Colymbosaurus
Left hindlimb of Colymbosaurus megadeirus (CAMSM J.29596etc), modified from Benson and Bowdler (2014)
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. The genus is known from the Kimmeridgian, Tithonian, and possibly early Berriasian (Late Jurassic–possibly Early Cretaceous). Benson and Bowdler (2014) revised the genus Colymbosaurus and summarised its complicated...
Kimmerosaurus
Skull of Kimmerosaurus. From Brown (1981).
Kimmerosaurus is a poorly known cryptoclidid plesiosaur known only from skull and neck material (Brown 1981, Brown et al. 1986). It differs from other plesiosaurs in the large number of needle-like teeth in its jaws, and in the form of its teeth, which are completely smooth and lack the longitidinal ridges present in other plesiosaurs. Brown et al. (1986) compared...
