Background In extant ecosystems, complex networks of ecological interactions between organisms can be readily studied. In contrast, understanding of such interactions in ecosystems of the geologic past is incomplete. Specifically, in past terrestrial

We discuss a recent assessment by Dörken et al. (2021) regarding the affinities of the Eocene fossil species Huncocladus laubenfelsii from Laguna del Hunco (Patagonia, Argentina). We originally (Andruchow-Colombo et al., 2019) assigned this species

Premise of research. Despite the ecological significance of arbuscular mycorrhizae in modern terrestrial ecosystems, knowledge about their evolution based on the fossil record is still scarce, especially concerning the case of root nodules harboring

Heinrichsiella patagonica gen. et sp. nov.: A Permineralized Acrocarpous Moss from the Jurassic of Patagonia

Autor: Diego Martin Guido, Adolfina Savoretti, Ignacio H. Escapa, Alexander C. Bippus, Juan Garcia-Massini

Publikováno v: International Journal of Plant Sciences. 180:882-891

Premise of research. Today, mosses are the second most speciose lineage of land plants and are important components of many ecosystems. However, in spite of their diversity and ecological importance in the modern biota, mosses are rare in the fossil
