We found your partial left
upper arm bone near Sandsfoot
in the lower Kimmeridge Clay
and asked the Romans where
that was and their reply came
Duria.

And by the size of it
we think you are eighty-two
feet long, which feels big so
asked the Greeks “what’s big?” and
they thought the Titans
might be.

We call that bit
your deltopectoral crest
or crista as it peaks
where your deltoids meet
your humerus and so you are
our humerocristatus.

You are your arm bone
we found that first and now
we wonder who was the last of you
to wander our Jurassic coast.
