THE ELASMOSAURID PLESIOSAUR ARISTONECTES CABRERA FROM THE LATEST CRETACEOUS OF SOUTH AMERICA AND ANTARCTICA
The dental morphology and peculiar occlusal pattern, forming an interlocking trap, suggest that Aristonectes strained a diet of small, soft organisms from the water.
a new elasmosaurid plesiosaur from the Lower Jurassic of southern France
Plesiosaurus tournemirensis Sciau, Crochet and Mattei, based on a nearly complete skeleton with skull from the Upper Toarcian (Lower Jurassic) of Tournemire (Aveyron Department, southern France), is…
A NEW ICHTHYOSAUR FROM THE UPPER JURASSIC LITHOGRAPHIC LIMESTONES OF BAVARIA
A new genus, Aegirosaurus, is created and proposed as a new combination for this species, which clearly belongs to the clade Ophthalmosauria because of an angular largely exposed laterally and reaching as far anteriorly as the surangular.

The fossil record of marine reptiles is punctuated by two major extinctions at the Middle‐Late Triassic transition and the K/T boundary, characterized by selective extinctions among marine reptiles, probably linked with a break in the food chain.
A new mosasauroid (Squamata) from the Late Cretaceous (Turonian) of Morocco
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…

It is shown that ichthyosaurs maintained high but diminishing richness and disparity throughout the Early Cretaceous, and that global environmental change resulted in a major, temporally staggered turnover event that profoundly reorganized marine ecosystems during the Cenomanian.

The taxonomic diversity of late Albian ichthyosaurs now matches that of older, well-known intervals such as the Toarcian or the Tithonian, suggesting strong geographical disparities in the diversity pattern of Albian–early Cenomanian ICHthyosaurs.
Zarafasaura oceanis, a new elasmosaurid (Reptilia: Sauropterygia) from the Maastrichtian Phosphates of Morocco and the palaeobiogeography of latest Cretaceous plesiosaurs
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…
