No.

Oh you are correct Androcles it was 65 miljon years ago
But the the Triassic–Jurassic extinction event marks the boundary
between the Triassic and Jurassic periods, 199.6 million years ago,
and is one of the major extinction events.

I do not know but i see the possibility for some doubts in carbon
dating, and also when it comes to put dates on events within
astronomy. I find it reasonably to beleive that Sirius B was cause to
the Triassic-Jurassic extinction.

Whoopee for you. yawn
Now prove it.
I find it reasonably to believe that bright green flying elephants lay their
eggs in black holes but I do not know and I can't prove it... and you
are not really interested. Let's prove Santa Claus comes down chimneys
instead, we can both believe that one.
