505-million-year-old jellyfish fossils discovered, shedding light on evolution of ancient ecosystems

Fossils of 505-million-year-old jellyfish named Burgessomedusa phasmiformis discovered in the Burgess Shale.
Discovery provides evidence that jellyfish were free-swimming predators during the Cambrian period.
Fossils show jellyfish had bell-shaped bodies, tentacles for capturing prey, and other complex features.
Findings give insights into marine food webs and biodiversity during the Cambrian explosion.
Jellyfish fossils are exceptionally well-preserved, including soft tissues rarely seen in the fossil record.
