Abstract The discovery of new specimens of Pachyvaranus crassispondylus Arambourg, 1952 from the Maastrichtian phosphates of Morocco and Syria enables us to (1) redescribe in detail this poorly known varanoid lizard, (2) provide a more detailed diagnosis and (3) re-evaluate the systematic affinities of this taxon within squamates. The latter is placed in Pachyvaranidae nov., considered a new unranked clade of non-pythonomorph Varanoidea. The intense pachyosteosclerosis observed in the vertebrae… 
Reptilian assemblages from the latest Cretaceous – Palaeogene phosphates of Morocco: from Arambourg to present time
Arambourg was the first to conduct methodical vertebrate palaeontological studies in the Oulad Abdoun and Ganntour phosphatic basins of Morocco between the 1930s and 1950s. As early as 1935, he
Mosasaurids (Squamata) from the Maastrichtian Phosphates of Morocco: Biodiversity, palaeobiogeography and palaeoecology based on tooth morphoguilds ☆
Mosasaurid squamates are the most numerically abundant, and taxonomically/ecologically diverse clade of marine amniotes represented in the Maastrichtian Phosphates of Morocco and can be placed into resource partitioning morphoguilds indicative of adaptations for piercing, crushing or cutting.
New highlights about the enigmatic marine snake Palaeophis maghrebianus (Palaeophiidae; Palaeophiinae) from the Ypresian (Lower Eocene) phosphates of Morocco
Palaeophis maghrebianus belongs to the Palaeo- phiinae (Palaeophiidae). This snake subfamily is relatively poorly known, and it is mainly represented by disarticulated vertebrae and ribs and by a few
Maastrichtian marine reptiles of the Mediterranean Tethys: a palaeobiogeographical approach
A global comparison of coeval Maastrichtian marine reptiles (squamates, plesiosaurs, chelonians and crocodyliformes) of Europe, New Jersey, northwestern Africa and Middle-East has been performed.
The First Freshwater Mosasauroid (Upper Cretaceous, Hungary) and a New Clade of Basal Mosasauroids
Pannoniasaurus inexpectatus uniquely possesses a plesiomorphic pelvic anatomy, a non-mosasauroid but pontosaur-like tail osteology, possibly limbs like a terrestrial lizard, and a flattened, crocodile-like skull.
Reworked marine pythonomorph (Reptilia, Squamata) remains in Late Pleistocene cave deposits in central Spain
Three sites at the Calvero de la Higuera complex (Camino Cave, Navalmaillo Rock Shelter, and Buena Pinta Cave), near the village of Pinilla del Valle (Madrid, Spain), are known for their record of
Marine vertebrate faunas from the Maastrichtian phosphates of Benguérir (Ganntour Basin, Morocco): Biostratigraphy, palaeobiogeography and palaeoecology
A possible signal of an environmental damage affecting the predator community can be noted by faunal turnovers, even if no significant change in prey association was clearly detected, as testified by the rapid increase of marine predator density in the Maastrichtian.
Necrosaurus or Palaeovaranus? Appropriate nomenclature and taxonomic content of an enigmatic fossil lizard clade (Squamata)
Abstract Necrosaurus cayluxi is an enigmatic lizard from the Paleogene of the Phosphorites of Quercy, France that was first mentioned in the 19th century. Although it is generally believed that
Rediscovery of “Liodon” asiaticum Répelin, 1915, a Mosasaurini (Squamata, Mosasauridae, Mosasaurinae) from the Upper Cretaceous of the vicinity of Jerusalem – Biostratigraphical insights from microfossils
Briefl y mentioned in 1915 by the palaeontologist Répelin, the mosasaurid Liodon asiaticum Répelin, 1915 was found by a missionary to Africa, Father Ruffi er, in Late Cretaceous strata near Jerusalem
Maroccosuchus zennaroi (Crocodylia: Tomistominae) from the Eocene of Morocco: phylogenetic and palaeobiogeographical implications of the basalmost tomistomine
A phylogenetic analysis including 64 ingroup taxa and 238 characters reveals that M. zennaroi is the basalmost tomistomine, and clearly indicates a Lower Eocene, and no older than Late Palaeocene age for the tomistsomine emergence, questioning the Late E epochs, Oligocene and Miocene ages proposed for Gavialis–Tomistoma divergence by molecular analyses.


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
A new species of Halisaurus from the Late Cretaceous phosphates of Morocco, and the phylogenetical relationships of the Halisaurinae (Squamata: Mosasauridae)
A new species of the basal mosasaurid Halisaurus from the Late Cretaceous (Late Maastrichtian) of the Oulad Abdoun Phosphate Basin of Morocco is described on the basis of both cranial and postcranial
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 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.
Durophagous Mosasauridae (Squamata) from the Upper Cretaceous phosphates of Morocco, with description of a new species of Globidens
Abstract Three durophagous mosasaur species are represented by isolated teeth in the Upper Cretaceous (Maastrichtian) phosphatic beds of Morocco. Globidens phosphaticus nov. sp. is characterised
The paleobiology of Dolichosaurus is reconstructed as similar to coniasaurs, nothosaurs, and modern sea snakes and hypapophyses are found more informative regarding taxic differences and transformational scenarios.
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
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).
Mosasaurus beaugei Arambourg, 1952 (Squamata, Mosasauridae) from the Late Cretaceous phosphates of Morocco
Mosasaurus beaugei Arambourg, 1952 was based on isolated teeth from the Maastrichtian phosphatic deposits of Morocco. The recent discovery of new material, including skull and mandibular remains,
"Pachyostosis" in aquatic amniotes: a review.
The functional consequences of "pachyostosis," and notably its importance for buoyancy control in the context of hydrostatic regulation of the body trim, are discussed and opposed to the requirement of improved swimming abilities in the case of a hydrodynamic mode of trim regulation.
