This discovery marks the first occurrence of Burgess Shale-type faunas after the Middle Cambrian, and shows that their perceived absence from younger deposits is a taphonomic artifact rather than the result of

but our understanding of ecological changes during the Great Ordovician Biodiversification Event (GOBE) is currently limited by the paucity of Ordovician exceptionally preserved open-marine faunas. Here
as approximately 97% of discovered biotas represent tropical and temperate ecosystems within 65° north and south of the palaeoequator4. This pattern is particularly true for the Ordovician, where very few Lagerstätten are known from polar environments4. Among the most famous Ordovician Lagerstät...
A similar situation is also in the trilobite faunas of South China, but the graptolite M Fauna was already dominant at the beginning of Silurian (at least 2–3 Myr earlier than that of brachiopods and trilobites) (Chen et al., 2004a). The turnover of rugose coral faunas from ...
They preserve a diverse range of environments and faunas, preventing meaningful palaeoecological comparisons between regions. The only currently described Ordovician Burgess Shale-type fauna (diverse, open-marine soft-bodied assemblage preserved in fine sediments) is the Tremadocian-Floian Fezouata Biota...
Elements of these communities continued into the Early Ordovician at high latitude, but our understanding of ecological changes during the Great Ordovician Biodiversification Event (GOBE) is currently limited by the paucity of Ordovician exceptionally preserved open-marine faunas. Here we clarify the ...
It offers a unique opportunity to document the transition between the Cambrian and Palaeozoic evolutionary faunas. Recent fieldwork in the area north of Zagora has yielded critical new information on both the precise stratigraphic position of, and the palaeoenvironmental conditions associated with, the...
Exceptionally preserved soft-bodied faunas, belonging to the Fezouata and Tafilalt biotas, were recently discovered from the Early and Late Ordovician of Morocco. Both show that analogues of the Cambrian Burgess Shale (i.e. Fezouata) and terminal Neoproterozoic Ediacaran (Tafilalt) taphonomic windo...
