Abstract
A new ornithocheirid pterosaur, Akharhynchus martilli gen. et. sp. nov. from the Ifezouane Formation, Kem Kem Group of Morocco is described, based on a well-preserved anterior rostrum fragment. It is assigned to a new genus based on one autapomorphy and a unique combination of synapomorphies, including the following: the medial rims of the first alveoli pair contact each other and the first alveoli pair are 50% smaller than the second alveoli pair. Comparative anatomy and a phylogenetic analysis demonstrate that Akharhynchus has affinities with Tropeognathus within Tropeognathinae.
期刊介绍：
Cretaceous Research provides a forum for the rapid publication of research on all aspects of the Cretaceous Period, including its boundaries with the Jurassic and Palaeogene. Authoritative papers reporting detailed investigations of Cretaceous stratigraphy and palaeontology, studies of regional geology, and reviews of recently published books are complemented by short communications of significant new findings.
Papers submitted to Cretaceous Research should place the research in a broad context, with emphasis placed towards our better understanding of the Cretaceous, that are therefore of interest to the diverse, international readership of the journal. Full length papers that focus solely on a local theme or area will not be accepted for publication; authors of short communications are encouraged to discuss how their findings are of relevance to the Cretaceous on a broad scale.
Research Areas include:
• Regional geology
• Stratigraphy and palaeontology
• Palaeobiology
• Palaeobiogeography
• Palaeoceanography
• Palaeoclimatology
• Evolutionary Palaeoecology
• Geochronology
• Global events.
