Abstract. A stem relative of dragon- and damselflies, Brunellopteron norradi 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 + CuA fusion, a CuA + CuP fusion, and a CuP + AA fusion, but it lacks the “extended” MP + Cu / CuA fusion and the “extended” (CuP / CuA + CuP) + AA fusion, the occurrence of which is typical of most Odonata, including Meganeura-like species. The occurrence of intercalary veins suggests that its closest relative might be Gallotypus oudardi Nel, Garrouste and Roques, 2008, from the Moscovian of northern France.

A new specimen of Batrachichnus salamandroides was recovered from a recently discovered fossil-bearingsite situated along the southern shore of Grand Lake, New Brunswick, among a diverse ichnofaunal assemblagefrom the Middle Pennsylvanian (upper Bolsovian; lower Moscovian), upper Minto Formation. The identity ofthe tracemaker of this ichnogenus is reinterpreted as a composite of various late Paleozoic tetrapod taxa, basedon similarities of the postcranial skeletons, notably that of the manus and pes, of both temnospondyls and some“microsaurs”. These results indicate that the tracemaker of the monospecific ichnogenus Batrachnichus is notlimited solely to a temnospondyl tracemaker, as previously interpreted, and that some “microsaurs” should alsobe considered among tracemaker candidates for this ichnotaxon.
