AMNIOTE PHYLOGENY AND THE IMPORTANCE OF FOSSILS
TLDR
The importance of the critical fossils seems to reside in their relative primitive‐ness, and the simplest explanation for their more conservative nature is that they have had less time to evolve. Expand
Definition, diagnosis, and origin of Mammalia
TLDR
Triassic and Early Jurassic taxa commonly referred to as mammals, including Morganucodontidae, Kuehneotheriidae, and Haramiyidae, were found to lie outside of Mammalia. Expand
Fossil Evidence on Origin of the Mammalian Brain
Evidence from two early fossils suggests that brain enlargement and specialization proceeded in three pulses. Many hypotheses have been postulated regarding the early evolution of the mammalianExpand
A new species of the theropod dinosaur Syntarsus from the Early Jurassic Kayenta Formation of Arizona
TLDR
The discovery of Syntarsus in North America adds significantly to the increasingly detailed resemblance of African and North American Early Jurassic terrestrial vertebrate faunas. Expand
The avian nature of the brain and inner ear of Archaeopteryx
TLDR
It is concluded that Archaeopteryx had acquired the derived neurological and structural adaptations necessary for flight and had also developed enhanced somatosensory integration with these special senses demanded by a lifestyle involving flying ability. Expand
Osteology and Relationships of Byronosaurus jaffei (Theropoda: Troodontidae)
TLDR
Several interesting characters of Byronosaurus jaffei have implications both for theropod relationships and for understanding patterns of variation within coelurosaurian theropods. Expand
Neuroanatomy of flying reptiles and implications for flight, posture and behaviour
TLDR
The brain and vestibular apparatus in two pterosaurs are compared based on high-resolution computed tomographic (CT) scans from which they were constructed digital endocasts to shed light on adaptation to an aerial lifestyle. Expand
The oldest platypus and its bearing on divergence timing of the platypus and echidna clades
TLDR
Evidence from high-resolution x-ray computed tomography indicating that Teinolophos, an Early Cretaceous fossil from Australia's Flat Rocks locality, lies within the crown clade Monotremata, as a basal platypus is described, suggesting that rate heterogeneities may have affected mammalian evolution in such a way as to defeat strict molecular clock models and to challenge even relaxed molecular Clock models when applied to mammalian history at a deep temporal scale.

The Campanian Terlingua local fauna, with a summary of other vertebrates from the Aguja Formation, Trans-Pecos Texas
ABSTRACT The Terlingua local fauna is a rich assemblage of predominantly terrestrial micro vertebrates from the Upper Cretaceous Aguja Formation of Trans-Pecos Texas. Marine invertebrates (whichExpand
Hindlimb Osteology and Distribution of Basal Dinosauromorphs from the Late Triassic of North America
ABSTRACT The recent discovery of early dinosauromorphs from North America demonstrates that they were contemporaries with dinosaurs and other basal archosaurs during a substantial portion of theExpand
