摘要
Mawsoniids are a lineage of extinct fresh/brackish water coelacanth fishes, common in Cretaceous Godwanan deposits of South America, North and West Africa and Madagascar. Here we formally describe mawsoniid remains from the fluvio-lacustrine Missao Velha Formation (Lower Cretaceous) of the Araripe Basin, North-East Brazil. The examples from the Missao Velha Formation are here described as Mawsonia cf. gigas, based mainly on elements of the lower jaw and opercular series. The occurrence of M. cf. gigas in the Missao Velha Formation expands the stratigraphic and geographical ranges of the type species. (C) 2016 Elsevier Ltd. All rights reserved.
