What caused the extinction of the dinosaurs?

[Whale]

The most widely accepted theory for the extinction of the dinosaurs is the impact of a massive asteroid or comet hitting the Earth around 66 million years ago. The impact caused widespread devastation, including fires, tsunamis, and a cloud of dust and debris that blocked out the sun, leading to a dramatic drop in temperature and an inability of plants to photosynthesize. This catastrophic event is believed to have caused the mass extinction of the dinosaurs, as well as many other species.

Moving this promotional topic to the author section (mostly because dinosaurs interest me and I am feeling generous this morning).

But this is the one and only "pass" for the OP, and ANY further promotional topics by them that are NOT in the author and promotional section (since according to group rules, authors are ONLy allowed to promote their own work in the author/promotional section and nowhere else) will immediately be deleted by one of the moderators and without explanation.

And I will say that I am getting increasingly annoyed how often authors, publishers etc. do not bother checking the group rules before posting.
