Dinosaur poem I once wrote for my kids

Maybe ten years ago or so or more, I wrote them this little doggerel number while we were at Rye Playland early in the summer.  I recently spotted it in my closet.  With apologies to Robert Bakker (for his dinosaur novel Raptor Red), and for the historical inaccuracies regarding which species actually coexisted with velociraptors:

The duckbill herd had drunk its fill

Thought Raptor Red: "It's time to kill."

Her sisters three were close at hand

And by the grove they made their stand

The duckbill herd was acting shy

And sticking close as they went by

A flash of claws, a snarl of teeth

The sisters leaped, and pinned beneath

A duckbill chick, who soon was still

The herd all honked and fled downhill

And stomped beneath their thundering feet

An acrocanthosaur who'd planned to eat

The raptors' kill as stolen meat

The raptors stretched and ate their fill

And lay down in the grass until

Another acro spied their prize

But by that time no meat was left

Except some for the pterodactyls and the flies.
