How Did Packs of Sauropods

Tune: Irving Berlin's "Puttin' on the Ritz"
See http://news.discovery.com/animals/dinosaurs/dinosaur-farts-120507.htm

How did packs
Of sauropods
Survive attacks
Against the odds,
And save their necks?
Pootin' at the Rex.

To their cores
The hills are quaking:
Herbivores
Are simply making
Sphinctres flex,
Pootin' at the Rex.

Picture, then, this prehistoric chorus—
Methane blizzard.
Re-defining terms like "Brontosaurus
('Thunder lizard')."

Re-release
That work of art;
Re-name the piece
Jurassic Fart—
You'll earn big checks,
Pootin' at the Rex.
