       Mesoleptos is a genus that shares several characteristics of snakes and primitive mosasauroids,‭ ‬however at the time of writing Mesoleptos is thought to be more likely a primitive mosasauroid.‭ ‬If correct then this would place Mesoleptos closer to actual monitor lizards than snakes,‭ ‬given that later discoveries with mosasaurs indicate a monitor lizard lineage.
       Mesoleptos shows several features that would have supported a lifestyle that saw it regularly entering into and swimming in water.‭ ‬These include a laterally compressed tail as well as a reduction in limb size,‭ ‬though Mesoleptos may well likely ventured out of the water when resting.‭ ‬Mesoleptos would have probably been a hunter of small aquatic organisms.
