Abstract

: The early Toarcian Jenkyns Event (~183 Ma) was characterized by a perturbation of the global carbon cycle, global warming, which at continental areas led to intensifi ed chemical weathering, enhanced soils erosion, and intensifi ed wildfi res. Warming and acid rain aff ected diversity and composition of land plant assemblages, caused a loss of forests and thereby impacted on trophic webs. The Jenkyns Event, triggered by volcanic activity of the Karoo-Ferrar Large Igneous Province, changed terrestrial ecosystems

期刊介绍： The journal is international and publishes original manuscripts in Spanish and, preferentially, British spelling English on all aspects of broad interest in palaeontology. Particularly, the SJP aims to communicate and promote palaeontological research to the global scientific community. Moreover, articles on new discoveries and approaches are especially welcome. Finally, studies of present-day material can be included if they have significant palaeontological relevance.
