Mammaliamorpha comprises the last common ancestor of Tritylodontidae and Mammalia plus all its descendants1. Tritylodontids are nonmammaliaform herbivorous cynodonts that originated in the Late Triassic epoch, diversified in the Jurassic period2-5 and survived into the Early Cretaceous epoch6,7. Eutriconodontans have generally been considered to be an extinct mammalian group, although different views exist8. Here we report a newly discovered tritylodontid and eutriconodontan from the Early… Expand

First record of a basal mammaliamorph from the early Late Triassic Ischigualasto Formation of Argentina
TLDR
A new probainognathian cynodont from the early Late Triassic Ischigualasto Formation of Argentina is described, which consists of a well-preserved isolated skull that preserves apomorphic features of the orbit and braincase and finds weak support for Pseudotherium as the sister taxon of Tritylodontidae.

Skeleton of a Cretaceous mammal from Madagascar reflects long-term insularity
TLDR
The skeleton of Adalatherium hui, a newly discovered gondwanatherian mammal from Madagascar dated to near the end of the Cretaceous period, shows features consistent with a long evolutionary trajectory of isolation in an insular environment. Expand
Mesozoic mammals of China: implications for phylogeny and early evolution of mammals
TLDR
The superb specimens from nearly all major groups of Mesozoic mammals in China provided a great amount of information that contributed to understanding on some major issues in phylogeny and the early evolution of mammals, such as divergences of mammals and the evolution of the mammalian middle ear.

The Phylogenetic Relationships of Eucynodontia (Amniota: Synapsida)
TLDR
A cladistic analysis, based on 145 characters and 31 species, and intergrating most prior works, confirmed the monophyly of Eucynodontia, although the results slightly differ from those of previous analyses with respect to the composition of both Cynognathia and ProbainognathIA. 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
The Postcranial Skeleton of Yanoconodon allini from the Early Cretaceous of Hebei, China, and Its Implications for Locomotor Adaptation in Eutriconodontan Mammals
TLDR
These postcranial skeletal features imply that Yanoconodon had a sprawling posture and was a generalized terrestrial mammal, whereas its capability of swimming was inferred from multivariate ecomorphological analysis using extant small-bodied mammals as analogs. Expand
Evolution and identity of synapsid carpal bones
TLDR
The observations provided here provide an updated revision of synapsid carpal homologies, mainly on the basis of position and anatomical contacts and also taking into account the results of embryological studies. Expand
A Tritylodontid Synapsid from the Middle Jurassic of Siberia and the Taxonomy of Derived Tritylodontids
TLDR
Discovery of Stereognathus in the Itat Formation underlines the similarity of the vertebrate assemblage from this stratigraphic unit to the British Bathonian vertebrates and the Early Cretaceous vertebrate fauna from the Ilek Formation in Siberia. Expand
A new eutriconodont mammal and evolutionary development in early mammals
TLDR
A Mesozoic eutriconodont nested within crown mammals that clearly illustrates this transition: the middle ear bones are connected to the mandible via an ossified Meckel’s cartilage, adding to the evidence of homoplasy of vertebral characters in the thoraco-lumbar transition and unfused lumbar ribs among early mammals.

A new eutriconodont mammal from the early Cretaceous Jehol Biota of Liaoning, China
A new genus and species of eutriconodont mammal, Chaoyangodens lii gen. et sp. nov., from the Dawangzhangzi bed of Yixian Formation, Lingyuan, Liaoning, is reported. The new species has a toothExpand
