Science theory: does it make sense?

So, there are 5 ocean zones. Sunlight zone, twilight zone, midnight zone, abyss, and the trenches. The abyss has never ever and never will see sunlight. Supposedly the dinosaurs became extinct because of a meteor that wiped the face of the Earth. The abyss would not have been affected. So, technically couldn't prehistoric species still be living down there? They would be adapted to the pressure. For all we know, there could be lochness-type monsters living down there. DOES THIS MAKE SENSE OR AM I CRAZY????

The deep ocean is affected by the surface seawater. Oxygen gets to the ocean bottom because surface water that is oxygenated sinks to the bottom. Otherwise nothing would be able to live there at all. The deep sea is mostly 3-4 km in depth. The asteroid that created the Chicxulub crater was 10 km across... three times as large as the ocean is deep.
Sometimes the oceanic conveyor belt is weakened and oxygen cannot get to the deep seafloor. It is unlikely that deep-sea creatures have survived through those times.

It makes a little sense.
Corollary: you are a little crazy.

What do you mean by prehistoric?
Many species exist today that already existed prior to Homo sapiens.
You don't have to go to the deep ocean to find them.

Have you heard the stories about the coelacanth?

Deep oceans are less impacted by asteroid collisions but that doesn't mean that deep-sea dinosaurs survived to this day. There are other evolutionary pressures that come to bear.

As for unknown deep-sea creatures, I'll believe them when I see them. Until then, it's all fiction.
