This is when the dinosaurs went down and some think that that (or these) meteorite impacts may have been responsible.

No commercial intent in any of this but I do like to create maps and paintings as an escape from the easel. I have fourteen years experience doing this kind of thing but, to date, its been a huge losing proposition. Enjoy!
