Lungfishes (Dipnoi, Sarcopterygii) initially radiated in the Early Devonian, and reached the apogee of their diversity during this period, especially with regard to their dentitions. Following the end-Devonian extinction, most of this diversity was lost and remained low throughout the Carboniferous and the rest of the Palaeozoic, mainly represented...

Marokko ist weltbekannt für dessen einzigartigen Fossilreichtum. Ein Großteil der Geschichte des marinen Lebens auf der Erde der letzten 450 Millionen Jahre ist in den Gesteinen des Landes überliefert. Von Fischen und Korallen bis zu Dinosauriern und Walen bieten die Fundstellen Marokkos ein Fenster in die Vergangenheit unseres Planeten. Einzigarti...

Lungfishes are an extant clade of lobe-finned fishes (Sarcopterygii) that evolved in the earliest Devonian, and reached a peak of diversity during this period (Ahlberg et al. 2006). Following the end-Devonian mass extinction, it was thought that lungfishes had suffered a great loss in diversity, with very few taxa surviving into the Early Carbonife...

The origin of vertebrate paired appendages is one of the most investigated and debated examples of evolutionary novelty1–7. Paired appendages are widely considered as key innovations that enabled new opportunities for controlled swimming and gill ventilation and were prerequisites for the eventual transition from water to land. The past 150 years o...
