the brontosaurus came back

brontosaurus?
or apatosaurus?
that, I hear you chorus,
is the question
both beasts of a similar dimension
both with a fancy neck extension
and you’d definitely have felt their humongous stomp
as you hid the other side of the swamp

both were examples of sauropoda
and lived somewhere between Wyoming and Dakota
though things have changed around considerably
since the late Jurassic period, probably

then in nineteen hundred and three
Elmer Riggs said publicly
these sauros were the same
so Riggs is to blame
(Riggs was an eminent palaeontologist
who’d added another dinosaur to the list
the beautifully proportioned Brachiosaurus
which had nice long legs and was easily the tallest)

so the scientists endlessly quibbled
about the dimensions of bones the collectors scribbled
and for years it was literally neck and neck
with poor brontosaurus held back in check

but now the consensus seems to be
both beasts are distinct proportionally
and can proudly stand in the city museum
(just don’t crick your neck when you stand to see ‘em)
