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 …

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 transference of post-dentary jaw elements to the cranium of mammals as auditory
ossicles is one of the central topics in evolutionary biology of vertebrates. Homologies of …

The evolution of the mammalian middle ear is thought to provide an example of
'recapitulation'—the theory that the present embryological development of a species reflects …

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

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 earliest evolution of mammals and origins of mammalian features can be traced to the
mammaliaforms of the Triassic and Jurassic periods that are extinct relatives to living …

MULTITUBERCULATES are an extinct, dentally distinctive group of Mesozoic/early
Cenozoic mammals of uncertain affinities1. We report here the discovery of a …

The phylogeny of Allotheria, including Multituberculata and Haramiyida, remains unsolved
and has generated contentious views on the origin and earliest evolution of mammals. Here …

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 …
