Palaeomagnetism of red beds of the Late Devonian Worange Point Formation, SE Australia [PDF]

open access: yes, 1991
Gently folded strata of the Late Devonian Merrimbula Group along the south coast of New South Wales are similar to numerous deposits of Late Devonian to Early Carboniferous, subaerial to shallow marine, quartzose sandstone that are known as the Lambie ...

Unique diversity of acanthothoracid placoderms (basal jawed vertebrates) in the Early Devonian of the Prague Basin, Czech Republic: A new look at Radotina and Holopetalichthys.

open access: yesPLoS ONE, 2017
The taxonomy of Early Devonian placoderm material from the Lochkovian and Pragian of the Prague basin, previously attributed to the genera Radotina and Holopetalichthys, is revised.

Evidence for Placoderms from the Mid-Palaeozoic Sandon Beds of North-western New South Wales, Australia [PDF]

open access: yes, 2023
Armoured jawed fishes known as placoderms are a well-documented group with a fossil record spanning the Silurian to end-Devonian. They have a global distribution and a marked diversity within Devonian deposits of Australia. Despite their notable Gondwanan

Early Frasnian acanthodians from central Iran [PDF]

open access: yes, 2006
Two vertebrate-bearing horizons in the basal Frasnian carbonate of the Chahriseh section, northeast of Esfahan, yielded microremains of thelodonts, placoderms, acanthodians, actinopterygians, chondrichthyans, and sarcopterygians, considerably expanding ...

Morphological Disparity and Evolutionary Radiation of Early Actinopterygians Through the Devonian–Carboniferous Crisis

open access: yesDiversity
“Placoderm” and sarcopterygian fishes dominated Devonian waters. Following the end-Devonian crisis, actinopterygians rapidly became major contributors to vertebrate diversity.

Placoderms (Armored Fish): Dominant Vertebrates of the Devonian Period

open access: yesAnnual Review of Earth and Planetary Sciences, 2010
Placoderms, the most diverse group of Devonian fishes, were globally distributed in all habitable freshwater and marine environments, like teleost fishes in the modern fauna. Their known evolutionary history (Early Silurian–Late Devonian) spanned at least 70 million years.
