If ever an article needed an artist's rendition.

I'd love to see the massive jaw structure to see how afraid I should be for my toes if some crazy billionaire decides to do a Cambrian Park. This worm is about a foot long after all.

The article in Science has more details, including a higher resolution variant of the bluish artistic rendition from the right upper corner.

The jaws have been preserved only partially.

The jaws of even a giant arrow worm would not be very dangerous for your toes, because they are designed to hook any prey, to prevent its escaping, like also the teeth of many fish, and not for cutting or crushing. Nevertheless, it seems that the jaws of this ancestor of the arrow worms were less similar to those of the modern arrow worms than to the jaws of the so-called gnathostomulids, so they might have had a stronger crushing action than in modern arrow worms.
