Spathagnathus
''Spathagnathus'' (meaning "spatula jaw") is a genus of ctenochasmatid pterosaur from the Late Jurassic Solnhofen Limestone of Germany. The type species, type and only species is ''Spathagnathus roeperi'', known from a single jawbone. It is the oldest known member of Gnathosaurinae, and the second pterosaur from the Solnhofen's Brunn quarry after the rhamphorhynchid ''Bellubrunnus''. The unique dental anatomy of the taxon is thought to indicate a diet of tough, hard-shelled prey items. Discovery and naming In 1993, Simone Kaulfuß, Maren Sendelbach and Andreas Heiner, students at the ''Schule für Präparationstechnische Assistenten'' in Bochum, in the chalk quarry of Brunn, Upper Palatinate, Brunn discovered a pterosaur snout. Starting in 1993, the quarry was systematically being excavated under the direction of Martin Röper and Monika Rothgaenger. Pterosaur finds were rare, with the exception of the type specimen of ''Bellubrunnus''. The snout fossil was accessioned by the Pa ...

2025 In Archosaur Paleontology
This article records new taxa of fossil Archosaur, archosaurs of every kind that are scheduled Binomial nomenclature, described during the year 2025, as well as other significant discoveries and events related to paleontology of archosaurs that are scheduled to occur in the year 2025. Pseudosuchians New pseudosuchian taxa General pseudosuchian research * Fitch, Kammerer & Sterling Nesbitt, Nesbitt (2025) describe Femur, femora of Poposauroidea, poposauroids similar to ''Poposaurus, Poposaurus gracilis'' from the Cumnock Formation, Cumnock and Pekin Formation, Pekin formations (Chatham Group; North Carolina, United States), expanding known geographical range of Late Triassic poposauroids. * McDavid (2025) discusses the validity and authorship of the name ''Prestosuchus'', considering the name ''Huenesuchus'' a junior synonym. Aetosaur research * A study on the histology of osteoderms of ''Stagonolepis, Stagonolepis olenkae'' is published by Błaszczeć & Antczak (2025). ...

Ctenochasmatid
Ctenochasmatidae is a group of pterosaurs within the suborder Pterodactyloidea. They are characterized by their distinctive teeth, which are thought to have been used for filter-feeding. Ctenochasmatids lived from the Late Jurassic to the Early Cretaceous periods. The earliest known ctenochasmatid remains date to the Late Jurassic Kimmeridgian age. Previously, a fossil jaw recovered from the Middle Jurassic Stonesfield Slate formation in the United Kingdom, was considered the oldest known. This specimen supposedly represented a member of the family Ctenochasmatidae,Buffetaut, E. and Jeffrey, P. (2012). "A ctenochasmatid pterosaur from the Stonesfield Slate (Bathonian, Middle Jurassic) of Oxfordshire, England." ''Geological Magazine'', (advance online publication) though further examination suggested it actually belonged to a teleosaurid stem-crocodilian instead of a pterosaur.
