The family Cryptoclididae contains a variety of moderately sized long-necked plesiosaurs. Synapomorphies (shared unique characters) for this group include a narrow vertical jugal bar, an enlarged orbit, and a deeply excavated ventral cheek margin (Brown and Cruickshank 1994).

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.
