The Royal Ontario Museum now holds close to 200 specimens that were used to learn more about the internal anatomy and tentacles of ancient jellyfish, with some specimens measuring more than seven inches long.

This discovery leaves no doubt they were swimming about at that time,” study co-author and University of Toronto PhD candidate Joe MoysiukThis study uses fossil specimens that were discovered at the Burgess Shale during the late 1980s and 1990s.
