   Many people love their backyard birds, but some of us may not realize that those feathery friends are also literally dinosaurs, in a biologically accurate sense of that word.

3. (loosely, informal, proscribed) Any extinct reptile, not necessarily belonging to Dinosauria, that existed between about 230 million and 65 million years ago, as well as the stem-mammal Dimetrodon.

   • 1975, Frederick P. Brooks Jr., The Mythical Man-Month, published 1995:

     [The OS/360 linkage editor] is the culmination of years of development of static overlay technique. Yet it is also the last and finest of the dinosaurs, for it belongs to a system in which multiprogramming is the normal mode and dynamic core allocation the basic assumption.

   • 1999, Ron Harbin, Aaron Barker, Anthony L. Smith, “What About Now”, performed by Lonestar:

     The sign in the window said for sale or trade on the last remaining dinosaur Detroit made.

   I couldn't believe it when I saw the equipment that they were still using. Those machines were all dinosaurs, but they were busily cranking out production.

• Many animals commonly described as dinosaurs do not belong to Dinosauria, and are not true dinosaurs. These include pterosaurs, ichthyosaurs and plesiosaurs. Describing these as dinosaurs is frowned upon in scientific writing but persists in the media and in everyday speech.

• Conversely, not all members of Dinosauria became extinct in the Cretaceous–Paleogene extinction event. Those that survived were the ancestors of modern birds, which therefore also belong to Dinosauria. However, birds are not usually described as dinosaurs, except in some popular science and technical writing.
