When a group of paleontologists dusted off a group of fossils that had been sitting on the shelf at the Royal Ontario Museum in Toronto, Canada since the 1980s, they uncovered a spooky organism with a bell-shaped body and about 90 stubby tentacles extending out from its rim.
The 505 million-year-old fossil revealed the oldest known species of swimming jellyfish, which the research team named Burgessomedusa phasmiformis, according to a study published today in the Proceedings of the Royal Society B.
