ABSTRACT The paraphyletic genus ‘Paleorhinus’ is understood currently as a cosmopolitan phytosaur taxon from the Late Triassic. There is no consensus regarding the number of species of ‘Paleorhinus,’ with multiple species and genera synonymised into a single genus or even a single species at various points in its published history. The taxonomy is confounded by historical descriptions without the benefit of comparisons to more recently collected specimens, emphasis on plesiomorphic cranial… 
Redescription of the phytosaurs Paleorhinus (‘Francosuchus’) angustifrons and Ebrachosuchus neukami from Germany, with implications for Late Triassic biochronology
It is provided the first autapomorphy-based support for a monophyletic but restricted Paleorhinus (supported by a nodal row on the jugal, and low paired ridges on the squamosal) and confirmed that previous broader conceptions of Paleorlinus are likely to be paraphyletic.
A new phylogenetic analysis of Phytosauria (Archosauria: Pseudosuchia) with the application of continuous and geometric morphometric character coding
This work presents the most taxonomically comprehensive cladistic dataset of phytosaurs to date, based on extensive first-hand study, identification of novel characters and synthesis of previous matrices, which results in an almost twofold increase in phylogenetic information scored per taxon over previous analyses.
Redescription of Calyptosuchus (Stagonolepis) wellesi (Archosauria: Pseudosuchia: Aetosauria) from the Late Triassic of the Southwestern United States with a discussion of genera in vertebrate paleontology

Mapping of aetosaurian elements from the Placerias Quarry allows for the recognition of associated material providing support for referrals of non-osteoderm material and provides a proposed taxonomic relationship that cannot be unambiguously supported, even by phylogenetic analyses.
Cranial morphology of a new phytosaur (Diapsida, Archosauria) from the Upper Triassic of India: implications for phytosaur phylogeny and biostratigraphy
Detailed description and phylogenetic assessment of a phytosaur skull collected from the Tiki Formation of the Rewa Gondwana Basin of India and earlier diagnosed as Parasuchus hislopi, show that it
A Short-Snouted, Middle Triassic Phytosaur and its Implications for the Morphological Evolution and Biogeography of Phytosauria
The exquisitely preserved, nearly complete skeleton of Diandongosuchus fuyuanensis from the Middle Triassic of China is recognized as the oldest and basalmost phytosaur, indicating that the characteristic elongated rostrum of phytosaurs appeared subsequent to cranial and postcranial modifications associated with enhanced prey capture, predating that general trend of morphological evolution observed within Crocodyliformes.
Relationships of the Indian phytosaur Parasuchus hislopi Lydekker, 1885
The neotype skull of the Indian phytosaur Parasuchus hislopi Lydekker, 1885 is re‐evaluated and compared with the type material of other basal phytosaurs, finding it in a well‐supported clade with P. bransoni and P. angustifrons.
New trilophosaurid species demonstrates a decline in allokotosaur diversity across the Adamanian-Revueltian boundary in the Late Triassic of western North America
Abstract Allokotosauria, including Trilophosauridae and Azendohsauridae, is an extinct archosauromorph group that reached a near-Pangean distribution in the Middle Triassic to Late Triassic and
The Early Fossil Record of Dinosaurs in North America: A New Neotheropod from the Base of the Upper Triassic Dockum Group of Texas
Using the most comprehensive analysis of early theropod relationships currently available, it is determined that the new specimen represents one of the oldest neotheropods and was present at or just after the onset of both the Chinle Formation and Dockum Group deposits.
First Occurrence of Doswellia cf. D. Kaltenbachi (Archosauriformes) from the Late Triassic (Middle Norian) Chinle Formation of Arizona and Its Implications on Proposed Biostratigraphic Correlations across North America during the Late Triassic
ABSTRACT Doswellia kaltenbachi is a long-snouted non-archosaur archosauriform known from the Late Triassic of the United States (Virginia and Texas). New material from the Chinle Formation of Arizona
Cranial evolution of the Late Triassic phytosaurs (Diapsida, Archosauria): preliminary observations from landmark-based morphometric analysis
ABSTRACT Landmark-based Principal Component Analysis was performed on multiple phytosaur and crocodilian skulls. Multiple landmark points were selected defining suture points of bone tissues and


A new taxon of phytosaur (Archosauria: Pseudosuchia) from the Late Triassic (Norian) Sonsela Member (Chinle Formation) in Arizona, and a critical reevaluation of Leptosuchus Case, 1922
Support for the previously proposed, but undemonstrated, sister taxon relationship between Angistorhinus and Rutiodon is not supported, Paleorhinus is recovered as paraphyletic, and a subset of taxa traditionally included within Leptosuchus are found to be more closely related to Pseudopalatinae, rendering LeptOSuchus paraphYletic.
The holotype of P. jablonskiae is of biochronological significance because it is the stratigraphically lowest occurrence of Pseudopalatus within the Chinle Formation of Petrified Forest National Park, and provides strong evidence for the overlap of the Adamanian and Revueltian land-vertebrate faunachrons.
The higher-level phylogeny of Archosauria (Tetrapoda: Diapsida)
This analysis produces a well-resolved phylogeny, which recovers mostly traditional relationships within Avemetatarsalia, places Phytosauria as a basal crurotarsan clade, finds a close relationship between Aetosaurian and Crocodylomorpha, and recovers a monophyletic Rauisuchia comprised of two major subclades.
The Late Triassic Phytosaur Mystriosuchus Westphali, With A Revision of the Genus
This study demonstrates that a detailed analysis of the cranial anatomy and the rigorous application of cladistic principles to identified character states help to clarify current inconsistencies in the taxonomy and nomenclature of phytosaurs.

A new locality in the middle Keuper marly clays with excellently preserved tetrapod skeletons was discovered at Krasiej?w near Opole, southern Poland (Dzik et al., 2000). It has yielded abundant
A New Phytosaur (Archosauriformes, Phytosauria) from the Lot's Wife Beds (Sonsela Member) within the Chinle Formation (Upper Triassic) of Petrified Forest National Park, Arizona
ABSTRACT A new phytosaur taxon from Petrified Forest National Park, Arizona, is here described based on cranial material from a single individual. This specimen previously was included in an
The taxonomic status of the phytosaurs (Archosauriformes) Machaeroprosopus and Pseudopalatus from the Late Triassic of the western United States
It is demonstrated that M. buceros is the correct type species, not M. validus, and the genus level name Machaeroprosopus has priority over the genera Pseudopalatus and Arribasuchus and all nominal species should be reassigned.
The Early Evolution of Archosaurs: Relationships and the Origin of Major Clades
A time-calibrated phylogeny of Archosauriformes indicates that the origin and initial diversification of archosauria occurred during the Early Triassic following the Permian-Triassic extinction.
The importance of the critical fossils seems to reside in their relative primitive‐ness, and the simplest explanation for their more conservative nature is that they have had less time to evolve.
