Early Crocodylomorpha

  title={Early Crocodylomorpha},
  author={Randall B. Irmis and Sterling J. Nesbitt and Hans‐Dieter Sues},
Abstract Non-crocodyliform crocodylomorphs, often called ‘sphenosuchians’, were the earliest-diverging lineages of Crocodylomorpha, and document the stepwise acquisition of many of the features that characterize extant crocodylians. The first crocodylomorph fossils are approximately 230 million years old (upper Carnian, Late Triassic), and at least one of these early lineages persisted until at least 150 million years ago (Late Jurassic). These taxa occupied a wide variety of terrestrial…

Characterising macroevolutionary patterns within crocodylomorpha

Body size patterns and patterns of cranial shape variation suggest an important link between ecological diversification and morphological disparity, and represent a significant contribution to better understanding crocodylomorph phenotypic evolution.

The multi-peak adaptive landscape of crocodylomorph body size evolution

Shifts between macroevolutionary regimes provide a better explanation of crocodylomorph body size evolution than do climatic factors, suggesting a central role for lineage-specific adaptations rather than climatic forcing.

A juvenile subfossil crocodylian from Anjohibe Cave, Northwestern Madagascar

This specimen clearly represents a juvenile based on the extremely small size and open sutures/detached neural arches; total body length is estimated to be ∼1.1 m (modern adults of this species range from ∼4–6 m).

An early-diverging crocodylomorph from the early Norian (Late Triassic) of Texas demonstrates a wide distribution of early members across low-latitude Pangea

Crocodylomorpha, the pseudosuchian lineage including all taxa more closely related to crown Crocodylia than to phytosaurs, ornithosuchids, aetosaurs, poposauroids, and rauisuchids (Nesbitt, 2011;

First and most northern occurrence of a thalattosuchian crocodylomorph from the Jurassic of the Isle of Skye, Scotland

The Jurassic was a key interval for the evolution of dinosaurs, crocodylomorphs and many other vertebrate groups. In recent years, new vertebrate fossils have emerged from the Early–Middle Jurassic

Body Size Evolution in Crocodylians and Their Extinct Relatives

Crocodylians are currently facing evolutionary decline. This is evinced by the rich fossil record of their extinct relatives, crocodylomorphs, which show not only significantly higher levels of

Convergence and functional evolution of longirostry in crocodylomorphs

Compared to Gavialis, Pelagosaurus was unable to process large, mechanically less tractable prey, instead operating as a specialized piscivore that fed on softer and smaller prey, and different rates of functional evolution suggest divergent diversification dynamics between teleosaurids and metriorhynchids in the Jurassic.

Spatiotemporal sampling patterns in the 230 million year fossil record of terrestrial crocodylomorphs and their impact on diversity

The 24 extant crocodylian species are the remnants of a once much more diverse and widespread clade. Crocodylomorpha has an approximately 230 million year evolutionary history, punctuated by a series




Abstract We describe a new fossil crocodyliform archosaur from the Early Jurassic Kayenta Formation of the Navajo Nation that is surprisingly derived for so ancient a specimen. High-resolution X-ray

A giant crocodylomorph from the Upper Triassic of New Mexico

A new genus and species of giant crocodylomorph from the Upper Triassic of New Mexico is described, and key characters suggest a phylogenetic position near the base of Sphenosuchia.

A Middle Jurassic ‘sphenosuchian’ from China and the origin of the crocodylian skull

Important features of the modern crocodylian skull evolved during a phase when the postcranial skeleton was evolving towards greater cursoriality, rather than towards their current semi-aquatic habitus.

A New Gobiosuchid Crocodyliform Taxon from the Cretaceous of Mongolia

A phylogenetic analysis indicated that Z. shepardi shares numerous derived characters with Gobiosuchus kielanae, and these two taxa form a monophyletic group located basally among crocodyliforms.

Phylogeny of the Crocodylotarsi, with reference to archosaurian and crurotarsan monophyly

The phylogeny of the Crocodylotarsi was re-examined based on study of most relevant fossil material of the early non–crocodyliform members of the clade.

Morphology of the Late Cretaceous Crocodylomorph Shamosuchus djadochtaensis and a Discussion of Neosuchian Phylogeny as Related to the Origin of Eusuchia

A review of all the available evidence on the diversity of advanced neosuchians suggests this group achieved a worldwide distribution and a remarkable morphological diversity, pushing their evolutionary origins back to the Jurassic.

Procompsognathus: theropod, “thecodont” or both?

ABSTRACT We show that Procompsognathus triassicus, long held to be a primitive theropod, is actually a paleontological chimera composed of the postcranial skeleton of a Segisaurus-like ceratosaur and

Phylogenetic and morphometric assessment of the evolution of the longirostrine crocodylomorphs

The results presented here indicate that crocodyliform disparity peaked in the Late Cretaceous followed by a dramatic decline in the Maastrichtian (preceding the end-Cretaceous extinction), and the emptied region of morphospace, exemplified by a short and narrow snout, was never explored by crown-group croc Codylians.


▪ 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

Ecologically distinct dinosaurian sister group shows early diversification of Ornithodira

The analysis suggests that the dentition and diet of silesaurids, ornithischians and sauropodomorphs evolved independently from a plesiomorphic carnivorous form, and Asilisaurus demonstrates the antiquity of both Ornithodira and the dinosaurian lineage.
