Do you supposed the gently "drifting" continents suddenly decided to
create rifts between them large enough to swollow that much water?  Or
was it continental "rip", caused by moving plates slaming into each
other during a crust shift, some 3,600 years ago.

  Earth in Upheaval, Dropped Ocean Level
    R.A. Daly observed that in a great many places all around
    the world there is a uniform emergence of the shore line of
    18 to 20 feet.  In the southwest Pacific, on the islands
    belonging to the Samoan group but spread over two hundred
    miles, the same emergence is evident.  Nearly halfway around
    the world, at St. Helena in the South Atlantic, the lava is
    punctuated by dry sea caves, the floors of which are covered
    with water-worn pebbles, now dusty because untouched by
    the surf.  The emergence there is also 20 feet.  At the Cape
    of Good Hope caves and beaches also prove recent and
    sensibly uniform emergence to the extent of about 20 feet.

    Marine terraces, indicating similar emergence, are found
    along the Atlantic coast from New York to the Gulf of
    Mexico;  for at least 1,000 miles along the coast of eastern
    Australia;  along the coasts of Brazil, southwest Africa, and
    many islands in the Pacific, Atlantic, and Indian Oceans.
    The emergence is recent as well as of the same order of
    magnitude, (20 feet).  Judging from the condition of beaches,
    terraces, and caves, the emergence seems to have been
    simultaneous on every shore.

    In [Daly's] opinion the cause lies in the sinking of the
    level of all seas on the globe.  Alternatively, Daly thinks it
    could have resulted from a deepening of the oceans or
    from an increase in their areas.  Of special interest is the
    time of the change.  Daly estimated the sudden drop of
    oceanic level to (have occurred) some 3,000 to 4,000 years
    ago.
