineage in which the dermal skeleton

The relationships of antiarchs (Devonian placoderm fishes)—evidence supporting placoderm monophyly
Journal of Vertebrate Paleontology, 2008 A recent analysis of the vascularization of the pectoral fin in antiarchs indicated that they resembled jawless osteostracans rather than other jawed vertebrates, thereby challenging the monophyly of the class Placodermi. Examination of the evidence proposed to support this new hypothesis shows misinterpretation of well-established morphology in a ...
