Phylogenomics Based on Transcriptome Data Provides Evidence for the Internal Phylogenetic Relationships and Potential Terrestrial Evolutionary Genes of Lungfish

open access: yesFrontiers in Marine Science, 2021
The evolutionary relationships of lungfish can provide crucial information on the transition from Sarcopterygii to tetrapods. Phylogenomics is necessary to explore accurate internal phylogenetic relationships among all lungfish species. In the context of

Morphological plasticity in the dentition of the lungfish Gnathorhiza from the Permian of Brazil: A population‐level geometric morphometric analysis

open access: yesThe Anatomical Record, EarlyView.
Abstract Dental plates are pivotal in the lungfish paleontological record, constituting highly mineralized structures resilient to diagenetic processes. This study provides a detailed description and quantitative shape analysis of 95 newly discovered Gnathorhiza sp. dental plates from the Middle–Late Permian Corumbataí Formation, Brazil.

Brain - Endocast Relationship in the Australian Lungfish, Neoceratodus forsteri, Elucidated from Tomographic Data (Sarcopterygii: Dipnoi). [PDF]

open access: yesPLoS ONE, 2015
Although the brains of the three extant lungfish genera have been previously described, the spatial relationship between the brain and the neurocranium has never before been fully described nor quantified.

Fish Scales: A Multifunctional Biomaterial from Nature

open access: yesENERGY &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 ...

The dental plate on bichir pectoral fins: A unique dermal skeletal element bearing individual odontodes with tooth‐like replacement

open access: yesJournal of Anatomy, Volume 249, Issue 1, Page 127-140, July 2026.
Pectoral fins of bichirs encompass the so‐called dental plates – unique dermal skeletal elements with individual odontodes identical to the oral teeth. Abstract The dermal skeleton appeared early in vertebrate evolution in the form of mineralized skin denticles composed of tooth‐like units—odontodes.

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1406-1462, June 2026.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...
