Genus Protoavis is a prehistoric bird that lived in the Late Triassic period. The term "Protoavis" comes from the Greek word meaning "first bird." Some synonyms for this genus include "Pterodactylus Protoavis," "Protoavis texensis," and "Protoavis sanjuanensis." These names all refer to different species of the Protoavis genus that were discovered in different regions of the world. Protoavis is considered an important discovery in the study of avian evolution, as it provides evidence that birds may have evolved from an earlier group of reptiles. Though Protoavis is not considered a direct ancestor of present-day birds, its discovery sheds light on the evolution of flight in animals.
