▪ Abstract A review of crocodylian phylogeny reveals a more complex history than might have been anticipated from a direct reading of the fossil record without consideration of phylogenetic relationships. The three main extant crocodylian lineages—Gavialoidea, Alligatoroidea, Crocodyloidea—are known from fossils in the Late Cretaceous, and the group is found nearly worldwide during the Cenozoic. Some groups have distributions that are best explained by the crossing of marine barriers during the… 
A TIME‐CALIBRATED SPECIES TREE OF CROCODYLIA REVEALS A RECENT RADIATION OF THE TRUE CROCODILES

TLDR
Traditional views of the evolution of Crocodylus are overturned by demonstrating that the true crocodiles are not “living‐fossils” that originated in Africa, and rapidly radiated and dispersed around the globe during a period marked by mass extinctions of fellow crocodylians.
Three crocodilian genomes reveal ancestral patterns of evolution among archosaurs
TLDR
An exceptionally slow rate of genome evolution within crocodilians at all levels is observed, consistent with a single underlying cause of a reduced rate of evolutionary change rather than intrinsic differences in base repair machinery.
The phylogenetic relationships of neosuchian crocodiles and their implications for the convergent evolution of the longirostrine condition
TLDR
A new dataset for the crocodylomorph clade Neosuchia is presented, consisting of 569 morphological characters for 112 taxa and shows that equally weighted parsimony and Bayesian methods cluster unrelated longirostrine forms together, producing a topology that conflicts strongly with their stratigraphic distributions.
Phylogenetic analysis of a new morphological dataset elucidates the evolutionary history of Crocodylia and resolves the long-standing gharial problem
TLDR
A new morphological dataset for Crocodylia is presented based on a critical reappraisal of published crocodylian character data matrices and extensive firsthand observations of a global sample of croc Codylians, which robustly recover Gavialis as more closely related to Tomistoma than to other extant cro codylians for the first time based on morphology alone.
Modern cryptic species and crocodylian diversity in the fossil record
TLDR
Ranges of variation in modern species require a thorough re-evaluation, and the authors may have to revisit previous perceptions of past crocodyliform diversity, rates of evolution or anagenetic lineages in stratigraphic succession.
A multi-disciplinary approach to the analysis of crocodylian phylogeny, diversity and biogeographic history in Deep Time
TLDR
Character tracing reveals that similar modifications in the anterior of the skull underpin the evolution of longirostry in all clades, coupled with more clade-specific modifications of the posterior skull, which played an important role in neosuchian evolution.
True and false gharials: a nuclear gene phylogeny of crocodylia.
TLDR
The causes of discrepancy between molecular and morphological estimates of crocodylian phylogeny are explored and puzzling features of the morphological data are examined using a priori partitions of the data based on anatomical regions and the effects of different coding schemes for two obvious morphological similarities of the two gharials are investigated.
Trait‐based range expansion aided in the global radiation of Crocodylidae
TLDR
Interestingly, the evolution of the range‐expansion phenotype was also associated with the diversification of the genus in a period of global crocodilian extinction, indicating that range expansion might have served as a potential driver of speciation.

Crocodylian Snouts in Space and Time: Phylogenetic Approaches Toward Adaptive Radiation1
  • C. Brochu

TLDR
The phylogenetic analyses of fossil and living crocodylians allow us to compare the taxonomic, geographic, and temporal distributions of morphological features, such as snout shapes, which tend to be more endemic than composite faunas of the early Tertiary.
Phylogenetic Relationships and Divergence Timing of Crocodylus Based on Morphology and the Fossil Record
TLDR
Maximum parsimony analysis of 164 morphological characters supports the monophyly of crown-genus Crocodylus relative to other extant lineages, and monophyletic New World and Indopacific assemblages are supported.
The Higher Level Relationships of the Extant Crocodylia
-The relationships of the three living groups of crocodilians (crocodylids, alligatorids and gavialids) are poorly understood. Recent molecular results favor a sister group relationship between the
The Systematics and Evolution of the Crocodilia as Suggested by Restriction Endonuclease Analysis of Mitochondrial and Nuclear Ribosomal DNA
TLDR
This first extensive molecular phylogeny of the true crocodiles not only aligns some species that are found in the same hemisphere but also places organisms that currently have disjunct distributions in the the same clade.
True and false gharials: a nuclear gene phylogeny of crocodylia.
TLDR
The causes of discrepancy between molecular and morphological estimates of crocodylian phylogeny are explored and puzzling features of the morphological data are examined using a priori partitions of the data based on anatomical regions and the effects of different coding schemes for two obvious morphological similarities of the two gharials are investigated.
Morphology, fossils, divergence timing, and the phylogenetic relationships of Gavialis.
TLDR
Fossils strongly contradict a post-Oligocene divergence between Gavialis and any other living crocodylian, but the phylogenetic placement of GAVialis is best viewed as unresolved.

Phylogenetics, Taxonomy, and Historical Biogeography of Alligatoroidea
TLDR
Parsimony analysis of 164 discrete morphological characters supports several previous hypotheses based on morphology and molecules that Alligatoroidea is a monophyletic alligatoroid lineage and the paraphyly of “Allognathosuchus” is indicated.
The Evolution of the Crocodilia: A Conflict Between Morphological and Biochemical Data
TLDR
New morphological studies have shown that the braincase structure, neural pocket, air sinus systems, jaw adductor mechanisms, pelvic and hindlimb morphology and epaxial musculature of the caudal region of Gavialis gangeticus do not correspond to the rest of the living Eusuchia.
The Phylogenetic Position of Cetaceans: Further Combined Data Analyses, Comparisons with the Stratigraphic Record and a Discussion of Character Optimization1
TLDR
A previous total evidence analysis of the position of cetaceans was updated by adding several hundred new informative molecular characters from the literature, finding that all most parsimonious trees indicate a paraphyletic Artiodactyla with conflict existing over the exact sister taxon of Cetacea.
