Pterosaurs

Research

  • Mazin & Pouech (2020) describe non-pterodactyloid pterosaur tracks from the ichnological site known as "the Pterosaur Beach of Crayssac" (Tithonian; south-western France), evaluate the implications of these tracks for the knowledge of the terrestrial capabilities of non-pterodactyloid pterosaurs, and name a new ichnogenus Rhamphichnus.[95]
  • A coleoid cephalopod specimen preserved with an associated tooth of a pterosaur (probably Rhamphorhynchus) is reported from the Upper Jurassic Altmühltal Formation (Germany) by Hoffmann et al. (2020), who evaluate the implications of this finding for the knowledge of feeding behaviours of Rhamphorhynchus.[96]
  • A well-preserved basihyal is reported for the first time in a pterosaur specimen (possibly belonging to the species Gladocephaloideus jingangshanensis) from the Lower Cretaceous Yixian Formation (China) by Jiang et al. (2020).[97]
  • Jacobs et al. (2020) describe new fossil material of pterosaurs from the Kem Kem Beds (Morocco), bringing the Kem Kem pterosaur fauna up to at least nine species (of which three are ornithocheirids), and confirming that toothed pterosaurs remained diverse during the mid-Cretaceous.[98]
  • Averianov (2020) reassesses the taxonomy of the Lonchodectidae, transferring the species "Lonchodraco" machaerorhynchus (including L. microdon and Pterodactylus oweni) to the genus Ikrandraco. [99]
  • New information on the anatomy of Dsungaripterus weii (especially on the palatal region), based on the study of new and previously collected specimens, is published by Chen et al. (2020).[100]
