Abstract The Fezouata Biota in Morocco is the only Lower Ordovician Lagerstätte yielding a
biologically diverse assemblage in a fully marine environment, whilst also containing …

Introduction The Early Ordovician Fezouata Shale Formation (485–475Ma, Morocco) is a
critical source of evidence for the unfolding Great Ordovician Biodiversification Event …

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 Fezouata Biota (Morocco) is a unique Early Ordovician fossil assemblage. The
discovery of this biota revolutionized our understanding of Earth's early animal …

Understanding the functioning of extinct ecosystems is a complicated knot of ecological,
evolutionary, and preservational strands that must be untangled. For instance, anatomical …

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 …

Exceptional fossils preserve non-biomineralized tissues in the geological record and
provide crucial information on the evolution of life on Earth. Exceptionally preserved fossils …

Exoskeleton moulting is the process of shedding the old exoskeleton to enable growth,
development and repair, representing a crucial recurrent event in the life histories of all …

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 …

Abstract The Chengjiang Biota is the earliest Phanerozoic soft-bodied fossil assemblage
offering the most complete snapshot of Earth's initial diversification, the Cambrian Explosion …
