Avian cerebellar floccular fossa size is not a proxy for flying ability in birds
Extinct animal behavior has often been inferred from qualitative assessments of relative brain region size in fossil endocranial casts. For instance, flight capability in pterosaurs and early birds has been inferred from the relative size of the cerebellar flocculus, which in life protrudes from the lateral surface of the cerebellum....Walsh, Stig A ; Iwaniuk, Andrew N ; Knoll, Monja A ; Bourdon, Estelle ; Barrett, Paul M …

Inner ear anatomy is a proxy for deducing auditory capability and behaviour in reptiles and birds
Inferences of hearing capabilities and audition-related behaviours in extinct reptiles and birds have previously been based on comparing cochlear duct dimensions with those of living species. However, the relationship between inner-ear bony anatomy and hearing ability or vocalization has never been tested rigorously in extant or fossil taxa. Here, micro-computed...Walsh, Stig A ; Barrett, Paul M ; Milner, Angela C ; Manley, Geoffrey ; Witmer, Lawrence M
