Auditory reception in elasmobranchs, teleosts and amphibians may be mediated by various inner-ear sensory epithelia1–3, including the basilar papilla, which seems to be the precursor of the cochlea in mammals. The origin of the basilar papilla remains a major unsolved problem for understanding the evolution of hearing in terrestrial vertebrates4–6. Study of living species indicates that the basilar papilla is a unique feature of tetrapods6,7, but palaeonto-logical data indicate that this… Expand

Evolution of the Amphibian Ear with Implications for Lissamphibian Phylogeny: Insight Gained from the Caecilian Inner Ear
TLDR
Characters of the ear seemingly provide synapomorphies that unite lissamphibians with amphibamid temnospondyls, potentially improving the resolution of concepts about the affinities of frogs, salamanders, and caecilians and clarifying issues of tetrapod ear evolution. Expand
The ear region of Latimeria chalumnae: functional and evolutionary implications.
TLDR
The possibility is considered that the canalis communicans does not possess any auditory function but rather is involved in sensing pressure changes during movements involving the intracranial joint, and earlier hypotheses of a putative tympanic ear are refuted. Expand
The inner ear of gymnophione amphibians and its nerve supply: A comparative study of regressive events in a complex sensory system (Amphibia, Gymnophiona)
TLDR
It is proposed that the presence of a basilar papilla is a synapomorphy of tetrapods and Latimeria, that the translocation of the papilla neglecta is related to the unique course of the amphibian periotic canal, and that regressive changes in the inner ear arerelated to the primitive absence of a tympanic ear.

Evolution of Central Auditory Pathways in Anamniotes
TLDR
It has been recently claimed that the evolution of the papillar endorgans, at least of anamniotes, predates the emergence of vertebrates onto land (Fritzsch 1987, Chapter 18), a view that requires us to reconsider the selective pressures that influenced the appearance of acoustic receptors. Expand
Remarks on the inner ear of elasmobranchs and its interpretation from skeletal labyrinth morphology
  • J. Maisey

The structure and function of the craniate inner ear is reviewed, with 33 apomorphic characters of the membranous labyrinth and associated structures identified in craniates, gnathostomes, and… Expand
The inner ear of the lungfish Protopterus
TLDR
The sensory end organs of the inner ear of the lungfish, Protopterus, were examined using scanning and transmission electron microscopy and the presence of a macula neglecta was confirmed near the posterior canal as a tiny single patch of a few dozen hair cells with all the cell orientations directed caudally. Expand
Sarcopterygians: From Lobe-Finned Fishes to the Tetrapod Stem Group
TLDR
The sarcopterygians or lobe-finned fishes is the group that gave rise to tetrapod-like forms from the Late Devonian, and the braincases of dipnoans (lungfishes) were the most highly modified with consolidated fore and aft portions and reduction or loss of the hyomandibula. Expand
Paedomorphosis and simplification in the nervous system of salamanders.
TLDR
It is suggested that, although increasing genome size and paedomorphosis tend to compromise the function of the salamander brain, compensating mechanisms have evolved that may restore or even enhance brain function. Expand
Close tetrapod relationships of the coelacanth Latimeria indicated by haemoglobin sequences
TLDR
The primary structure of Ii haemoglobin indicates that the coelacanth is the closest living relative of tetrapods. Expand
The Coelacanth Latimeria chalumnae
TLDR
The most important distinguishing feature of these fishes is the division of the neurocranium into two parts, an anterior, ethmo-sphenoid portion and a posterior, otico-occipital portion with an intracranial joint between them. Expand
