Name: Makhaira ‭(‬named after a type of Ancient greek sword/large knife,‭ ‬with a backwards curving blade‭)‬.
Phonetic: Mak-hye-rah.
Named By: V.‭ ‬Fischer,‭ ‬M.‭ ‬S.‭ ‬Arkhangelsky,‭ ‬I.‭ ‬M.‭ ‬Stenshin,‭ ‬G.‭ ‬N.‭ ‬Uspensky,‭ ‬N.‭ ‬G.‭ ‬Zverkov‭ & ‬R.‭ ‬B.‭ ‬J.‭ ‬Benson‭ ‬-‭ ‬2015.
Classification: Chordata,‭ ‬Reptilia,‭ ‬Sauropterygia,‭ ‬Plesiosauria,‭ ‬Pliosauridae,‭ ‬Brachaucheninae‭?
Species: M.‭ ‬rossica‭ (‬type‭)‬.
Diet: Carnivore/Piscivore.
Size: Uncertain due to lack of remains,‭ ‬but very roughly estimated to be about‭ ‬5‭ ‬meters long.
Known locations: Russia,‭ ‬Ulyanovsk Oblast.
Time period: Hauterivian of the Cretaceous.
Fossil representation: Tips of upper and lower jaws,‭ ‬as well as partial dorsal‭ (‬back‭) ‬vertebrae and partial pelvic bones.

       Makhaira is a genus of pliosaur that lived in waters that once submerged parts of Russia during the early Cretaceous.‭ ‬Due to lack of fossil material,‭ ‬little is known about the overall details of Makhaira.‭ ‬But these remains seem to have come from a small to medium sized pliosaur.‭ ‬The known teeth of Makhaira seem to suggest that Makhaira was more of a generalist,‭ ‬capable of hunting moderately sized prey of all types,‭ ‬without overly specialising on any one specific type of creature.
       Makhaira has in the past been cautiously identified as a brachauchenine pliosaur,‭ ‬though overall lack of fossils have made this assessment uncertain.‭ ‬However,‭ ‬in‭ ‬2017‭ ‬an additional genus of brachauchenine pliosaur named Luskhan was described from fossils‭ ‬recovered from the same region of Russia that the Makhaira type fossils were recovered from.‭
