Formerly known as Brontosaurus,
He was bigger than a Broadway chorus.
A vegan with a taste for grub
Like tender plants and savory shrub.
His appetite for stones from streams
Helped him grind up hearty greens.
His neck and tail, long and sleek,
Were not so good for hide-and-seek.
Slow of foot and small of brain,
He lost his way down memory lane.
