Abstract We examined the osteology of Neogene Alligator, with a focus on fossils from the late Miocene (~8–7 million years ago [Ma]) Moss Acres Racetrack locality in Marion County, Florida, USA. These fossils have been referred previously to Alligator cf. A. mefferdi (early late Miocene, ~12–10 Ma, Nebraska), an extinct species that we and others have found to be lacking autapomorphic characters. Furthermore, numerous cranial polymorphisms, previously regarded as diagnostic autapomorphies or…

Redescription and phylogenetic affinities of the caimanine Eocaiman cavernensis (Crocodylia, Alligatoroidea) from the Eocene of Argentina
TLDR
A reassessment of E. cavernensis is presented, based on first‐hand examination and micro‐computed tomography of the holotype, and some aspects of its morphology are reinterpreted, providing evidence for a monophyletic Eocaiman genus within Caimaninae, even though some highly incomplete taxa represent significant sources of phylogenetic instability.
A new caimanine (Crocodylia, Alligatoroidea) species from the Solimões Formation of Brazil and the phylogeny of Caimaninae
TLDR
A phylogenetic analysis of Eusuchia showed the new Caimanine pachytemporalis as sister to Purussaurus, which allows discussion about the evolution of gigantism in the Acresuchus-Purussaurus clade, which reveals several characters that may be related to giganism.
Neogene Crocodylians from the Central Great Plains: Spatiotemporal Histories and Relationships with Regional Climatic and Environmental Changes
ABSTRACT Crocodylian fossils are well documented from Upper Cretaceous and lower to middle Paleogene deposits in the mid-high latitudes of the Western Interior, whereas the only extant North American…

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.

The Lapara Creek Fauna includes a large collection of fossil vertebrates obtained by the State-Wide Paleontologic-Mineralogic Survey in Texas (1939–1941) under the direction of the Bureau of Economic…
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.
SOME THOUGHTS ON INTERSPECIFIC MANDIBULAR MORPHOLOGY IN FOSSIL AND MODERN ALLIGATOR
TLDR
The genus Alligator has historically been used for nearly any blunt-snouted (brevirostrine) crocodylomorph and has been greatly constrained in its modern application via Brochu, 1999 and 2004, such that species within the genus possess the following shared osteological traits.
Spatiotemporal palaeodiversity patterns of modern crocodiles (Crocodyliformes: Eusuchia)
TLDR
These estimates reveal complex spatiotemporal palaeodiversity patterns, in which two maxima can be detected: the first during the Palaeocene and the second, which is also the biggest, in the middle-late Miocene.

First Fossil Alligator from the Late Eocene of Nebraska and the Late Paleogene Record of Alligators in the Great Plains
TLDR
Results from a cladistic analysis of 28 alligatoroid species using 181 morphological characters support the identification of the new specimens as representing the most basally divergent taxon within Alligator, suggesting that they likely represent A. prenasalis, but a lack of diagnostic features in the Nebraska specimens prevents a definitive assignment to this species.
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.

TLDR
Preliminary comparisons suggest that Brachychampsa and its sister taxon Alberto champsa langstoni form a natural group with all alligatoroids except Diplocynodon hantoniensis, but there is no evidence placing the species within the Alligatoridae.

TLDR
A revised phylogenetic analysis supports multiple dispersal events of alligatorines from North America to Eurasia, and suggests that the cranial anatomy thought to distinguish forms such as Allognathosuchus is plesiomorphic at the level of Alligatoridae.

Phylogenetic relationships of Necrosuchus ionensis Simpson, 1937 and the early history of caimanines
TLDR
Although the authors cannot yet pinpoint the phylogenetic placement of Necrosuchus amongst caimans, it nevertheless establishes a caimanine presence in South America by the Early Palaeocene, suggesting multiple dispersal events between North and South America, even if the modern caiman assemblage is monophyletic.
