On a Longirostrine Crocodylomorph (Thalattosuchia) From the Middle Jurassic of Tunisia

Geobios, 2019
Abstract The geographic origins and distributional patterns of Gondwanan teleosauroids during the Jurassic have been fiercely debated over many years. Unlike the rich thalattosuchian fossil record from Laurasia, teleosauroids described from Gondwanan ecosystems are relatively scarce.

The skull of Teleosaurus cadomensis (Crocodylomorpha; Thalattosuchia), and phylogenetic analysis of Thalattosuchia

Journal of Vertebrate Paleontology, 2009
ABSTRACT Several Teleosaurus skulls were described during the nineteenth century. Unfortunately, all skulls from this genus were destroyed during World War II. The only available skull is currently preserved in the MNHN. Thanks to a new preparation, new anatomical features can be seen, such as the morphology of the nasal cavity, the external otic ...

Bone histology as a clue in the interpretation of functional adaptations in the Thalattosuchia (Reptilia, Crocodylia)

Journal of Vertebrate Paleontology, 1996
ABSTRACT The histological study of various bones in the families Teleosauridae and Metriorhynchidae reveals common, but also contrasting structural features of the skeleton. Both display a zonal pattern of bone tissue, suggesting a cyclic growth and an ecto-poikilothermic physiology, quite similar to those of recent crocodiles.

A New Metriorhynchoid (Crocodylomorpha, Thalattosuchia) From the Middle Jurassic of Oregon and the Evolutionary Timing of Marine Adaptations in Thalattosuchian Crocodylomorphs

open access: yesJournal of Vertebrate Paleontology, 2015
Metriorhynchid thalattosuchians represent the most extreme archosaurian adaptation to the marine realm. Metriorhynchids possess aquatic adaptations throughout the skeleton.

The tailbend of Metriorhynchidae (Crocodylia: Thalattosuchia) measurements, limits and paleoecological implications

PalZ
Although the remains of Metriorhynchidae have been known in Normandy since the nineteenth century, few complete postcranial elements have been studied in detail. Analysis of the angle of flexure of the tail of one of the most complete specimens of Metriorhynchus aff. superciliosus (MPV 2010.3.610) discovered in the Callovian of the Vaches-Noires cliffs
