They’re basically just like any other arthropod. Don’t even know why I bothered to post this
They varied in size from around 5-55 cm and were around during the Cambrian to middle Devonian (around 500 to 400 million years ago, give or take a few million years)

They are a very cool trype of animal, thank you for posting! Really sheds a light on just how unfamiliar life on Earth used to be
There are plenty of weird ones from the Cambrian
Glorious pre-chrodata fauna
To be fair, there are many bizarre non-chordates still alive, too
ribbon worms -- don't open while eating
Fossil pokemon look awesome this gen.
