...-preserved macrofossil plant remains of Archaeopteris , Rhacophyton , cormose lycopsids , Gillespiea , and cupulate and acupulate gymnosperms. Detailed anatomical preservation of the charcoal combined with its paleoecological setting suggests that in this landscape, mostly Rhacophyton burned, perhaps...

Figure 1. Middle and Late Devonian timescale. Phytogeographic analyses of the following zones (Banks 1980 ) are presented here: the middle–late Givetian Svalbardia zone 5; the late Famennian lower Rhacophyton zone 7a; and the Strunian upper Rhacophyton or Cyclostigma–seudobornia zone 7b.

The specificity of the fires, the distribution profile of the plant remains deposited in the pond, and additional taphonomic evidence all support a model of niche partitioning of the Late Devonian landscape by plants at a high taxonomic level. At Red Hill...

First mats of only seed plants are observed, then monotypic Rhacophyton (early fern) layers and, finally, a diverse allochtonous assemblage. The successions present in Belgium, at the Langlier quarry, are roughly similarly organized ( Thorez...
