The structure and evolution of the mandible, suspensorium, and stapes of mammal‐like reptiles and early mammals are examined in an attempt to determine how, why, and when in phylogeny the precursors of the mammalian tympanic bone, malleus, and incus (postdentary jaw elements and quadrate) came to function in the reception of air‐borne sound. The following conclusions are reached.

Probable diphyletic formation of the mammalian middle ear: Monotremata and Theria
The first steps in the formation of the middle ear of the mammalian type, with the tympanum and three auditory ossicles, have only been passed by higher cynodonts. They have an incipient malleus,… Expand
Eotherapsid hypothesis for the origin of Monotremata
TLDR
Comparative study of the cranial structures of mammals and theromorphs shows that Monotremata evolved from the eotherapsid stem of theROMorphs, while therian mammals are descendants of eutherapsids. Expand
The ear in the theropsida
TLDR
The present paper confirms the suggestion of Allin that the tympanum in the mammal-like reptiles was located in the lower jaw, and shows that this makes sense from the point of view of both evolution and acoustics. Expand
The Evolution of Single- and Multiple-Ossicle Ears in Fishes and Tetrapods
TLDR
The Ostariophysi are the hearing specialists of the ray-finned world and include the gonorynchiforms and a much larger group called the Otophysi, distinguished by having some of the anterior neural arches and supraneurals modified into the Weberian apparatus. Expand
Comment on "Independent Origins of Middle Ear Bones in Monotremes and Therians" (I)
TLDR
The middle ear ossicles of all extant, adult members of crown-group Mammalia are homologous with a series of bones in the lower jaw of nonmammalian amniotes, suggesting that the structurally complex mammalian ear evolved independently. Expand
Non-Mammalian Synapsids: The Beginning of the Mammal Line
TLDR
The anatomy of the middle ear region of the known sequence of fossil stem-group mammals—pelycosaurs, basal therapsids, and several cynodonts—is reviewed in this chapter and the interpretation offers support for the second view. Expand
Coevolution of the Mammalian Middle Ear and Neocortex

Phylogenetic analysis with x-ray computed tomography of fossilized and recent crania implicates differential growth of the neocortex in the evolution and development of the mammalian middle ear. In… Expand
Morphological evolution of the mammalian jaw adductor complex
TLDR
The evolution of the mammalian jaw during the transition from non‐mammalian synapsids to crown mammals is thought to have allowed the evolution of a more‐efficient masticatory system in comparison to the plesiomorphic synapsid condition. Expand
Monotreme middle ear is not primitive for Mammalia
TLDR
Concerns are raised about terminology and identification of the incus presented by Wang et al. and show that their analysis does not support their hypothesis that a middle ear with a monotreme-like incus and malleus and incudomallear articulation was primitive for mammals. Expand
Evolution of the Middle and Inner Ears of Mammaliaforms: The Approach to Mammals
TLDR
The homoplasies of ear structures in early mammalian evolution, although seemingly complex, are consistent with the new understanding of a labile morphogenesis of mammalian ears under a complex developmental genetic network. Expand

The Mammalian Middle Ear
TLDR
Several implications of new work on the anatomy of the middle ear region of mammal-like reptiles were discussed and it was suggested that the primitive reptilian-tympanic cavity was supplemented by a recessus mandibularis related to the region of the notched angular bone. Expand
THE PELYCOSAUR TYMPANUM AND EARLY EVOLUTION OF THE MIDDLE EAR
TLDR
The course of early evolution of the tetrapod middle ear is interpreted in the light of function and support of the tympanum in the pelycosaurs. Expand

It is considered that Eaton’s theory of the transformation of the Rhipidistian hyomandibular to the primitive tetrapod ‘stapes’ or columella is essentially correct. Expand
Dentary-Squamosal Joint and the Origin of Mammals
The dentary-squamosal jaw joint evolved more than once in advanced cynodont therapsids or their descendants, probably as a buttress against the reaction force created at the articulation by the… Expand

TLDR
The functional significance of changes in the middle ear transmission system is discussed, particularly in connection with the origin of the mammalian middle ear, the development of large inner ear potentials and dimensionalChanges in the inner ear. Expand
THE CHORDA TYMPANI AND MIDDLE EAR AS GUIDES TO ORIGIN AND DIVERGENCE OF REPTILES
TLDR
It is demonstrated that the position of the nerve in the pelycosaurs represents a logical intermediate between the condition of fish and amphibians on one hand and all amniotes on the other, and to show that changes of the middle ear from fish to modern amniots can reasonably be documented by known fossil forms.

New Light on the Mammalian Ear Ossicles
TLDR
The structure of the middle ear region of several therapsids is greatly illuminated by this work; but some of his conclusions seem to be open to question, while others can be further supported. Expand
The jaw articulation of the Docodonta and the classification of Mesozoic mammals

  • 1958
TLDR
Comparison with the most advanced of the mammal-like reptiles shows that this groove must have been for the malleus (articular), which in Docodon and in Morganucodon still functioned as part of the jaw articulation, although in both the main part of this hinge would have been formed by the well-developed mammalian condyle on the back end of the dentary.
