Abstract The study of the so-called vertebral ‘pachyostosis’ of Carentonosaurus mineaui, a plesiopedal mosasauroid sensu Bell & Polcyn from the Cenomanian (Late Cretaceous) of Charente-Maritime (Western France), has revealed that it actually corresponds to pachyosteosclerosis resulting from the combination of cortical hyperplasy with bone compaction due to an inhibition of chondroclastic and osteoclastic activities. This characteristic also occurs in other Cretaceous squamates such as… 

Evolution of Sirenian Pachyosteosclerosis, a Model-case for the Study of Bone Structure in Aquatic Tetrapods

To document how these features differentiated during sirenian evolution, the ribs of 15 species, from the most basal form (Pezosiren portelli) up to extant taxa, were studied and compared to those of other mammalian species from both morphometric and histological points of view.

A combined morphological and microanatomical analysis of vertebrae and ribs of these fossil squamates provides new data about the distribution and variability of this osseous specialization in these taxa.

What Vertebral Microanatomy Reveals About the Ecology of Juvenile Mosasaurs (Reptilia, Squamata)

This study tends to support recent views challenging the old hypothesis of sheltered nurseries and shows that, in mosasauroids, the functional requirements for buoyancy and body trim control are not correlated with individual size.

Early eusuchia crocodylomorpha from the vertebrate‐rich Plattenkalk of Pietraroia (Lower Albian, southern Apennines, Italy)

Pietraroiasuchus ormezzanoi resolves the phylogenetic position of the controversial P. trinquei, and is crucial in enabling an extensive understanding of the family Hylaeochampsidae.

The intermediary pattern observed in Tethysaurus suggests a progressive change in vertebral microanatomy reflecting the ecological shift that occurred during the evolution of the group.

Structural, functional, and physiological signals in ichthyosaur vertebral centrum microanatomy and histology

The main switch in microanatomical organization appears to be correlated to the acquisition of deeply amphicoelous disk-like vertebral centra rather than to a shift in swimming mode from long and slender-bodied anguilliform swimmers to thunniform swimming.

A new fossil marine lizard with soft tissues from the Late Cretaceous of southern Italy

A new marine lizard showing exceptional soft tissue preservation was found in Late Cretaceous deposits of the Apulian Platform (Puglia, Italy). Primitivus manduriensis gen. et sp. nov. is not only



Specialization of bone structure in Pachyvaranus crassispondylus Arambourg, 1952, an aquatic squamate from the Late Cretaceous of the southern Tethyan margin

The histological organization of the vertebrae of the Maastrichtian squamate Pachyvaranus crassispondylus Arambourg, 1952, was compared to that of various extant squamates, in order to further

A new pachyostotic squamate reptile from the Cenomanian of France

Cenomanian beds from western France have yielded a new pythonomorph squamate (Reptilia) that is described here as Carentonosaurus mineaui gen. et sp. nov. This fossil is referred to non‐mosasaurid


Both the strict consensus tree and the 50% majority-rule consensus tree found support for the monophyly of the Pythonomorpha, containing mosasaurs, aigialosaurs, dolichosaurs, and snakes (pachyophiids and modern snakes).

Dallasaurus turneri, a new primitive mosasauroid from the Middle Turonian of Texas and comments on the phylogeny of Mosasauridae (Squamata)

A new genus and species of primitive-limbed mosasauroid, Dallasaurus turneri, from the Middle Turonian of north-central Texas, is described on the basis of two incomplete skeletons and retains plesiomorphic characters but also exhibits certain characters shared with derived mosasaurs of the subfamily Mosasaurinae.


Phylogenetic analysis of 258 osteological characters and all the major squamate lineages suggests that Adriosaurus and dolichosaurs are successive sister-taxa to snakes, refuting recent suggestions that snakes cluster with amphisbaenians and dibamids (rather than aquatic lizards) if multistate characters are left unordered.

The marine vertebrate faunas from the Late Cretaceous phosphates of Syria

Marine vertebrate faunas from the latest Cretaceous phosphates of the Palmyrides Chain of Syria are described for the first time. Recent fieldwork in the phosphatic deposits of the Palmyra area

A second primitive marine snake: Pachyophis woodwardi from the Cretaceous of Bosnia‐Herzegovina

A cladistic analysis demonstrates that Pachyophis and Pachyrhachis form a clade that forms the most basal group of snakes so far known and is the sister group to all other well-known snakes.

The Cretaceous marine squamate Mesoleptos and the origin of snakes

Phylogenetic analysis suggests that Mesoleptos is the nearest relative of snakes; this phylogenetic position is consistent with its morphology being intermediate between typical marine squamates (e.g. mosasauroids) and primitive marine snakes (pachyophiids).

Functional significance of bone ballastin in the evolution of buoyancy control strategies by aquatic tetrapods

Biomechanical considerations lead to the prediction that a new marine tetrapod clade will typically evolve bone ballast as part of its adaptation to life in water.
