| description | <p>A stem relative of dragon- and damselflies,
<i>Brunellopteron norradi</i> Béthoux, Deregnaucourt and Norrad gen. et sp. nov., is documented
based on a specimen found at Robertson Point (Grand Lake, New Brunswick,
Canada; Sunbury Creek Formation; early Moscovian, Pennsylvanian) and
preserving the basal half of a hindwing. A comparative analysis of the
evolution of wing venation in early odonates demonstrates that it belongs to
a still poorly documented subset of species. Specifically, it displays a
MP <span class="inline-formula">+</span> CuA fusion, a CuA <span class="inline-formula">+</span> CuP fusion, and a CuP <span class="inline-formula">+</span> AA fusion, but it lacks the
