“…The fossil flora of the Battery Point Formation, studied ever since the mid‐19 th century (Dawson, 1859), has recently yielded a diversity of permineralized taxa that contribute to the understanding of early tracheophyte anatomy, phylogeny, and development (Bickner & Tomescu, 2019; Durieux et al ., 2021; Pfeiler & Tomescu, 2021; Toledo et al ., 2021; Tomescu & McQueen, 2022). Secondary growth, a major structural innovation in plants until recently thought to have evolved in the Middle Devonian, has been shown to have arisen much earlier (Gerrienne et al ., 2011) and has been documented in several plant types of the Gaspé flora that produced secondary xylem (Hoffman & Tomescu, 2013; Pfeiler & Tomescu, 2021; Toledo et al ., 2021).…”
