Editing Pterosaur (section)

===Daily activity patterns===
Comparisons between the [[sclerotic ring|scleral ring]]s of pterosaurs and modern birds and reptiles have been used to infer daily activity patterns of pterosaurs. The pterosaur genera ''[[Pterodactylus]]'', ''[[Scaphognathus]]'', and ''[[Tupuxuara]]'' have been inferred to be [[Diurnality|diurnal]], ''[[Ctenochasma]]'', ''[[Pterodaustro]]'', and ''[[Rhamphorhynchus]]'' have been inferred to be [[nocturnal]], and ''[[Tapejara (pterosaur)|Tapejara]]'' has been inferred to be [[cathemeral]], being active throughout the day for short intervals. As a result, the possibly fish-eating ''Ctenochasma'' and ''Rhamphorhynchus'' may have had similar activity patterns to modern nocturnal seabirds, and the filter-feeding ''Pterodaustro'' may have had similar activity patterns to modern [[Anseriformes|anseriform]] birds that feed at night. The differences between activity patterns of the [[Paleobiota of the Solnhofen Formation|Solnhofen]] pterosaurs ''Ctenochasma'', ''Rhamphorhynchus'', ''Scaphognathus'', and ''Pterodactylus'' may also indicate [[niche partitioning]] between these genera.<ref>{{cite journal|author1=Schmitz, L. |author2=Motani, R. |year=2011 |title=Nocturnality in Dinosaurs Inferred from Scleral Ring and Orbit Morphology |journal=Science |volume=332 |issue= 6030|pages= 705–08|doi=10.1126/science.1200043 |pmid=21493820 |bibcode=2011Sci...332..705S|s2cid=33253407 }}</ref>
