Olfactory Projections in the Lepidosirenid Lungfishes [PDF]
Brain, Behavior and Evolution, 2011 Olfactory nerve and olfactory bulb projections in lepidosirenid lungfishes were experimentally determined with neural tracers. Unilateral injections of DiI into the olfactory nerve labeled the accessory and main olfactory bulbs as well as fibers of the anterior root of the terminal nerve, which terminates extensively in cell groups of the medial ...

Type 1 vomeronasal receptor expression in juvenile and adult lungfish olfactory organ
Zoological Letters, 2023 Lungfish are the most closely related fish to tetrapods. The olfactory organ of lungfish contains lamellae and abundant recesses at the base of lamellae.

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 ...

“Living fossils” and the mosaic evolution of characters
Frontiers in Ecology and Evolution, 2023 The modern discussion of living fossils turns mostly on the persistence of archaic, or ancestral, traits in extant organisms. Prime examples mentioned by Darwin already—who also coined the term “living fossil”—include the platypus and the extant ...

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.

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.

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.

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.
