A primitive, extinct bird from the Jurassic period: Archeopteryx is the name of a specific genus of feathered dinosaur that is a transitional fossil between non-avian dinosaurs and modern birds. It is characterized by having teeth, a long bony tail, and wings with claws, alongside feathers and hollow bones.
Archeopteryx is used as a proper noun to refer to this specific genus. It is a technical term primarily used in paleontology, evolutionary biology, and related scientific discussions. - It is typically treated as a singular noun (e.g., an Archeopteryx, the Archeopteryx). - The plural form is Archeopteryges or, more commonly in general writing, Archeopteryxes.

- In Evolutionary Discourse: The term is often used as a key example of a "missing link" or transitional form. For example:
- In Taxonomic Discussion: It is used when discussing the classification of early birds and theropod dinosaurs. For example:
- Archaeopteryx (n): An alternative, equally common spelling of the same genus name.
- Archaeopterygidae (n): The family name that includes the genus .
- Urvogel (n): A German-derived term meaning "first bird" or "original bird," sometimes used synonymously with in historical scientific literature.
The word Archeopteryx refers specifically to one genus. It should not be used as a general term for all early birds or feathered dinosaurs, as many other distinct genera (e.g., Anchiornis, Xiaotingia) are now known. Its significance lies in its specific combination of ancestral (reptilian) and derived (avian) traits.
- extinct primitive toothed bird of the Jurassic period having a long feathered tail and hollow bones; usually considered the most primitive of all birds
