Ornithischia is one of the two major groups of dinosaurs, with heterodontosauridae as one of its major clades. Heterodontosauridae is characterized by small, gracile bodies and a problematic phylogenetic position. Recent phylogenetic work indicates that it represents the most basal group of all well-known ornithischians. Previous heterodontosaurid records are mainly from the Early Jurassic period (205–190 million years ago) of Africa. Here we report a new heterodontosaurid, Tianyulong…

A Middle Jurassic heterodontosaurid dinosaur from Patagonia and the evolution of heterodontosaurids
TLDR
A new ornithischian dinosaur from the Middle Jurassic Cañadón Asfalto Formation in central Patagonia, Argentina is reported, and derived features of its anatomy indicate that Manidens belongs to Heterodontosauridae, as the sister taxon of HeterODontosaurus and other South African heterodontsaurids.
TEMPORARY REMOVAL: A maned theropod dinosaur from Gondwana with elaborate integumentary structures
Exceptionally preserved juvenile megalosauroid theropod dinosaur with filamentous integument from the Late Jurassic of Germany
TLDR
Sciurumimus albersdoerferi represents the phylogenetically most basal theropod that preserves direct evidence for feathers and helps close the gap between feathers reported in coelurosaurian theropods and filaments in ornithischians, further supporting the homology of these structures.
The postcranial osteology and phylogenetic position of the small ornithischian dinosaur Changchunsaurus parvus from the Quantou Formation (Cretaceous: Aptian–Cenomanian) of Jilin Province, north‐eastern China
TLDR
A phylogenetic analysis finds relationships amongst basal ornithopods to be extremely poorly resolved, but supports a sister-group relationship between Changchunsaurus and Jeholosaurus shangyuanensis and suggests that an endemic clade of small-bodied bipedal ornithipods existed in north-east China during the Early to ‘middle’ Cretaceous.
A new microraptorine theropod from the Jehol Biota and growth in early dromaeosaurids
TLDR
Comparison of histology in the new taxon and Sinornithosaurus indicates that macroscopic signs of maturity developed after the first year, but before cessation of growth, demonstrating that nonhistological indicators of adulthood may be misleading when applied to dromaeosaurids.
Postcranial anatomy of Lesothosaurus diagnosticus (Dinosauria: Ornithischia) from the Lower Jurassic of southern Africa: implications for basal ornithischian taxonomy and systematics
TLDR
This study has found that the material of L. diagnosticus and S. dangershoeki almost certainly represents the same taxon and that the apparent differences between these genera is probably a product of ontogentic (rather than taxonomic) differences.
New heterodontosaurid specimens from the Lower Jurassic of southern Africa and the early ornithischian dinosaur radiation
ABSTRACT Heterodontosaurids are poorly understood early ornithischian dinosaurs with extensive geographic and stratigraphic ranges. The group is best known from the Lower Jurassic upper ‘Stormberg…
Integumentary Structures in Kulindadromeus zabaikalicus, a Basal Neornithischian Dinosaur from the Jurassic of Siberia
TLDR
Kulindadromeus zabaikalicus, a basal neornithischian dinosaur from the Jurassic of Siberia, preserves diverse integumentary structures, including monofilaments, more complex protofeather structures and scales on its tail and distal parts of its limbs, suggesting that integumental features were diversified even in ornithischians.
Phylogenetic reassessment of Pisanosaurus mertii Casamiquela, 1967, a basal dinosauriform from the Late Triassic of Argentina
TLDR
The present analysis indicates that Pisanosaurus should be removed from the base of the Ornithischia and should no longer be considered the oldest representative of this dinosaurian clade.
The Late Triassic dinosauromorph Sacisaurus agudoensis (Caturrita Formation; Rio Grande do Sul, Brazil): anatomy and affinities
Abstract Silesauridae is an exclusively Triassic group of dinosauromorphs, knowledge on the diversity of which has increased dramatically in the last few years. Silesaurid relationships are still…

A basal ceratopsian with transitional features from the Late Jurassic of northwestern China
TLDR
Character distributions along the marginocephalian lineage reveal that, compared to the bipedal Pachycephalosauria, the dominantly quadrupedal ceratopsians lost many marginocesphalian features and evolved their own characters early in their evolution.
A bizarre Jurassic maniraptoran from China with elongate ribbon-like feathers
TLDR
This finding shows that a member of the avialan lineage experimented with integumentary ornamentation as early as the Middle to Late Jurassic, and provides further evidence relating to this aspect of the transition from non-avian theropods to birds.
A Juvenile Skull of the Primitive Ornithischian Dinosaur Heterodontosaurus Tucki from the 'Stormberg' of Southern Africa
TLDR
A new partial skull of a juvenile Heterodontosaurus tucki from the 'Stormberg' of South Africa is described, providing new information on the cranial anatomy of this taxon as well as insights into cranial ontogeny, sexual dimorphism and tooth replacement in heterodontosaurids.
Anatomy of Sinosauropteryx prima from Liaoning, northeastern China
A spectacular pair of Sinosauropteryx skeletons from Jurassic–Cretaceous strata of Liaoning in northeastern China attracted worldwide notoriety in 1996 as the first dinosaurs covered with…
A New Enantiornitine Bird with Four Long Rectrices from the Early Cretaceous of Northern Hebei, China
TLDR
This is the first record of Mesozoic birds in having four long rectrices, which may represent morphologically a secondary sexual character, an intermediate stage from elongated scale to branched feather, and possess functional advantage in supplementing the lifting surface to compensate the unskilled flight.
The phylogeny of the ornithischian dinosaurs
TLDR
Surprisingly, Heterodontosauridae is placed as the most basal group of all well‐known ornithischians, phylogenetically distant from a stem‐defined Ornithopoda, creating a topology that is more congruent with the known Ornithischian stratigraphical record.
A new Chinese specimen indicates that ‘protofeathers’ in the Early Cretaceous theropod dinosaur Sinosauropteryx are degraded collagen fibres
TLDR
A new specimen of Sinosauropteryx is reported which shows that the integumental structures proposed as protofeathers are the remains of structural fibres that provide toughness.
An exceptionally preserved Lower Cretaceous ecosystem
TLDR
Findings include feathered theropod dinosaurs and early birds, which provide additional, indisputable support for the dinosaurian ancestry of birds, and much new evidence on the evolution of feathers and flight.
