Investigation and Research Status of Devonian in Morocco,NW Africa
The Moroccan Devonian is renowned in the fields of geology,especially in paleontology,for its abundant and well-preserved fossils,which have yielded trilobites,cephalopods,corals,brachiopods,conodonts,fishes,and plants.These fossils provide valuable evidence for clarifying stratigraphic sequences,ascertaining fossil communities,paleoenvironments and geological events.Moreover,due to Morocco's unique paleogeographic location in the Devonian,the identification of rock associations,biotic provinces and their spatiotemporal distribution contributes to the reconstruction of the ocean systems between Gondwana and Laurussia.In this article it reviews the history of Morocco geological surveys and discusses the three main stages of Morocco Devonian research.In recent years,interdisciplinary study and cross-regional cooperation have emerged as the main development trends.Significant new discoveries and insights have been made in the fields of paleontology,paleogeography,and paleoclimatology by leveraging the abundant fossil resources in Morocco.Making full use of this treasure trove of fossils will help to better understand the evolutionary history of the earth and deal with today's biodiversity crisis and environmental problems.
