The Cranial Anatomy and Relationships of Cardiocorax Mukulu (Plesiosauria: Elasmosauridae) From Bentiaba, Angola [PDF]

PLoS ONE, 2021
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 nature of the skull offers rare insight into the cranial anatomy of elasmosaurid ...

Redescription of Tuarangisaurus Keyesi (Sauropterygia; Elasmosauridae), a Key Species From the Uppermost Cretaceous of the Weddellian Province: Internal Skull Anatomy and Phylogenetic Position

Cretaceous Research, 2017
Abstract The systematics of elasmosaurids are not well resolved partially because of the scarcity of well-preserved skull material. Among Weddellian elasmosaurids, one exception to this is the holotype of Tuarangisaurus keyesi from upper Campanian–lower Maastrichtian levels of the Maungataniwha Sandstone Member of the Tahora Formation, Mangahouanga ...
