It is impossible to fix the dinosaurs' extinction to a specific year for several reasons:
- There were no intelligent animals alive at the time of the dinosaurs, and so there were no calendars and no record keeping.
- Even though dinosaurs are thought to have become extinct due to a single cataclysmic event, the actual extinction process itself likely took place over several years, decades, or even centuries.
- Even if the extinction was confined to a single year, there is currently no means to date the extinction event that precisely.
The traditional answer is that all dinosaurs disappeared from the fossil record 65.5 million years ago at the end of the Cretaceous Period.
However the similarities in the morphology of birds and avian dinosaurs has lead to many scientists considering birds to be modern day dinosaurs. In this case they have not yet disappeared from the fossil record.
The extinction of the dinosaurs happened about 65 million years ago.
