It's interesting that today's two large clades of flying animals (_Neornithes_

There was a fairly recent suggestion that anurognathids might have been nocturnal insect-catchers, on account of their big eyes and wide mouths. AFAIK, the notion that anurognathids caught flying insects on the wing is not new, but the suggestion that they did so at night is.
