Because it's Tennyson I imagine these behemoths to have pennants waving from neck ridges.

I would in no way, shape, or form take up your challenge - couldn't write poetry to save my life - but I enjoyed reading yours.

I think you've nailed the style. It sounds pretty and flows lyrically...which are odd descriptives when speaking about dinosaurs, but that kind of just proves it's good writing.

What fun! Titanic, ancient enemies confront each other in nineteenth-century cadences!

very nice,
