So it’s Poetry Day, and I was reminded of this terrible poem I wrote while I was writing my dissertation:
A poem by Ali Nabavizadeh
The predentary bone is one to ponder;
Unique, peculiar, and full of wonder.
It sat in front of many a dinosaur jaw;
In hopes that plants are what it saw.
They came triangular, round, or square;
And no other jawbone could compare.
For it was on its own, all lonesome and sad;
Thinking of the counterpart it never had.
I cannot stress enough, however;
That this tiny bone did much to sever;
The innocent plant life that grew around.
It would chop it up before making a sound.
Stegosaurus and those duck-billed creatures;
Are only a few who shared this feature.
Ankylosaurus was also among them
And that Triceratops, with three horns; a gem.
Heterodontosaurids—they started it out,
(Or at least that’s what phylogenies seem to talk about).
Who knows, though? It’s hard to tell these days;
Because us paleontologists cant agree on what trees go—and what stays.
The function of this peculiar bone;
Has long been thought to be nipping plants on its own.
I’m willing to bet my life, however;
That this bone did much more than just sever.
It sat in the middle, proud and bold;
With two dentary bones on either side that rolled;
Around their long axes as the animal chewed;
While rotating around each predentary joint—‘Yum, food’.
The predentary bone would stay just still;
As the other bones would show off their skill;
Chewing the plants on both sides of the jaw;
While Mr. Predentary grabbed more food to gnaw.
So you see, my friends, predentaries worked wonders;
Although researching their function gives me mental blunders.
It is safe to say that, though it does have some class;
The predentary bone is just a pain in my ass.
