Short summary
A specimen of an extinct relative of damsel- and dragonflies was discovered from ca. 310-million-years-old strata from New Brunswick (Canada). It is composed of an incomplete hindwing belonging to a new species whose wingspan was about 35 cm. Despite its incompleteness, it composes a useful addition to our knowledge of the early evolution of the group, owing to its unique combination of traits.
