My favourite extinct monster is anomalocaris. Creatures during the Cambrian period were so strange looking. Which makes them interesting! Anomalocaris was basically a gigantic brine shrimp with an appetite for anything smaller than itself. Which was everything, because it was the largest animal in the world when it was alive!

Guess I just always found it fascinating that half a billon years ago, Earth was essentially an alien planet. Things could’ve ended up very differently...

So probably the weirdest Cambrian creature was this little beast. It's called Opabinia.

About the size of a mouse, and probably a relative of anomalocaris. Opabinia is mostly unlike any other creature we've ever found on Earth. Five eyes and an odd little trunk with a grabby thing on the end. In an incredibly bizarre form of convergent evolution, it probably used this appendage to eat in much the same way an elephant uses its trunk!

Oh, interesting. Late Carboniferous. Interesting little beastie, I hadn't heard of it before!
