The origin of gryposuchines is unclear. Earlier gavialids that were their probable ancestors are known from Africa and Asia. Traditionally, an African origin has been favored because gavialids would have been more likely to cross the [[Atlantic Ocean]] than the longer expanses of the [[Pacific Ocean]]. Moreover, warm equatorial currents run across the Atlantic from Africa to the Americas, assisting in travel. The presence ''Aktiogavialis'' in the Caribbean supports an Atlantic migration. Being the oldest known gryposuchine, ''Aktiogavialis'' was likely in the closest position to the time and location of the radiation.<ref name=V-JBS07/>
Gryposuchines as a whole largely disappeared in the [[Pliocene]], alongside several other [[Gavialidae|gavialid]] taxa, due to poorly understood factors, though possibly linked to climate changes of the period. However, the Late [[Pleistocene]] or [[Holocene]] aged ''[[Ikanogavialis|"Gavialis" papuensis]]'' from the [[Solomon Islands]] is a clear gryposuchine, separated from its closest relatives by a temporal barrier of at least 6 million years and a geographical barrier of at least 10,000
