Duck's Dinner

Pharyngula: Plesiosaur poop!

A plesiosaur, an ancient duck,
With guts preserved—surprising luck
To find much more than fossil bones—
Had gastroliths (that's gizzard stones).
This "duck" had traveled far and wide.
We know, because the rocks inside
Were from a site three-hundred k
Or more away from where it lay.
And this poor beastie, snuffed before
It stopped to void its bowels once more,
Had bromalites (colonic stew
That's fossilized before it's poo).
We see this "duck" was want to suck
The benthic mud for clams in crud.
