dinosaur humps (was Re: A Whole Bunch Of Questions)
From: "Mickey Mortimer" <Mickey_Mortimer111@msn.com>
I prefer Bailey's evidence for humps. Certainly better than any >published
argument for sails.
Perhaps better than any published argument for >thermodynamic< sails, but
what about display, mimicry, etc.? Bailey barely touches on the other
possibilities. He insists that the transverse narrowness (and sagittal
broadness) of the neural spines indicate an increased resistance to strain
in the anteroposterior plane (thus implying a muscular hump of some sort).
But don't most dinosaur neurals, whether tall or not, exhibit similar
dimensions? Why couldn't dinosaurs have just elongated them to form a sail
without changing the aforementioned dimensions?
