Letter: Arachnophobia and the dinosaurs

Sir: To your seven theories about extinction of the dinosaurs ("The day the dinosaurs died", 18 February), may I add an eighth?

The later dinosaurs had to share the world with the early ancestors of today's mammals - small and agile creatures - scurrying round their feet. Bearing in mind the attitude of many people to our present domestic livestock, mice and spiders (small and agile), I think the poor old reptiles simply died of fright.
