"Mya" is an abbreviation for "millions of years ago." So "Dinosaurs lived 145 - 130 mya" means that they lived from 145 to 130 million years ago. However, although dinosaurs lived during that time, they first evolved 220 mya and the non avian dinosaur died out 65.5 mya. Avian dinosaurs (birds), still exist to the present day.
