Rare Cretaceous Azhdarchid Pterosaur Limb Bone...

Scientific name: Unidentified Azhdarchid Pterosaur limb bone - Potencial Ulna Location: Taouz, Errachidia Province, South Morocco Geological Formation: Ifezouane Fm - Red Sandstone Beds Age: Upper Cretaceous, Cenomanian stage ( 96 million years) Size: 17,7 cm REF.: #J1011 DESCRIPTION: Observations: Azhdarchidae pterosaur family – Possible Ulna This fossil bone is tentatively attributed to a pterosaur belonging to the family Azhdarchidae. Based on its overall morphology, the specimen appears to represent an ulna. The bone is relatively well preserved; however, part of the distal epiphysis has been reconstructed. Due to this reconstruction and the absence of certain original anatomical features, a definitive identification of the skeletal element cannot be established with complete certainty. Nevertheless, its morphological characteristics strongly suggest that the specimen belongs to a pterosaur of the family Azhdarchidae. Its morphology resembles very much that of the Azhdarchid pterosaurs. Two genus of Azhdarchid pterosaurs have been described from the Upper Cretaceous (Cenomanian stage) of South Morocco. One of them, the genus Alanqa and the other the genus Xericeps, along few others. This specimen is something unique and worthy of study and comparison to similar remains already published. High scientific value. All of our fossils come with a Certificate of Authenticity. Every week, the issued Certificates of Authenticity are updated in our database verification system on our website.
