 Based only on the size of the skull, the full body size of "Loxomma" is approximated to be 14 feet long, although it is hard to tell definitively without the presence of any post-cranial bones.They lived between the water and the land feeding on live fish as is evident in the shape of their jaw hinge and their two-edged teeth.Because the nasal bones are paired and the nasal apertures are both anterior and pharyngeal, it is indicated that they did breathe air.
