pachycephalosaurus

I'm reading poetry for my children's literature class, and I wanted to share my favorite one.

Among the later dinosaurs
Though not the largest, strongest,
PACHYCEPHALOSAURUS had
The name that was the longest.

Yet he had more than syllables,
As you may well suppose.
He had great knobs upon his cheeks
And spikes upon his nose.

Ten inches thick, atop his head,
A bump of bone projected.
By this his brain, though hardly worth
Protecting, was protected.

No claw or tooth, not tree that fell
Upon his head kerwhacky,
Could crack or crease or jar or scar
That stony part of Paky.

And so he nibbled plants in peace
And lived untroubled days.
Sometimes, in fact, as Paky proved,
To be bonehead pays.
