In my own opinion , Though their extinction is a mystery . I think why dinosaurs became extinct on earth it's because of maybe geologic events , a big meteorite crashed into the earth that it changed the climate conditions so explicit that dinos could not withstand or survive the impact of meteorites. Some case would be a disease that dinos would be wiped out the entire population and food chain imbalance. There are some also theories if you have time you could research this from the internet.
