Jellyfish, categorized as medusozoans, have umbrella-shaped bodies and stinging tentacles. They are part of the Cnidaria group, which includes ancient species like corals and sea anemones. The discovery of Burgessomedusa phasmiformis fossils at the Burgess Shale site suggests the presence of large, bell-shaped jellyfish that swam freely over half a billion years ago. The Burgess Shale is a remarkable source of well-preserved specimens, shedding light on the ancient marine ecosystem and species interactions. These fossils help unravel the history of free-swimming jellyfish. Burgessomedusa phasmiformis likely played a significant role in the ancient marine food chain with its distinctive features, such as 90 finger-like tentacles for capturing prey. This discovery enriches our understanding of Earth’s evolutionary journey and adds to the diverse collection of species found in the Burgess Shale.
