Is There Evidence for Dark Matter Killing the Dinosaurs?

There's a theory that dark matter might coalesce into sort of like a disc. Like a big dark frisbee? Yeah. And when the sun passes through this dark matter disc, maybe it's the dark matter that's tugging on the things in the outer solar system and then knocking them in towards our safe little garden. Is there any evidence for this? You know, this is just a fun speculative theory. We don't have any direct evidence of the dark matter frisbee existing at all.
