"518-Million-Year-Old Giant Carnivorous Worms Discovered in Greenland's Arctic"

A team of scientists has discovered fossils of a half-billion-year-old predatory worm, Timorebestia, in the high-Arctic zone of North Greenland. These ancient creatures, which were among the largest predators of the Early Cambrian period, are related to modern arrow worms but were significantly larger, reaching up to 30 centimeters in length. The discovery provides new insights into the evolution of early marine ecosystems and the predatory dominance of these ancient worms before the rise of arthropods. The findings, including the preservation of unique nerve structures, support the hypothesis that Timorebestia and similar fossils are closely related to arrow worms, contributing to our understanding of early animal evolution. The research was published in the journal Science Advances.
