“…Besides, the La Mina section consists of a 170 m thick sequence of interlayered sandstones, siltstones, shales, and coals considered as belonging to the Ambo Group ( Figure 1D). The detailed studies of the palynological content have pointed to a late Visean age for this unit in other areas of Peru (Azcuy & di Pasquo, 2005, 2006.…”

-Paulophyton has the appearance of an Early or Middle Devonian plant but is found in the Carboniferous. This report from Peru expands our knowledge of its unusual biogeographic distribution (Peru, Brazil, Argentina, Bolivia, and Germany) that includes the southern temperate Paracas realm (Gondwana) and the Carboniferous tropics (Euramerican Realm). Stratigraphically Paulophyton is known from the late Tournaisian (Mississippian) to the middle of the Pennsylvanian. It is an uncommon but apparently widespread plant characterized by leafl ess, thin axes with small, terminal sporangia. It is found mostly as very small fragments, a fact that makes it easy to overlook. Paulophyton may be the representative of a plant group that has otherwise not yet been recognized in the Carboniferous. Key words:Paulophyton, late Visean, Paracas Realm, Ambo Group, La Mina Section, Peru.RESUMO -Paulophyton é uma planta com aparência de outras encontradas no Devoniano Inferior e Médio, mas é registrada no Carbonífero. Este registro no Peru expande nosso conhecimento sobre a sua incomum distribuição biogeográfi ca (Peru, Brasil, Argentina, Bolívia e Alemanha) que inclui o reino temperado do sul (Paracas, parte do Gondwana) e os trópicos carboníferos (Reino Euroamericano). Estratigrafi camente, Paulophyton é conhecido desde o fi nal do Tournaisiano (Mississipiano) até o Pensilvaniano médio. Esta exótica, mas aparentemente bem distribuída planta é caracterizada pelos seus eixos fi nos e áfi los que suportam pequenos esporângios terminais. Ela é encontrada normalmente na forma de pequeníssimos fragmentos, um fato que faz com que seja facilmente negligenciada nas associações. Paulophyton pode ser o representante de um grupo vegetal que ainda não foi reconhecido no Carbonífero.

a b s t r a c tThe Middle Member of the Zorritas Formation in the Antofagasta Region of northern Chile, yielded terrestrial and marine palynomorph assemblages which span the Devonian/Carboniferous boundary. The assemblages show a clear predominance of terrestrial palynomorphs with 70 miospore species, 18 marine phytoplankton species, two non-marine algae and one chitinozoan species, all coming from 15 productive levels. Palynomorphs are poorly preserved and most of them are reworked. Three palynological associations are recognized based on miospores. These are assigned to the TournaisianeVisean, Tournaisian and probable latest Famennian. Age assignments are discussed in the frame of the spore zonal schemes established for Euramerica and western Gondwana. The stratigraphical distribution of spores allows the identification of the probable position of the Devonian/Carboniferous boundary within the Zorritas Formation. This system boundary is proposed for the first time in Palaeozoic sedimentary rocks of northern Chile. The presence of Gondwanan typical miospore species indicates affinities with this palaeocontinent even though the Tournaisian and TournaisianeVisean miospore associations support the cosmopolitanism already suggested for the early Carboniferous flora. The significant number of reworked palynomorphs together with the sedimentological analysis of the studied sections, suggest that these deposits were severely impacted by the climatic change and major sea level fluctuations. Similar conditions were recorded in coeval western Gondwana basins.Ó 2016, China University of Geosciences (Beijing) and Peking University. Production and hosting by Elsevier B.V.
