Perhaps a shared ancestor between the Leviathans? it is suggested that the reaper, Sea Dragon and Sea Emperor are genetically linked, with the Sea Emperor being an older genus than the other two.

But the Carar thing is false - it was already a fossil before the Precursors set up their base to study it and the Carar.

Ancestor, yes - carar, no...
