Earliest enteropneust (acorn worm) fossil found, 500 million years old

Fossils of these soft-bodied acorn worms were found in mud dated back to the Cambrian period, placing them a further 200 million years back in time than previously thought. That’s great, but all I can think of is “holy crap, dick worms”.

Seriously, have a look.
