Vegetation function and distribution have changed over deep time as plant groups evolved and introduced new adaptations to their environments (plant traits). The succession of the dominant plant groups (i.e. sporophytes, gymnosperms, angiosperms) is usually assumed to have coincided with changing plant impacts on biogeochemical cycles, such as rate...

The first occurrence of the fossil-genus Phyllotheca (Equisetales) from the Carboniferous of Portugal is documented and its palaeobiogeographical, systematic and evolutionary significance is assessed. In this paper, we described this new equisetalean fossil as new species, Phyllotheca douroensis sp. nov., found in the Douro Carboniferous Basin (low...

Plant adaptations to environmental and climatic changes in Pangaean intramontane basins are poorly understood. Here, we document a previously unknown primitive gymnosperm species, Lesleya ceriacoi sp. nov., from the Douro Carboniferous Basin (DCB; lower Gzhelian, Upper Pennsylvanian; NW Portugal) of the Variscan Iberian Massif (Iberia). This new sp...

This presentation is on casting techniques in paleontology with a focus on latex casts and Paleobotany.

[EN] In this paper, we present the history of latex in Paleontology and its role in the field today. We discuss the methodology and advantages of latex fossil moulds, while also presenting examples of moulds of compressions/impressions of plant fossils. Latex rubber has been used to create moulds of fossils since the first half of the 20th century...
