Anguanax
Anguanax is the first articulated plesiosaur ever found in Italy. It is a basal thalassophonean pliosaur from the Late Jurassic (middle Oxfordian). The type and only known specimen (MPPL 18797) of Anguanax was originally described as an indeterminate pliosaurid (Cau and Fanti 2014), but was subsequently named after reanalysis by the same authors the following year (Cau and Fanti 2015).

Colymbosaurus is a colymbosaurine (derived cryptoclidid) from the Late Jurassic of the UK and Svalbard, Norway. Two valid species are known, C. megadeirus from the UK, and C. svalbardensis from Svalbard, Norway. Benson and Bowdler (2014) revised the genus Colymbosaurus and summarised its complicated history:
“Seeley (1869) (p.97-101) listed two partial postcranial skeletons from the Kimmeridge Clay Formation of Ely…and Haddenham… in Cambridgeshire as belonging to a new species, Plesiosaurus megadeirus Seeley 1869. P.
