Crow of Judgement

The modern scientific consensus regarding the origin of birds, based on reverse genetic engineering and examination of the fossil record, is that they are an evolved variant of dinosaur. This effectively means that while the dinosaurs we most commonly associate with the name went extinct, dinosaurs as a whole still exist in the form of birds, making birds literal living dinosaurs.

Additionally, if you want to get pedantic, this means that birds are technically a type of reptile.
