So whether mekosuchines owe their distribution to dispersal or vicariance, we can be quite confident that they inhabited islands in the south-west Pacific where their presence has yet to confirmed.

Ingeniously fostering variance,
With tectonic drift
And mountains’ uplift
Deployed in the cause of vicariance.
