A decidedly moot point. Several hundred thousand years is also a
possibility.

And a tsunami event would not explain why
late Mesozoic sea reptiles as well as pterosaurs would also be wiped out.

The marine "reptiles" certainly; the pterosaurs would only need to be
kept on the wing for a generation or so to be rendered extinct (no one has
seriously suggested that they lay, incubate, hatch on the wing).

Unless of course you believe that a few of the sea beasties are still hiding
out in a long thin but very deep lake in Scotland! grin

Two such lakes (several hundred miles apart).
My aunt swears blind that she's seen one of the beasties from her
garden abutting Loch Ness. Knowing my aunt, I take this as strong evidence of
the non-existance of Nessie.
