New insights into the origins and radiation of the mid-Palaeozoic Gondwanan stem tetrapods

ABSTRACT The earliest tetrapodomorph fishes appear in Chinese deposits of Early Devonian age, and by the Middle Devonian they were widespread globally. Evidence for the earliest digitated tetrapods comes from largely uncontested Middle Devonian trackways and Late Devonian body fossils. The East Gond...
