SYSTEMATIC POSITION OF ANTIARCHS (VERTEBRATA, PLACODERMI) FROM THE FAMENNIAN OF TVER REGION, RUSSIA
Известия высших учебных заведений: Геология и разведка, 2017 New materials of the placoderm fish Bothriolepis heckeri Luksеvics from the Famennian of the Bilovo locality (Tver Region) are studied. This species is very similar to Livnolepis zadonica (H.Obrucheva) in the structure of cranial and postcranial armours ...

Hyperossification in the vertebral column of Devonian placoderm fishes (Arthrodira)
, 2020 Skeletal bone enlargement (hyperossification) was thought to only occur in endochondral and dermal bones (e.g., endoskeletons of marine tetrapods and dermal bones of certain jawless vertebrates, placoderms, and teleost fishes).

Placoderms and the evolutionary origin of teeth: a comment on Rücklin & Donoghue (2015) [PDF]
Biology Letters, 2016 The extinct Devonian placoderms (armoured jawed fishes) [[1][1],[2][2]] are central to the question of tooth origins, because some have denticulate ‘toothplates’ within the mouth cavity.

3D microstructural architecture of muscle attachments in extant and fossil vertebrates revealed by synchrotron microtomography. [PDF]
PLoS ONE, 2013 BACKGROUND: Firm attachments binding muscles to skeleton are crucial mechanical components of the vertebrate body. These attachments (entheses) are complex three-dimensional structures, containing distinctive arrangements of cells and fibre systems ...

A diverse group of underappreciated zygnematophytes deserves in-depth exploration
Applied Phycology, 2022 The conjugating green algae (Zygnematophyceae) are the closest relatives of land plants and hence are of great evolutionary interest. Besides the popular placoderm desmids and the filamentous species, there is an underappreciated diversity of unicellular

The Anatomical Record, Volume 309, Issue 10, Page 2574-2635, October 2026.A new musculoskeletal reconstruction and revision of the cranio‐mandibular anatomy of the Devonian arthrodire placoderm Dunkleosteus terrelli from a comparative and functional anatomical perspective. Dunkleosteus is a specialized arthrodire with many specializations for feeding on large vertebrates, and many of its features are part of broader ...

Fish Scales: A Multifunctional Biomaterial from Nature
ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 5, September 2026.Fish scales demonstrate nature's solution to impact protection through overlapping multilayered architecture. This biological design combines mineralized surfaces with collagen networks to achieve both flexibility and fracture resistance. The structural principles inspire advanced protective materials and biomedical implants, where damage tolerance ...
