Not so many thousand years before 
these old rocks were the bones of the haplocanthosaur 
Old, 
Old rocks 
Old 
Tall as a house, 
gentle as a mouse... 
Bare bones are petrified 
Later they are classified 
A skeleton may indicate, 
imagination animates 
The mind's eye does need to see 
the fluid grace and subtlety 
of animals fitted perfectly 
to a world not like the one we see 

The bones of a flying animal now called the pterosaur 
have been found a hundred miles 
from the presumed seashore 
Old, 
Old rocks 
Old 
One kind had teeth like a whale's 
One kind had a hair covering 
One kind would've been 37 feet from wing to wing... 
Bare bones are petrified 
Later they are classified 
A skeleton may indicate, 
imagination animates 
The mind's eye does need to see 
the fluid grace and subtlety 
of animals fitted perfectly 
to a world not like the one we see 

Here's the sort of bird that we don't see 
In some of the books it's not treated 
quite respectfully 
Old, 
Old rocks 
Old, 
Old rocks 
Has the short end of the stick been given archaeopteryx?
