Recently, researchers from McGill University identified a new dinosaur-era dragonfly fossil named Cordualadensa acorni from Alberta’s Dinosaur Provincial Park.
About Cordualadensa acorni
- It represents the first Mesozoic dragonfly fossil in Canada and fills a 30-million-year evolutionary gap in dragonfly history.

- The fossil led to the creation of a new family, Cordualadensidae, highlighting its unique anatomical features.
Features of Cordualadensa acorni
- Wingspan: Roughly the width of a human hand.
- Anatomy: The wing structure indicates adaptation for gliding flight, a feature common in migratory dragonflies today.

- First dinosaur-aged dragonfly fossil discovered in Canada.
- It is the first North American member of the dragonfly group Cavilabiata.
