Abstract The Ordovician of Scandinavia (ie Denmark, Norway and Sweden) has been
investigated for over two centuries and, through time, various chronostratigraphic schemes …

Early Palaeozoic sites with soft-tissue preservation are predominantly found in Cambrian
rocks and tend to capture past tropical and temperate ecosystems. In this study, we describe …

Abstract The Early Ordovician is a key interval for our understanding of the evolution of life
on Earth as it lays at the transition between the Cambrian Explosion and the Ordovician …

Trilobites are a major component of both biomineralized and soft-bodied assemblages of the
Fezouata Biota, central Anti-Atlas, Morocco. Trilobite taxa of the Fezouata Shale …

Abstract The Cambrian–lower Ordovician volcanic units of the South Armorican and Occitan
domains are analysed in a tectonostratigraphic survey of the French Variscan Belt. The …

A Cambro-Ordovician palaeogeographical restoration of the southwestern European margin
of Gondwana is proposed based on the relative positions of Variscan tectonostratigraphic …

Echinoderms are one of the major components of benthic faunas in the Lower Ordovician
sequence near Zagora, central Anti-Atlas, Morocco. The Fezouata Shale (Tremadocian–late …

The Fezouata Lagerstätte, discovered in the Lower Ordovician rocks of Morocco, is a
Konservat-Lagerstätte of prime scientific importance. It provides access not only to the …

Stylophorans (cornutes, mitrates) represent one of the most diverse classes of Cambro-
Ordovician echinoderms. They were free-living, benthic, non-radiate forms, closely related to …

Ecology and tempo of the Lower Palaeozoic radiation of echinoderms are discussed in this
paper based on comparison of the diversity patterns observed in Cambro–Ordovician …
