A docodontan mammaliaform from the Middle Jurassic of China possesses swimming and burrowing skeletal adaptations and some dental features for aquatic feeding. It is the most primitive taxon in the mammalian lineage known to have fur and has a broad, flattened, partly scaly tail analogous to that of modern beavers. We infer that docodontans were semiaquatic, convergent to the modern platypus and many Cenozoic placentals. This fossil demonstrates that some mammaliaforms, or proximal relatives to… Expand
An arboreal docodont from the Jurassic and mammaliaform ecological diversification
TLDR
A new docodontan mammaliaform from the Middle Jurassic of China has skeletal features for climbing and dental characters indicative of an omnivorous diet that included plant sap, revealing a greater ecological diversity in an early mammaliaforms clade at a more fundamental taxonomic level not only between major clades as previously thought. Expand
A Jurassic mammaliaform and the earliest mammalian evolutionary adaptations
TLDR
A new fossil from the Middle Jurassic that has a mandibular middle ear, a gradational transition of thoracolumbar vertebrae and primitive ankle features, but highly derived molars with a high crown and multiple roots that are partially fused is described. Expand
Evolutionary development in basal mammaliaforms as revealed by a docodontan
TLDR
It is argued that these morphogenetic mechanisms ofmodern mammals were operating before the rise of modern mammals, driving the morphological disparity in the earliest mammaliaform diversification. Expand
Mammals that coexisted with dinosaurs
Seven fossil sites of Mesozoic mammals have been discovered in Russia: four in Western Siberia (one Middle Jurassic and three Early Cretaceous), one in European Russia (Middle Jurassic), one inExpand
Modern Data on the Origin and Early Radiation of Mammals
TLDR
New paleontological and embryological data on the morphogenesis of the auditory ossicles demonstrate parallel developments of the definitive mammal middle ear in the placentals, marsupials, and monotremes, as well as the independent origins of a number of early groups. Expand
A Mesozoic gliding mammal from northeastern China
TLDR
A new Mesozoic mammal from Inner Mongolia, China, is reported that represents a previously unknown group characterized by a highly specialized insectivorous dentition and a sizable patagium (flying membrane) for gliding flight. Expand
New gliding mammaliaforms from the Jurassic
TLDR
Two new eleutherodonts from the Late Jurassic period have skin membranes and skeletal features that are adapted for gliding, and show an evolutionary experimentation similar to the iterative evolutions of gliders within arboreal groups of marsupial and placental mammals. Expand
New Jurassic mammaliaform sheds light on early evolution of mammal-like hyoid bones
TLDR
A Jurassic fossil shows that early premammalian ancestors possessed hyoids similar to those seen in mammals today, and a new Jurassic docodontan mammaliaform found in China that is preserved with the hyoid bones is reported. Expand
Analysis of Molar Structure and Phylogeny of Docodont Genera
TLDR
A phylogenetic analysis of 31 dental characters of docodonts (12 genera), plus six outgroups, supports a prior hypothesis that this group dispersed to Gondwana during the Middle Jurassic and hypothesizes that docodons and Late Triassic Tikitherium are sister taxa, and that the Tikitheringium-docodont clade, in turn, is related to the mammaliaforms Woutersia and Delsatia.

An Early Cretaceous Tribosphenic Mammal and Metatherian Evolution
TLDR
New data from this fossil support the view that Asia was likely the center for the diversification of the earliest metatherians and eutherians during the Early Cretaceous. Expand
A New Mammaliaform from the Early Jurassic and Evolution of Mammalian Characteristics
TLDR
A fossil from the Early Jurassic represents a new lineage of mammaliaforms, the extinct groups more closely related to the living mammals than to nonmammaliaform cynodonts, and shows that several key mammalian evolutionary innovations in the ear region, the temporomandibular joint, and the brain vault evolved incrementally through mammaliaform evolution and long before the differentiation of the living mammal groups.

The earliest known eutherian mammal
TLDR
The skeleton of a eutherian (placental) mammal found in northeastern China has limb and foot features that are known only from scansorial and arboreal extant mammals, in contrast to the terrestrial or cursorial features of other Cretaceous eutherians. Expand
Dual origin of tribosphenic mammals
TLDR
Phylogenetic and morphometric analyses including these newly discovered taxa suggest a different interpretation: that mammals with tribosphenic molars are not monophyletic. Expand
Dental Morphology of the Jurassic Holotherian Mammal Amphitherium, with a Discussion of the Evolution of Mammalian Post‐Canine Dental Formulae
TLDR
It is concluded that Amphitherium probably had reached the grade of modern therians in the division between diphyodont premolars and monophyodont molars. Expand
A new maniraptoran dinosaur from China with long feathers on the metatarsus
TLDR
A new eumaniraptoran theropod from China, with avian affinities, is reported, which also has long pennaceous feathers on its feet, suggesting that such morphology might represent a primitive adaptation close to the theropOD–bird transition. Expand
