Abstract
Abstract The Trout Valley Formation of Emsian–Eifelian age in northern Maine hosts evidence of early vascular plant communities interpreted as having colonized wetland, estuarine environments. To date, collections made under permits issued by the Baxter State Park Commission originate from outcrop along Trout Brook, its tributaries, and poorly exposed lithologies inside the woodlands. Construction of a new roadway in the Scientific Forest Management Area, oriented parallel to Trout Brook, unearthed pavement exposures in which new fossil assemblages were found. These were collected under a salvage and conservation effort. Plant megafossils, as well as new macroinvertebrates and ichnofossils, were recovered from sandy siltstone and siltstone lithofacies along a west-to-east transect along Wadleigh Mountain Road. Autochthonous plants fossils include erect axes of cf. Psilophyton forbesii and vertical rooting structures of unknown affinity. Parautochthonous and allochthonous plants include Pertica quadrifaria...
