Talk:Scleral Ring

Implications for behavior
The article on pterosaurs says,


 * Comparisons between the scleral rings of pterosaurs and modern birds and reptiles have been used to infer daily activity patterns of pterosaurs;

specifically with reference to whether a species was diurnal or nocturnal. It would be useful if the present article explained how sclerotic (or scleral) rings may indicate such patterns of activity. J. D. Crutchfield &#124; Talk 18:43, 9 June 2014 (UTC)
