The presence of LAGs in Timimus (which may not be an ornithomimid) was
used as evidence for hibernation. Such LAGs are not present in
hypsilophodontids like Leaellynasaura, leading the authors to suggest
they may have been active all year round (the enlarged optical lobes of
Leaellynasaura sited as a possible adaptation to constant winter
darkness). <<

Yup. Already have it. (the paper and Dinosaurs of Darkness). My quest was for 
additional support besides what's in those references.
