In Depth

       Related to the mosasaurs,‭ ‬the exact classification of Dolichosaurus is a little uncertain with‭ ‬its exact closeness to the Mosasauridae a little uncertain.‭ ‬Dolichosaurus is noted for having‭ ‬a long thin build and is speculated to have been a weak swimmer.‭ ‬This in turn has led to past speculation that it may have been semi aquatic,‭ ‬occasionally returning to the land like the much earlier nothosaurs of the Triassic.
