Something Big Has Been Here
by Jack Prelutsky
Something big has been here,
What it was, I do not know,
for I did not see it coming,
and I did not see it go,
but I hope I never meet it,
if I do, I'm in a fix
for it left behind its footprints,
they are size nine-fifty-six.
I infer that ______ could have been here.
What is a dinosaur (or any large animal).
