Archaeopteryx caldecutti

Archaeopteryx caldecutti (ARE-key-op-TER-ix CALL-deh-cutty-i), nicknamed the First Bird Pokémon, is a species of bird in the Archaeopterygidae family. It is the only known species in the order, family and genus, making it monotypic. Its name is derived from the Ancient Greek word archaīos meaning ancient, and ptéryx, meaning feather or wing. It is named in honour of Émile Caldecutt.

This species was once thought to be extinct and thought to only exist via reviving fossils, however; this remains untrue. They were rediscovered by René Perry and Émile Caldecutt.
