The terrestrial origins of the diapsid Sauropterygia and Testudines are uncertain, with the
latter being highly controversially discussed to this day. For only 15 Ma, Nothosauroidea …

The holotype of Libonectes atlasense is an almost complete skeleton from Upper
Cretaceous (mid-Turonian) rocks of the Goulmima area in eastern Morocco. Initial …

The holotype of the elasmosaurid Aphrosaurus furlongi from the Maastrichtian levels of the
Moreno Formation is redescribed and considered a valid species based on one …

The jigsaw-puzzle fit of South America and Africa is an icon of plate tectonics and
continental drift. Fieldwork in Angola since 2002 allows the correlation of onshore outcrops …

Plesiosauria is a diverse clade of marine reptiles that have been studied since the early 19th
century. However, phylogenetic relationships within the group have been contentious due to …

Two extremely-long necked elasmosaurids, AMNH 1495, holotype of Hydralmosaurus
serpentinus, and AMNH 5835, previously referred to H. serpentinus, are here reviewed in …

We report a new specimen of the plesiosaur Cardiocorax mukulu that includes the most
complete plesiosaur skull from sub-Saharan Africa. The well-preserved three-dimensional …

New elasmosaurid plesiosaur specimens are described from the Early Maastrichtian of
Angola. Phylogenetic analyses reconstruct the Angolan taxon as an aristonectine …

Plesiosaurian marine reptiles evolved a wide range of body shapes during the Jurassic and
Cretaceous, including long-necked forms. Many Late Cretaceous members of the clade …

The diapsid plesiosaurs were pelagic and inhabited the oceans from the Triassic to the
