In Depth

       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.‭
