ABSTRACT A rostrum fragment from the marginal marine upper Lunz Formation of Austria (early Late Triassic: late Carnian) was previously identified as a new species of phytosaurian archosauriform, ‘Francosuchus’ trauthi. ‘Francosuchus’ trauthi was subsequently synonymized with the non-phytosaurid phytosaur Paleorhinus, and this synonymy was used as evidence to correlate the ‘Paleorhinus biochron’ and the Otischalkian land-vertebrate faunachron to the marine timescale. Here, I provide a… 
Redescription of the phytosaurs Paleorhinus (‘Francosuchus’) angustifrons and Ebrachosuchus neukami from Germany, with implications for Late Triassic biochronology
TLDR
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 Short-Snouted, Middle Triassic Phytosaur and its Implications for the Morphological Evolution and Biogeography of Phytosauria
TLDR
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.
Description and phylogenetic placement of a new marine species of phytosaur (Archosauriformes: Phytosauria) from the Late Triassic of Austria
TLDR
A new species of the phytosaur genus Mystriosuchus is described from the Norian Dachstein Limestone of Austria, from a marine lagoonal depositional environment, providing the strongest evidence to date of marine adaptations in phytosaurs.
Phytosauria
Abstract Phytosauria is a nearly cosmopolitan clade of large, quadrupedal, carnivorous archosauriforms. They are known unambiguously from Late Triassic deposits, although the clade’s ghost lineage
A remarkable group of thick‐headed Triassic Period archosauromorphs with a wide, possibly Pangean distribution
TLDR
The integrated analysis further demonstrates that there are many ways to create a dome in Amniota and suggests that these ‘dome‐headed’ archosauromorphs were widespread and are likely part of more assemblages than currently recognized.
Corrigendum: A Short-Snouted, Middle Triassic Phytosaur and its Implications for the Morphological Evolution and Biogeography of Phytosauria
TLDR
This corrects the article DOI: 10.1038/srep46028 to indicate that the author of the paper is a doctor of medicine rather than a scientist, as previously reported.

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
TLDR
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.
First record of Mesozoic terrestrial vertebrates from Lithuania: phytosaurs (Diapsida: Archosauriformes) of probable Late Triassic age, with a review of phytosaur biogeography
Abstract Fossils of Mesozoic terrestrial vertebrates from Lithuania and the wider East Baltic region of Europe have previously been unknown. We here report the first Mesozoic terrestrial vertebrate
A NEW SPECIES OF THE LATE TRIASSIC PHYTOSAUR PSEUDOPALATUS ( ARCHOSAURIA : PSEUDOSUCHIA ) FROM PETRIFIED FOREST NATIONAL PARK , ARIZONA
TLDR
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 status and phylogenetic relationships of “Zanclodon”arenaceus: the earliest known phytosaur?
TLDR
A cladistic analysis identified “Z.”arenaceus as the sister-taxon of Phytosauria, but because of the limited data available and numerous homoplasies that occur among mandibular characters of archosaurs a closer relationship with other archosaur taxa is a reasonable alternative.

TLDR
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 giant skull, ontogenetic variation and taxonomic validity of the Late Triassic phytosaur Parasuchus
TLDR
The largest known specimen of this primitive taxon, an incomplete skull from the Popo Agie Formation in northwestern Wyoming, demonstrates that the nares remain anterior to the antorbital fenestra throughout the ontogeny of Parasuchus, an observation confirmed by an analysis of a broad database.
FIRST RECORD OF NILSSONIOPTERIS (GYMNOSPERMOPHYTA, BENNETTITALES) FROM THE CARNIAN (UPPER TRIASSIC) OF LUNZ, LOWER AUSTRIA
TLDR
The discovery of Nilssoniopteris further substantiates the significance of the Lunz flora as one of the richest and most diverse early Late Triassic floras from the Northern Hemisphere.
