In Depth

       The original‭ ‬2012‭ ‬paper of the plesiosaur Spitrasaurus included the description of not one but two species for the genus.‭ ‬The type species,‭ ‬S.‭ ‬wensaasi‭ (‬PMO‭ ‬219‭ ‬718‭) ‬is described from sixty articulated cervical vertebrae believed to have come from a juvenile individual.‭ ‬S.‭ ‬larseni‭ (‬SVB‭ ‬1450‭) ‬is also known from cervical vertebrae,‭ ‬though not as well‭ ‬preserved as those of the type species,‭ ‬though S.‭ ‬larseni also has partial skull remains attributed to it.

       The genus name Spitrasaurus means‭ ‘‬Spitra lizard‭’ ‬and is based upon a portmanteau formed from Spitsbergen Travel.
