Shouldn't someone point out that not all dinosaurs were really big? Oh,
I've just done that.

As said before on the list, dinosaur get to be as small as a hummingbird,
the smallest possible size for an endotherm (now let's not start those two
hoary chestnuts again). Even among non-avian dinosaurs, there are still a
good number that are smaller than a human. So, while there were some real
whoppers, there were also some pretty puny ones as well and lots of other
sizes in between.
