The presence of this species in Thailand may provide an explanation for the distribution of fossil gharials that appears disjunct, covering Pakistan and Java but not the connecting areas. The fossils suggest that gharials may have dispersed from Indo-Pakistan to Indonesia through Thailand without having to resort to marine routes.[3]
