Volume of the crocodilian brain and endocast during ontogeny. [PDF]
PLoS ONE, 2017 Understanding complex situations and planning difficult actions require a brain of appropriate size. Animal encephalisation provides an indirect information about these abilities.

Mandibular musculature constrains brain–endocast disparity between sarcopterygians [PDF]
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.

The cranial endocast of Dipnorhynchus sussmilchi (Sarcopterygii: Dipnoi) and the interrelationships of stem-group lungfishes [PDF]
PeerJ, 2016 The first virtual cranial endocast of a lungfish from the Early Devonian, Dipnorhynchus sussmilchi, is described. Dipnorhynchus, only the fourth Devonian lungfish for which a near complete cranial endocast is known, is a key taxon for clarifying ...

An additional brain endocast of the ictidosaur Riograndia guaibensis (Eucynodontia: Probainognathia): intraspecific variation of endocranial traits [PDF]
Anais da Academia Brasileira de Ciências, 2021 Recently, the morphology and encephalization of the brain endocast of the Triassic non-mammaliaform probainognathian cynodont Riograndia guaibensis were studied. Here, we analyzed the brain endocast of an additional specimen of this species.

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

The olfactory bulb endocast as a proxy for mammalian olfaction [PDF]
Proceedings of the National Academy of Sciences of the United States of AmericaOlfaction is a critical sense for tetrapods, playing a key role in survival and reproduction by aiding in food detection, predator avoidance, and social interactions. Olfactory performance has been experimentally tested in only a few taxa, so comparative analyses rely on anatomical and genomic proxies.

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 ...

The Internal Cranial Anatomy of a Female With Endocrine Disorders From a Mediaeval Population
Frontiers in Endocrinology, 2022 Gigantism and acromegaly have been observed in past populations; however, analyses usually focus on the morphological features of the post-cranial skeleton.

Morphometric analysis of lungfish endocasts elucidates early dipnoan palaeoneurological evolution
eLife, 2022 The lobe-finned fish, lungfish (Dipnoi, Sarcoptergii), have persisted for ~400 million years from the Devonian Period to present day. The evolution of their dermal skull and dentition is relatively well understood, but this is not the case for the ...

Brain Reconstruction Across the Fish-Tetrapod Transition; Insights From Modern Amphibians
Frontiers in Ecology and Evolution, 2021 The fish-tetrapod transition (which incorporates the related fin-limb and water-land transitions) is celebrated as one of the most important junctions in vertebrate evolution.
