ancient, primitive birds

Etymology
Etymology Information

'archaeornithes' originates from Greek, specifically the combining form 'archaeo-' from 'arkhaios' meaning 'ancient' and 'ornithes' from 'ornis/ornith-' meaning 'bird'.

Historical Evolution

'archaeornithes' was coined in modern scientific taxonomy (19th century onward) by combining the Greek roots 'archaeo-' and 'ornithes' to name early fossil birds such as 'Archaeopteryx'.

Meaning Changes

Initially, it meant 'ancient birds' in a general descriptive sense; over time its use has become more technical or sometimes considered obsolete/paraphyletic as avian phylogeny has been revised.
