A new method for reconstructing brain morphology: applying the brain-neurocranial spatial relationship in an extant lungfish to a fossil endocast [PDF]
Royal Society Open Science, 2016 Lungfish first appeared in the geological record over 410 million years ago and are the closest living group of fish to the tetrapods. Palaeoneurological investigations into the group show that unlike numerous other fishes—but more similar to those in ...

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates. [PDF]
Biol Rev Camb Philos SocABSTRACT 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 ...

Histology of juvenile skin of Lepidosiren paradoxa Fitzinger, 1837 (Sarcopterygii, Dipnoi) [PDF]
Anais da Academia Brasileira de Ciências, 2019 : The skin of three juvenile Lepidosiren paradoxa specimens was examined. The epidermis was composed of a polystratified epithelium resting on a basement membrane, including mucus-secreting cells, and a cuticle of mucopolysaccharides on the surface.

The missing anatomy of the living coelacanth, Latimeria chalumnae (Smith, 1939) [PDF]
Vertebrate Zoology, 2022 Anatomical features that have not been previously described in Latimeria were sought in histological section series, tissue-stained microCT scans, MRI scans, and synchrotron scan series.

Visual pigments in a living fossil, the Australian lungfish
BMC Evolutionary Biology, 2007 Background One of the greatest challenges facing the early land vertebrates was the need to effectively interpret a terrestrial environment. Interpretation was based on ocular adaptations evolved for an aquatic environment millions of years earlier.

A Morphological and Histological Investigation of Imperfect Lungfish Fin Regeneration
Frontiers in Ecology and Evolution, 2021 Regeneration, the replacement of body parts in a living animal, has excited scientists for centuries and our knowledge of vertebrate appendage regeneration has increased significantly over the past decades.

Mandibular musculature constrains brain–endocast disparity between sarcopterygians
Royal Society Open Science, 2020 The transition from water to land by the earliest tetrapods in the Devonian Period is seen as one of the greatest steps in evolution. However, little is understood concerning changes in brain morphology over this transition.
