Agathoxylon (also known by the synonyms Dadoxylon and Araucarioxylon[3]) is a form genus of fossil wood, including massive tree trunks. Although identified from the late Palaeozoic to the end of the Mesozoic,[4]Agathoxylon is common from the Carboniferous to Triassic.[5]Agathoxylon represents the wood of multiple conifer groups, including both Araucariaceae[6] and Cheirolepidiaceae,[7] with late Paleozoic and Triassic forms possibly representing other conifers or other seed plant groups like "pteridosperms".[8]
