this little fellow is an Australian Water Dragon, I have several in my garden, the largest is about 12 inches long; it comes out to lie in the sun in the morning...and his little motor doesn't start running until he's been sunning himself for an hour or so...so I try to imagine how long it would take for a huge dino (if it was a reptile) to get warm enough to get going...and I think to myself - he'd be lucky to get going before the sun went down!

If cold blooded, and assuming that the Earth wasn't closer to the Sun 65 million years ago. ;')

so I try to imagine how long it would take for a huge dino (if it was a reptile) to get warm enough to get going...Volume to surface area ratio.
A=4 pi r2
V= (4/3) pi r3
V/A= (4/3) pi r3 / 4 pi r2
V/A=r/3
IOW big things retain heat better than small things all other factors being the same.
