Nearly 60 years ago, an amateur fossil collector named Francis Tully stumbled upon an incredibly peculiar fossil. The odd jumble of physical attributes – a tube-shaped body, eyes on stalks, and a long, skinny snout with a claw or jaw at the end – looked like they would be more at home in a Dr. Seuss book than in the swamps of Illinois.

The Field Museum's extensive collection of fossils helped answer a scientific question about a bizarre, ancient creature.
