Researchers at the Royal Ontario Museum have identified the oldest known species of swimming jellyfish, Burgessomedusa phasmiformis, in the fossil record. These well-preserved fossils from the Burgess Shale provide insights into the complex Cambrian food chain and demonstrate that large, swimming jellyfish with bell-shaped bodies existed over 500 million years ago. The discovery adds to our understanding of the evolution of life on Earth and highlights the remarkable preservation of delicate animals in the Burgess Shale.

The oldest species of swimming jellyfish, Burgessomedusa phasmiformis, has been discovered in 505 million-year-old fossils found at Burgess Shale in Canada. The well-preserved fossils provide insight into the evolutionary history of jellyfish, which have been difficult to study due to their delicate nature. The discovery suggests that the Cambrian food chain was more complex than previously thought, highlighting the diversity of life during that time period.

The discovery of a well-preserved, half-billion-year-old fossil of an ancient tunicate species called Megasiphon thylakos is shedding light on the evolutionary origins of vertebrates. Tunicates are the sister group of vertebrates, and this fossil provides insights into what early tunicates looked like and how they lived. The fossil resembles ascidiacea, suggesting that this body form is ancestral. The findings also suggest that tunicates originated around 500 million years ago. Further research is needed to uncover the evolutionary connections between tunicates, vertebrates, and other deuterostomes.

New research challenges the long-held belief that Anomalocaris canadensis, a prehistoric creature from over 500 million years ago, was a fearsome predator. Paleontologists have analyzed the appendages of Anomalocaris and found that they were not well-suited for crunching through the hard shells of trilobites, as previously thought. Instead, the researchers suggest that Anomalocaris plucked soft-bodied prey out of the water, such as comb jellies and other invertebrates. This new understanding of Anomalocaris' feeding habits provides a different perspective on the ancient creature's role in the Cambrian seas.

Biomechanical studies on Anomalocaris canadensis, an extinct apex predator from the Cambrian period, suggest that it was likely a fast and agile swimmer that targeted soft prey in the open water rather than hard-shelled creatures on the ocean floor. The research challenges previous assumptions about the predator's ability to process hard food and sheds light on the complexity of Cambrian food webs.
