After observing chickens and turkeys a bit more closely, I've observed them not only sunbathing in a very "mammalian lounging" position, but also falling asleep in that position. I am therefore obliged to discard my preconceived notions and conclude that, yes, larger non-avian dinosaurs were probably capable of lounging like lions, or kicking back like kangaroos.<br /><br />Thanks, guys, for the great feedback!alaskanimehttps://www.blogger.com/profile/08299289638870579061noreply@blogger.comtag:blogger.com,1999:blog-1774939752964547806.post-42033992727494486982013-03-17T17:41:31.527-07:002013-03-17T17:41:31.527-07:00Ground-feeding birds like turkeys or peafowl can a...Ground-feeding birds like turkeys or peafowl can adopt a lounge-like posture when dust bathing or sun bathing. I suspect that tree-dweller anatomy and a fused backbone are probably pretty significant when explaining why most birds don't lounge like a mammal, so one need not necessarily assume that dinosaurs would follow suit.quarksparrowhttps://www.blogger.com/profile/02728570768963854509noreply@blogger.comtag:blogger.com,1999:blog-1774939752964547806.post-49079990882526421282013-03-17T13:40:25.700-07:002013-03-17T13:40:25.700-07:00At least some theropods sat on their belly, large ...At least some theropods sat on their belly, large bird-style:<br /><br />http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0004591Thomas Holtzhttps://www.blogger.com/profile/05580730835586277579noreply@blogger.comtag:blogger.com,1999:blog-1774939752964547806.post-79898844221809429212013-03-17T06:39:41.890-07:002013-03-17T06:39:41.890-07:00I think that for the most part, dinos wer elikely ...I think that for the most part, dinos wer elikely belly-squaters. However, if elephants can lay and get up, one wonders if, if the mobility of the limbs is sufficient, a giant ornithischians could. I have my doubts about tyrannosaurs, though; the issue is not of mass or delicacy, but leverage, and whether or how a tyrannosaur would ascend from a prone and side-ways posture into one in which it could stand up. Quadrupeds, even sauropods, have it easier, because the forelimb assists the hind in providing leverage: Forelimb sprawls, lifting forequarters up, which twists body up and over, allowing hindlimb position and leverage to push it over onto a quadrupedal stance, at which point the animal just "stands up." This is all hypothetical, but its how elephants do it. Mobility, weight, and leverage are issues for giant quadrupeds, but likely more favorable than giant bipeds. It seems squatting is a better model for them.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-1774939752964547806.post-46109634580063026542013-03-17T06:07:01.492-07:002013-03-17T06:07:01.492-07:00Would a sleeping position like that of Mei long wo...Would a sleeping position like that of Mei long work for larger, unfeathered, Dinosaurs?Hypnotosovhttps://www.blogger.com/profile/11469293434683944221noreply@blogger.comtag:blogger.com,1999:blog-1774939752964547806.post-43792548228019486982013-03-17T05:52:35.341-07:002013-03-17T05:52:35.341-07:00I think the key is on dinosaur anatomy.

Crocodiles' bodies are wider than they are tall, and their legs stick out sideways, so that kind of resting position would be rather unconfortable and unnatural for them. Birds on the other hand also have very specialized anatomies, most need to be careful with theirs wings and feathers so as not to damage them, and are all bipedal. So in terms of body plan and general behaviour, non-avian dinosaurs could well have some mammalian-looking activities, like louging on their sides.Julio Lacerdahttps://www.blogger.com/profile/09075439567916698811noreply@blogger.comtag:blogger.com,1999:blog-1774939752964547806.post-8658114564508139092013-03-17T05:51:23.332-07:002013-03-17T05:51:23.332-07:00Good question.
