Of course, but I would like add some points.
All Birds Are Dinosaurs:Birds are classified as avian dinosaurs, meaning they are a part of the dinosaur clade. Specifically, they belong to the group Theropoda, which includes well-known non-avian dinosaurs like Tyrannosaurus rex and Velociraptor.Not All Dinosaurs Are/Were Birds:Dinosaurs encompass a broad group of reptiles that includes both avian and non-avian dinosaurs. Non-avian dinosaurs include all the dinosaurs that are not part of the lineage that gave rise to modern birds.Pterodactyls Are Neither Birds Nor Dinosaurs:Pterodactyls, often used to refer to pterosaurs, are flying reptiles that lived during the age of dinosaurs but are not classified as dinosaurs. Pterosaurs belong to a distinct group called Pterosauria, separate from the Dinosauria clade. They were the first vertebrates known to have evolved powered flight.
No, birds are not dinosaurs. Birds are descended from ancestral dinosaurs, which in turn are descended from archsaurs, etc. If you go back far enough in time, the first known life forms are microscopic organisms. You don't say that dinosaurs, birds, etc... are microbes. There is a big difference between being a dinosaur or descended from a dinosaur. Birds have evolved as their own class Aves (although a small group of scientists classify birds as a subclass). Birds are birds.
