The Great Tyrannosaurus Lived centuries ago;Through marshes wet and porous He rambled to and fro.
The most tremendous Lizard That ever browsed on meat,His length from A to Izzard Was forty-seven feet.
The Great Tyrannosaurus In habitude was notWhat one would call decorous -- He ate an awful lot.
Lamellibranchs in sixes, Iguanodons to spare,And Archaeopteryxes Comprised his bill of fare.
The Great Tyrannosaurus Of all the world was king;With trumpeting sonorous He swallowed everything.
When everything was swallowed Beneath the azure sky,What naturally followed? -- The Creature had to die.
The Great Tyrannosaurus That was so blithe and freeHath passed away before us; Then learn from him and me:
This earth can never nourish An appetite like his,So if you hope to flourish, Don't gobble all there is!
