If you, like me, are something of a paleo-romantic,

Swooning over dinosaurs both fearsome and gigantic,

Come feast your eyes on new reports the bone-hunters have brought us:

“Fearing nothing” means its name – the mighty beast Dreadnoughtus!

Seven times as heavy as Tyrannosaurus rex,

This gentle vegan creature boasted tons of muscle flex.

Patagonian earth under its massive feet would quake,

What a silhouette at dawn a family would make!

Even ‘mongst Titanosaurids, this one breaks the ceiling,

A shoulder blade as tall as I am – God, it sets me reeling.

On top of that, when this one died, it wasn’t yet mature …

How much more would it have grown? We can not be quite sure.

3D-scanning, high-tech models try to help us see one,

But why were creatures bigger then? What was it like to be one?

Children are the best at this, working on all fours,

Today, I think I’ll try it too: fear nothing, shake the floors!

AGU25, the premier Earth and space science conference, takes place December 15-19, 2025 in New Orleans, Louisiana. This year’s theme—Where Science Connects Us—puts in focus how science depends on connection, from the lab to the field to the ballot box. Once again, Lamont-Doherty Earth Observatory and Columbia Climate School scientists, experts, students, and educators are playing an active role, sharing our research and helping shape the future of our planet. #AGU25 Learn More
