Abstract The Fezouata Biota (Morocco) is a Burgess Shale-type (BST) assemblage that provides a wealth of information on Early Ordovician ecosystems. Much work has been done to compare the preservation of the Fezouata Biota to other BSTs. However, stu

Early developmental stages of a Lower Ordovician marrellid from Morocco suggest simple ontogenetic niche differentiation in early euarthropods

Early developmental stages of euarthropods are exceptionally rare in the fossil record. This hampers our understanding of the biology, phylogeny, and development of this extremely diverse metazoan group. Herein, we use classical paleontological metho

Radiodont frontal appendages from the Fezouata Biota (Morocco) reveal high diversity and ecological adaptations to suspension-feeding during the Early Ordovician

Autor: Gaëtan J.-M. Potin, Pierre Gueriau, Allison C. Daley

Publikováno v: Frontiers in Ecology and Evolution, Vol 11 (2023)

IntroductionThe Early Ordovician Fezouata Shale Formation (485–475Ma, Morocco) is a critical source of evidence for the unfolding Great Ordovician Biodiversification Event (GOBE), the largest radiation in animal diversity during the Paleozoic. The

The significance of Anomalocaris and other Radiodonta for understanding paleoecology and evolution during the Cambrian explosion

Autor: Gaëtan J.-M. Potin, Allison C. Daley

Publikováno v: Frontiers in Earth Science, Vol 11 (2023)

One of the most widespread and diverse animal groups of the Cambrian Explosion is a clade of stem lineage arthropods known as Radiodonta, which lived exclusively in the early Paleozoic. First reported in 1892 with Anomalocaris canadensis, radiodonts

Dwarf planet (1) Ceres surface bluing due to high porosity resulting from sublimation

Autor: Stefan E. Schröder, Olivier Poch, Marco Ferrari, Simone De Angelis, Robin Sultana, Sandra M. Potin, Pierre Beck, Maria Cristina De Sanctis, Bernard Schmitt

Publikováno v: Nature Communications, Vol 12, Iss 1, Pp 1-9 (2021)

The origin of blue ejecta around the fresh craters of dwarf planet Ceres is unknown. Here, the authors show that the blue color results from high porosity of the surface, induced by sublimation of ice-phyllosilicate mixture produced by impacts.

Samples of the carbonaceous asteroid Ryugu were brought to Earth by the Hayabusa2 spacecraft. We analyzed 17 Ryugu samples measuring 1 to 8 millimeters. Carbon dioxide–bearing water inclusions are present within a pyrrhotite crystal, indicating tha
