Trilobite faunal dynamics on the Devonian continental shelves of the Ardenne Massif and Boulonnais (France, Belgium)
(Polish Academy of Sciences. Institute of Paleobiology, 2015-11)
During the Devonian the sedimentation on the continental shelves of Ardenne Massif and Boulonnais has changed from a mixed siliciclastic-carbonate ramp (Eifelian), through a carbonate barrier reef (Givetian) and then to a ...
A marine connection between parnaíba and paraná basins during the eifelian/givetian transition: Review and new data
(2016-01-01)
A long-lived marine seaway between the Parnaíba and Paraná basins occurred during a global marine transgression between Brazilian intracratonic basins (except for the Solimões Basin) in the latest Eifelian/earliest Givetian ...
Sequence stratigraphy and taphonomic signatures of marine invertebrates: A Devonian (Pragian/Eifelian) example of the Paraná Basin, Brazil
(Brasil, 2012)
The latest Pragian to the early Eifelian succession of the Devonian of the eastern border of the Paraná Basin (Brazil) is approached integrating taphonomy and sequence stratigraphy, providing new insights to the analysis ...
Paleoecologic trends of Devonian Malvinokaffric fauna from the Paraná Basin as evidenced by trace fossils
(2021-08-01)
The Malvinokaffric Realm is an endemic paleogeographic region that inhabited Gondwanan high latitude seas during Early-Middle Devonian times. The causes for the collapse of this fauna are still debated but seem to be related ...
