I found a fossil in the park today –
An ammonite in iron grey,
Hardly rare, this type of fare,
They get found in their scores –
They all died by their millions
Till they died with the dinosaurs.
But all the rock round here today
Is built on London Clay –
On the scene in the Eocene,
With its lush and tropic shores,
Yet laid down some ten million
After the end of the dinosaurs.
I guess the path on which it sat
Was older than all that.
I guess its gravel had to travel
From who knows where, of course –
He’s an immigrant, like the millions
Coming here since the dinosaurs.
Though I suspect it’s less of an ammonite and more of a snail.
