The pterosaurs of the Cretaceous Kem Kem Group of Morocco

Abstract The pterosaur assemblage of the mid-Cretaceous Kem Group Morocco is reviewed. This analysis examines their taxonomy, palaeoecology and palaeobiology with comments on taphonomy. New material permits rediagnosis azhdarchoids Alanqa saharica Afrotapejara zouhrii . Several specimens are reported that do not fit within paradigms previously named taxa. They represent three distinct jaw morphotypes, but assigned to new taxa here. highly diverse, including four tooth-bearing Ornithocheiridae five additional morphotypes Azhdarchoidea. most diverse for any pterosaur-bearing fluvial deposit one assemblage. heavily biased in terms preservation an as yet unexplained high abundance fragments. We highlight importance fragmentary studies.
