In non-mammalian synapsids and early mammals, evolutionary transformations in the
feeding and hearing apparatuses are posited to have been prerequisites for the radiation of …

The evolution of the various hearing adaptations is connected to major structural changes in
nearly all groups of vertebrates. Besides hearing, the detection of acceleration and …

Stem mammaliaforms are forerunners to modern mammals, and they achieved considerable
ecomorphological diversity in their own right. Recent discoveries suggest that …

Haramiyida was a successful clade of mammaliaforms, spanning the Late Triassic period to
at least the Late Jurassic period, but their fossils are scant outside Eurasia and Cretaceous …

Gliding is a distinctive locomotion type that has been identified in only three mammal
species from the Mesozoic era. Here we describe another Jurassic glider that belongs to the …

The dual jaw joint of Morganucodon, consists of the dentary–squamosal joint laterally and
the articular–quadrate one medially. The articular–quadrate joint and its associated post …

The estimation of the timing of major divergences in early mammal evolution is challenging
owing to conflicting interpretations of key fossil taxa. One contentious group is Haramiyida …

Among extant vertebrates, mammals are distinguished by having a chain of three auditory
ossicles (the malleus, incus and stapes) that transduce sound waves and promote an …

Multiple mammalian lineages independently evolved a definitive mammalian middle ear
(DMME) through breakdown of Meckel's cartilage (MC). However, the cellular and molecular …

The reflected lamina of the angular has long been portrayed as a key component in
understanding the evolution of the mammalian mandible and middle ear, yet the function of …
