Osteology of Tyrannosaurus Rex: Insights from a nearly complete Skeleton and High-Resolution Computed Tomographic Analysis of the Skull
TLDR
High-resolution x-ray computed tomographic analysis of the skull reveals internal details not previously observed, raising several possibilities, including the complete absence of a bony sternum in tyrannosaurids.
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.
PHYLOGENETIC APPROACHES TOWARD CROCODYLIAN HISTORY
▪ 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
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.
Closure of neurocentral sutures during crocodilian ontogeny: Implications for maturity assessment in fossil archosaurs
TLDR
Closure of cervical sutures is a consistent indicator of morphological maturity in Alligator mississippiensis, Alligator sinensis, Osteolaemus tetraspis, and Crocodylus acutus; however, it is not certain if suture closure indicates the stoppage of growth.
A pug-nosed crocodyliform from the Late Cretaceous of Madagascar
TLDR
An exquisitely preserved specimen of a new taxon from the Late Cretaceous of Madagascar is reported, possessing an extremely blunt snout, a tall, rounded skull, an anteriorly shifted jaw joint and clove-shaped, multicusped teeth reminiscent of those of some ornithischian dinosaurs.
Crocodylian Snouts in Space and Time: Phylogenetic Approaches Toward Adaptive Radiation1

  • 1 June 2001
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 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.
A review of “Leidyosuchus” (Crocodyliformes, Eusuchia) from the Cretaceous through Eocene of North America
TLDR
A review of all described species referred to Leidyosuchus recognizes six valid taxa; this group is related to, but not within, a monophyletic group that includes Alligatoroidea and Crocodyloidea, and a close relationship between these taxa and Diplocynodon is rejected.
Gigantism and comparative life-history parameters of tyrannosaurid dinosaurs
TLDR
Growth patterns within the Tyrannosauridae are studied and it is determined that Tyrannosaurus rex's great stature was primarily attained by accelerating growth rates beyond that of its closest relatives.
