Abstract An articulated partial skeleton, including a nearly complete skull and left forelimb, of a crocodylomorph reptile from the Upper Triassic Chinle Formation of Ghost Ranch, New Mexico, is referable to Hesperosuchus agilis Colbert, 1952. It contributes much new information on the skeletal structure of this previously poorly known taxon. A large, circular palpebral bone is present in each orbit. The quadratojugal is particularly well preserved and suggests a reinterpretation of this… 
A NEW CROCODYLOMORPH ARCHOSAUR FROM THE UPPER TRIASSIC OF NORTH CAROLINA
Abstract A new taxon of sphenosuchian crocodylomorph, Dromicosuchus grallator, is described on the basis of a well-preserved, largely articulated partial skeleton from Late Triassic strata in the
A SPHENOSUCHIAN (ARCHOSAURIA, CROCODYLOMORPHA) WITH A PARTIAL PELVIS FROM THE UPPER TRIASSIC BULL CANYON FORMATION (NORIAN: REVUELTIAN), EAST- CENTRAL, NEW MEXICO
Sphenosuchians (Archosauria: Crocodylomorpha) are widely distributed in the Late Triassic and Early Jurassic, but are known from few skeletons. Reports of sphenosuchians from Upper Triassic strata of
A New Basal Archosauriform Diapsid from the Lower Triassic of Argentina
TLDR
Koilamasuchus importantly increases the diversity of Archosauriformes during the biotic recovery following the Permo-Triassic mass extinction.
The systematic position of the Late Jurassic alleged dinosaur Macelognathus (Crocodylomorpha: Sphenosuchia)
Macelognathus vagans was described by O.C. Marsh in 1884, based on a mandibular symphysis from the Upper Jurassic Morrison Formation of Wyoming. Often considered a dinosaur but later tentatively
A new short-faced archosauriform from the Upper Triassic Placerias/Downs’ quarry complex, Arizona, USA, expands the morphological diversity of the Triassic archosauriform radiation
TLDR
This specimen appears to be an early example of shortening of the skull, which occurs later in diverse archosaur lineages, including the Late Cretaceous crocodyliform Simosuchus, and further demonstrates that even well-sampled localities can yield new taxa.
A NEW GENUS AND SPECIES OF SPHENODONTIAN FROM THE GHOST RANCH COELOPHYSIS QUARRY (UPPER TRIASSIC: APACHEAN), ROCK POINT FORMATION, NEW MEXICO, USA
Abstract:  We document here a new taxon of sphenodontian, Whitakersaurus bermani gen. et sp. nov., that is also the most complete sphenodontian fossil from the Upper Triassic Chinle Group in the
Redescription of the archosaur Parringtonia gracilis from the Middle Triassic Manda beds of Tanzania, and the antiquity of Erpetosuchidae
Abstract Parringtonia gracilis Huene, 1939 is represented by both cranial and postcranial material collected from the lower Middle Triassic (Anisian) Lifua Member of the Manda beds in southwestern
A DREPANOSAURID PECTORAL GIRDLE FROM THE GHOST RANCH (WHITAKER) COELOPHYSIS QUARRY (CHINLE GROUP, ROCK POINT FORMATION, RHAETIAN), NEW MEXICO
Abstract An isolated but three-dimensionally preserved pectoral girdle from the Rock Point Formation (Rhaetian) of New Mexico represents the youngest known drepanosaurid. The specimen preserves, in
Redescription of the archosaur Parringtonia gracilis from the Middle Triassic Manda beds of Tanzania, and the antiquity of Erpetosuchidae – CORRIGENDUM
TLDR
Parringtonia gracilis and Erpetosuchus granti are added into a comprehensive phylogenetic analysis of early archosaurs and it is found that these taxa are clearly referable to Archosauria but that relationships are poorly resolved at the base of this clade.
A revision ofPoposaurus gracilis (Archosauria: Suchia) based on two new specimens from the Late Triassic of the southwestern U.S.A.
TLDR
The ilia of these new fossils are the first ofPoposaurus to preserve the complete preacetabular blade, which is long and “blade-like” rather than “paddle-shaped” as previously thought.

A NEW SPECIMEN OF AN EARLY CROCODYLOMORPH (CF. SPHENOSUCHUS SP.) FROM THE UPPER TRIASSIC CHINLE FORMATION OF PETRIFIED FOREST NATIONAL PARK, ARIZONA
TLDR
Phylogenetic analysis of the Triassic/Jurassic non-crocodyliform crocodylomorphs (“sphenosuchians”) indicates that the new specimen is most similar to the Early Jurassic genus Sphenosichus.
On the cranial structure of a new protosuchid (Archosauria: Crocodyliformes) from the McCoy Brook Formation (Lower Jurassic) of Nova Scotia, Canada
ABSTRACT Well-preserved skull bones referable to a new protosuchid, Protosuchus micmac, are common in the lower portion of the McCoy Brook Formation (Lower Jurassic: Hettangian) of Nova Scotia,
A Revision of Sphenosuchus acutus Haughton, a Crocodylomorph Reptile from the Elliot Formation (Late Triassic or Early Jurassic) of South Africa
TLDR
It is concluded that the most important steps in crocodylomorph evolution, particularly in the skull, had taken place in sphenosuchians, hence they should be included in the same taxon as protosuchian and more advanced crocodilians, rather than with thecodontians.
Protosuchus, Proterochampsa, and the origin of phytosaurs and crocodiles
TLDR
It is suggested that the skull of Protosuchus includes two pairs of supraorbital bones, and as a consequence the narrow interorbital region indicates a closer relationship to the South African genus Notochampsa than has previously been thought.
Dibothrosuchus elaphros, a crocodylomorph from the Lower Jurassic of China and the phylogeny of the Sphenosuchia
ABSTRACT Much of a skeleton of Dibothrosuchus elaphros from the Lower Lufeng Group (Lower Jurassic) of Yunnan, China permits a detailed review of the anatomy and relationships of sphenosuchian
A revision of the Jurassic reptile Hallopus victor (Marsh), with remarks on the classification of crocodiles
TLDR
It is concluded that a hare-like bounding gallop was the most probable type of fast locomotion in Hallopus .
Geology and taphonomy of the Coelophysis quarry, Upper Triassic Chinle Formation, Ghost Ranch, New Mexico
The Coelophysis dinosaur quarry at Ghost Ranch, near Abiquiu, New Mexico, is unique among Triassic fossil sites for its yield of numerous complete and partial skeletons of a single species of
Postosuchus, a New Thecodontian Reptile from the Triassic of Texas and the Origin of Tyrannosaurs
TLDR
Although Postosuchus exhibits many carnosaurian traits, its ankle joint is of \`crocodile-normal' pattern, which suggests its pseudosuchian affinity, and Tyrannosaurs probably evolved from poposaurids, as indicated by the correlation between skull, pelvis and ankle structure.

TLDR
It is suggested that a trend towards the reduction of the anterior pterygoid muscle took place in aetosaurids, in parallel with a similar trend in ornithischian dinosaurs.
Phylogeny of the Crocodylotarsi, with reference to archosaurian and crurotarsan monophyly
TLDR
The phylogeny of the Crocodylotarsi was re-examined based on study of most relevant fossil material of the early non–crocodyliform members of the clade.
