Stem mammaliaforms are Mesozoic forerunners to mammals, and they offer critical evidence for the anatomical evolution and ecological diversification during the earliest mammalian history. Two new eleutherodonts from the Late Jurassic period have skin membranes and skeletal features that are adapted for gliding. Characteristics of their digits provide evidence of roosting behaviour, as in dermopterans and bats, and their feet have a calcaneal calcar to support the uropagatium as in bats. The new… 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
New evidence for mammaliaform ear evolution and feeding adaptation in a Jurassic ecosystem
TLDR
A new Jurassic eleutherodontid mammaliaform with an unusual mosaic of highly specialized characteristics is reported, and the results of phylogenetic analyses support the hypothesis that haramiyidans are stem mammaliaforms. Expand
Late-surviving stem mammal links the lowermost Cretaceous of North America and Gondwana
TLDR
It is suggested that hahnodontid mammaliaforms had a much wider, possibly Pangaean distribution during the Jurassic–Cretaceous transition, and an exceptionally preserved skull of Cifelliodon wahkarmoosuch sheds light on the evolution of the ancestral mammalian brain. Expand
The earliest-known mammaliaform fossil from Greenland sheds light on origin of mammals
TLDR
The earliest-known mandibular fossil of a mammaliaform with double molariform roots and a crown with two rows of cusps from the Late Triassic of Greenland is described and indicates that teeth with two roots can better withstand stronger mechanical stresses like those resulting from tooth occlusion, than teeth with a single root. Expand
Antiquity of forelimb ecomorphological diversity in the mammalian stem lineage (Synapsida)
TLDR
This evolutionary pattern confirms that nonmammaliaform therapsid forelimbs underwent ecomorphological diversification throughout the Permian, with functional elaboration initially being more strongly expressed in the proximal end of the humerus than the distal end. Expand
Postcranial Skeleton of Henkelotherium guimarotae (Cladotheria, Mammalia) and Locomotor Adaptation
TLDR
The previously proposed hypothesis of an arboreal lifestyle for Henkelotherium is corroborated by a number of skeletal features such as large humeral entepicondyles, prominent digital flexor tubercles, elongated and slender tail vertebrae, as well as a high pedal phalangeal index of 153%. Expand
Patterns of mammalian jaw ecomorphological disparity during the Mesozoic/Cenozoic transition
TLDR
Total mammal disparity exceeded its Mesozoic maximum for the first time during the Eocene, when therian mammals began exploring previously unoccupied regions of function space, and probably reflects the duration of evolutionary recovery after the K/Pg mass extinction event. Expand
Introduction to Adalatherium hui (Gondwanatheria, Mammalia) from the Late Cretaceous of Madagascar
ABSTRACT Adalatherium hui is a latest Cretaceous (Maastrichtian) gondwanatherian mammal based on only a single specimen, a virtually complete, articulated, and well-preserved skull and postcranialExpand
Dinosaurs, But Not Only: Vertebrate Evolution in the Mesozoic
If we imagine walking through Mesozoic lands, we would be able to observe vertebrates with peculiar combinations of morphological traits, some of which would seem to be intermediary to animals seenExpand
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 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
New evidence for mammaliaform ear evolution and feeding adaptation in a Jurassic ecosystem
TLDR
A new Jurassic eleutherodontid mammaliaform with an unusual mosaic of highly specialized characteristics is reported, and the results of phylogenetic analyses support the hypothesis that haramiyidans are stem mammaliaforms. 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
A Swimming Mammaliaform from the Middle Jurassic and Ecomorphological Diversification of Early Mammals
TLDR
This fossil demonstrates that some mammaliaforms, or proximal relatives to modern mammals, developed diverse locomotory and feeding adaptations and were ecomorphologically different from the majority of generalized small terrestrial Mesozoic mammalian insectivores. 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
Mandibular and dental characteristics of Late Triassic mammaliaform Haramiyavia and their ramifications for basal mammal evolution
TLDR
Tests of competing phylogenetic hypotheses with new data show that Late Triassic haramiyids are a separate clade from multituberculate mammals and are excluded from the Mammalia, suggesting that dietary diversification is a major factor in the earliest mammaliaform evolution. Expand
Haramiyids and Triassic mammalian evolution
TLDR
The discovery of haramiyid dentaries, a maxilla and other skeletal remains in the Upper Triassic of East Greenland revealsHaramiyids as highly specialized mammals with a novel pattern of puncture-crushing occlusion that differs dramatically from the grinding or shearing mechanisms of other Early Mesozoic mammals. Expand
Mammal disparity decreases during the Cretaceous angiosperm radiation
TLDR
It is concluded that during the mid-Cretaceous, the period of rapid angiosperm radiation, mammals experienced both a decrease in morphological disparity and a functional shift in dietary morphology that were probably related to changing ecosystems. Expand
A new arboreal haramiyid shows the diversity of crown mammals in the Jurassic period.
TLDR
A new haramiyid from the Jurassic period of China is reported, which is, to the authors' knowledge, the largest reported so far and shows again that, regardless of various phylogenetic scenarios, a complex pattern of evolution involving many convergences and/or reversals existed in Mesozoic mammals. Expand
Three new Jurassic euharamiyidan species reinforce early divergence of mammals
TLDR
The phylogeny suggests that allotherian mammals evolved from a Late Triassic Haramiyavia-like ancestor and diversified into euharamiyidans and multituberculates with a cosmopolitan distribution, implying homologous acquisition of many craniodental and postcranial features in the two groups. Expand
